Cell-Edge-Aware Precoding for Downlink Massive MIMO Cellular Networks (2017)

We propose a cell-edge-aware (CEA) zero forcing (ZF) precoder that exploits the excess spatial degrees of freedom provided by a large number of base station (BS) antennas to suppress inter-cell interference at the most vulnerable user equipments (UEs). We evaluate the downlink performance of CEA-ZF, as well as that of a conventional cell-edge-unaware (CEU) ZF precoder in a network with a random BS topology. Our analysis and simulations show that the proposed CEA-ZF precoder outperforms CEU-ZF precoding in terms of (i) aggregate per-cell data rate, (ii) coverage probability, and (iii) 95%-likely, or edge user, rate. In particular, when both perfect channel state information and a large number of antennas N are available at the BSs, we demonstrate that the outage probability under CEA-ZF and CEU-ZF decay as 1/N <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and 1/N, respectively. This result identifies CEA-ZF as a more effective precoding scheme for massive multiple-input multiple-output (MIMO) cellular networks. Our framework also reveals the importance of scheduling the optimal number of UEs per BS, and confirms the necessity to control the amount of pilot contamination received during the channel estimation phase.

Computationally Intelligent Image Processing Techniques for Crack Detection in Structural Components from Imaged Data (2016)

This effort focuses on automatically detecting cracks in structural components from imaged data. Currently, fluorescent penetrant inspection (FPI) identifies cracks in engine components such as blades, disks, casings, etc. Alternatives to FPI are needed and advanced, non-destructive inspection (NDI) methods are under development to improve damage detection limits in an automated manner through the incorporation of computational techniques. Ultrasonic excitation is utilized in conjunction with infrared (IR) imaging to detect crack-like defects using Sonic Infrared (SIR) imaging. An automated process to detect cracks given a sequence of SIR images is developed. This process sorts the SIR images, performs a reference subtraction, calculates the largest image difference, creates structural elements, performs morphological filtering, and labels potential crack locations. The outlined crack detection method developed is applied to 14 industrial type blades from SIR image sequences of representative turbine engine components. Computationally intelligent image processing techniques were successfully able to identify cracks in all 14 blades, where the blades were previously assessed using FPI. False crack identifications due to localized heating of the holding mechanism of the part were also observed in addition to the actual crack locations. With the addition of other image processing techniques, these false-calls have the potential to be reduced. Using image processing techniques to automatically detect crack-like defects is a viable tool to use as an alternative method, or in conjunction with FPI, to improve damage detection, reduce manpower requirements, and chemical usage associated with FPI.
Modulation of epithelial neoplasia and lymphoid hyperplasia in PTEN +/- mice by the p85 regulatory subunits of phosphoinositide 3-kinase (2005)

Mice with heterozygous deletion of the PTEN tumor suppressor gene develop a range of epithelial neoplasia as well as lymphoid hyperplasia. Previous studies suggest that PTEN suppresses tumor formation by acting as a phosphoinositide phosphatase to limit signaling by phosphoinositide 3-kinase (PI3K). Here, we examined the effect of deleting various regulatory subunits of PI3K (p85alpha and p85beta) on epithelial neoplasia and lymphoid hyperplasia in PTEN+/- mice. Interestingly, we found the loss of one p85alpha allele with or without the loss of p85beta led to increased incidence of intestinal polyps. Signaling downstream of PI3K was enhanced in the PTEN+/-p85alpha+/-p85beta-/- polyps, as judged by an increased fraction of both cells with cytoplasmic staining of the transcription factor FKHR and cells with positive staining for the proliferation marker Ki-67. In contrast, the incidence of prostate intraepithelial neoplasia was not significantly altered in PTEN+/- mice heterozygous for p85alpha or null for p85beta, whereas the fraction of proliferating cells in prostate intraepithelial neoplasia was reduced in mice lacking p85beta. Finally, there was no significant change in T lymphocyte hyperplasia in the PTEN+/- mice with various p85 deletions, although anti-CD3-stimulated AKT activation was somewhat reduced in the p85alpha+/- background. These results indicate that decreasing the levels of different p85 regulatory subunits can result in enhanced PI3K signaling in some tissues and decreased PI3K signaling in others, supporting the model that, although p85 proteins are essential for class I(A) PI3K signaling, they can function as inhibitors of PI3K signaling in some tissues and thus suppress tumor formation.
Non-volatile Clocked Spin Wave Interconnect for Beyond-CMOS Nanomagnet Pipelines (2015)

