Can a nonradiating mode be externally excited? Nonscattering states vs.\n embedded eigenstates (2019)

In this Letter, we discuss the general problem of exciting radiationless\nfield distributions in open cavities, with the goal of clarifying recent\nfindings on this topic. We point out that the radiationless scattering states,\nlike anapoles, considered in several recent studies, are not eigenmodes of an\nopen cavity; therefore, their external excitation is neither surprising nor\nchallenging (similar to the excitation of nonzero internal fields in a\ntransparent, or cloaked, object). Even more, the radiationless anapole field\ndistribution cannot be sustained without the actual presence of external\nincident fields. Conversely, we prove that the Lorentz reciprocity theorem\nprevents the external excitation of radiationless optical eigenmodes, as in the\ncase of embedded eigenstates and bound states in the continuum in open\ncavities. Our discussion clarifies the analogies and differences between\ninvisible bodies, nonradiating sources, anapole scatterers and emitters, and\nembedded eigenstates, especially in relation to their external excitation.\n
Solid products from thermal decomposition of polyethylene terephthalate: Investigation by CP/MAS <sup>13</sup>C‐NMR and fourier transform‐IR spectroscopy (1984)

Abstract The solid reaction products from pyrolysis of polyethylene terephthalate in the presence and absence of red phosphorus were characterized by CP/MAS 13 C‐NMR, FR‐IR, and MAS 31 P‐NMR spectroscopy. Over the temperature range of 300–400°C, polyethylene terephthalate was converted in a sealed vial to a highly crosslinked polymer of terephthalic acid. Pyrolysis in the presence of red phosphorus, which functions as a flame retardant by increasing the amount of char, yielded an intractible polyaromatic phosphate ester. After thermal cleavage of polyethylene terephthalate with formation of free carboxyl and vinyl ester groups, there are two competing reaction pathways. The smaller molecular weight fragments may enter the vapor phase where they undergo further degradation primarily to CO 2 , CO, and acetaldehyde, as described by others. However, if volatilization of the oligomeric fragments is inhibited, an alternate reaction pathway gives rise to the formation of highly crosslinked char. Red phosphorus decreases the volatility of the oligomeric fragments by converting them to phosphates and thereby enhances char formation.
Optical Sensing of Small Hydroxyl-Containing Molecules in New Crystalline Lamellar Arrays of Co(II) and <i>N</i>-(4-Pyridyl)benzamide (2002)

We report the preparation, structure, and function of a supramolecular assembly that exhibits chemoselective optical sensing properties toward small hydroxyl-containing molecules. The active structure is generated by thermal desolvation of Co(NPBA)2(H2O)2(NO3)2 (1), NPBA = N-(4-pyridyl)benzamide, and the generated structure 2 can optically detect methanol, ethanol, n-propanol, or phenol in dichloromenthane at sub-millimolar concentrations.
Über polymere koronanden auf der basis von 18‐krone‐6 enthaltenden vinylmonomeren (1981)

Abstract Vinyl group containing derivatives of 18‐crown‐6 were synthesized and copolymerized with styrene and p ‐divinylbenzene of p ‐divinylbiphenyl. The selectivity of the alkali metal cation complexation of one of the polymers was investigated. The prepared polymers were applied as catalysts in several nucleophilic substitution reactions. The influence of the crosslinking agent as well as the degree of crosslinking on the catalytic activity of the polymers was studied.

β‐catenin mutation in ovarian solid pseudopapillary neoplasm (2014)

Primaly solid pseudopapillary neoplasm (SPN) of the ovary is a rare tumor; recently 6 cases have been reported. Its pathogenesis, however, remains largely unclear. We report an additional case of primary ovarian SPN of an 18-year-old girl. The aim of this study is to define the difference between pancreatic and ovarian SPN by histological and molecular examination. Microscopically the tumor predominantly showed a solid pattern and focally a pseudopapillary pattern. The tumor cells showed two patterns of abundant eosinophilic cytoplasm and intracytoplasmic vacuoles. Immunohistochemistry of the tumor was positive for β-catenin (nuclear and cytoplasmic reactivity), α1-antitrypsin, vimentin, CD56, synaptophysin (focal weak), CD10. Mutation analyses revealed a point mutation, c.110C >T, in exon 3 of the the β-catenin gene (CTNNB1), which causes the replacement of serine with phenylalanine at codon 37. A Ser37 point mutation is known to be one of the oncogenic somatic mutations in pancreatic SPN and the major oncogenic β-catenin mutation. Ovarian SPN of our case was similar to pancreatic SPN histologicaly and had the same genomic characteristics. We expected that both ovarian and pancreatic SPNs shared the same oncogenesis related to Wnt/β-catenin pathway for tumorgenesis.
A Unique Asymmetric [Mn] Triple-Stranded Helicate from a Symmetric Pentadentate Ligand (2001)

