description: This dissertation presents, solves, and estimates two sticky-price monetary models under rational expectations, to investigate the relationship between fiscal expenditure and the exchange rate. The first project extends the Driskill and Sheffrin (1981) (DS) model by adopting a detailed aggregate demand specification which includes a specific government purchases variable. We estimate the extended DS model for the DM/US$ exchange rate. As background to our extension, we also present an attempted replication, correction, and update of the DS results. Our replication and update are an improvement on the DS results. Most of our estimates are significant, correctly signed, and plausible; however, the restrictions imposed by the structural model and rational expectations are rejected. Our extended DS model estimation finds evidence for a negative, but insignificant, relationship between fiscal expenditure and the exchange rate. The second project adapts the Wickens (1985) model to a secular inflationary environment. We also modify the Wickens aggregate demand specification to capture dependence on real interest rate, and to specifically include a government purchases variable. In this model a permanent shock to the money supply could lead to either overshooting or undershooting of the exchange rate. However, our attempts at estimating the extended Wickens model for the Can$/US$ exchange rate, proved to be unsuccessful. An unconstrained version of the model finds some evidence for a link between fiscal expenditure and the exchange rate.

description: Internal working models are cognitive-affective-motivationaI representations that are richly interconnected within an hierarchical network. Differences in attachment style are attributed to systematic differences in working models. Adults with a dismissing attachment style are characterized by their disavowal of the need for close relationships. Previous research suggests their habitual use of defensive strategies facilitates the construction of working models that are poorly integrated with other mental representations in memory. It was hypothesized that as a result of this organization, dismissing adults have developmentally less mature working representations than adults with other attachment styles. Information about subjects' working representations of people in general and their parents was gathered using the Thematic Apperception Test and an early memories interview, respectively. Responses were analyzed using the Social Cognition and Object Relations Scale (Westen, 1995; Westen, Barends, Leigh, Mendel, & Silbert, 1990). A dismissing style was associated with an immature capacity to invest in relationships and moral standards for both people in general and parents. Working representations of mothers and fathers were highly associated. Yet, subjects evidenced greater investment in the relationship and morals of their mothers than fathers, and the complexity of their representations was greater for fathers than mothers. The discussion focuses on implications for the structure of working models in memory.

description: Exceptional points associated with non-hermitian operators, i.e. operators being non-hermitian for real parameter values, are investigated. The specific characteristics of the eigenfunctions at the exceptional point are worked out. Within the domain of real parameters the exceptional points are the points where eigenvalues switch from real to complex values. These and other results are exemplified by a classical problem leading to exceptional points of a non-hermitian matrix.

description: A new procedure for (1) the extraction and (2) the quantitative measurement of aromatic hydrocarbons from contaminated water is described. Solutions of polyisobutylene in isooctane (PIB/ISO) were prepared in three different concentrations at room temperature. The substrates: benzene, toluene, ethylbenzene, and xylene were extracted by the prepared polyisobutylene solutions. An aqueous stock solution of toluene, benzene, ethylbenzene and xylene, containing 150 ppm of each compound was prepared. Additionally, a toluene aqueous stock solution containing 500 ppm was made. In order to develop Beer-Lambert curves of the infrared (IR) absorption of each hydrocarbon these stock solutions were used to prepare standard solutions by dilution with pure water. Twenty five ml of hydrocarbon solution were transferred to a separatory funnel and 25 ml of PIB/ISO were poured into the funnel. The funnel was shaken gently for five minutes. The two layers, water and PIB/ISO, were separated immediately after the extraction. The aqueous sample was collected in a graduated cylinder. Two ml of sample were transferred from the graduated cylinder to a 1 cm quartz cuvette. The quartz cuvette was placed in an air remover apparatus for one minute to remove bubbles from the solution. In order to create the standards curves, the IR absorption of the hydrocarbons in the aqueous solutions was measured in a Bio-Rad SF7 Fourier Transform Infrared (FTIR) spectrometer and the data was stored on the hard disc. The quantitation was carried out using the Bio-Rad 2.21 software program. The single-pass extraction process was very efficient and the new analytical procedure was more sensitive than EPA Method 413.2 but does not require the use of Freon.

