Palladium-Assisted Multicomponent Synthesis of 2-Aryl-4-aminoquinolines and 2-Aryl-4-amino[1,8]naphthyridines (2005)

A palladium-mediated multicomponent domino reaction leading to 2-aryl-4-amino-quinolines and 2-aryl-4-amino[1,8]naphthyridines is reported. The scope of the reaction was examined using carbon monoxide, two 2-ethynyl-arylamines, four aryl iodides, and 10 primary amines as substrates. The selection of the appropriate catalytic system was achieved testing several palladium/phosphine systems and overrides previously reported drawbacks associated with the use of primary amines in related reactions. Moreover several features concerning the role of both palladium [(0) and (II)] and phosphines are reported.

In Situ X‐Ray Observations and Microstructural Characterizations for Understanding Combustion Foaming and Reaction Processes to Synthesize Porous Al3Ti Composites From Al–Ti–B4C Powders (2021)

The combustion foaming behaviors to synthesize closed‐cellular porous Al 3 Ti composites are observed in situ using X‐ray radioscopy. The in situ observation of the thermal explosion (TE) mode foaming reveals that the combustion foaming process consists of six steps. The shape of the sample changes uniformly in the first three steps before the sample foams. First, the sample expands uniformly 1) gradual expansion) and maintains an almost constant volume for a fixed period 2) temporary steady state at a constant volume). During these stages, bubbles are not generated inside the sample. Subsequently, the sample shrinks uniformly 3) slight shrinkage). After these three steps, the bubbles are rapidly generated inside the sample 4) rapid foaming). Immediately after foaming, the sample shrinks drastically while bubbles are ruptured and combined 5) severe shrinkage and bubble coarsening). Finally, the sample solidifies as a porous metal 6) solidification). The sample fabricated under the self‐propagating high‐temperature synthesis (SHS) mode includes graded microstructures corresponding to steps (1)–(4). The microstructures of the samples foamed under the TE and SHS modes are characterized. These results are used for discussing the elementary reaction steps arising at steps (1)–(4).
On the origin of electrically active defects in AlGaN alloys grown by organometallic vapor phase epitaxy (1996)

Shallow and deep centers were studied by means of temperature dependent Hall effect and photoluminescence (PL) measurements in two sets of undoped n-AlGaN samples grown by organometallic vapor phase epitaxy. The samples of these two series were grown under different conditions and had, as a result, electron concentrations differing by several orders of magnitude. The composition dependence of ionization energies of dominant donors in these two sets of samples is very different indicating that different types of centers are involved, but in both cases they are most probably related to some native defects. These defects behave as hydrogen-like donors for low Al compositions and become increasingly deeper with increasing Al content. The shallow-deep transition occurs at about x=0.2 in the low conductivity AlxGa1−xN series and at about x=0.5 for the high conductivity series. Several PL bands were detected in AlGaN and it is shown that the band at 3.05 eV is due to a radiative transition between deep donors in the upper part of the band gap and holes in the valence band or on shallow acceptors. For the yellow luminescence band at 2.25 eV it is demonstrated that this band consists of two overlapping bands and that the dominant band is due to a transition between the native donors and a carbon-related deep center.
Volumetric Analysis from a Harmonized Multisite Brain MRI Study of a Single Subject with Multiple Sclerosis (2017)

Facile, Economic and Size-Tunable Synthesis of Metal Arsenide Nanocrystals (2016)

Synthesis of colloidal nanocrystals (NC) of important arsenide nanomaterials (e.g., InAs, Cd3As2) has been limited by the lack of convenient arsenic precursors. Here we address this constraint by identifying a convenient and commercially available As precursor, tris-dimethylaminoarsine (As(NMe2)3), which can be used to prepare high quality InAs NCs with controlled size distributions. Our approach employs a reaction between InCl3 and As(NMe2)3 using diisobutylaluminum hydride (DIBAL-H) to convert As(NMe2)3 in situ into reactive intermediates AsHx(NMe2)3–x, where x = 1,2,3. NC size can be varied by changing DIBAL-H concentration and growth temperature, with colloidal solutions of InAs showing size dependent absorption and emission features tunable across wavelengths of 750 to 1450 nm. We also show that this approach works well for the colloidal synthesis of Cd3As2 NCs. By circumventing the preparation of notoriously unstable and dangerous arsenic precursors (e.g., AsH3 and As(SiMe3)3), this work improves the synthetic accessibility of arsenide-based NCs and, by extension, the potential of such NCs for use in infrared (IR) applications such as communications, fluorescent labeling and photon detection.

