description: The loading and kinetics of uptake for the inorganic ion-exchange material, α-zirconium phosphate, Zr(HPO4)2•H2O, were investigated with ions relevant to targeted alpha therapy including natural Cs+ (as a surrogate for 221Fr), natural Bi3+ (as a surrogate for 213Bi), and natural La3+ (as a surrogate for 225Ac). The narrow interlayer spacing of the α-phase (d = 7.6 Å) was found not to be advantageous with respect to rapid ion exchange, while converting the material to the hydrated Na-phase (d = 12.2 Å) allowed ion exchange to proceed more quickly, reaching equilibrium in under an hour. High loading was achieved for all three ions, at 72 ± 4% for Cs+ and 95 ± 5% for La3+ at pH 3 and 108 ± 10% for Bi3+ at pH 0.5. Leaching profiles of the loaded materials in a simulated human plasma environment of 10 mM carbonate buffer at pH 7.4 and 37°C, showed negligible release, with less than 1% in all cases. The ion-exchange properties and overall benign nature of zirconium phosphate highlight these materials as a promising platform for a targeted alpha therapy drug-delivery vehicle.

description: Uganda’s National Agricultural Advisory Services (NAADS), established in 2001, is a demand-driven extension program for developing farmer organizations and improving farmer production and welfare. The program is expected to be 50% client funded after 25 years. However, varying returns to extension services and inconclusive evidence about their effectiveness suggest that farmers may not be willing to pay for these services. Using a choice experiment, this study found that longer participation in NAADS increased farmers’ willingness to pay and that NAADS had a cost beneficial effect at farm level. The findings suggest that farmers are willing to pay for extension advice (US$0.20, which is higher than that found for most other African extension systems) if they see they are given good information, though they should not be asked to pay the full cost. Longer association with NAADS promoted the adoption of new crops, reduced the vulnerability of farms by increasing technology adoption and improved farmer welfare.

description: Absorption oscillator strengths have been determined from high-resolution spectra in the 967-972 Åregion of three CO isotopomers for transitions to the Rydberg levels 4{\it p$π$}(0), 3{\it d$π$}(1) and 4{\it p$σ$}(0), as well as to the mixed {\it E(6)} level recently characterized by Eidelsberg et al. (2004). Synchrotron radiation from the Super-ACO electron storage ring at Orsay (LURE) was used as a light source. Oscillator strengths were extracted from the recorded spectra by least-squares fitting of the experimental profiles with synthetic spectra taking into account the homogeneous and heterogeneous interactions of the four levels. Column densities were derived from fits to the 3{\it p$π$}(0) absorption band whose oscillator strength is well established. These are the first reported measurements for $^{13}$C$^{18}$O. For $^{12}$C$^{16}$O, our results are consistent with the larger values obtained in the most recent laboratory and astronomical studies.

Isotopic Scaling of Heavy Projectile Residues from the collisions of 25 MeV/nucleon 86Kr with 124Sn, 112Sn and 64Ni, 58Ni

description: The scaling of the yields of heavy projectile residues from the reactions of 25 MeV/nucleon 86Kr projectiles with 124Sn,112Sn and 64Ni, 58Nitargets is studied. Isotopically resolved yield distributions of projectile fragments in the range Z=10-36 from these reaction pairs were measured with the MARS recoil separator in the angular range 2.7-5.3 degrees. The velocities of the residues, monotonically decreasing with Z down to Z~26-28, are employed to characterize the excitation energy. The yield ratios R21(N,Z) for each pair of systems are found to exhibit isotopic scaling (isoscaling), namely, an exponential dependence on the fragment atomic number Z and neutron number N. The isoscaling is found to occur in the residue Z range corresponding to the maximum observed excitation energies. The corresponding isoscaling parameters are alpha=0.43 and beta=-0.50 for the Kr+Sn system and alpha=0.27 and beta=-0.34 for the Kr+Ni system. For the Kr+Sn system, for which the experimental angular acceptance range lies inside the grazing angle, isoscaling was found to occur for Z<26 and N<34. For heavier fragments from Kr+Sn, the parameters vary monotonically, alpha decreasing with Z and beta increasing with N. This variation is found to be related to the evolution towards isospin equilibration and, as such, it can serve as a tracer of the N/Z equilibration process. The present heavy-residue data extend the observation of isotopic scaling from the intermediate mass fragment region to the heavy-residue region. Such high-resolution mass spectrometric data can provide important information on the role of isospin in peripheral and mid-peripheral collisions, complementary to that accessible from modern large-acceptance multidetector devices.

