Expression of Serratia marcescens extracellular proteins requires recA (1990)

A previously described regulatory mutation which abolishes expression of the extracellular nuclease of Serratia marcescens is shown to be a mutation of the Serratia recA gene. The defect in nuclease expression could be restored by introducing a plasmid carrying the recA gene of Escherichia coli. The DNA sequence of the Serratia gene is very similar to that of the E. coli gene. The putative LexA-binding site of the Serratia recA gene is almost identical to that of E. coli, along with the promoter. A similar LexA-binding site can also be found upstream of the nuclease gene. As expected from this finding, we show that nuclease expression can be induced by SOS-inducing agents such as mitomycin C. Although inducible in S. marcescens, the nuclease was expressed only at the uninduced levels in E. coli and could not be induced by mitomycin C. The extracellular chitinase and lipase were similarly affected by the mutations altering nuclease expression and were also induced by mitomycin C.
Creating nanoscale emulsions using condensation (2017)

Nanoscale emulsions are essential components in numerous products, ranging from processed foods to novel drug delivery systems. Existing emulsification methods rely either on the breakup of larger droplets or solvent exchange/inversion. Here we report a simple, scalable method of creating nanoscale water-in-oil emulsions by condensing water vapor onto a subcooled oil-surfactant solution. Our technique enables a bottom-up approach to forming small-scale emulsions. Nanoscale water droplets nucleate at the oil/air interface and spontaneously disperse within the oil, due to the spreading dynamics of oil on water. Oil-soluble surfactants stabilize the resulting emulsions. We find that the oil-surfactant concentration controls the spreading behavior of oil on water, as well as the peak size, polydispersity, and stability of the resulting emulsions. Using condensation, we form emulsions with peak radii around 100 nm and polydispersities around 10%. This emulsion formation technique may open different routes to creating emulsions, colloidal systems, and emulsion-based materials.
Reducing Meat Perishability through Pullulan Active Packaging (2020)

The provision of safe products from the meat industry has been considered as the major source of protein for maintaining human health. Meat-borne outbreaks are mainly due to Salmonella typhimurium (S. typhimurium), Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), and Clostridium perfringens (C. perfringens), reducing the shelf life and consumer demands. A variety of vulnerable substances, including cholesterol oxidation products (COPs), are generated by the oxidation of meat induced by the microbial infestations. The use of certain biodegradable active packaging, including pullulan active packaging, is being focused by the meat industry due to their safety, stability, and negligible health risks. The potential of pullulan active packaging, incorporated with silver nanoparticles and essential oils, against E. coli, S. typhimurium, Mycoplasma, and other bacterial species is exclusive. Similarly, maintenance of organoleptic properties of meat with nominal oxidative rancidity and limited human health issues can be acquired by pullulan active packaging.
Relocation of the Bending Axis During Flexion-Extension of Lumbar Intervertebral Discs and its Implications for Prolapse (1983)

All the lumbar discs were dissected from three freshly killed, adult rabbits. Ligaments and facet joints were removed but each disc remained attached to bone. The discs were securely mounted in specially constructed bending apparatus. Ventral disc height and bending angle were measured simultaneously allowing the bending axis position to be calculated. Except for lumbosacral discs, the axis shifted ventrally during the transition from flexion to extension. The existence of separate flexion and extension axes has been reported for human lumbar discs; it is argued that similarity of disc structure leads to similar mechanical behaviour in rabbit and human discs. The positions of the two bending axes are such that flexion, but not extension, could damage the annulus fibrosus of the intervertebral disc.

Extraction of cardiac and respiratory motion cycles by use of projection data and its applications to nmr imaging (1990)

A technique of extracting cardiac and respiratory motion cycles by use of projection data is proposed and studied. These extracted cardiac and respiratory motion cycles are applied to the cine imaging of heart and motion artifact reduction in abdominal imaging instead of the conventional ECG gating devices. The basic concepts and their applications are discussed. Experimental results on human volunteers obtained with the KAIS 2.0-T whole-body NMR imaging system together with the pulse sequences used for the experiments are presented.
Phonology, Working Memory, and Foreign-language Learning (1992)

