A glass reflowed microlens array on a Si substrate with rectangular through-holes (2008)

A thermally reflowed glass microlens array was fabricated on a Si substrate. Glass lenses are more durable and scratch-resistant than plastic lenses made by the same, simple thermal reflow process. The microlens was designed using the ray tracing technique and optimized by controlling the nominal diameter and height of glass cylinders. The glass cylinders were formed by wet etching a glass plate in a HF (49%) solution and reflowed to form a semi-spherical lens shape at 850 °C (glass transition temperature Tg = 820 °C) for 20 min in a furnace. Then, the Si substrate was etched in a TMAH (5%) solution to make rectangular through-holes underneath the microlens array for high optical transmission. The profile of the fabricated microlens was measured with a confocal microscope, and its optical characteristics (lens size, beam radius and focal length) were evaluated with a 633 nm laser diode beam. The experimental beam waist (minimum beam radius) at the focal point of 1000 µm was 8 µm, which was in good agreement with a calculated value. The results show that the microlens array can be used in a broad wavelength range from UV to the IR region.

Effect of Hormones on Expression of Prolactin Receptor Messenger Ribonucleic Acids in Pancreatic Islets of Adult Female Mice<i>In Vitro</i> (1997)

We studied the effects of hormones on expression of prolactin receptor (PRL-R) mRNA in pancreatic islets of adult female mice in vitro. We quantified mRNA expression in small amounts of the islet tissue by competitive PCR and one-sided competitive PCR. Fifty pancreatic islets from adult female mice were cultured in a wall for 4 days with or without ovine prolactin (PRL), bovine growth hormone or estradiol-17 beta. PRL (1 microgram/ml) significantly increased the insulin secretion and the amount of PRL-R mRNA relative to that of beta-actin mRNA. Growth hormone (1 microgram/ml) also increased the relative amount of PRL-R mRNA, although it did not significantly increase the insulin secretion. Neither insulin secretion nor the relative amount of PRL-R mRNA was affected by estradiol (100 ng/ml). The ratio of the short form to the long form of PRL-R mRNA was not altered by these hormones. The present observation that PRL increased PRL-R mRNA expression in pancreatic islets thus suggests the possibility that PRL up-regulates the tissue sensitivity to PRL itself during lactation.
Fabrication of a DRA Array Using Ceramic Stereolithography (2006)

The purpose of this letter is to demonstrate monolithic fabrication of an array of dielectric resonator antennas (DRAs) using ceramic stereolithography. Design and measurements of a eight-by-eight array of rectangular DRAs composed of four monolithic four-by-four array blocks are presented. The array elements are designed over a ground plane and fed by a standard aperture-coupled microstrip corporate feed network. It is shown that the corporate feed, and not the DRAs, is mainly responsible for losses in the radiating structure
Molecular Mapping of QTLs Conferring Fusarium Head Blight Resistance in Chinese Wheat Cultivar Jingzhou 66 (2020)