The individual decay rates and the branching ratios among the strong decays determine their spin and parity. From such states the Regge trajectories are constructed in $(J, M^2)$ and $(n_r, M^2)$ planes and further predict the masses of higher excited states (1$^1D_2$, 1$^3D_3$, 3$^1S_0$, 3$^3S_1$, 1$^1F_3$, 1$^3F_4$, 2$^3D_3$, 3$^3P_2$ and 2$^3F_4$) lying on Regge lines by fixing their slopes and intercepts. Moreover, the strong decay rates and the branching ratios of these higher excited states are also examined, which can help the experimentalists to search these states into their respective decay modes.

description: The ion exchange of α-zirconium phosphate (ZrP) nanoparticles, highly crystalline zirconium phosphates prepared by the hydrothermal method, and epoxide functionalized zirconium phosphates were investigated. A series of exchange reactions involving both the surface and interlayer were used to determine exchange capacities for each environment and investigate the relationship between the interlayer and surface phosphates of ZrP. The resulting relationship was used to develop a new methodology to determine the average particle thickness within a sample of ZrP. Upon functionalization, the exchange capacities of derivatives prepared by surface functionalization (SF) and full functionalization (FF) were compared to the pristine ZrP, and an additional method was developed to determine the degree of functionalization in each sample.

description: Within the scope of a FRW cosmological model we have studied the role of spinor field in the evolution of the Universe when it is non-minimally coupled to the gravitational one. We have considered a few types of nonlinearity. It was found that if the spinor field nonlinearity describes an ordinary matter such as radiation, the presence of non-minimality becomes essential and leads to the rapid expansion of the Universe, whereas if the spinor field nonlinearity describes a dark energy, the evolution of the Universe is dominated by it and the difference between the minimal and non-minimally coupled cases become almost indistinguishable.

description: Vitamin and mineral deficiencies are a significant health problem in much of the developing world, causing illness, disability, mortality and reduced productivity. Biofortification of staple food crops has been proposed as a cost-effective solution. This paper calculates disabilityadjusted life years (DALYs) and economic surplus in order to analyze the potential health and economic benefits of cassava varieties developed to reduce vitamin A and iron deficiency in Nigeria and Kenya. Potential benefits from biofortification with vitamin A alone are estimated at $1,100 to $1,400 million in Nigeria and $67 to $81 million in Kenya, and from biofortification with both vitamin A and iron at $1,200 to $1,600 million in Nigeria and $105 to $110 million in Kenya. Costs per DALY saved are estimated at $4 to $6 for Nigeria, which compares very favorably with the costs for alternative methods such as fortification and supplementation. The estimated cost per DALY saved for Kenya is $56 to $87, which is similar to that for fortification and supplementation.

description: We suggest the possibility of observing and studying bright vortex solitons in attractive Bose-Einstein condensates in three dimensions with a radial trap. Such systems lie on the verge of critical stability and we discuss the conditions of their stability. We study the interaction between two such solitons. Unlike the text-book solitons in one dimension, the interaction between two radially trapped and axially free three-dimensional solitons is inelastic in nature and involves exchange of particles and deformation in shape. The interaction remains repulsive for all phase delta between them except for delta \approx 0.

description: A master equation description of the inherent dynamics is used to calculate the frequency-dependent linear thermo-visco-elastic response functions of a glass-forming liquid. From the imaginary parts of the isobaric specific heat, isothermal bulk modulus, and isobaric thermal expansion coefficient, we define a quantity $Λ_{Tp}(ω)$ with the property that $Λ_{Tp}(ω)=1$ is equivalent to having a one-parameter description of the linear thermo-visco-elastic response. This provides an alternative to the well-known criterion based on the Prigogine-Defay ratio.