A new topology within the family of metallohelicates has been revealed by the crystal structure of the complex [Mn3(HL)3] (see picture). The novel oxygen-based pentadentate ligand H3L reacts with Mn(OAc)2 to produce this unique triple-stranded helicate with an unprecedented asymmetric arrangement of the metal ions along the molecular axis. This helicate displays intramolecular magnetic coupling.

Technical Note: Development of Water Usage Coefficients for a Fully Watered Tallgrass Prairie (2008)

An irrigation study was conducted from 1991 to 2000 at the Konza Prairie Biological Station (KPBS) Long-Term Ecological Research (LTER) site, near Manhattan, Kansas, to provide a better understanding of how the prairie ecosystem uses and dispenses water over the growing season. The irrigation transect was established on an annually burned portion of the 3,500 ha preserve of native tallgrass prairie in 1991. Irrigation transects created a water gradient over the topographically distinct upland and lowland areas of the experimental site. In order to calculate the plant water coefficient (crop coefficient) for the prairie ecosystem, the site was instrumented to measure soil moisture in 1994, and a water balance was performed at the fully watered locations on the irrigation transect to calculate actual evapotranspiration (ETc). These values, along with reference evapotranspiration (ETr) data calculated using the modified Penman equation, were used to determine the plant water usage coefficient based on the following relationship: ETc = ETr Kc Ksm, where Kc is the plant water usage coefficient, and Ksm is the soil moisture coefficient. For fully watered sites, the plant water usage coefficient is the ratio of ETc/ETr, since Ksm = 1.0 because of ample water. Results indicated maximum plant water usage coefficients of 1.32 in the fully watered locations, similar in magnitude to the crop coefficients of warm-season agricultural crops (ETr is alfalfa based). Over the season (June 1 to September 30), tallgrass water usage was below the reference crop water use, with an average growing season coefficient of 0.90.
RSFQ circular shift registers (1997)

The circular shift register is a versatile building block for RSFQ digital circuits. It can be used for local memory and it is essential for the proposed implementation of residue number system arithmetic. It is surprising that the successful recurrent operation of such a shift register has never been reported m the RSFQ literature. Circular shift registers have a design constraint that is unusual in RSFQ circuits-the requirement of zero overall clock skew. We propose and analyze three novel designs and compare their simulated parameter margins as well as their maximum operating frequencies, latencies and areas. These designs differ in the topology of the clock distribution network as well as the type of storage element employed in the data path. Two designs show satisfactory parameter margins and large maximum clock frequency.
Determination of cell division axes in the early embryogenesis of Caenorhabditis elegans. (1987)

The establishment of cell division axes was examined in the early embryonic divisions of Caenorhabditis elegans. It has been shown previously that there are two different patterns of cleavage during early embryogenesis. In one set of cells, which undergo predominantly determinative divisions, the division axes are established successively in the same orientation, while division axes in the other set, which divide mainly proliferatively, have an orthogonal pattern of division. We have investigated the establishment of these axes by following the movement of the centrosomes. Centrosome separation follows a reproducible pattern in all cells, and this pattern by itself results in an orthogonal pattern of cleavage. In those cells that divide on the same axis, there is an additional directed rotation of pairs of centrosomes together with the nucleus through well-defined angles. Intact microtubules are required for rotation; rotation is prevented by inhibitors of polymerization and depolymerization of microtubules. We have examined the distribution of microtubules in fixed embryos during rotation. From these and other data we infer that microtubules running from the centrosome to the cortex have a central role in aligning the centrosome-nuclear complex.
IRF5 deficiency severely impairs the development of T helper 1 responses following Leishmania donovani infection. (37.3) (2010)