Fusarium head blight (FHB) is a destructive disease of wheat (<i>Triticum aestivum</i> L.), which not only significantly reduces grain yield, but also affects end-use quality. Breeding wheat cultivars with high FHB resistance is the most effective way to control the disease. The Chinese wheat cultivar Jingzhou 66 (JZ66) shows moderately high FHB resistance; however, the genetic basis of its resistance is unknown. A doubled haploid (DH) population consisting 209 lines was developed from a cross of JZ66 and Aikang 58 (AK58), a FHB susceptible wheat cultivar, to identify quantitative trait loci (QTL) that contribute to the FHB resistance. Five field experiments were established across two consecutive crop seasons (2018 and 2019) to evaluate the DH lines and parents for FHB response. The parents and DH population were genotyped with the wheat 55K single-nucleotide polymorphism (SNP) assay. Six QTLs associated with FHB resistance in JZ66 were mapped on chromosome 2DS, 3AS, 3AL, 3DL, 4DS, and 5DL, respectively. Four of the QTL (<i>QFhb.hbaas-2DS</i>, <i>QFhb.hbaas-3AL</i>, <i>QFhb.hbaas-4DS</i>, and <i>QFhb.hbaas-5DL</i>) were detected in at least two environments, and the QTL on 3AL and 5DL might be new. The QTL with major effects, <i>QFhb.hbaas-2DS</i> and <i>QFhb.hbaas-4DS</i>, explained up to 36.2% and 17.6% of the phenotypic variance, and were co-localized with the plant semi-dwarfing loci <i>Rht8</i> and <i>Rht-D1.</i> The dwarfing <i>Rht8</i> allele significantly increased spike compactness (SC) and FHB susceptibility causing a larger effect on FHB response than <i>Rht-D1</i> observed in this study. PCR-based SNP markers for <i>QFhb.hbaas-2DS</i>, <i>QFhb.hbaas-3AL</i>, <i>QFhb.hbaas-4DS</i>, and <i>QFhb.hbaas-5DL</i>, were developed to facilitate their use in breeding for FHB resistance by marker-assisted selection.
Erasure Coding with the Finite Radon Transform (2010)

The Mojette transform and the finite Radon transform (FRT) are discrete data projection methods that are exactly invertible and are computed using simple addition operations. Incorporation of a known level of redundancy into data and projection spaces enables the use of the FRT to recover the exact, original data when network packets are lost during data transmission. The FRT can also be shown to be Maximum Distance Separable (MDS). By writing the FRT transform in Vandermonde form, explicit expressions for discrete projection and inversion as matrix operations have been obtained. A cyclic, prime-sized Vandermonde form for the FRT approach is shown here to yield explicit polynomial expressions for the recovery of image rows from projected data and vice-versa. These polynomial solutions are consistent with the heuristic algorithms for "row-solving" that have been published previously. This formalism also opens the way to link "ghost" projections in FRT space and "anti-images" in data space that may provide a key to an efficient method of encoding and decoding general data sets in a systematic form.
Exploiting positive equality and partial non-consistency in the formal verification of pipelined microprocessors (1999)

We study the applicability of the logic of Positive Equality with Uninterpreted Functions (PEUF) [2][3] to the verification of pipelined microprocessors with very large Instruction Set Architectures (ISAs). Abstraction of memory arrays and functional units is employed, while the control logic of the processors is kept intact from the original gate-level designs. PEUF is an extension of the logic of Equality with Uninterpreted Functions, introduced by Burch and Dill We present several techniques that make PEUF scale very efficiently for the verification of pipelined microprocessors with large ISAs. These techniques are based on allowing a limited form of non-consistency in the uninterpreted functions, representing initial memory state and ALU behaviors. Our tool required less than 30 seconds of CPU time and 5 MB of memory to verify a 5-stage MIPS-like pipelined processor that implements 191 instructions of various classes. The verification was done by correspondence checking -a formal method, where a pipelined microprocessor is compared against a non-pipelined specification.
The role of microRNAs in cancer. (2006)

Cancer is a complex and dynamic disease, involving a variety of changes in gene expression and structure. Traditionally, the study of cancer has focused on protein-coding genes, considering these as the principal effectors and regulators of tumorigenesis. Recent advances, however, have brought non-protein-coding RNA into the spotlight. MicroRNAs (miRNAs), one such class of non-coding RNAs, have been implicated in the regulation of cell growth, differentiation, and apoptosis [1]. While their study is still at an early stage, and their mechanism of action along with their importance in cancer is not yet fully understood, they may provide an important layer of genetic regulation in tumorigenesis, and ultimately become valuable therapeutic tools.
Elastic Vibration Characteristics of Cantilever Plates in Water (1965)