Electronic structure and optoelectronic properties of transparent p-type conducting CuAlO2 (2000)

Electrical and optical properties of CuAlO2, a p-type conducting transparent oxide, were examined for the thin films prepared by the pulsed laser deposition technique. The indirect and direct allowed optical band gaps were evaluated to be ∼1.8 and ∼3.5 eV, respectively. The conductivity at 300 K was ∼3×10−1 S cm−1 and its temperature dependence is of the thermal-activation type (activation energy ≈0.2 eV) at temperatures &amp;gt;220 K but is of the variable-range hopping type (log σ∝T−1/4) at &amp;lt;220 K. It was inferred that an admixed state of Cu 3d and O 2p primarily constitutes the upper valence band, which controls transport of positive holes, from a combined information on ultraviolet photoemission spectrum with x-ray photoemission spectrum. An energy band calculation by full-potential linearized augmented plane wave method substantiated the experimental findings. The present results gave a solid basis for our working hypothesis [Nature (London) 389, 939 (1997)] for chemical design of p-type conducting transparent oxides.
Pharmacogenomic and clinical data link non-pharmacokinetic metabolic dysregulation to drug side effect pathogenesis (2015)

Drug side effects cause a significant clinical and economic burden. However, mechanisms of drug action underlying side effect pathogenesis remain largely unknown. Here, we integrate pharmacogenomic and clinical data with a human metabolic network and find that non-pharmacokinetic metabolic pathways dysregulated by drugs are linked to the development of side effects. We show such dysregulated metabolic pathways contain genes with sequence variants affecting side effect incidence, play established roles in pathophysiology, have significantly altered activity in corresponding diseases, are susceptible to metabolic inhibitors and are effective targets for therapeutic nutrient supplementation. Our results indicate that metabolic dysregulation represents a common mechanism underlying side effect pathogenesis that is distinct from the role of metabolism in drug clearance. We suggest that elucidating the relationships between the cellular response to drugs, genetic variation of patients and cell metabolism may help managing side effects by personalizing drug prescriptions and nutritional intervention strategies.
Photo-induced charge state conversion of Eu2+ in Ca2ZnSi2O7 (2009)

Eu 2 + doped sorosilicate Ca2ZnSi2O7 (melilite) exhibits a broad band emission peaking at ∼600 nm (∼2 eV) due to the electric dipole allowed transition of 4f65d1 to 4f7 of Eu2+ by an excitation with blue light (460 nm). Strong O2− ligand field with low symmetry due to the layered tetragonal crystallographic structure of the melilite may play a dominant role in lowering the emission band energy to ∼2 eV. In addition, line emissions attributable to the transitions from D50 to F7J of Eu3+ ions are detected by an excitation with deep UV light with sub-360 nm wavelengths. This is due to the formation of transient Eu3+ ions via charge transfer from Eu2+ to the matrix. The lifetime of the transient Eu3+ ion is found to be 58 ms by a pump-probe measurement, in which UV pulse laser and green continuous wave laser are employed as pump and probe lights, respectively. Based on these results, the energy diagram of Eu2+ in Ca2ZnSi2O7 is proposed.
Hierarchical domain structures and in situ domain migration in the antiferroelectric ceramic PLSnZT (1993)

The crystallography and microstructure of an antiferroelectric ceramic of approximate composition Pb0.97La0.02(Zr0.65Sn0.25Ti0.10)O3 have been examined. Transmission electron microscopy (TEM), x-ray, and neutron powder studies were carried out. The cell is metrically tetragonal with a c/a ratio of 0.993 when indexed to the parent cubic perovskite cell. The structure exhibits both a commensurate supercell, believed to be associated with oxygen octahedra distortions, and an incommensurate modulation. The different crystallographic variants of the tetragonal antiferroelectric phase gave rise to a hierarchy of domain structures. Charging of TEM specimens having an incomplete conductive coating caused domain migration.
Physical modification plane: cross MAC/PHY scheduling and resource allocation (2022)

This chapter discusses the strategies for providing physical layer security (PLS) using current scheduling and resource allocation (RA) algorithms. PLS could be a useful notion for resource management that focuses on security. Scheduling and RA have been used to accomplish a number of objectives, including improving spectrum efficiency (SE) and energy efficiency (EE), as well as increasing fairness. Information security can be efficiently achieved by carefully allocating the available resources based on the PLS concept. This chapter will review the scheduling and RA and their popular methods. Performance indicators and fundamental PLS optimization issues are then discussed. The secure RA and the prevalent PLS scheduling strategies are then covered. The importance of PLS-based scheduling in downlink transmission in wireless networks is demonstrated. Finally, the potential difficulties are discussed, and it is anticipated that the reader will understand PLS-based scheduling strategies and be motivated to use them in the future.
An Inexpensive Device for Pulling Glass Microneedles for Injection of Small Arthropods1 (1968)

