Free electron laser operation in the whistler mode (1994)

The introduction of a strongly magnetized plasma in the inner region of a free electron laser opens up the possibility of generating coherent radiation in the slow whistler mode using mildly relativistic electron beams. The frequency of emission, however, is limited to below the electron cyclotron frequency. The efficiency of the device can be enhanced by tapering the guide magnetic field.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Preserving the Archival Bond in Distributed Ledgers (2017)

Distributed cryptographic ledgers, such as the blockchain, are now being used in recordkeeping. However, they lack a key feature of more traditional recordkeeping systems needed to establish the authenticity of records and enable reliance on them for trustworthy recordkeeping. The missing feature is known in archival science as the archival bond -- the mutual relationship that exists among documents by virtue of the actions in which they participate. In this paper, we propose a novel data model and syntax using core web principles that can be used to address this shortcoming in distributed ledgers as recordkeeping systems.
Optoelectronic components for microwave photonic applications (2003)

Next generation terrestrial and satellite wireless access networks may take advantage of photonic technologies to overcome limitations of traditional RF techniques. Future airborne antennas are planned to be distributed over the entire aircraft, as well, ground based antennas are remote from the processing unit. All this applications share the need for low loss transmission and distribution of microwave signals (ranging from about 100 MHz to few ten GHz) which can be either large or narrow bandwidth. The low loss, low weight and size and high bandwidth capability of optical fibers and related optoelectronic systems make them a good candidate for the transmission and processing of microwave signals. However these optical links have to present low noise figure, low phase noise, good stability, and high linearity. We present recent progress on high speed directly modulated lasers and high speed high power photodiodes developed for these applications.
Cancer nursing (1986)

This article addresses the development of cancer nursing as a specialty. It highlights the efforts of nurses around the world as they seek to understand the disease called cancer and the complexity of the treatments used. It emphasizes the role of nurses in the international community as they respond to the common challenge to obtain more cancer information and learn how to provide the care, teaching, and support that patients and their families need. As cancer nursing has evolved as a specialty in the United States, so has it also begun to evolve as a specialty in various parts of the world. What it means to be international, a historical overview of events that occurred in response to the need and demand for more information, and future directions for cancer nurses everywhere are presented.
The Properties of Binary Mixtures of Ethoxylated Octyl Phenols with Ethoxylated Fluorinated Alkanols at the Water/Air Interface (2011)

Abstract Surface tension measurements were carried out for systems containing binary mixtures of ethoxylated tert ‐octylphenols (with an average of 10 or 16 ethylene oxide groups—HC8PEO10 and HC8PEO16, respectively) with perfluorinated n ‐alcohol ethoxylates (fluoropentanol with an average of 10 ethylene oxide groups FC5EO10, and fluorohexanol with an average of 14 ethylene oxide groups FC6EO14). The obtained results and calculations indicate that fluorinated surfactants have the better efficiency and effectiveness in the reduction of surface tension of water that the hydrocarbonated alkyl phenol ethoxylates and that their mole fraction in the mixed monolayer at water–air interface for mixtures containing a 0.2 molar fraction of fluorinated surfactants in bulk phase is considerable higher than in the bulk phase. At concentrations of mixtures corresponding to saturated monolayer at water‐air interface there is a synergetic effect in the reduction of γ LV for a mixture of HC8PEO16 + FC5EO10 at a 0.2 molar fraction of HC8PEO16; however, taking into account the lowest value of the molecular interaction parameter for mixed micelles calculated on the basis of Rosen approach, the result is that the best synergism takes place for mixture of HC8PEO16 + FC6EO14 at a 0.2 molar fraction of HC8PEO16. Moreover, the ability of the mixed monolayer formation relative to the mixed micelle formation varies with the concentration and composition of the studied mixtures. Graphical Abstract The comparison between values of the free energy at water‐air interface ( ) and the standard Gibbs energy of micellization, , for aqueous solutions of hydrocarbon (HC8PEO10, HC8PEO16) and fluorinated (FC6EO14, FC5EO10) surfactants and their two binary mixtures.
Whole-cell conversion of l-glutamic acid into gamma-aminobutyric acid by metabolically engineered Escherichia coli (2016)

