description: The Arctic is undergoing a rapid environmental shift with increasing temperatures and precipitations expected to continue over the next century. Yet, little is known about how microbial communities and their underlying metabolic processes will respond to ongoing climatic changes. To address this question, we focused on Lake Hazen, NU, Canada. As the largest High Arctic lake by volume, it is a unique site to investigate microbial responses to environmental changes. Over the past decade, glacial coverage of the lake has declined. Increasing glacial runoff and sedimentation rates in the lake has resulted in differential influx of nutrients through spatial gradients. I used these spatial gradients to study how environmental changes might affect microbial community structure and functional capacity in Arctic lakes. I performed a metagenomic analysis of microbial communities from hydrological regimes representing high, low, and negligible influence of glacial runoff and compared the observed structure and function to the natural geochemical gradients. Genes and reconstructed genomes found in different abundances across these sites suggest that high-runoff regimes alter geochemical gradients, homogenise the microbial structure, and reduce genetic diversity. This work shows how a genome-centric metagenomics approach can be used to predict future microbial responses to a changing climate.
A spread spectrum modem for use on electrical power lines
Creators: name: Van Der Gracht, Peter Kenneth
Publisher: name: University of British Columbia
Year: 2010

description: The design, implementation, and testing of a spread spectrum modem for use on electrical power lines are described in this thesis. It is shown that for data communication over power lines, spread spectrum signalling has performance advantages over signalling formats which use a narrow frequency band. Synchronization for the modem is based on the 60 Hz power line signal and significantly reduces the complexity of the modem. A spread spectrum transmitter and receiver are implemented and performance results on some representative power line circuits are presented. The modem performed well and appears to be a viable candidate for data communications over power lines.
An investigation into the effectiveness of diagnostic-prescriptive instruction, using the early prevention of school failure program as a model

description: The effect of specific preschool programs on the development of reading readiness, perceptual-motor, language and cognitive skills has been studied by a number of investigators. The majority of the studies reviewed indicated a positive effect on reading readiness, IQ and the development of prerequisite skills. The purpose of this investigation was to determine the effect of diagnostic-prescriptive instruction on the development of prerequisite skills and reading readiness, using the Early Prevention of School Failure Program as a model. The major components of this program are screening, diagnosis of the screening results, individual learning profiles based on the screening results, prescriptions to strengthen weak areas, and parent involvement. Five treatment levels were included in the present study: (1) diagnostic-prescriptive instruction and parent involvement; (2) diagnostic-prescriptive instruction; (3) an attention placebo to control for a possible Hawthorne effect; (4) learning profiles given to the teachers of one group without the benefit of further suggestions or instruction; (5) the control group. The population was defined as "moderate and high risk" children in kindergarten in the Coquitlam school district. The sample was drawn from 21 half-day kindergarten classes situated in 9 schools of the same district. The final sample consisted of 140 "moderate and high risk" children. The investigator assumed the role of a learning assistance teacher and provided the treatment for groups 1 and 2 once a week. The duration of the treatment was 4 months. Six months elapsed between pre-tests and post-tests. An analysis of covariance was conducted on the Peabody Picture Vocabulary Test, Preschool Language Scale and Beery Developmental Test of Visual-Motor Integration with the pre-tests as a covariate. An analysis of variance was conducted on the Lee Clark Reading Readiness Test. There was no significant treatment effect on the prerequisite skills measured by the Peabody Picture Vocabulary Test, nor was there a treatment effect on reading readiness as measured by the Lee Clark Reading Readiness Test. However, results indicated a positive effect of diagnostic-prescriptive instruction on the development of prerequisite skills measured by the Preschool Language Scale and the Beery Developmental Test of Visual-Motor Integration. In addition, the latter test showed that, without intervention, the discrepancy between mental age and chronological age tended to perpetuate. Therefore it was recommended that school districts implement an early intervention program at the beginning of the kindergarten year. Limitations of the study were noted and suggestions for future research included the establishment of a more reliable and valid screening battery, as well as the establishment of local norms.

description: We present a new joint analysis of pulsar dispersion measures and diffuse H-alpha emission in the Milky Way, which we use to derive the density, pressure and filling factor of the thick disk component of the warm ionised medium (WIM) as a function of height above the Galactic disk. By excluding sightlines at low Galactic latitude that are contaminated by HII regions and spiral arms, we find that the exponential scale-height of free electrons in the diffuse WIM is 1830 (+120, -250) pc, a factor of two larger than has been derived in previous studies. The corresponding inconsistent scale heights for dispersion measure and emission measure imply that the vertical profiles of mass and pressure in the WIM are decoupled, and that the filling factor of WIM clouds is a geometric response to the competing environmental influences of thermal and non-thermal processes. Extrapolating the properties of the thick-disk WIM to mid-plane, we infer a volume-averaged electron density 0.014 +- 0.001 cm^-3, produced by clouds of typical electron density 0.34 +- 0.06 cm^-3 with a volume filling factor 0.04 +- 0.01. As one moves off the plane, the filling factor increases to a maximum of ~30% at a height of approximately 1-1.5 kpc, before then declining to accommodate the increasing presence of hot, coronal gas. Since models for the WIM with a ~1 kpc scale-height have been widely used to estimate distances to radio pulsars, our revised parameters suggest that the distances to many high-latitude pulsars have been substantially underestimated.