An experimental study of the vibrations of cantilever plates in air and in water has been conducted, and the results are compared with theoretical predictions based on simple beam theory and thin-plate theory. Both theories are modified to include an apparent mass factor which is derived from chordwise hydrodynamic strip theory. Good theoretical and experimental correlation is achieved upon further including an empirical correction factor which allows for the influence of plate aspect ratio and thickness ratio on the results. Liquid free surface and partial submergence effects are determined experimentally.
High power femtosecond source near 1 micron based on an all-fiber Er-doped mode-locked laser (2010)

We report the design and performance of a high power femtosecond laser source near 1 micron wavelength which is generated from an octave-spanning supercontinuum (SC) pumped by an Er-doped mode-locked laser. The laser system delivers >5W average power at 35MHz repetition rate and 135 fs pulse duration.
PKC and PKA Phosphorylation Affect the Subcellular Localization of Claudin-1 in Melanoma Cells (2009)

Cytoplasmic expression of claudin-1 in metastatic melanoma cells correlates to increased migration, and increased secretion of MMP-2 in a PKC dependent manner, whereas claudin-1 nuclear expression is found in benign nevi. Melanoma cells were transfected with a vector expressing CLDN-1 fused to a nuclear localization signal (NLS). Despite significant nuclear localization of claudin-1, there was still transport of claudin-1 to the cytoplasm. Phorbol ester treatment of cells transfected with NLS-claudin-1 resulted in an exclusion of claudin-1 from the nucleus, despite the NLS. To ascertain whether PKC or PKA were involved in this translocation, we mutated the putative phosphorylation sites within the protein. We found that mutating the PKC phosphorylation sites to mimic a non-phosphorylated state did not cause a shift of claudin-1 to the nucleus of the cells, but mutating the PKA sites did. Mutations of either site to mimic constitutive phosphorylation resulted in cytoplasmic claudin-1 expression. Stable claudin-1 transfectants containing non-phosphorylatable PKA sites exhibited decreased motility. These data imply that subcellular localization of claudin-1 can be controlled by phosphorylation, dicating effects on metastatic capacity.
Stimulation of Src Family Protein-tyrosine Kinases as a Proximal and Mandatory Step for SYK Kinase-dependent Phospholipase Cγ2 Activation in Lymphoma B Cells Exposed to Low Energy Electromagnetic Fields (1998)

Here, we present evidence that exposure of DT40 lymphoma B cells to low energy electromagnetic field (EMF) results in a tyrosine kinase-dependent activation of phospholipase Cgamma2 (PLC-gamma2) leading to increased inositol phospholipid turnover. B cells rendered PLC-gamma2-deficient by targeted disruption of the PLC-gamma2 gene as well as PLC-gamma2-deficient cells reconstituted with Src homology domain 2 (SH2) domain mutant PLC-gamma2 did not show any increase in inositol-1,4,5-trisphosphate levels after EMF exposure, providing direct evidence that PLC-gamma2 is responsible for EMF-induced stimulation of inositol phospholipid turnover, and its SH2 domains are essential for this function. B cells rendered SYK-deficient by targeted disruption of the syk gene did not show PLC-gamma2 activation in response to EMF exposure. The C-terminal SH2 domain of SYK kinase is essential for its ability to activate PLC-gamma2. SYK-deficient cells reconstituted with a C-terminal SH2 domain mutant syk gene failed to elicit increased inositol phospholipid turnover after EMF exposure, whereas SYK-deficient cells reconstituted with an N-terminal SH2 domain mutant syk gene showed a normal EMF response. LYN kinase is essential for the initiation of this biochemical signaling cascade. Lymphoma B cells rendered LYN-deficient through targeted disruption of the lyn gene did not elicit enhanced inositol phospholipid turnover after EMF exposure. Introduction of the wild-type (but not a kinase domain mutant) mouse fyn gene into LYN-deficient B cells restored their EMF responsiveness. B cells reconstituted with a SH2 domain mutant fyn gene showed a normal EMF response, whereas no increase in inositol phospholipid turnover in response to EMF was noticed in LYN-deficient cells reconstituted with a SH3 domain mutant fyn gene. Taken together, these results indicate that EMF-induced PLC-gamma2 activation is mediated by LYN-regulated stimulation of SYK, which acts downstream of LYN kinase and upstream of PLC-gamma2.
The complele DNA sequence and regulatory regions of the<i>Bacillus licheniformis spoOH</i>gene (1984)