description: Despite beneficial cardiovascular effects, substantial long-term modulation of food pattern could only be achieved in a limited number of participants. The impact of attitude towards healthy nutrition (ATHN) on successful modulation of dietary behavior is unclear, especially in the elderly. We aimed to analyze whether the personal ATHN influences 12-month adherence to two different dietary intervention regimes within a 36-month randomized controlled trial. Methods: 502 subjects were randomized to an intervention group (IG; dietary pattern focused on high intake of unsaturated fatty acids (UFA), plant protein and fiber) or control group (CG; dietary recommendation in accordance with the German Society of Nutrition) within a 36-month dietary intervention trial. Sum scores for effectiveness, appreciation and practice of healthy nutrition were assessed using ATHN questionnaire during the trial ( n = 344). Linear regression models were used to investigate associations between ATHN and dietary patterns at baseline and at month 12. Results: Retirement, higher education level, age and lower body mass index (BMI) were associated with higher ATHN sum scores. ATHN was similar in CG and IG. Higher baseline intake of polyunsaturated fatty acids (PUFA) and fiber as well as lower intake in saturated fatty acids (SFA) were associated with higher scores in practice in both groups. The intervention resulted in a stronger increase of UFA, protein and fiber in the IG after 12 months, while intake of SFA declined ( p < 0.01). Higher scores in appreciation were significantly associated with higher intake of fiber and lower intake of SFA in the CG at month 12, whereas no associations between ATHN and macronutrient intake were observed in the IG after 12 months. Conclusions: While ATHN appeared to play a role in general dietary behavior, ATHN did not affect the success of the specific dietary intervention in the IG at month 12. Thus, the dietary intervention achieved a substantial modification of dietary pattern in the IG and was effective to override the impact of the individual ATHN on dietary behavior.

description: Though several theoretical models have been proposed to design electronic flat-bands, the definite experimental realization in two-dimensional atomic crystal is still lacking. Here we propose a novel and realistic flat-band model based on threefold degenerate $p$-orbitals in two-dimensional ionic materials. Our theoretical analysis and first-principles calculations show that the proposed flat-band can be realized in 1T layered materials of alkali-metal chalogenides and metal-carbon group compounds. Some of the former are theoretically predicted to be stable as layered materials (e.g., K$_2$S), and some of the latter have been experimentally fabricated in previous works (e.g., Gd$_2$CCl$_2$). More interestingly, the flat-band is partially filled in the heterostructure of a K$_2$S monolayer and graphene layers. The spin polarized nearly flat-band can be realized in the ferromagnetic state of a Gd$_2$CCl$_2$ monolayer, which has been fabricated in experiments. Our theoretical model together with the material predictions provide a realistic platform for the study of flat-bands and related exotic quantum phases.

description: Pair-instability supernovae (PISNe) are the ultimate cosmic lighthouses, capable of being observed at z<25 and revealing the properties of primordial stars at cosmic dawn. But it is now understood that the spectra and light curves of these events evolved with redshift as the universe became polluted with heavy elements because chemically enriched stars in this mass range typically lose most of their hydrogen envelopes and explode as bare helium cores. The light curves of such transients can be considerably dimmer in the near infrared (NIR) today than those of primordial PISNe of equal energy and progenitor mass. Here, we calculate detection rates for PISNe whose progenitors lost their outer layers to either line-driven winds or rotation at z<10, their detection limit in redshift for the James Webb Space Telescope (JWST). We find that JWST may be able to detect only Pop II (metal-poor) PISNe over the redshift range of z<4, but not their Pop III (metal-free) counterparts.

description: We have studied the radiation damage in diamond as a function of layer depth upon self-ion implantation with 9-MeV carbon ions and its recovery after annealing at 1000°C. Raman and photoluminescence spectra show substantial damage of the lattice, namely, amorphization, neutral vacancies, and interstitial defects. Damage is maximum in the stopping layer at a depth of 4 μm. After annealing there is some recovery of the lattice, but the residual damage increases with fluence, up to about 2E16 ions/cm2. At this fluence the stopping layer becomes highly disordered and does not heal with annealing. Surprisingly, for higher fluence values, of about 5E16 ions/cm2, there is almost no residual damage. After full amorphization is reached, the layers appear to recrystallize by solid phase epitaxy (SPE), using the pristine diamond layers underneath as a template. These results prove that graphitization of diamond after annealing can be avoided in deeply buried layers, implanted at fluences much higher than expected. High fluences, in fact, can lead to high quality diamond layers. If SPE can be confirmed, it would have a great interest for diamond device applications, as it allows for higher doping levels.

description: Physiological responses of plants to elevated carbon dioxide (CO2) and nitrogen (N) availability are ecologically important because of increased atmospheric CO2 concentrations and N enrichment in many ecosystems. Here, the effects of N availability on the responses of six wetland plant species to elevated CO2 levels are examined in terms of growth and root exudation. Six species of emergent plant species typically found in marshes were incubated under two levels of CO2 (370 and 740 ppm) and two levels of N (0 and 8.8 mg N L−1). Elevated CO2 did not affect shoot biomass, root biomass, and height significantly, regardless of N levels. The C/N ratio of plant species increased in response to elevated CO2 levels, but this effect varied by species. All species released higher amounts of dissolved organic carbon under elevated CO2 compared with ambient air conditions. This response was limited under low soil N concentrations. By contrast, phenolic content increased significantly with elevated CO2 under low-N treatment. The findings suggest that elevated CO2 is not responsible for biomass accumulation of emergent wetland plant species, but does elicit changes in the quantity and quality of root exudates, which are, in turn, dependent on N availability to plant species.