Abstract The transcription factor Interferon Regulatory Factor 5 (IRF5) has been shown to be involved in the induction of proinflammatory cytokines in response to viral infections and TLR activation and to play an essential role in the innate inflammatory response. In this study, the experimental model of visceral leishmaniasis was used to investigate the role of IRF5 in the generation of Th1 responses and subsequent formation of Th1-type liver granulomas in Leishmania donovani infected mice. Here we show that IRF5 deficiency severely impairs the development of Th1 responses to L.donovani leading to the formation of Th2-type-like granulomas. These granulomas are characterized by a strong IL-4 response, upregulation of arginase 1 and Fizz1 mRNA and concomitant low iNOS expression. This study identifies IRF5 as a critical molecular switch for the development of Th1 immune responses following L.donovani infections and as an important molecule in the regulation of arginase 1 and iNOS expression.
The permanent electric dipole moments of the B 2Σ+ and X 2Σ+ states of lanthanum imide, LaNH (2003)

The optical Stark effect has been measured for the B̃ 2Σ+−X̃ 2Σ+, 301, and 201(P′=3/2) bands of lanthanum imide, LaNH, prepared in a supersonic molecular beam. The permanent electric dipole moment, μ, for the X̃ 2Σ+ state was determined to be 2.53±0.06 D from measurements of the second-order Stark shifts in the B̃ 2Σ+−X̃ 2Σ+, 301 band. (ν3 is the La–N stretching vibration, of symmetry σ+.) The dipole moment in the B̃ 2Σ+ state is too small to be determined from the Stark shifts in this band, but could be determined from the first-order Stark splittings in the P′=3/2 component of the B̃ 2Σ+, 21 bending fundamental (of upper state π symmetry); it was found to be 0.3±0.2 D. A comparison is made with LaO and other isovalent molecules involving Group IIIA atoms.
Printed Dipole Antenna for Use in Wireless Networks: Techniques for the Design Improvement (2005)

In this paper, new methods are proposed to reduce the size of a popularly used printed microstrip dipole antenna by 60%. Most antenna parameters such as efficiency, gain, and radiation pattern are unaffected by the size reduction. The key undesired consequence of the miniaturization process is the decrease in bandwidth. This paper demonstrates that the lost bandwidth can be recovered by some simple design techniques. To test the functionality of the miniaturized dipole antenna, it is integrated with a Zigbee wireless transceiver on the same PCB.
Abstract 2214: GITR ligand fusion protein (GITRL-Fc) induces T cell mediated anti-tumor immune response and can combine with anti-PDL1 to enhance anti-tumor immunity and long-term immune memory (2016)

Abstract GITRL (Glucocorticoid-Induced Tumor Necrosis Factor Receptor Ligand, TNFSF18) is a member of the TNF superfamily and naturally exists as a membrane-anchored type II protein that self assembles as a trimer. GITRL activates the co-stimulatory receptor GITR. GITR is found primarily on activated T effector (Teff) cells and regulatory T (Treg) cells. Co-stimulation of GITR by agonist agents is hypothesized to promote anti-tumor immunity by enhancing Teff cell activity and inhibiting Treg suppression. We generated a novel single-gene GITRL trimer fused to an immunoglobulin Fc domain (GITRL-Fc). GITRL-Fc activated GITR signaling more effectively than prototype GITR agonist antibody DTA-1. GITRL-Fc promoted a robust anti-tumor immune response in multiple syngeneic mouse tumor models. GITRL-Fc enhanced tumor specific T-cell responses, particularly of the Th1 type, and also led to reduction in Treg-mediated immunesuppressive activity. GITRL-Fc displayed single agent activity in inhibiting tumor growth and promoting complete tumor rejection in the murine CT26 colon carcinoma model and combination activity with anti-PDL1 as compared to anti-PDL1 and control IgG2a alone. Mice “cured” with GITRL or GITRL/anti-PDL1 combination treatments were protected from re-challenge with tumor cells, suggesting the existence of immunologic memory. More mice were protected from tumor re-challenge with the combination of GITRL-Fc and anti-PDL1, as compared to GITRL-Fc alone. Our results demonstrate that agonist GITRL-Fc induces potent T cell responses, overcomes Treg inhibition, and promotes anti-tumor activity in preclinical models as a single agent or in combination with anti PDL1. The mechanism of tumor eradication and induction of long-term immune memory response by the combination is under investigation and will be discussed at the presentation. Citation Format: Minu K.