Three tasks were used to predict English learning by Finnish children over a three-year period. In the pseudoword repetition task the pupils had to repeat aloud tape-recorded pseudowords sounding like Finnish or English. In the pseudoword copying task the pupils saw strings of letters resembling Finnish or English words and copied them when they had disappeared from view. When comparing syntactic-semantic structures, the pupils had to find the syntactically matching pairs from two sets of Finnish sentences. Repetition and copying accuracy and the ability to compare syntactic-semantic structures predicted English learning. Intercorrelations between test scores and English and mathematics grades suggest that repetition and copying accuracy were specifically related to language learning. It is concluded that the ability to represent unfamiliar phonological material in working memory underlies the acquisition of new vocabulary items in foreign-language learning.
Research on reflection of L(0,1) guided wave from pipe elbow based on modal assurance criteria calculation (2017)

The reflection characteristic of L(0,1) mode guided wave from pipe elbow is investigated and a new analysis method based on modal assurance criteria (MAC) is proposed in this paper to investigate reflection of L(0,1) mode guided wave from pipe elbow. The mode conversion and effect of frequency, bending radius and bending angle have been analyzed through numerical simulation method. The guided wave reflection extent caused by elbow is expressed by guided wave modal assurance criteria. The trend of reflection extent changing with frequency and bending radius has been compared with numerical results and experimental results. The results indicate that partial L(0,1) mode converts to F(1,1) mode with the orientation being identical to the extrados-intrados direction. With the increase of frequency and bending radius, the amplitude of reflected guided wave decreases monotonously. With the increase of bending angle, the amplitude of reflected guided wave changes non-monotonically. The trend of guided wave reflection extent expressed by MAC changing with frequency and bending radius is identical with the numerical results. The experimental results verify the trend further. The research results will provide theoretical guide and a new analysis method for the inspection of pipes with elbows using L(0,1) mode guided wave.
Detection of Chromosomal Aneuploidy in Human Preimplantation Embryos by Next-Generation Sequencing1 (2014)

Embryos produced by assisted reproductive technologies are commonly associated with a high level of aneuploidy. Currently, 24-chromosome profiling of embryo biopsy samples by array-based methods is available to identify euploid embryos for transfer that have a higher potential for implantation and development to term. From a laboratory and patient perspective, there is a need to explore the feasibility of developing an alternative method for routine aneuploidy assessment of embryos that would be more comprehensive, cost-effective, and efficient. We speculated that aneuploidy could be readily assessed in test single-cell biopsy samples by first performing whole genome amplification followed by library generation, massively parallel shot-gun sequencing, and finally bioinformatics analysis to quantitatively compare the ratio of uniquely mapped reads to reference cells. Using Down syndrome as an example, the copy number change for chromosome 21 was consistently 1.5-fold higher in multiple cell and single-cell samples with a 47,XX,+21 karyotype. Applying the validated sequencing strategy to 10 sister blastomeres from a single human embryo, we showed that the aneuploidy status called by sequencing was consistent with short tandem repeat allelic profiling. These validation studies indicate that aneuploidy detection using sequencing-based methodology is feasible for further improving the practice of preimplantation genetic diagnosis.

<i>o</i>-Quinonemethides generated by condensation of 6-methylhept-5-en-2-ol with various salicylaldehydes in the presence of 30 mol% of fluoroboric acid etherate or triflic acid undergo [4+2]-cycloaddition reaction in situ to afford angularly fused pyranochromene derivatives in good yields and excellent diastereoselectivities.
Fourier transforms from strongly complementary observables (2015)

Ongoing work in quantum information emphasises the need for a structural understanding of quantum speedups: in this work, we focus on the quantum Fourier transform and the structures in quantum theory that enable it. We elucidate a general connection in any process theory between the Fourier transform and strongly complementary observables, i.e. Hopf algebras in dagger symmetric monoidal categories. We generalise the necessary tools of representation theory from fdHilb to arbitrary dagger symmetric monoidal categories. We define groups, characters and representations, and we prove their relation to strong complementarity. The Fourier transform is then defined in terms of pairs of strongly complementary observables, in both the abelian and non-abelian case. In the abelian case, we draw the connection with Pontryagin duality and provide categorical proofs of the Fourier Inversion Theorem, the Convolution Theory, and Pontryagin duality. Our work finds application in the novel characterisation of the Fourier transform for the category fRel of finite sets and relations. This is a result of interest for the study of categorical quantum algorithms, as the usual construction of the quantum Fourier transform in terms of Fourier matrices is shown to fail in fRel. Despite this, the process theoretic perspective on the Fourier transform is sensible in this setting. Furthermore, our categorical setting provides a generalisation of the abelian Fourier transform from finite-dimensional Hilbert spaces to finite-dimensional modules over arbitrary semirings, as well as a further generalisation to finite non-abelian groups, including a fully categorical generalisation of the Gelfand-Naimark theorem.
An application of the suárez reaction to the regiospecific and stereospecific synthesis of the C28-C42 segment of rapamycin (1993)