How can the nucleus be lighter than its constituents?

Publisher: name: arXiv
Year: 2021
Subjects: subject: Popular Physics (physics.pop-ph)
subject: FOS: Physical sciences

description: The fact that the nucleus is lighter than its constituents, seems rather strange. How can the whole have a smaller mass than its components? To get some intuition about how this is possible, one can look at a simpler more familiar system exhibiting the same phenomena; the hydrogen atom. It turns out that the same is true here; the hydrogen atom is a little bit lighter than the sum of its constituents. This difference corresponds to the ionisation energy of hydrogen. This observation allows a simple explanation for how this is possible; the destructive interference between the electric fields of the proton and electron causes a reduction in the energy of the electric field and hence a reduction in the contribution to the mass of the system from the electric field energy. The same explanation can be extended to the nucleus, thus giving some intuition about how this mass reduction happens. In the process, the idea of classical particles being ball-like objects with localised properties, is challenged.

description: We present a complete set of new flavour-permutation-symmetric mixing observables. We give expressions for these "plaquette invariants", both in terms of the mixing matrix elements alone, and in terms of manifestly Jarlskog-invariant functions of fermion mass matrices. While these quantities are unconstrained in the Standard Model, we point out that remarkably, in the case of leptonic mixing, the values of most of them are consistent with zero, corresponding to certain phenomenological symmetries. We give examples of their application to the flavour-symmetric description of both lepton and quark mixings, showing for the first time how to construct explicitly weak-basis invariant constraints on the mass matrices, for a number of phenomenologically valid mixing ansatze.

A QCD motivated model for soft interactions at high energies

description: In this paper we develop an approach to soft scattering processes at high energies,which is based on two mechanisms: Good-Walker mechanism for low mass diffractionand multi-Pomeron interactions for high mass diffraction. The pricipal idea, that allows us to specify the theory for Pomeron interactions, is that the so called soft processes occur at rather short distances ($r^2 \propto 1 /^2 \propto α'_\pom \approx 0.01 GeV^{-2}$), where perturbative QCD is valid. The value of the Pomeron slope $α'_\pom $ was obtained from the fit to experimental data. Using this theoretical approach we suggest a model that fits all soft data in the ISR-Tevatron energy range, the total, elastic, single and double diffractive cross sections, including $t$ dependence of the differential elastic cross section, and the mass dependence of single diffraction. In this model we calculate the survival probability of diffractive Higgs production, and obtained a value for this observable, which is smaller than 1% at the LHC energy range.

description: In this study, we numerically investigate the internal structure of localized quantum turbulence in superfluid $^4$He at zero temperature with the expectation of self-similarity in the real space. In our previous study, we collected the statistics of vortex rings emitted from a localized vortex tangle. As a result, the power law between the minimum size of detectable vortex rings and the emission frequency is obtained, which suggests that the vortex tangle has self-similarity in the real space [Nakagawa $et$ $al.$, Phys. Rev. B $\boldsymbol{101}$, 184515 (2020)]. In this work, we study the fractal dimension and vortex length distribution of localized vortex tangles, which can show their self-similar structure. We generate statistically steady and localized vortex tangles by injecting vortex rings with a fixed size. We used two types of injection methods that produce anisotropic or isotropic tangles. The injected vortex rings develop into a localized vortex tangle consisting of vortex rings of various sizes through reconnections (fusions and splitting of vortices). The fractal dimension is an increasing function of the vortex line density and becomes saturated to a value of approximately 1.8, as the density increases sufficiently. The behavior of the fractal dimension was independent of the anisotropy of the vortex tangles. The vortex length distribution indicates the number of vortex rings of each size that are distributed in a tangle. The distribution of the anisotropic vortex tangle shows the power law in the range above the injected vortex size, although the distribution of the isotropic vortex does not.

