Downlink Channel Assignment and Power Control for Cognitive Radio Networks (2008)

We consider a cognitive radio network in which a set of base stations make opportunistic spectrum access to support fixed-location wireless subscribers within their cells. The spectrum of interest is divided into independent channels using frequency division multiple access (FDMA) and is licensed to the operator of a primary network. Channel assignment and power control must be carried out in the cognitive network so that no excessive interference is caused to users of the primary network. We are interested in the downlink channel/power allocation problem for the cognitive radio network, with the objective of maximizing the total number of active subscribers that can be supported. Here, we assume that each subscriber of the cognitive network can be either active or idle and only active subscribers require downlink transmission. We first consider the case when global knowledge of all active subscribers is available for making control decisions. In that case, a downlink channel/power allocation scheme that maximizes the number of supported subscribers can be obtained by solving a mixed-integer linear programming. We also propose a suboptimal scheme that can be obtained at lower complexity based on a dynamic interference graph. We then consider the case when control decisions can only be made based on local knowledge of active subscribers within each cell. For that, we propose a scalable two-phase channel/power allocation scheme. Numerical results show the effectiveness of our proposed schemes.
Distributed CSI Acquisition and Coordinated Precoding for TDD Multicell MIMO Systems (2015)

Several distributed coordinated precoding methods exist in the downlink multicell multiple-input-multiple-output (MIMO) literature, many of which assume perfect knowledge of received signal covariance and local effective channels. In this paper, we let the notion of channel state information (CSI) encompass this knowledge of covariances and effective channels. We analyze what local CSI is required in the weighted minimization of the mean square error (WMMSE) algorithm for distributed coordinated precoding, and we study how this required CSI can be obtained in a distributed fashion. Based on pilot-assisted channel estimation, we propose three CSI acquisition methods with different tradeoffs between feedback and signaling, backhaul use, and computational complexity. One of the proposed methods is fully distributed, meaning that it only depends on over-the-air signaling but requires no backhaul, and it results in a fully distributed joint system when coupled with the WMMSE algorithm. Naïvely applying the WMMSE algorithm together with the fully distributed CSI acquisition results in catastrophic performance however; therefore, we propose a robustified WMMSE algorithm (RB-WMMSE) based on the well-known diagonal loading framework. By enforcing properties of the WMMSE solutions with perfect CSI onto the problem with imperfect CSI, the resulting diagonally loaded spatial filters are shown to perform significantly better than the naïve filters. The proposed robust and distributed system is evaluated using numerical simulations and is shown to perform well compared with benchmarks. Under centralized CSI acquisition, the proposed algorithm performs on par with other existing centralized robust WMMSE algorithms. When evaluated in a large-scale fading environment, the performance of the proposed system is promising

Regional chromosomal localization of N-<i>ras</i>, K-<i>ras</i>-1, K-<i>ras</i>-2 and<i>myb</i>oncogenes in human cells (1983)

The identification of transforming genes in human tumor cells has been made possible by DNA mediated gene transfer techniques. To date, it has been possible to show that most of these transforming genes are activated cellular analogues of the ras oncogene family. To better understand the relationship between these oncogenes and other human genes, we have determined their chromosomal localization by analyzing human rodent somatic cell hybrids with molecularly cloned human proto-oncogene probes. It was possible to assign N-ras to chromosome 1 and regionally localize c-K-ras-1 and c-K-ras-2 to human chromosomes 6pter-q13 and 12q, respectively. These results along with previous studies demonstrate the highly dispersed nature of ras genes in the human genome. Previous reports indicated that the c-myb gene also resides on chromosome 6. It has been possible to sublocalize c-myb to the long arm of chromosome 6 (q15-q21). The non-random aberrations in chromosomes 1, 6 and 12 that occur in certain human tumors suggest possible etiologic involvement of ras and/or myb oncogenes in such tumors.
Chiroptical Switches: Applications in Sensing and Catalysis (2012)