Abstract The possibility of using spin waves for information transmission and processing has been an area of active research due to the unique ability to manipulate the amplitude and phase of the spin waves for building complex logic circuits with less physical resources and low power consumption. Previous proposals on spin wave logic circuits have suggested the idea of utilizing the magneto-electric effect for spin wave amplification and amplitude- or phase-dependent switching of magneto-electric cells. Here, we propose a comprehensive scheme for building a clocked non-volatile spin wave device by introducing a charge-to-spin converter that translates information from electrical domain to spin domain, magneto-electric spin wave repeaters that operate in three different regimes - spin wave transmitter, non-volatile memory and spin wave detector and a novel clocking scheme that ensures sequential transmission of information and non-reciprocity. The proposed device satisfies the five essential requirements for logic application: nonlinearity, amplification, concatenability, feedback prevention and complete set of Boolean operations.

The BRG1 Chromatin Remodeler Protects Against Ovarian Cysts, Uterine Tumors, and Mammary Tumors in a Lineage-Specific Manner (2012)

The BRG1 catalytic subunit of SWI/SNF-related complexes is required for mammalian development as exemplified by the early embryonic lethality of Brg1 null homozygous mice. BRG1 is also a tumor suppressor and, in mice, 10% of heterozygous (Brg1(null/+)) females develop mammary tumors. We now demonstrate that BRG1 mRNA and protein are expressed in both the luminal and basal cells of the mammary gland, raising the question of which lineage requires BRG1 to promote mammary homeostasis and prevent oncogenic transformation. To investigate this question, we utilized Wap-Cre to mutate both Brg1 floxed alleles in the luminal cells of the mammary epithelium of pregnant mice where WAP is exclusively expressed within the mammary gland. Interestingly, we found that Brg1(Wap-Cre) conditional homozygotes lactated normally and did not develop mammary tumors even when they were maintained on a Brm-deficient background. However, Brg1(Wap-Cre) mutants did develop ovarian cysts and uterine tumors. Analysis of these latter tissues showed that both, like the mammary gland, contain cells that normally express Brg1 and Wap. Thus, tumor formation in Brg1 mutant mice appears to be confined to particular cell types that require BRG1 and also express Wap. Our results now show that such cells exist both in the ovary and the uterus but not in either the luminal or the basal compartments of the mammary gland. Taken together, these findings indicate that SWI/SNF-related complexes are dispensable in the luminal cells of the mammary gland and therefore argue against the notion that SWI/SNF-related complexes are essential for cell survival. These findings also suggest that the tumor-suppressor activity of BRG1 is restricted to the basal cells of the mammary gland and demonstrate that this function extends to other female reproductive organs, consistent with recent observations of recurrent ARID1A/BAF250a mutations in human ovarian and endometrial tumors.

Human dendritic cells sequentially matured with CD4+ T cells as a secondary signal favor CTL and long-term T memory cell responses (2012)

Dendritic cells (DCs) are professional antigen-presenting cells involved in the control and initiation of immune responses. In vivo, DCs exposed at the periphery to maturation stimuli migrate to lymph nodes, where they receive secondary signals from CD4+ T helper cells. These DCs become able to initiate CD8+ cytotoxic T lymphocyte (CTL) responses. However, in vitro investigations concerning human monocyte-derived DCs have never focused on their functional properties after such sequential maturation. Here, we studied human DC phenotypes and functions according to this sequential exposure to maturation stimuli. As first signals, we used TNF-&amp;#945;/polyI:C mimicking inflammatory and pathogen stimuli and, as second signals, we compared activated CD4+ T helper cells to a combination of CD40-L/ IFN-&amp;#947;. Our results show that a sequential activation with activated CD4+ T cells dramatically increased the maturation of DCs in terms of their phenotype and cytokine secretion compared to DCs activated with maturation stimuli delivered simultaneously. Furthermore, this sequential maturation led to the induction of CTL with a long-term effector and central memory phenotypes. Thus, sequential delivery of maturation stimuli, which includes CD4+ T cells, should be considered in the future to improve the induction of long-term CTL memory in DC-based immunotherapy.
Holographic Speckle-Based Authentication Paradigm (2019)