Crystal-field study of magnetic anisotropy in rare earth compounds

Publisher: name: American University
Year: 2023

description: By considering the exchange interaction and crystal field effect, a computer program is modified to model the easy direction of magnetization for rare-earth compounds under a given symmetry of crystal-field, and a calculation is made of the easy direction of magnetization of Tb1-xDyxZn. It is assumed that the spontaneous magnetization is a direct consequence of the exchange interaction and that the magnetic anisotropy arises from the crystal-field effects. The exchange interaction is treated with the mean-field theory, and the crystal-field is described in the equivalent operator method. All of the matrix elements of the Stevens operators are calculated. By transforming the crystalline coordinates to the magnetization coordinates, the definitive magnetization reorientation diagram of Tb1-xDyxZn has been established. The results of the calculation are compared to the existing experimental data; that is, for the rare-earth compound of Tb1- xDyxZn the actual low-temperature easy direction of magnetization could be neither [100] or [110], but a set of non-symmetry axes [uv0] where u and v vary with the concentration x and temperature T. In addition, the change of free energy is numerically calculated in different directions for both of TbZn and DyZn. The results show that there are large magnetic anisotropies at low temperature for TbZn and DyZn. The expected compensation in the magnetic anisotropy and in the alteration of the transition temperature is verified theoretically by the substitution of the Dy in the TbZn. By examining the effect of the crystal-field parameters, the free energy does not have a sensitive dependence on A4, but A6 is critical in deciding the value of the free energy. From the diagrams of the minimum free energy vs. temperature, we see that, at low temperature, the internal energy increases faster as the temperature increases than does the entropy for the magnetic system. At high temperature, this behavior is reversed. It is found that the excited states are not very important for the magnetic system at low-temperatures because the free energy has the same value as the lowest energy eigenvalue in that case. For the magnetization reorientation diagram of Tb1-xDyxZn, it is found that, to get agreement with experiment, the values of the crystal-field parameters must be chosen for Dy3+ that are of opposite sign to those predicted by Morin. Possible reasons for the discrepancy are discussed.

description: In this paper we use a 50ks XMM-Newton pointing overlapping with the Phoenix Deep Survey, a homogeneous radio survey reaching muJy sensitivities, to explore the X-ray properties and the evolution of star-forming galaxies. UV, optical and NIR photometry is available and is used to estimate photometric redshifts and spectral types for radio sources brighter than R=21.5mag (total of 82). Sources with R<21.5mag and spiral galaxy SEDs (34) are grouped into two redshift bins with a median of z=0.240 and 0.455 respectively. Stacking analysis for both the 0.5-2 and 2-8keV bands is performed on these subsamples. A high confidence level signal (>3.5sigma) is detected in the 0.5-2keV band corresponding to a mean flux of ~3e-16cgs for both subsamples. This flux translates to mean luminosities of ~5e40 and 1.5e41cgs for the z=0.240 and 0.455 subsamples respectively. Only a marginally significant signal (2.6sigma) is detected in the 2-8keV band for the z=0.455 subsample. We argue that the stacked signal above is dominated by star-formation. The mean L_X/L_B ratio and the mean L_X of the two subsamples are found to be higher than optically selected spirals and similar to starbursts. We also find that the mean L_X and L_1.4 of the faint radio sources studied here are consistent with the L_X-L_1.4 correlation of local star-forming galaxies. Moreover, the X-ray emissivity of sub-mJy sources to z~0.3 is found to be elevated compared to local HII galaxies. The observed increase is consistent with L_X evolution of the form (1+z)^3. Assuming that our sample is indeed dominated by starbursts this is direct evidence for evolution of such systems at X-ray wavelengths. Using an empirical L_X to SFR conversion we estimate a global SFR density at z~0.3 of \~0.029M_o/yr/Mpc in agreement with previous studies.

description: The purpose of this study was to explore the effects of exposure to the Curriculum and Evaluation Standards: Addenda Series 5--8 on student's performance. This population experienced six activities. The study investigated the effects of these activities on (1) Test scores at end of the seventh grade which was compared to the test scores at the end of the sixth grade. (2) To what degree did the students employ the strategies to which they were exposed during problem solving? An important result of this study indicates that the students in the experimental group did better on the year-end final examination than the control group. Further. problems that were analyzed revealed that the experimental group chose better strategies than the control group even when the responses were wrong. Recommendations for further study are outlined.