Chiroptical switches have found application in the detection of a multitude of different analytes with a high level of sensitivity and in asymmetric catalysis to offer switchable stereoselectivity. A wide range of scaffolds have been employed that respond to metals, small molecules, anions and other analytes. Not only have chiroptical systems been used to detect the presence of analytes, but also other properties such as oxidation state and other physical phenomena that influence helicity and conformation of molecules and materials. Moreover, the tunable responses of many such chiroptical switches enable them to be used in the controlled production of either enantiomer or diastereomer at will in many important organic reactions from a single chiral catalyst through selective use of a low-cost inducer: Co-catalysts (guests), metal ions, counter ions or anions, redox agents or electrochemical potential, solvents, mechanical forces, temperature or electromagnetic radiation.
Preparation and characterization of plasma‐polymerized <i>N</i>‐vinyl‐2‐pyrrolidone films (1989)

Abstract Thin films (< 1 μm) of plasma polymerized N ‐vinyl‐2‐pyrrolidone (PPNVP) have been prepared, using an inductively coupled RF glow discharge in a flow‐through reactor system. PPNVP films were hydrophilic, smooth, and appeared morphologically homogeneous. The polymer deposition rate was found to increase linearly with NVP flow rate, and to decrease with the distance from the induction coil. ATR–FT–IR spectral studies suggested a highly branched polymer structure and included absorptions at 2150 and 1540 cm −1 which were unique to the plasma polymer and derived from lactam ring opening/breaking reactions. ESCA studies demonstrated that, under a given set of plasma reaction conditions, the surface composition was consistent throughout the reactor. However, polymer composition was influenced by larger changes in the plasma energy, since the nitrogen content was found to decrease with increasing W/FM . This corresponded to concomitant increases in the advancing water contact angles and to small but reproducible changes in the IR spectrum.

Cloning of poly(3-hydroxybutyric acid) synthase genes of Rhodobacter sphaeroides and Rhodospirillum rubrum and heterologous expression in Alcaligenes eutrophus (1992)

From genomic libraries of the purple non-sulfur bacteria Rhodospirillum rubrum Ha and Rhodobacter sphaeroides ATCC 17023 in the broad-host range cosmid pVK100, we cloned a 15- and a 14-kbp HindIII restriction fragment, respectively. Each of these fragments restored the ability to accumulate poly(3-hydroxybutyrate) (PHB), in the PHB-negative mutant Alcaligenes eutrophus PHB-4. These hybrid cosmids also complemented PHB-negative mutants derived from wild-type R. rubrum or R. sphaeroides. Both fragments hybridized with the PHB synthase structural gene of A. eutrophus H16 and conferred the ability to express PHB synthase activity. Only the 15-kbp HindIII fragment from R. rubrum conferred on the mutant PHB-4 the ability to form large PHB granules (length up to 3.5 microns).
Synthesis of Dibenzo[<i>b</i>,<i>f</i>][1,4]oxazepin-11(10<i>H</i>)-ones via Intramolecular Cyclocarbonylation Reactions Using PdI<sub>2</sub>/Cytop 292 as the Catalytic System (2010)

The intramolecular cyclocarbonylation of substituted 2-(2-iodophenoxy)anilines was catalyzed by PdI(2) and 1,3,5,7-tetramethyl-6-phenyl-2,4,8-trioxa-6-phospha-adamantane (Cytop 292) in an efficient manner. A series of substituted dibenzo[b,f][1,4]oxazepin-11(10H)-ones were prepared in good yields under mild reaction conditions.
Reversible tetramerization of human TK1 to the high catalytic efficient form is induced by pyrophosphate, in addition to tripolyphosphates, or high enzyme concentration (2008)