Measuring lifecycle inequality
Creators: name: Blewett, Edwin
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis, theoretically sound and empirically tractable solutions are provided to problems inherent in the traditional practice of measuring inequality in the distribution of annual income. Inequality is taken throughout to mean the extent to which society falls short of a situation in which everyone is equally well-off. The measurement of annual income inequality is inappropriate in this regard because it is consumption, not income, that produces welfare. Furthermore, individual, and therefore social, welfare depends on consumption over the lifecycle, not just in a single year. There are also problems of a less theoretical nature. Measured annual inequality includes an age-related component attributable to the shape of lifecycle income profiles. Annual inequality indices also fail to account for the effects of income mobility. In response to these problems, two new approaches to the measurement of inequality are proposed. In the welfare approach, an improved index of inequality is sought by replacing annual income with a summary statistic of lifecycle consumption. Lifecycle inequality is then decomposed within and among age-cohorts. Intercohort inequality captures the contribution of economic growth to total inequality, while intracohort inequality is an index of pure interpersonal inequality. The decomposition approach is a compromise between the inadequacy of measuring annual income inequality and the impossibility of measuring lifecycle consumption inequality. Total inequality is measured in panel consumption data treated as a single distribution, and then decomposed into indices of age-related, mobility-related, and pure interpersonal inequality. Empirical implementation of the decomposition approach indicates that age-, and especially mobility-related, inequality account for substantial portions of total measured inequality. Sensitivity tests of the decomposition approach indicate that it is a robust method of measuring inequality. Finally, the decomposition approach is applied to the problem of measuring the trend of inequality, widely observed to have been remarkably constant in the post-War period. Although the trend of measured annual inequality is constant, lifecycle inequality as measured using the decomposition approach declines over the sample period. The principal finding of this thesis is that the decomposition approach to the measurement of inequality is essential for an accurate assessment of the level and trend of pure interpersonal inequality.

description: Layered lead halide A'2An-1PbnI3n+1 perovskites (2D LHPs) are attracting considerable attention as a more stable alternative with respect to APbI3 parent phases - a promising material for a new generation of solar cells. However, a critical analysis on the photostability of 2D perovskites homologous row is still lacking. In this work, we perform a comparative study of BA2MAn-1PbnI3n+1 (BA - butylammonium, MA - methylammonium) 2D LHPs with different layer number n = 1-3, considered as study-case systems, and MAPbI3, as a reference. We discuss a stability testing protocol with general validity, comparing photometrical determination of iodine-containing products in nonpolar solvents, X-ray diffraction, and photoluminescence spectroscopy. The resulting photostability trends in inert atmosphere demonstrate a nonmonotonic dependence of degradation rate on the perovskite layer thickness n with a "stability island" at n > 3 which is caused by a combination of antibate factors of electronic structure and chemical composition in the family of 2D perovskites. We also identify a critical oxygen concentration in the surrounding environment that affects the mechanism and strongly enhances the rate of layered perovskites photodegradation.

description: In the context of the recent interest in solvable models of scattering mediated by non-Hermitian Hamiltonians (cf. H. F. Jones, Phys. Rev. D 76, 125003 (2007)) we show that and how the well known variability of our ad hoc choice of the metric $Θ$ which defines the physical Hilbert space of states can help us to clarify several apparent paradoxes. We argue that with a suitable $Θ$ a fully plausible physical picture of the scattering is recovered. Quantitatively, our new recipe is illustrated on an exactly solvable toy model.

description: A path to lowering the economic barrier associated with the high cost of metal additively manufactured components is to reduce the waste via powder reuse (powder cycled back into the process) and recycling (powder chemically, physically, or thermally processed to recover the original properties) strategies. In electron beam powder bed fusion, there is a possibility of reusing 95 - 98% of the powder that is not melted. However, there is a lack of systematic studies focusing on quantifying the variation of powder properties induced by number of reuse cycles. This work compares the influence of multiple reuse cycles, as well as powder blends created from reused powder, on various powder characteristics such as the morphology, size distribution, flow properties, packing properties and chemical composition (oxygen and nitrogen content). It was found that there is an increase in measured response in powder size distribution, tapped density, Hausner ratio, Carr index, basic flow energy and specific energy, dynamic angle of repose, oxygen, and nitrogen content, while the bulk density remained largely unchanged.

Density Dependence of the Mass Function of Globular Star Clusters in the Sombrero Galaxy and its Dynamical Implications

description: We have constructed the mass function of globular star clusters in the Sombrero galaxy in bins of different internal half-mass density rho_h and projected galactocentric distance R. This is based on the published measurements of the magnitudes and effective radii of the clusters by Spitler et al. (2006) in BVR images taken with the ACS on HST. We find that the peak of the mass function M_p increases with rho_h by a factor of about 4 but remains nearly constant with R. Our results are almost identical to those presented recently by McLaughlin & Fall (2007) for globular clusters in the Milky Way. The mass functions in both galaxies agree with a simple, approximate model in which the clusters form with a Schechter initial mass function and evolve subsequently by stellar escape driven by internal two-body relaxation. These findings therefore undermine recent claims that the present peak of the mass function of globular clusters must have been built into the initial conditions.

description: We provide sensitivity comparisons for two competing versions of the dimension reduction method principal Hessian directions (pHd). These comparisons consider the effects of small perturbations on the estimation of the dimension reduction subspace via the influence function. We show that the two versions of pHd can behave completely differently in the presence of certain observational types. Our results also provide evidence that outliers in the traditional sense may or may not be highly influential in practice. Since influential observations may lurk within otherwise typical data, we consider the influence function in the empirical setting for the efficient detection of influential observations in practice.