A simple and high efficient way for the synthesis of gamma-aminobutyric acid (GABA) was developed by using engineered Escherichia coli as whole-cell biocatalyst from l-glutamic acid (l-Glu). Codon optimization of Lactococcus lactis GadB showed the best performance on GABA production when middle copy-number plasmid was used as expression vector in E. coli BW25113. The highest production of GABA reached 308.96 g L(-1) with 99.9 mol% conversion within 12 h, when E. coli ΔgabAB (pRB-lgadB) concentrated to an OD600 of 15 in 3 M l-Glu at 45 °C. Furthermore, the strain could be reused at least three cycles in 2 M crude l-Glu with an average productivity of 40.94 g L(-1) h(-1). The total GABA yield reached 614.15 g L(-1) with a molar yield over 99 %, which represented the highest GABA production ever reported. The whole-cell bioconversion system allowed us to achieve a promising cost-effective resource for GABA in industrial application.
Involvement of Large‐Conductance Ca2+‐Activated K+ Channels in both Nitric Oxide and Endothelium‐Derived Hyperpolarization‐Type Relaxation in Human Penile Small Arteries (2013)

Large-conductance Ca(2+) -activated K(+) channels (BKC a ), located on the vascular smooth muscle, play an important role in regulation of vascular tone. In penile corpus cavernosum tissue, opening of BKC a channels leads to relaxation of corporal smooth muscle, which is essential during erection; however, there is little information on the role of BKC a channels located in penile vascular smooth muscle. This study was designed to investigate the involvement of BKC a channels in endothelium-dependent and endothelium-independent relaxation of human intracavernous penile arteries. In human intracavernous arteries obtained in connection with transsexual operations, change in isometric force was recorded in microvascular myographs, and endothelium-dependent [nitric oxide (NO) and endothelium-derived hyperpolarization (EDH)-type] and endothelium-independent (NO-donor) relaxations were measured in contracted arteries. In penile small arteries contracted with phenylephrine, acetylcholine evoked NO- and EDH-type relaxations, which were sensitive to iberiotoxin (IbTX), a selective blocker of BKC a channels. Iberiotoxin also inhibited relaxations induced by a NO-donor, sodium nitroprusside. NS11021, a selective opener of BKC a channels, evoked pronounced relaxations that were inhibited in the presence of IbTX. NS13558, a BKC a -inactive analogue of NS11021, failed to relax human penile small arteries. Our results show that BKC a channels are involved in both NO- and EDH-type relaxation of intracavernous penile arteries obtained from healthy men. The effect of a selective opener of BKC a channels also suggests that direct activation of the channel may be an advantageous approach for treatment of impaired endothelium-dependent relaxation often associated with erectile dysfunction.
Extracting noble metals from industrial solutions and waste waters with biosorbents (2009)

The chemical composition of various industrial solutions of the Shchelkovo Plant of Secondary Noble Metals is evaluated. It is established that the excess content of heavy metals with respect to gold and silver is larger by a factor of more than 1000. The microbial biomasses of various systematic groups are approved for extracting Au and Ag from solutions with a high salt background. The appropriateness of selectively extracting heavy metals from such complex solutions is shown. The behavior of heavy metals is investigated for sorption on biosorbents from individual solutions within the pH limits of 1.0–6.0 for the medium. The decisive significance of the pH of the solution (within the limits 1.0–3.0) on selectively extracting Ag from industrial solutions is determined. The notion that silver and heavy metals are attributed to different groups of metals by varying the degree of sorption with microorganisms, depending on the pH medium, is confirmed. The specific behavior of the biomass cells in the acidic medium also promotes the separation of these elements. Testing the biosorbed extraction of silver from the industrial solution on a granulated lincomycin biomass is approved under industrial conditions. The average degree of extraction was Cu ≤ 8.1, Ni 4.2, Zn 4.0, Fe 15.5%. The losses of biosorbent are about 70 g/m3 of the solution.
A Case of Intraosseous Hemangioma of the Nasal Bone (2014)

Intraosseous hemangioma is an uncommon tumor accounting for less than 1% of all primary bone tumors. The most frequent sites are the calvarium and vertebrae, however, involvement of the facial bones is rare. The diagnosis of facial bone hemangioma is difficult because the patients are usually asymptomatic, particularly in small lesions. Thus, intraosseous hemangioma of the nasal bone occurs extremely infrequent. Here we report a case of intraosseous hemangioma of the nasal bone treated with the surgical excision and reconstruction by autologous septal bone graft in a 62-year-old female.