Thymidine kinase (TK1) is a key enzyme in the salvage pathway of deoxyribonucleotide metabolism, catalyzing the first step in the synthesis of dTTP by transfer of a gamma-phosphate group from a nucleoside triphosphate to the 5'-hydroxyl group of thymidine, forming dTMP. Human TK1 is cytosolic and its activity is absent in resting cells, appears in late G(1), increases in S phase coinciding with the increase in DNA synthesis, and disappears during mitosis. The fluctuation of TK1 through the cell cycle is important in providing a balanced supply of dTTP for DNA replication, and is partly due to regulation of TK1 expression at the transcriptional level. However, TK1 is a regulatory enzyme that can interchange between its dimeric and tetrameric forms, which have low and high catalytic efficiencies, respectively, depending on pre-assay incubation with ATP. Here, the part of ATP that is necessary for tetramerization and how the reaction velocity is influenced by the enzyme concentration are determined. The results show that only two or three of the phosphate groups of ATP are necessary for tetramerization, and that kinetics and tetramerization are closely related. Furthermore, the enzyme concentration was found to have a pivotal effect on catalytic efficiency.
MHF treatment design-1: Tight sands require detailed planning (1983)

In recent years massive hydraulic fracturing (MHF) has become an important technique for the stimulation of low permeability hydrocarbon reservoirs. Since the financial considerations for MHF treatments are significant, treatments must be well planned to be cost-effective. This article will discuss, (1) MHF design parameters and considerations, (2) type of equipment required, (3) pre-job planning and logistics, and (4) the use of temperature and radioactive (RA) surveys, such that the ultimate goal (a costeffective MHF treatment) is achieved. The extremely high cost of MHF combined with the need to create deeply penetrating, highly conductive fractures under high overburden stresses, demand a high level of technology.
Dendrimers Made of Porphyrin Cores and Carbazole Chromophores as Peripheral Units. Absorption Spectra, Luminescence Properties, and Oxidation Behavior (2005)

Luminescent and redox-active porphyrin-based dendrimers of first and second generation have been synthesized, and their absorption spectra, photophysical properties, and oxidation behavior have been investigated, together with those of the corresponding aldehyde carbazole precursors. All the dendrimers contain a porphyrin core and carbazole-based chromophores as branches. The structural formulas of the new species are represented in Figures 1 and 2, with the corresponding schematizations. The absorption spectra of the aldehyde carbazole precursors A1-A6 in dichloromethane exhibit intense transitions in the UV region, centered on the carbazole and benzaldehyde subunits. The lowest-energy absorption bands receive contribution from charge-transfer transitions. Compounds A1-A6 are luminescent at room temperature in fluid solution; such a luminescence is attributed to twisted intramolecular charge-transfer excited states. The luminescence at 77 K in a rigid matrix is blue-shifted with respect to room-temperature emission and is assigned to locally excited states. Absorption spectra of the porphyrin-cored dendrimers P1-P6 appear additive as they are constituted by visible bands due to porphyrin absorption and bands in the UV region due to transitions centered on the carbazole-based branches. Emission spectra of P1-P6 both at 77 K and at room temperature are typical of porphyrin species and independent of excitation wavelength, indicating that the light collected by the peripheral chromophores is quantitatively transferred to the core. All the compounds exhibit a rich oxidation behavior in 1,2-dichloroethane solution, with reversible processes centered on the different carbazole subunits. Interaction between the different carbazole centers depends on the size of the spacer interposed.
Immunohistochemical detection of P-glycoprotein in endometrial adenocarcinoma. (1991)