Hand-drawn fine-tipped glass needles have been used in this laboratory for several years to inject virus preparations into small insects such as leafhoppers and aphids. A certain amount of skill is involved in making these needles, and, in the hands of the inexperienced worker, the number of acceptable units per work period is sometimes discouragingly small.
Functional analogues of bleomycin: DNA cleavage by bleomycin and hemin-intercalators (1986)

New hemin-intercalators (Hem-G's) that cleave DNA were synthesized, on the basis of 2-amino-6-methyldipyrido[1,2-alpha:3',2'-d]imidazole (Glu-P-1) as an intercalator moiety. Hem-G's, which possess an intramolecular ligand of the ferrous ion (a histidine or imidazole moiety), cleave DNA very efficiently and act at guanine-pyrimidine sequences preferentially. Bleomycin (BLM) also cleaved DNA with the same base-sequence selectivity shown by Hem-G's. The 5'-terminus of the DNA fragments cleaved by Hem-G's or by BLM is a phosphoryl group, while the 3'-terminus of the cleaved DNA fragments does not possess a 3'-phosphoryl group. There are more than three kinds of 5'-end 32P-labeled DNA fragments, which can be substrates of terminal deoxynucleotidyl transferase (TdT). One of the 3'-termini of the cleaved DNA fragments is a 3'-hydroxy group. The mobility of the 3'-end 32P-labeled DNA fragment cleaved by Hem-G's or by BLM corresponds to the removal of pyrimidine bases having guanine at the 5'-side. The mobility of one kind of the cleaved 5'-end 32P-labeled DNA fragments corresponds to the removal of guanine having pyrimidine at the 3'-side, followed by 3'-dephosphorylation. We propose that there exist plural mechanisms for DNA cleavage by Hem-G's or by BLM. The deduced structures of the cleaved DNA fragments suggest that one of the mechanisms involves deletion of two nucleotide units from DNA.
Pareto rules for malaria super-spreaders and super-spreading (2019)

Heterogeneity in transmission is a challenge for infectious disease dynamics and control. An 80-20 "Pareto" rule has been proposed to describe this heterogeneity whereby 80% of transmission is accounted for by 20% of individuals, herein called super-spreaders. It is unclear, however, whether super-spreading can be attributed to certain individuals or whether it is an unpredictable and unavoidable feature of epidemics. Here, we investigate heterogeneous malaria transmission at three sites in Uganda and find that super-spreading is negatively correlated with overall malaria transmission intensity. Mosquito biting among humans is 90-10 at the lowest transmission intensities declining to less than 70-30 at the highest intensities. For super-spreaders, biting ranges from 70-30 down to 60-40. The difference, approximately half the total variance, is due to environmental stochasticity. Super-spreading is thus partly due to super-spreaders, but modest gains are expected from targeting super-spreaders.
Measurement of the tune-out wavelength for Cs133 at 880 nm (2021)

We perform a measurement of the tune-out wavelength, ${\ensuremath{\lambda}}_{0}$, between the ${D}_{1}$, ${6}^{2}{S}_{1/2}\ensuremath{\rightarrow}{6}^{2}{P}_{1/2}$, and ${D}_{2}$, ${6}^{2}{S}_{1/2}\ensuremath{\rightarrow}{6}^{2}{P}_{3/2}$, transitions for $^{133}\mathrm{Cs}$ in the ground hyperfine state $(F=3,{m}_{F}=+3)$. At ${\ensuremath{\lambda}}_{0}$, the frequency-dependent scalar polarizability is zero leading to a zero scalar ac Stark shift. We measure the polarizability as a function of wavelength using Kapitza-Dirac scattering of a $^{133}\mathrm{Cs}$ Bose-Einstein condensate in a one-dimensional optical lattice, and determine the tune-out wavelength to be ${\ensuremath{\lambda}}_{0}=880.21790{(40)}_{\text{stat}}{(8)}_{\text{sys}}$ nm. From this measurement we determine the ratio of reduced matrix elements to be ${|\ensuremath{\langle}6{P}_{3/2}\ensuremath{\parallel}d\ensuremath{\parallel}6{S}_{1/2}\ensuremath{\rangle}|}^{2}/{|\ensuremath{\langle}6{P}_{1/2}\ensuremath{\parallel}d\ensuremath{\parallel}6{S}_{1/2}\ensuremath{\rangle}|}^{2}=1.9808(2)$. This represents an improvement of a factor of 10 over previous results derived from excited-state lifetime measurements. We use the present measurement as a benchmark test of high-precision theory.
The role of nonclassical Fc receptor-associated, Ag-B antigens (Ia) in rat allograft enhancement. (1976)