We have determined the sequence of a 1228 base-pair cloned DNA fragment from Bacillus licheniformis capable of specifically complementing mutations in the spoOH gene, which is required for the early stage of sporulation in B. subtilis. The sequence has only one long open reading frame consisting of 168 codons. In vivo and in vitro transcription mapping studies indicate the size of complementary RNA to be around 1 kb with the 5' initiation site at base 79 and the 3' termination site in the area of base 1138. This indicates the presence of a 5' untranslated RNA and a fairly long 3' extension. The promoter sequence of this gene is 5'TATAAT3' at -10, and 5'TTGACG3' at -35, a typical E. coli-like promoter sequence, and is transcribed in vitro specifically only by RNA polymerase containing delta 55 and not delta 37-containing holoenzyme.
Share it! - content transfer in home-to-home networks (2004)

This paper presents a possible solution for the introduction of a complementary distribution chain into the broadcast environment. In the described scenario, personal video recorders with local storage are networked into an ad-hoc home-to-home network based on an emerging peer-to-peer protocol that enables broadcast as well as home-produced content sharing. The paper presents the current system architecture as conceived within a consortium working on the Share it! project.
ENHANCED PROTEIN LOADING INTO LIPOSOMES BY THE MULTIPLE CROSSFLOW INJECTION TECHNIQUE (2002)

Methods for encapsulation of a drug into liposomes should preferably result in a high encapsulation efficiency and a high encapsulation capacity. Our studies were focussed on the establishment of an efficient encapsulation procedure of the radical scavenging protein, rh-Cu/Zn-SOD, into liposomes with the cross flow injection method. Limitations to increase the encapsulation efficiency are caused by the enclosed aqueous volume, by the lipid concentration, the aspired vesicle size and the final ethanol concentration. Our research was performed to maximize the encapsulation following several strategies of injecting higher lipid concentrations into the aqueous phase. The one way triple technique, a sophisticated preparation procedure is presented, which enables three times higher encapsulation rates in comparison to standard procedures. Additionally, scalability studies demonstrate reproducibility independent of the preparation volume. Vesicle size distribution and encapsulation efficiency remain constant. Furthermore, special attention is paid on reproducibility of prepared liposomes, scale-up and on long term stability of the lipid vesicles.
Efficient parametric generation of high-power coherent picosecond pulses in lithium borate tunable from 0.405 to 2.4 μm (1992)

We have used lithium borate crystals, pumped by 18 ps laser pulses at 0.355 μm, as efficient optical parametric generator and amplifier of tunable, high-power picosecond pulses in the visible and near-infrared. This angle-tuned parametric device has a remarkably wide tuning range from 0.403 to 2.58 μm with a maximum pump-to-signal conversion of 28% around 0.425 μm. We investigate the influence of the pump intensity on the bandwidth of the tunable output. The duration of signal and idler pulses is 11–12 ps. No bulk or surface damage was observed for pump intensities up to 5 GW/cm2.
Hindered Ureas as Masked Isocyanates: Facile Carbamoylation of Nucleophiles under Neutral Conditions (2009)

Bigger is better: Sterically hindered dialkyl ureas undergo nucleophilic substitution at dramatically faster rates than their less hindered counterparts (see scheme). Steric decompression upon the formation of an intermediate isocyanate can explain this counterintuitive behavior. These hindered ureas can be considered as masked reagents that liberate reactive isocyanates in situ. Detailed facts of importance to specialist readers are published as ”Supporting Information”.