description: We consider the time-reversal odd dynamics of the bilayer graphene at low energies in the quantum Hall regime. A generating functional for the effective action that captures the electromagnetic response to all orders in momentum and frequency is presented and evaluated to the third order in the space-time gradient $\mathcal O(\partial^3)$. In addition, we calculate the Hall viscosity and derive an explicit relationship with the $q^2$ coefficient of the Hall conductivity. It is reminiscent of the Hoyos--Son relation in the Galilean invariant systems, which can be recovered in the limit of large filling factor $N$.

description: In the string holographic dual of large-N_c QCD with N_f flavours of Kruczenski et al, the eta' meson is massless at infinite N_c and dual to a collective fluctuation of N_f D6-brane probes in a supergravity background. Here we identify the string diagrams responsible for the generation of a mass of order N_f/N_c, consistent with the Witten-Veneziano formula, and show that the supregravity limit of these diagrams corresponds to mixings with pseudoscalar glueballs. We argue that the dependence on the theta-angle in the supergravity description occurs only through the combination theta + 2 \sqrt{N_f} eta' / f_pi, as dictated by the U(1) anomaly. We provide a quantitative test by computing the linear term in the eta' potential in two independent ways, with perfect agreement.

description: Black phosphorus has recently attracted significant attention for its highly anisotropic properties. A variety of ultrafast optical spectroscopies has been applied to probe the carrier response to photoexcitation, but the complementary lattice response has remained unaddressed. Here we employ femtosecond electron diffraction to explore how the structural anisotropy impacts the lattice dynamics after photoexcitation. We observe two timescales in the lattice response, which we attribute to electron-phonon and phonon-phonon thermalization. Pronounced differences between armchair and zigzag directions are observed, indicating a nonthermal state of the lattice lasting up to ~60 ps. This nonthermal state is characterized by a modified anisotropy of the atomic vibrations compared to equilibrium. Our findings provide insights in both electron-phonon as well as phonon-phonon coupling and bear direct relevance for any application of black phosphorus in nonequilibrium conditions.

description: The purpose of this study was to explore the effects of exposure to the Curriculum and Evaluation Standards: Addenda Series 5--8 on student's performance. This population experienced six activities. The study investigated the effects of these activities on (1) Test scores at end of the seventh grade which was compared to the test scores at the end of the sixth grade. (2) To what degree did the students employ the strategies to which they were exposed during problem solving? An important result of this study indicates that the students in the experimental group did better on the year-end final examination than the control group. Further. problems that were analyzed revealed that the experimental group chose better strategies than the control group even when the responses were wrong. Recommendations for further study are outlined.

description: The use of nonlinear PDEs has led to significant advancements in various fields, such as physics, biology, ecology, and quantum mechanics. However, finding multiple solutions for nonlinear PDEs can be a challenging task, especially when suitable initial guesses are difficult to obtain. In this paper, we introduce a novel approach called the Companion-Based Multilevel finite element method (CBMFEM), which can efficiently and accurately generate multiple initial guesses for solving nonlinear elliptic semi-linear equations with polynomial nonlinear terms using finite element methods with conforming elements. We provide a theoretical analysis of the error estimate of finite element methods using an appropriate notion of isolated solutions, for the nonlinear elliptic equation with multiple solutions and present numerical results obtained using CBMFEM which are consistent with the theoretical analysis.

description: We fabricated two dimensional photonic crystal structures in zinc oxide films with focused ion beam etching. Lasing is realized in the near ultraviolet frequency at room temperature under optical pumping. From the measurement of lasing frequency and spatial profile of the lasing modes, as well as the photonic band structure calculation, we conclude that lasing occurs in the strongly localized defect modes near the edges of photonic band gap. These defect modes originate from the structure disorder unintentionally introduced during the fabrication process.

description: We propose a new four-dimensional orthant-symmetric 128-ary modulation format (4D-OS128) with a spectral efficiency of 7bit/4D-sym. The proposed format fills the gap between polarization-multiplexed 8- and 16-ary quadrature-amplitude modulation (PM-8QAM and PM-16QAM).Numerical simulations show that 4D-OS128 outperforms two well-studied 4D geometrically-shaped modulation formats: 128SP-16QAM and 7b4D-2A8PSK by up to 0.65dB for bit-interleaved coded modulation at the same spectral efficiency. These gains are experimentally demonstrated in a 11$\times$233Gbit/s wavelength division multiplexing (WDM) transmission system operating at 5.95 bit/4D-sym over 6000km and 9000km for both EDFA-only and hybrid amplification scenarios, respectively. A reach increase of 15% is achieved with respect to 128-ary set-partitioning 16QAM. Furthermore, the proposed 4D-OS128 is also compared to $\boldsymbol{D}_4$ lattice-based constellation and probabilistically-shaped 16QAM with finite blocklength via simulation.