An approach for a physical authentication scheme is proposed relying on the irreversible and nonconvex nature of computer-generated holograms. This is demonstrated by proof-of-principle meta-holograms projecting uniquely speckled 2D barcode images.
The role of p19 and p21 H-Ras proteins and mutants in miRNA expression in cancer and a Costello syndrome cell model (2015)

These results allow us to conclude that the H-Ras G12S mutation plays an important role in miRNA expression and open up a new line of study to understand the consequences of this mutation on Costello syndrome. Furthermore, they suggest that oncogenes may have a sufficiently important impact on miRNA expression to promote the development of numerous cancers.
Roles of coronary circulation as a determinant of the left ventriculo-arterial interaction. (1985)

We investigated how coronary circulation influences the ventriculo-arterial interaction. For the quantitative analysis of this interaction, we proposed a simple framework where both ventricular property and vascular property were expressed as the end-systolic pressure-volume relationship. Combining this analysis with experimental data indicated the interactive nature of ventricular function that varied with loading condition through coronary circulation. Effects of regional ischemia on the ventriculo-arterial interaction was also analyzed. The loading condition insensitivity, simplicity and adequacy of the end-systolic pressure-volume relationship of ventricle made it possible to analytically couple the ventricle with arterial system providing a useful view in understanding the complex hydraulic interaction between the ventricle and arterial system.

Direct Immobilization of Cholesteryl-TEG-Modified Oligonucleotides onto Hydrophobic SU-8 Surfaces (2007)

We introduce a rapid, simple one-step procedure for the high-yield immobilization of cholesteryl-tetraethyleneglycol-modified oligonucleotides (chol-DNA) at hydrophobic sites made of SU-8 photoresist. Topographic structures of SU-8 were microfabricated on microscope glass coverslips sputtered with a Ti/Au layer. Upon application, chol-DNA adsorbed to the SU-8 structures from solution, leaving the surrounding gold surface free of chol-DNA. chol-DNA immobilization is complete within 15 min and yields a surface coverage in the range of 20-95 pmol/cm(2), which corresponds to a film density of 10(12)-10(13) molecules/cm(2). chol-DNA immobilization is stable and can be sustained despite rinsing, drying, dry storage for several hours, and rehydration of chips. Furthermore, complementary DNA in solution hybridizes efficiently to immobilized chol-DNA.
Experimental and quantum‐chemical studies of 1H, 13C and 15N NMR coordination shifts in Pd(II) and Pt(II) chloride complexes with methyl and phenyl derivatives of 2,2′‐bipyridine and 1,10‐phenanthroline (2007)

1H, 13C and 15N NMR studies of platinide(II) (M=Pd, Pt) chloride complexes with methyl and phenyl derivatives of 2,2'-bipyridine and 1,10-phenanthroline [LL=4,4'-dimethyl-2,2'-bipyridine (dmbpy); 4,4'-diphenyl-2,2'-bipyridine (dpbpy); 4,7-dimethyl-1,10-phenanthroline (dmphen); 4,7-diphenyl-1,10-phenanthroline (dpphen)] having a general [M(LL)Cl2] formula were performed and the respective chemical shifts (delta1H, delta13C, delta15N) reported. 1H high-frequency coordination shifts (Delta1Hcoord=delta1Hcomplex-delta1Hligand) were discussed in relation to the changes of diamagnetic contribution in the relevant 1H shielding constants. The comparison to literature data for similar [M(LL)(XX)], [M(LL)X2] and [M(LL)XY] coordination or organometallic compounds containing various auxiliary ligands revealed a large dependence of delta1H parameters on inductive and anisotropic effects. 15N low-frequency coordination shifts (Delta15Ncoord=delta 15Ncomplex-delta15Nligand) of ca 88-96 ppm for M=Pd and ca 103-111 ppm for M=Pt were attributed to both the decrease of the absolute value of paramagnetic contribution and the increase of the diamagnetic term in the expression for 15N shielding constants. The absolute magnitude of Delta15Ncoord parameter increased by ca 15 ppm upon Pd(II)-->Pt(II) transition and by ca 6-7 ppm following dmbpy-->dmphen or dpbpy-->dpphen ligand replacement; variations between analogous complexes containing methyl and phenyl ligands (dmbpy vs dpbpy; dmphen vs dpphen) did not exceed+/-1.5 ppm. Experimental 1H, 13C, 15N NMR chemical shifts were compared to those quantum-chemically calculated by B3LYP/LanL2DZ+6-31G**//B3LYP/LanL2DZ+6-31G*, both in vacuo and in DMSO or DMF solution.
CO2-philic Oligomers as Novel Solvents for CO2Absorption (2010)