Phases obtained from the frozen molten systems caesium–tin–halide and caesium–lead–halide (1973)

Phases and compositions obtained from the molten systems CsPbCl3–CsPbBr3 and CsPbClnBr3–n-CsSnClnBr3–n have been identified and compared with those from the CsSnCl3–CsSnBr3 system. X-Ray powder data are consistent with all of the products being single-phase solid solutions based on the perovskite lattice and in which there is random distribution of Group IV metal and halide ions. 119Sn Mössbauer data for the phases with cubic unit cells are characterised by high chemical shifts and narrow linewidths, indicative of the presence of tin(II) in octahedral sites, I.r. spectra of the cubic phases contain bands assignable to all of the possible stretching modes but only an average bending mode. There are no bands in the Raman spectra of the cubic phases. Colours obtained in the products are discussed in terms of the population of conductance bands by electrons from ns2 orbitals of the Group IV metal ions.
Path-dependent Monopole Braiding and Anyonic Dipoles in a Higgsed Tensor Gauge Model (2021)

We propose two-dimensional spin models obtained by the U(1) rank-2 tensor gauge theory with scalar or vector charges on the L_x \times L_y square lattice with p degrees of freedom per orbital and three orbitals per unit cell. The resulting spin model is a stabilizer model consisting of three mutually commuting projectors which are, in turn, obtained by Higgsing the mutually commuting Gauss's law operators and the magnetic field operators in the underlying U(1) lattice gauge theory. The spin model thus obtained is exactly solvable, with the ground state degeneracy (GSD) given by log_p GSD = 2 + (1 +{\delta}_{L_x mod p},0)(1 +{\delta}_{L_y mod p},0) when p is a prime number. Two types of dipoles, pristine and emergent, are identified. Both the monopoles and the dipoles are free to move, with certain restrictions on monopoles to hop only by p lattice spacing. The monopole-monopole braiding phase depends on the separation of the x or y coordinates of the initial monopole positions, whereas the monopole-dipole braiding is anyonic and depends on the product of the monopole charge and the dipole moment. The braiding phases can be understood as the Aharonov-Bohm phases of some emergent vector potentials.
Preparation of Chromosomal DNA from E. coli (2003)

This chapter describes a simple and rapid way of extracting and purifying chromosomal DNA from E. coli and many other species of bacteria. This procedure is essentially a simplified version of that described by Marmur in 1961 (1). The cells are lysed by treatment with a detergent and the mixture is deproteinized by phenol-chloroform extraction. Further purification can be achieved by treatment with ribonuclease and proteinase K. The resulting DNA, free of protein and RNA contamination, is sufficiently pure to be used for restriction digestion and cloning, e.g., in the preparation of gene libraries.
Leaky wave lenses for spoof plasmon collimation (2016)

We theoretically demonstrate the feasibility of collimating radiating spoof plasmons using a leaky wave lens approach. Spoof plasmons are surface waves excited along reactance surfaces realized through metallic corrugations. By employing a periodic perturbation to the geometric profile of this type of reactance surface, it becomes feasible to convert the excited spoof plasmons into free-space radiating leaky wave modes. It is demonstrated that by structurally modifying such a corrugated surface through the introduction of a non-uniform sinusoidally modulated reactance profile, then a tapered wavenumber, with a real part less than that of free space, can be established along the surface. In this way the radiating properties of the structure (amplitude and phase) can be locally controlled thereby creating a radiating effect similar to that of a non-uniform current distribution. By properly engineering the space dependent wavenumber along the corrugated surface, different regions of the structure will emit spoof plasmon energy at different angles with varying intensity. The combined effect is the emission of an electromagnetic wave exhibiting a converging wave-front that eventually collimates spoof plasmon energy at some desired focal point.
Crystallization and preliminary X-ray diffraction studies of a hyperthermophilic Rieske protein variant (SDX-triple) with an engineered rubredoxin-like mononuclear iron site (2006)

In place of the Rieske [2Fe-2S] cluster, an archetypal mononuclear iron site has rationally been designed into a hyperthermophilic archaeal Rieske [2Fe-2S] protein (sulredoxin) from Sulfolobus tokodaii by three residue replacements with reference to the Pyrococcus furiosus rubredoxin sequence. The resulting sulredoxin variant, SDX-triple (H44I/A45C/H64C), has been purified and crystallized by the hanging-drop vapour-diffusion method using 65%(v/v) 2-methyl-2,4-pentanediol, 0.025 M citric acid and 0.075 M sodium acetate trihydrate pH 4.3. The crystals diffract to 1.63 A resolution and belong to the triclinic space group P1, with unit-cell parameters a = 43.56, b = 76.54, c = 80.28 A, alpha = 88.12, beta = 78.82, gamma = 73.46 degrees. The asymmetric unit contains eight protein molecules.
Prenatal Nicotine Exposure Alters Lung Function and Airway Geometry through α7 Nicotinic Receptors (2012)