description: Many techniques of metal ions removal have been already implemented; however, there is still need for novel, efficient, and non-toxic adsorbents dedicated to heavy metals. In a recent study, the adsorptive properties of four hybrid materials consisting of silica platform surface grafted with poly(amidoamine) dendrimers (PAMAM) with different amino-terminal components, toward two heavy metal ions: Ni(II) and Co(II), were examined. The materials showed maximal scavenging properties at pH 5.4. To determine the adsorptive nature of the hybrid materials, experimental isotherms were fitted by the Langmuir, the Freundlich, and the Dubinin–Radushkevich models. All materials exhibited adsorption capability best described by the Langmuir model. The calculated adsorption capacities qm ranged between 86.7 and 116.6 mg g−1 for Ni(II) ions and 32.8 and 101.1 mg g−1 for Co(II) ions, which strictly indicate the influence of grafting agent structure on adsorptive properties of hybrid materials. The values of mean free energy E and adsorption enthalpy ΔH° jointly indicated the physical nature of adsorption processes. From the thermodynamic studies, the values of ΔH°, ΔS°, and ΔG° were obtained, indicating the spontaneous and endothermic character of investigated Ni(II)/Co(II) metal ions adsorption process on SiO2–dendrimer hybrid materials. Moreover, the materials exhibited selectivity toward Ni(II) ions.

description: Nowadays, speech is becoming a more common, if not standard, interface to technology. This can be seen in the trend of technology changes over the years. Increasingly, voice is used to control programs, appliances and personal devices within homes, cars, workplaces, and public spaces through smartphones and home assistant devices using Amazon's Alexa, Google's Assistant and Apple's Siri, and other proliferating technologies. However, most speech interfaces are not accessible for Deaf and Hard-of-Hearing (DHH) people. In this paper, performances of current Automatic Speech Recognition (ASR) with voices of DHH speakers are evaluated. ASR has improved over the years, and is able to reach Word Error Rates (WER) as low as 5-6% [1][2][3], with the help of cloud-computing and machine learning algorithms that take in custom vocabulary models. In this paper, a custom vocabulary model is used, and the significance of the improvement is evaluated when using DHH speech.

description: When creating asteroid regolith simulant, it is necessary to have a model of asteroid regolith to guide and to evaluate the simulant. We created a model through evaluation and synthesis of the available data sets including (1) the returned sample from Itokawa by the Hayabusa spacecraft, (2) imagery from the Hayabusa and NEAR spacecraft visiting Itokawa and Eros, respectively, (3) thermal infrared observations from asteroids, (4) the texture of meteorite regolith breccias, and (5) observations and modeling of the ejecta clouds from disrupted asteroids. Comparison of the Hayabusa returned sample with other data sets suggest the surficial material in the smooth regions of asteroids is dissimilar to the bulk regolith, probably due to removal of fines by photoionization and solar wind interaction or by preferential migration of mid-sized particles into the smooth terrain. We found deep challenges interpreting and applying the thermal infrared data so we were unable to use those observations in the model. Texture of regolith breccias do not agree with other data sets, suggesting the source regolith on Vesta was coarser than typical asteroid regolith. The observations of disrupted asteroids present a coherent picture of asteroid bulk regolith in collisional equilibrium, unlike lunar regolith, HED textures, and the Itokawa returned sample. The model we adopt consists of power laws for the bulk regolith in unspecified terrain (differential power index -3.5, representing equilibrium), and the surficial regolith in smooth terrain (differential power index -2.5, representing disequilibrium). Available data do not provide adequate constraints on maximum and minimum particle sizes for these power laws, so the model treats them as user-selectable parameters for the simulant.

description: We have measured the nuclear transparency of the fundamental process $γ$ n $\to π^-$ p in $^4$He. These measurements were performed at Jefferson Lab in the photon energy range of 1.6 to 4.5 GeV and at $θ^π_{cm}= 70^\circ$ and $90^\circ$. These measurements are the first of their kind in the study of nuclear transparency in photoreactions. They also provide a benchmark test of Glauber calculations based on traditional models of nuclear physics. The transparency results suggest deviations from the traditional nuclear physics picture. The momentum transfer dependence of the measured nuclear transparency is consistent with Glauber calculations which include the quantum chromodynamics phenomenon of color transparency.

description: China has the highest proportion of lung cancer-related deaths. Drug therapy is the main tool of comprehensive anticancer treatment. However, most studies to date have focused on certain types of targets or immunotherapeutic modalities for drug safety; few studies have addressed the factors that influence ADRs for each type of drug in patients with lung cancer, and even fewer studies have explored the risk factors for certain types of ADRs. Based on it, we comprehensively evaluate the drug safety of patients and provide a clinical reference with a focus on lung cancer. We examined 767 reports of adverse drug reactions (ADRs) in patients with lung cancer and conducted a logistic regression analysis on the risk factors that may cause different types of organ system damage and serious ADRs. The logistic regression identified various independent risk factors for system organ damage, and ADRs involving erythrocyte abnormalities (P < 0.001), respiratory system damage (P < 0.001), and leukocyte and reticuloendothelial system abnormalities (P < 0.001) were more likely to be severe. Rare adverse reactions and different Clinical medication guidelines for molecular-targeted drugs were identified. These findings had certain practical significance in clinical safe drug use.