The ability of a hyperimmune Lew anti-BN serum (HIS) to induce enhancement of (Lew/BN)F1 kidneys transplanted into Lew recipients was compared to that of the same antiserum that had been depleted of hemagglutinating anti-Ag-B antibodies by absorption with Brown-Norway (BN) RBC-absorbed sera (RAS) or platelet-absorbed sera (PAS). The RAS and PAS were as effective as the unabsorbed HIS in abrogating early rejection as assessed by renal function and promotion of long-term survival. The absorbed sera retained the capacity to block the mixed lymphocyte culture (MLC) between Lew and BN lymphocytes and to a lesser degree the MLC between Lew and BUF, WF, AUG, and ACI lymphocytes; however, strain specificity was clearly evident at high antiserum dilutions. Similarly, these absorbed sera retained the capacity to block the Fc receptor of BN lymphocytes, and this effect was completely strain specific. In contrast, hemagglutinating and cytotoxic antibodies eluted from platelets used for antiserum absorption did not react with Fc receptors as assessed by rabbit antisheep (IgG)-coated SRBC (EA) rosette formation. F(Ab')2 fragments of PAS also blocked EA rosettes. On the other hand, complement rosettes (EAC) were not inhibited by the HIS. The antibodies were therefore directed against the Fc receptor itself or a structure spatially or functionally closely related to it. Both the Fc receptors and the enhancing capacity of the antisera were strictly specific for the BN genotype. It is suggested that the anti-"Fc receptor" antibody could play an important role in the induction of enhancement by impairing host T-B collaboration as a result of its binding to graft allogeneic "Fc receptors" which appear to be analogous to the major histocompatibility complex (MHC)-coded Ia antigens of the mouse.
Thermoelectric properties and anisotropic electronic band structure on the In4Se3−x compounds (2009)

We report the high thermoelectric figure-of-merit (ZT) on the Se-deficient polycrystalline compounds of In4Se3−x (0.02≤x≤0.5) and the anisotropic electronic band structure. The Se-deficiency (x) has the effect of decreasing the semiconducting band gap and increasing the power factor. The band structure calculation for In4Se3−x (x=0.25) exhibits localized hole bands at the Γ-point and Y-S symmetry line, whereas the significant electronic band dispersion is observed along the c-axis. Here, we propose that the high ZT values on those compounds are originated from the anisotropic electronic band structure as well as Peierls distortion.

Impaired Myocardial Function and Oxygen Utilization Due to Protamine Sulfate in an Isolated Rabbit Heart Preparation (1990)

The myocardial effects of protamine, with and without heparin, were documented in this investigation. Isolated rabbit hearts (n = 30) were retrograde perfused with Krebs-Ringers bicarbonate solution aerated with 95% O2/5% CO2 through the aortic root (37 C, 80 mmHg). Developed left ventricular blood pressure, heart rate, coronary artery flow, contractility as reflected by peak +dp/dt, oxygen extraction (a-vO2), and oxygen consumption (VO2) were measured at baseline and continuously throughout the experiment. Protamine (25 micrograms, 50 micrograms, and 250 micrograms per mL of perfusate) was circulated in the Krebs-Ringers buffer to hearts perfused without heparin (groups I, II, and III) or hearts perfused with heparin added to the buffer solution, 0.1 IU/1.0 microgram protamine (groups IV, V, and VI). Blood pressure 4 minutes after protamine was less in groups III (-23 mmHg) and VI (-28 mmHg) than in groups I (-6 mmHg), II (-18 mmHg), IV (-1 mmHg), and V (-7 mmHg). Heart rate changes (beats/minute) at 4 minutes revealed similar dose-dependent reductions (III and VI: -51, -55; II and V: -36, -36; and I and IV: -20, -16, respectively). Coronary artery flow at 4 minutes was slightly increased in groups III (9 mL/minute) and VI (15 mL/minute), but was relatively unchanged in the other groups. Decreases in contractility were apparent in all groups 4 minutes after protamine was started: group I, -14%; II, -16%; III, -30%; IV, -7%; V, -15%; and VI, -34%. Similarly declines in oxygen extraction and consumption were noted in all groups at the same time period and were greater in groups III (-53%, -44%) and VI (-55%, -49%) than in groups I (-25%, -26%), II (-15%, -12%), IV (-48%, -49%) and V (-15%, -18%), with p less than or equal to 0.05 or p less than or equal to 0.01 compared to baseline. Three of ten hearts exposed to high-dose protamine stopped beating after 5 minutes. This investigation establishes, for the first time, that protamine has dose- and time-specific adverse effects on cardiac contractility. In addition protamine decreases myocardial a-vO2 and VO2. These changes may contribute to certain adverse events accompanying the clinical administration of protamine.