Specific lactonization of a TBS ether followed by iodinative scisson of a γ-lactol are the key elements of a strategy for maintaining continuous chemical distinction between the latent C34 and C32 hydroxyl groups of starring material 3 en route to 14, the C28-C42 fragment of rapamycin.
Solidification of Bi[sub 2]Sr[sub 2]Ca[sub 1]Cu[sub 2]O[sub [ital y]] and Bi[sub 2]Sr[sub 1. 75]Ca[sub 0. 25]CuO[sub [ital y]] (1993)

The solidification processes for the compositions Bi[sub 2]Sr[sub 2]CaCu[sub 2]O[sub [ital y]] (2212) and Bi[sub 2]Sr[sub 1.75]Ca[sub 0.25]CuO[sub [ital y]] (2201) were determined as a function of oxygen partial pressure. During solidification in argon, the superconducting phases were generally not observed to form for either composition. In both cases, the solidus is lowered to approximately 750 [degree]C. Solidification of Bi[sub 2]Sr[sub 1.75]Ca[sub 0.25]CuO[sub [ital y]] in Ar resulted in a divorced eutectic structure of Bi[sub 2]Sr[sub 2[minus][ital x]]Ca[sub [ital x]]O[sub [ital y]](22[ital x]) and Cu[sub 2]O while solidification of Bi[sub 2]Sr[sub 2]CaCu[sub 2]O[sub [ital y]] in Ar resulted in a divorced eutectic structure of Bi[sub 2]Sr[sub 3[minus][ital x]]Ca[sub [ital x]]O[sub [ital y]](23[ital x]) and Cu[sub 2]O. Solidification of Bi[sub 2]Sr[sub 1.75]Ca[sub 0.25]CuO[sub [ital y]] in O[sub 2] resulted in large grains of 2201 interspersed with small regions containing the eutectic structure of 22[ital x] and CuO/Cu[sub 2]O. Solidification of Bi[sub 2]Sr[sub 2]CaCu[sub 2]O[sub [ital y]] in partial pressures of 1%, 20%, and 100% oxygen resulted in multiphase samples consisting of 2212, 2201, some alkaline-earth cuprates, and both divorced eutectic structures found during solidification in Ar. For both compositions, these latter structures can be attributed to oxygen deficiencies present in themore » melt regardless of the overpressure of oxygen. These eutectic structures are unstable and convert into the superconducting phases during subsequent anneals in oxygen. The formation process of the 2212 phase during solidification from the melt was determined to proceed through an intermediate state involving the 2201 phase.« less

NEONATALY APPLIED SRIH-14 HAS IMMEDIATE AND PROLONGED INHIBITORY EFFECT ON (2006)

day) and adult (80 day) period of life. GH cellswere studied using the peroxidase-antiperoxidaseimmunocytochemical procedure. Morphometry and stereology wereused to evaluate changes in the number of GH-immunoreactive cellsper unit area, their volume and volume density. After SRIH-14 treatment,the most prominent decrease of all measured parameters wasobserved in the neonatal period. SRIH-14 induced a significantdecrease of GH cell volumes and volume densities in the juvenile,peripubertal and adult periods of life. The number of GH-positive cellswas significantly decreased when examined immediately aftertreatment, but significantly increased in adult females. Body weight,absolute or relative pituitary weights were not affected in any of theexamined age groups. These findings suggest that neonatal SRIH-14treatment exerts a significant immediate and prolonged inhibitory effecton GH cells, but does not affect the growth rate in female rats.Key words: female rats, somatostatin, somatotrophic cells,development
An Integrated System for Precise Genome Modification in Escherichia coli (2015)

We describe an optimized system for the easy, effective, and precise modification of the Escherichia coli genome. Genome changes are introduced first through the integration of a 1.3 kbp Landing Pad consisting of a gene conferring resistance to tetracycline (tetA) or the ability to metabolize the sugar galactose (galK). The Landing Pad is then excised as a result of double-strand breaks by the homing endonuclease I-SceI, and replaced with DNA fragments bearing the desired change via λ-Red mediated homologous recombination. Repair of the double strand breaks and counterselection against the Landing Pad (using NiCl2 for tetA or 2-deoxy-galactose for galK) allows the isolation of modified bacteria without the use of additional antibiotic selection. We demonstrate the power of this method to make a variety of genome modifications: the exact integration, without any extraneous sequence, of the lac operon (~6.5 kbp) to any desired location in the genome and without the integration of antibiotic markers; the scarless deletion of ribosomal rrn operons (~6 kbp) through either intrachromosomal or oligonucleotide recombination; and the in situ fusion of native genes to fluorescent reporter genes without additional perturbation.
Copper(II) Complexes of Arylhydrazone of 1H-Indene-1,3(2H)-dione as Catalysts for the Oxidation of Cyclohexane in Ionic Liquids (2018)