Understanding Elemental Reactions at Electrode | Electrolyte Interface in Rechargeable Li Ion Battery by Using Electrochemical AC Impedance Spectroscopy (2012)

AC impedance spectroscopy is a powerful and convenient technique to investigate the elemental reaction at electrode | electrolyte interface in rechargeable lithium ion battery. This paper describes fitting procedure of impedance plots and assignment of each separated resistance to elemental reaction. In particular, the elemental reaction occurred at A-site deficient perovskite, La1/3NbO3, electrode is focused in this paper, since no significant side-reaction was observed due to mild voltage range from 2 to 1 V vs. Li+/Li. The results indicated two elemental reactions at the interface of electrode | electrolyte corresponding to higher and lower frequency region in AC impedance spectra, and attempts has been made to be described in terms of an ‘adatom model’.
Electromechanical Probing of Li/Li<sub>2</sub>CO<sub>3</sub>Core/Shell Particles in a TEM (2013)

We provide a detailed electromechanical study of individual core/shell structure – Li metal/Li2CO3 particles by utilizing an in-situ probing technique in the transmission electron microscope (TEM). This technique allows us to concurrently monitor the mechanical and electrical response of single Li/Li2CO3 core/shell structures in real time. The pressure on the Li/Li2CO3 core/shell particle was measured to be ∼15 MPa at the initiation of fracture and the conductivity of the Li2CO3 shell is estimated to be ∼10−6 S/cm. To simulate the application of the core-shell particles in a real battery, we assembled coin cells with Li metal as a counter electrode. Prior to the cell assembly, the electrode was compressed in order to break the Li2CO3 shells to expose the fresh lithium metal to the graphite. When the electrolyte is added to wet the electrode, an electrochemical reaction spontaneously occurs between the exposed Li and graphite particles to produce a partially lithiated graphite anode. This lithiation occurs prior to the initial charging process, therefore compensating for the irreversible capacity loss due to the lithium consummation events during standard formation.1–3 Our results demonstrate a new pathway for the utilization of non-lithiated cathode material in future Li-ion batteries.
Die <i>liter&#234;r-historiese</i> lees van 'n teks (1999)

The discussion on methodology in the South African exegetical and hermeneutical debate has not been completed yet. Several contributions during the past six years have kept this debate alive. Nevertheless, the duration of the discussion has brought growth and more understanding for different viewpoints and approaches. The aim of this article is to argue that both literary and historical aspects in the reading of any Old Testament text are important. Although it is not the only text approach, it proposes the literary-historical reading of texts is a comprehensive way to expose and understand Biblical texts.
Excitatory Amino Acids in the Rostral Ventrolateral Medulla Support Blood Pressure in Spontaneously Hypertensive Rats (2000)

Injection of the excitatory amino acid (EAA) antagonist kynurenic acid (KYN) into the rostral ventrolateral medulla (RVLM) of anesthetized rats has no effect on arterial pressure. However, we recently reported that after inhibition of the caudal ventrolateral medulla, injection of KYN into the RVLM decreased arterial pressure to the same level as produced by complete inhibition of the RVLM. We have suggested that these results reflect tonically active EAA-mediated inputs to the RVLM producing both direct excitation of RVLM vasomotor neurons and indirect inhibition of these neurons. On the basis of this model, we hypothesize that the balance between these EAA-driven direct excitatory and indirect inhibitory influences on the RVLM may be altered in models of experimental hypertension. To begin to test this hypothesis, the effects of injecting KYN into the RVLM of spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY) were compared. In chloralose-anesthetized WKY, bilateral injection of KYN into the RVLM did not alter arterial pressure, whereas similar injections in SHR reduced mean arterial pressure by approximately 40 mm Hg. After inhibition of the caudal ventrolateral medulla, which similarly increased arterial pressure in both strains, injection of KYN into the RVLM reduced mean arterial pressure to the same level as produced by autonomic blockade. These results suggest that the balance of excitatory and inhibitory influences on RVLM vasomotor neurons driven by tonically active EAA-mediated inputs to the RVLM is disrupted in SHR and may contribute to the hypertension in SHR.