description: The extraction of hexavalent actinides An(VI) by tri-butyl phosphate (TBP) was investigated by electronic absorption and vibrational spectroscopies. Through a series of spectral subtractions, vibrational spectra associated with TBP, TBP–HNO3 adducts, and An(VI)–TBP complexes could be isolated. Investigation of U(VI) extracts indicated spectral features consistent with the formation of the expected [UO2(NO3)2(TBP)2] complex, but spectral features of other species were clearly evident. Likewise, multiple species were evident in the electronic absorption and vibrational spectra of TBP phases generated by extraction of Pu(VI). Although definitive characterization of the additional species formed could not be achieved in this work, it is hypothesized that they contain 3:1 TBP-to-An(VI) stoichiometry.

Updated Estimate of the Muon Magnetic Moment Using Revised Results from e+e- Annihilation

description: A new evaluation of the hadronic vacuum polarization contribution to the muon magnetic moment is presented. We take into account the reanalysis of the low-energy e+e- annihilation cross section into hadrons by the CMD-2 Collaboration. The agreement between e+e- and tau spectral functions in the pi pi channel is found to be much improved. Nevertheless, significant discrepancies remain in the center-of-mass energy range between 0.85 and 1.0 GeV, so that we refrain from averaging the two data sets. The values found for the lowest-order hadronic vacuum polarization contributions are a_mu[had,LO] = (696.3 +- 6.2[exp] +- 3.6[rad])e-10 (e+e- -based) and a_mu[had,LO] = (711.0 +- 5.0[exp] +- 0.8[rad] +- 2.8[SU2])e-10 (tau-based), where the errors have been separated according to their sources: experimental, missing radiative corrections in e+e- data, and isospin breaking. The corresponding Standard Model predictions for the muon magnetic anomaly read a_mu = (11,659,180.9 +- 7.2[had] +- 3.5[LBL] +- 0.4[QED+EW])e-10 (e+e- -based) and a_mu = (11,659,195.6 +- 5.8[had] +- 3.5[LBL] +- 0.4[QED+EW])e-10 (tau-based), where the errors account for the hadronic, light-by-light (LBL) scattering and electroweak contributions. The deviations from the measurement at BNL are found to be (22.1 +- 7.2 +- 3.5 +- 8.0)e-10 (1.9 sigma) and (7.4 +- 5.8 +- 3.5 +- 8.0)e-10 (0.7 sigma) for the e+e- and tau-based estimates, respectively, where the second error is from the LBL contribution and the third one from the BNL measurement.

Conformal Generators and Doubly Special Relativity Theories

description: In this paper, the relation between the modified Lorenz boosts, proposed in the doubly relativity theories and a linear combination of Conformal Group generators in $R^{1,d-1}$ is investigated. The introduction of a new generator is proposed in order to deform the Conformal Group to achieve the connection conjectured. The new generator is obtained trough a formal dimensional reduction from a free massless particle living in a $R^{2,d}$ space. Due this treatment it is possible to say that even DSR theories modify light cone structure in $R^{1,d-1}$, it could remains, in some cases, untouched in $R^{2,d}$.

description: The observed lightcurves and estimated sky rate of fast extragalactic x-ray transients (XRTs) discovered in archival Chandra data indicate that they belong to two distinct XRT populations. The first population of relatively short duration pulses, which typically last less than few minutes seems to be pulses of x-ray flashes (XRFs), which are nearby long duration gamma ray bursts viewed from far off axis. The second population of much longer pulses, which typically last hours, seems to be the early time afterglows of short gamma ray bursts (SGRBs) which are beamed away from Earth, as was shown in a previous paper.

The fixed-stress splitting scheme for Biot's equations as a modified Richardson iteration: Implications for optimal convergence

description: The fixed-stress splitting scheme is a popular method for iteratively solving the Biot equations. The method successively solves the flow and mechanic subproblems while adding a stabilizing term to the flow equation, which includes a parameter that can be chosen freely. However, the convergence properties of the scheme depend significantly on this parameter and choosing it carelessly might lead to a very slow, or even diverging, method. In this paper, we present a way to exploit the matrix structure arizing from discretizing the equations in the regime of impermeable porous media in order to obtain a priori knowledge of the optimal choice of this tuning/stabilization parameter.