Abstract Maternal smoking during pregnancy has been associated with adverse effects on respiratory health. Whereas the epidemiologic link is incontrovertible, the mechanisms responsible for this association are still poorly understood. Although cigarette smoke has many toxic constituents, nicotine, the major addictive component in cigarette smoke, may play a more significant role than previously realized. The objectives of this study were to determine whether exposure to nicotine prenatally leads to alterations in pulmonary function and airway geometry in offspring, and whether α7 nicotinic acetylcholine receptors (nAChRs) mediate these effects. In a murine model of in utero nicotine exposure, pulmonary function, airway size and number, methacholine response, and collagen deposition were examined. Exposure periods included Gestation Days 7–21, Gestation Day 14 to Postnatal Day 7, and Postnatal Days 3–15. Prenatal nicotine exposure decreases forced expiratory flows in offspring through α7 nAChR–mediated signals, and the critical period of nicotine exposure was between Prenatal Day 14 and Postnatal Day 7. These physiologic changes were associated with increased airway length and decreased diameter. In addition, adult mice exposed to prenatal nicotine exhibit an increased response to methacholine challenge, even in the absence of allergic sensitization. Collagen expression was increased between adjacent airways and vessels, which was absent in α7 nAChR knockout mice. These observations provide a unified mechanism of how maternal smoking during pregnancy may lead to lifelong alterations in offspring pulmonary function and increased risk of asthma, and suggest potential targets to counteract those effects.
Reversal of the wavefront of nanosecond and subnanosecond light pulses in stimulated Brillouin scattering (1982)

An experimental investigation was made of the wavefront reversal parameters and of the reflection coefficient of a stimulated Brillouin scattering mirror made of CCl4; the measurements were carried out in a wide range of pump energies using pulses of 0.5–10 nsec duration. A reduction in the pulse duration reduced the dynamic range (i.e., the range of the pump energies) in which wavefront reversal was observed. Specially shaped pulses with different values of the contrast were used for the reversal of radiation with a high peak power.

Recognition and elimination of senescent erythrocytes: implication of antibodies specific for malonic dialdehyde-protein adducts, as demonstrated by flow cytometry. (1994)

Many different hypotheses have been formulated about the mechanisms of specific recognition of senescent red blood cells (RBC). It is usually assumed that novel epitopes appear on RBC membranes during ageing and are responsible for recognition of aged RBC by antibodies, which is followed by binding to mononuclear phagocytes and then phagocytosis. But these age-related epitopes have not so far been identified. Lipoperoxidation is known to produce aldehydes, among which malonic dialdehyde (MDA). This dialdehyde reacts with primary amino groups of biological molecules, producing 1-amino-3-imino propene (AIP) bridges, and we had previously shown that sera of healthy mammals contain antibodies recognizing epitopes containing AIP bridges (AbAIP). Lipoperoxidation is responsible for many age-related damages in RBC membrane, and we tried in the present work to determine whether age-related epitopes responsible for recognition of aged RBC were not derived from lipoperoxidation. Using flow cytometry techniques, we demonstrated that some of the epitopes recognized by immunoglobulins which bind to aged RBC contain AIP bridges, and that some of these RBC-bound immunoglobulins are AbAIP. Consequently, AbAIP/AIP bridges interactions appear to play a role in recognition and elimination of senescent RBC.
Theoretical Organometallic Chemistry (1981)

Organometallic chemists have synthesized a remarkable variety of new structural types. In these structures ligands, which are organic or inorganic molecules of variable independent stability, bind to one or more transition metal atoms. An approach to an understanding of the electronic structure, geometrical preferences, and reactivity of these complexes may be made if the molecule is "decomposed" conceptually into a metal fragment, ML(n), and a ligand. A library of the molecular orbitals of these fragments is becoming available. One then "reconstructs" the molecule by examining the interaction of the orbitals of the ligand, typically an organic molecule, with the orbitals of the ML(n), fragment.
Implicit Price Bundling of Retail Products: A Multiproduct Approach to Maximizing Store Profitability (1991)

The presence of demand interrelationships among substitute and complementary goods in retail stores was demonstrated by Mulhern in 1989 and was extended by Walters in 1991. Retail pricing strategies should incorporate such demand interdependencies to maximize store profitability. The authors review multiple-product pricing and develop a theoretical framework for retail pricing and promotion policies based on the implicit price bundling of related products. They empirically calibrate how the regular and deal prices of individual brands influence the sales of substitute and complementary items. More important, they demonstrate how retailers can maximize profitability by exploiting the interdependencies in demand that are present among retail products.