P-glycoprotein (Pgp) has emerged as the central mediator in classic multidrug resistance in model systems in vitro. High levels of Pgp also have been detected in many normal human tissues and tumors; and its role in clinical drug resistance is currently under investigation. Recently significant levels of Pgp were localized to gravid and secretory endometrium; and it was demonstrated that the combination of estrogen and progesterone is sufficient to induce high levels of both Pgp mRNA and Pgp in uterine secretory epithelium. These findings suggest that increased Pgp expression also may be present in hormone-responsive malignancies such as endometrial adenocarcinoma. To determine whether Pgp is expressed in endometrial adenocarcinoma, 36 endometrial adenocarcinomas (grade I [n = 17]; grade II [n = 6]; grade III [n = 13]) were investigated retrospectively by the avidin-biotin-complex immunohistochemical procedure using three murine monoclonal antibodies (MAb) MAb C219, MAb C494, and MAb JSB-1, which recognize spatially distinct cytoplasmic epitopes of Pgp. Seventy-two percent of the tumors showed positive immunostaining with at least one MAb; 67% showed immunostaining with MAb C219, 50% with MAb C494, and 62% with MAb JSB-1. Forty-six percent of tumors were immunoreactive to two and 29% to all three antibodies. Membranous and Golgi/paranuclear type staining patterns were observed. Overall the intensity of immunostaining varied from one sample to another for a given tumor type, and considerable heterogeneity of expression was commonly seen within a given tumor. Strong to moderate immunoreactivity was seen in diffusely infiltrating, adenosquamous, and serous papillary carcinomas. In general, immunoreactivity to MAb C494 was weaker than MAb C219 or MAb JSB-1. Adenomatous and non-neoplastic endometrium adjacent to the tumors displayed strong membranous immunostaining with MAb JSB-1. Endometrial capillaries showed weak-to-moderate immunostaining to all three antibodies. It is concluded that Pgp is commonly expressed in endometrial adenocarcinoma and may be a significant factor responsible for their drug-resistant nature subject to modulation by progesterone.

Giant electrostrictive response of polymers (1993)

A new class of electroacoustic materials has been discovered at the Polymer Electroprocessing Laboratory, Rutgers University, based on the enormous electrostrictive response available in certain classes of polymeric materials. Further, many of the properties of these materials, including the dielectric constant and elastic modulus, can be tailored for specific end-use applications. The new material is ‘‘created’’ by applying a very large (≳10 MV/m), dc bias electric field using a superimposed ac driving signal to produce the required acoustic response. The measured thickness response dT, which is electrostrictive in nature, is proportional to the slope of the strain versus the applied electric field curve and is, therefore, proportional to the applied electric field up to saturation. Extremely high dT values (dT≳10 Å/V) can be accessed at high enough dc bias fields (≳20 MV/m).
Distinct roles of GSK-3α and GSK-3β phosphorylation in the heart under pressure overload (2008)

Glycogen synthase kinase-3 (GSK-3) is a master regulator of growth and death in cardiac myocytes. GSK-3 is inactivated by hypertrophic stimuli through phosphorylation-dependent and -independent mechanisms. Inactivation of GSK-3 removes the negative constraint of GSK-3 on hypertrophy, thereby stimulating cardiac hypertrophy. N-terminal phosphorylation of the GSK-3 isoforms GSK-3alpha and GSK-3beta by upstream kinases (e.g., Akt) is a major mechanism of GSK-3 inhibition. Nonetheless, its role in mediating cardiac hypertrophy and failure remains to be established. Here we evaluated the role of Serine(S)21 and S9 phosphorylation of GSK-3alpha and GSK-3beta in the regulation of cardiac hypertrophy and function during pressure overload (PO), using GSK-3alpha S21A knock-in (alphaKI) and GSK-3beta S9A knock-in (betaKI) mice. Although inhibition of S9 phosphorylation during PO in the betaKI mice attenuated hypertrophy and heart failure (HF), inhibition of S21 phosphorylation in the alphaKI mice unexpectedly promoted hypertrophy and HF. Inhibition of S21 phosphorylation in GSK-3alpha, but not of S9 phosphorylation in GSK-3beta, caused phosphorylation and down-regulation of G1-cyclins, due to preferential localization of GSK-3alpha in the nucleus, and suppressed E2F and markers of cell proliferation, including phosphorylated histone H3, under PO, thereby contributing to decreases in the total number of myocytes in the heart. Restoration of the E2F activity by injection of adenovirus harboring cyclin D1 with a nuclear localization signal attenuated HF under PO in the alphaKI mice. Collectively, our results reveal that whereas S9 phosphorylation of GSK-3beta mediates pathological hypertrophy, S21 phosphorylation of GSK-3alpha plays a compensatory role during PO, in part by alleviating the negative constraint on the cell cycle machinery in cardiac myocytes.