Differential expression of matrix metalloproteinases and their inhibitors in non-small cell lung cancer (2000)

In a comprehensive immunohistochemical study of the expression of ten metalloproteinases (MMPs) and their four inhibitors (TIMPs) in 115 non-small cell lung carcinomas (NSCLCs), the findings have been correlated with the histological and clinical features of the tumours. All MMPs and TIMPs were expressed in tumours, with frequencies ranging from 41% for MMP-2 to 68% for MMP-13. Stromal immunoreactivity ranged from 6% for TIMP-4 to 87% for MMP-13. In some tumours, an overexpression of these proteins, as revealed by stronger staining in cancer cells than in adjacent normal bronchial epithelium, was also observed. The frequency ranged from 1% for MMP-3 to 28% for MMP-13. Compared with squamous cell carcinoma (SqCC), adenocarcinoma (AdC) more frequently overexpressed MMP-1, -11, -13, -14, and TIMP-2, and TIMP-1 and/or TIMP-2 overexpression positively correlated with more advanced stage disease. None of the MMP or TIMP expression correlated with the ras genotype of the tumours. The higher frequency of MMP overexpression in AdC than in SqCC may relate to the greater tendency of the former for systemic metastasis. The association of TIMP-1 overexpression with more advanced disease may suggest a role in prognosis.

Sensor‐based assessment of herbicide effects (2014)

Summary Non‐destructive assessment of herbicide effects may be able to support integrated weed management. To test whether effects of herbicides on canopy variables could be detected by sensors, two crops were used as models and treated with herbicides at BBCH 20 using a logarithmic sprayer. Twelve days after spraying at BBCH 25 and 42 days after sowing, nine sensor systems scanned a spring barley and an oilseed rape field experiment sown at different densities and sprayed with increasing field rates of glyphosate and tribenuron‐methyl. The objective was to compare ED 50 s for crops and weeds derived by the different sensors in relation to crop density and herbicides. Although sensors were not directly developed to detect herbicide symptoms, they all detected changes in canopy colours or height and crop density. Generally ED 50 s showed the same pattern in response to crop density within herbicide, but there were marked differences between barley and oilseed rape. We suggest that the results of comparing the various sensor outputs could become a stepping stone to future standardisation for the benefit of the research and development of sensors that will detect herbicide effect on crops and weeds, particularly at the most vulnerable stages of development of the canopy.

Effects of age-dependent changes in cell size on endothelial cell proliferation and senescence through YAP1 (2019)

Angiogenesis - the growth of new blood capillaries- is impaired in aging animals. Biophysical factors such as changes in cell size control endothelial cell (EC) proliferation and differentiation. However, the effects of aging on EC size and the mechanism by which changes in cell size control age-dependent decline in EC proliferation are largely unknown. Here, we have demonstrated that aged ECs are larger than young ECs and that age-dependent increases in EC size control EC proliferation and senescence through CDC42-Yes-associated protein (YAP1) signaling. Reduction of aged EC size by culturing on single-cell sized fibronectin-coated smaller islands decreases CDC42 activity, stimulates YAP1 nuclear translocation and attenuates EC senescence. Stimulation of YAP1 or inhibition of CDC42 activity in aged ECs also restores blood vessel formation. Age-dependent changes in EC size and/or CDC42 and YAP1 activity may be the key control point of age-related decline in angiogenesis.

Chemically Orthogonal Three‐Patch Microparticles (2014)

Compared to two-dimensional substrates, only a few methodologies exist for the spatially controlled decoration of three-dimensional objects, such as microparticles. Combining electrohydrodynamic co-jetting with synthetic polymer chemistry, we were able to create two- and three-patch microparticles displaying chemically orthogonal anchor groups on three distinct surface patches of the same particle. This approach takes advantage of a combination of novel chemically orthogonal polylactide-based polymers and their processing by electrohydrodynamic co-jetting to yield unprecedented multifunctional microparticles. Several micropatterned particles were fabricated displaying orthogonal click functionalities. Specifically, we demonstrate novel two- and three-patch particles. Multi-patch particles are highly sought after for their potential to present multiple distinct ligands in a directional manner. This work clearly establishes a viable route towards orthogonal reaction strategies on multivalent micropatterned particles.