The copper(II) complexes [CuL(H2O)2]∙H2O (1) and [CuL(dea)] (2) [L = 2-(2-(1,3-dioxo-1H-inden-2(3H)-ylidene)hydrazinyl)benzenesulfonate, dea = diethanolamine] were applied as catalysts in the peroxidative (with tert-butyl-hydroperoxide or hydrogen peroxide) conversion of cyclohexane to cyclohexanol and cyclohexanone, either in acetonitrile or in any of the ionic liquids [bmim][NTf2] and [hmim][NTf2] [bmim = 1-butyl-3-methylimidazolium, hmim = 1-hexyl-3-methylimidazolium, NTf2 = bis(trifluoromethanesulfonyl) imide]. Tert-butyl-hydroperoxide led to better product yields, as compared to H2O2, with a selectivity directed towards cyclohexanone. The ILs showed a better performance than the conventional solvent for the copper complex 1. No catalytic activity was observed for 2 in the presence of an IL.

It is an imaging spectrometer with q spectral range from the UV/VIS to SWIR (212 nm 2384 nm). In this paper we describe shortly the current status of the operational processing chains from Level 0-Ib and Level 1b-2 that deliver Earth radiances, solar irradiance, trace gas total columns and profiles as well as cloud characteristics on an orbital basis. An outlook for future operational products is also given.
Variant identification in multi-sample pools by illumina genome analyzer sequencing. (2011)

Multi-sample pooling and Illumina Genome Analyzer (GA) sequencing allows high throughput sequencing of multiple samples to determine population sequence variation. A preliminary experiment, using the RET proto-oncogene as a model, predicted ≤ 30 samples could be pooled to reliably detect singleton variants without requiring additional confirmation testing. This report used 30 and 50 sample pools to test the hypothesized pooling limit and also to test recent protocol improvements, Illumina GAIIx upgrades, and longer read chemistry. The SequalPrep(TM) method was used to normalize amplicons before pooling. For comparison, a single 'control' sample was run in a different flow cell lane. Data was evaluated by variant read percentages and the subtractive correction method which utilizes the control sample. In total, 59 variants were detected within the pooled samples, which included all 47 known true variants. The 15 known singleton variants due to Sanger sequencing had an average of 1.62 ± 0.26% variant reads for the 30 pool (expected 1.67% for a singleton variant [unique variant within the pool]) and 1.01 ± 0.19% for the 50 pool (expected 1%). The 76 base read lengths had higher error rates than shorter read lengths (33 and 50 base reads), which eliminated the distinction of true singleton variants from background error. This report demonstrated pooling limits from 30 up to 50 samples (depending on error rates and coverage), for reliable singleton variant detection. The presented pooling protocols and analysis methods can be used for variant discovery in other genes, facilitating molecular diagnostic test design and interpretation.

Lee-Yang edge singularities in lattice QCD : A systematic study of singularities in the complex $\mu_B$ plane using rational approximations (2021)

A new approach is presented to explore the singularity structure of lattice QCD at imaginary chemical potential. Our method can be seen as a combination of the Taylor expansion and analytic continuation approaches. Its novelty lies in using rational (Pad\'e) approximants for studying Lee Yang edge singularities. The motivation for using rational approximants will be exhibited. We will provide some confidence in our approach based on numerical experiments performed on well-motivated "toy models". Our focus lies in identifying singularities of the net-baryon number density in the complex $\mu_B$ plane. To this end we have found signatures of the Roberge-Weiss critical point(and Chiral singularities -- subject to some caveats). In this contribution we will discuss the setup, simulation parameters and results obtained for 2+1 flavor QCD in the complex $\mu_B/T$ plane.
IEQ and the impact on building occupants (2002)

Research into indoor environmental quality (IEQ) and its effects on health, comfort and performance of occupants is becoming increasingly essential. Facility managers are interested in IEQ's close relationship to energy use. Employers hope to enhance employee comfort and productivity, reduce absenteeism and health-care costs, and reduce risk of litigation. The rising interest in this field has placed additional pressure on the research community for practical guidelines on creating a safe, healthy and comfortable indoor environment.