Desirable properties for an oligomeric CO2-capture solvent in an integrated gasification combined cycle (IGCC) plant include high selectivity for CO2 over H2 and water, low viscosity, low vapor pressure, low cost, and minimal environmental, health, and safety impacts. The neat solvent viscosity and solubility of CO2, measured via bubble-point loci and presented on a pressure−composition diagram (weight basis), and water miscibility in CO2-philic solvents have been determined and compared to results obtained with Selexol, a commercial oligomeric CO2 solvent. The solvents tested include polyethyleneglycol dimethylether (PEGDME), polypropyleneglycol dimethylether (PPGDME), polypropyleneglycol diacetate (PPGDAc), polybutyleneglycol diacetate (PBGDAc), polytetramethyleneetherglycol diacetate (PTMEGDAc), glyceryl triacetate (GTA), polydimethyl siloxane (PDMS), and perfluorpolyether (PFPE) that has a perfluorinated propyleneglycol monomer unit. Overall, PDMS and PPGDME are the best oligomeric solvents tested and exhibit properties that make them very promising alternatives for the selective absorption of CO2 from a mixed gas stream, especially if the absorption of water is undesirable.
Tasks, stability, architecture, and compute: Training more effective\n learned optimizers, and using them to train themselves (2020)

Much as replacing hand-designed features with learned functions has\nrevolutionized how we solve perceptual tasks, we believe learned algorithms\nwill transform how we train models. In this work we focus on general-purpose\nlearned optimizers capable of training a wide variety of problems with no\nuser-specified hyperparameters. We introduce a new, neural network\nparameterized, hierarchical optimizer with access to additional features such\nas validation loss to enable automatic regularization. Most learned optimizers\nhave been trained on only a single task, or a small number of tasks. We train\nour optimizers on thousands of tasks, making use of orders of magnitude more\ncompute, resulting in optimizers that generalize better to unseen tasks. The\nlearned optimizers not only perform well, but learn behaviors that are distinct\nfrom existing first order optimizers. For instance, they generate update steps\nthat have implicit regularization and adapt as the problem hyperparameters\n(e.g. batch size) or architecture (e.g. neural network width) change. Finally,\nthese learned optimizers show evidence of being useful for out of distribution\ntasks such as training themselves from scratch.\n
Novel band-pass ΔΣ modulators based on a modified adder-less feed-forward structure (2017)

Two Band-Pass (BP) Discrete Time (DT) ΔΣ modulators are proposed in this paper. In both cases, the drawback of high-speed power-hungry adder is tackled by proposing a modified unity signal transfer function (STF) adder-less feedforward structure. The first proposed BP DT ΔΣ modulator is a conventional adder-less multi-stage noise shaping (MASH) ΔΣ modulator, while the noise leakage problem, caused by the mismatches between analog loop filter and digital cancellation logic (DCL), is mitigated by proposing a second topology in which the DCL is omitted. All of these features make the proposed modulators suitable for low-voltage and low-power applications, while the second proposed topology features a higher robustness against noise leakage and mismatch. Time-domain behavioral simulations show a 0-dBFS overload input level for the proposed architectures while the DC-gain is relaxed for the second proposed architecture such that a 67-dB S NDR can be obtained with only a 30-dB amplifier DC-gain at a -20-dBFS input signal level.