This framework depends on two novel resources we develop in the course of this work: a very large-scale collection of English sentences expressing causal patterns CausalBank; and a refinement over previous work on constructing large lexical causal knowledge graphs Cause Effect Graph. Further, we extend prior work in lexically-constrained decoding to support disjunctive positive constraints. Human assessment confirms that our approach gives high-quality and diverse outputs. Finally, we use CausalBank to perform continued training of an encoder supporting a recent state-of-the-art model for causal reasoning, leading to a 3-point improvement on the COPA challenge set, with no change in model architecture.

Using the $q^2$ dependencies of the relevant form factors, the total decay width and the branching ratio for these decays are also evaluated. A comparison of our results for the form factors of $B\to D\ellν$ with the lattice QCD predictions within heavy quark effective theory and zero recoil limit is presented. Our results of the branching ratio are in good agreement with the constituent quark meson model for ($q=s, u, d$) and experiment for ($q= u, d$). The result of branching ratio for $B_{s}\to D_{s}(1968)\ellν$ indicates that this transition can also be detected at LHC in the near future.

description: Mesh numbering is a critical issue in Finite Element Methods, as the computational cost of one analysis is highly dependent on the order of the nodes of the mesh. This paper presents some preliminary investigations on the problem of mesh numbering using Evolutionary Algorithms. Three conclusions can be drawn from these experiments. First, the results of the up-to-date method used in all FEM softwares (Gibb's method) can be consistently improved; second, none of the crossover operators tried so far (either general or problem specific) proved useful; third, though the general tendency in Evolutionary Computation seems to be the hybridization with other methods (deterministic or heuristic), none of the presented attempt did encounter any success yet. The good news, however, is that this algorithm allows an improvement over the standard heuristic method between 12% and 20% for both the 1545 and 5453-nodes meshes used as test-bed. Finally, some strange interaction between the selection scheme and the use of problem specific mutation operator was observed, which appeals for further investigation.

description: It has long remained elusive whether CuCo$_{2}$S$_{4}$ thiospinel shows bulk superconductivity. Here we clarify the issue by studying on the samples of sulfur-deficient CuCo$_{2}$S$_{3.7}$ and sulfurized CuCo$_{2}$S$_{4}$. The sample CuCo$_{2}$S$_{3.7}$ has a smaller lattice constant of $a=9.454$ Å, and it is not superconducting down to 1.8 K. After a full sulfurization, the $a$ axis of the thiospinel phase increases to 9.475 Å, and the thiospinel becomes nearly stoichiometric CuCo$_{2}$S$_{4}$, although a secondary phase of slightly Cu-doped CoS$_2$ forms. Bulk superconductivity at 4.2 K and Pauli paramagnetism have been demonstrated for the sulfurized CuCo$_{2}$S$_{4}$ by the measurements of electrical resistivity, magnetic susceptibility, and specific heat.

description: The eSMA ("extended SMA") combines the SMA, JCMT and CSO into a single facility, providing enhanced sensitivity and spatial resolution owing to the increased collecting area at the longest baselines. Until ALMA early science observing (2011), the eSMA will be the facility capable of the highest angular resolution observations at 345 GHz. The gain in sensitivity and resolution will bring new insights in a variety of fields, such as protoplanetary/transition disks, high-mass star formation, solar system bodies, nearby and high-z galaxies. Therefore the eSMA is an important facility to prepare the grounds for ALMA and train scientists in the techniques. Over the last two years, and especially since November 2006, there has been substantial progress toward making the eSMA into a working interferometer. In particular, (i) new 345-GHz receivers, that match the capabilities of the SMA system, were installed at the JCMT and CSO; (ii) numerous tests have been performed for receiver, correlator and baseline calibrations in order to determine and take into account the effects arising from the differences between the three types of antennas; (iii) first fringes at 345 GHz were obtained on August 30 2007, and the array has entered the science-verification stage. We report on the characteristics of the eSMA and its measured performance at 230 GHz and that expected at 345 GHz. We also present the results of the commissioning and some initial science-verification observations, including the first absorption measurement of the C/CO ratio in a galaxy at z=0.89, located along the line of sight to the lensed quasar PKS1830-211, and on the imaging of the vibrationally excited HCN line towards IRC+10216.

description: Electromyogram (EMG) has been utilized to interface signals for prosthetic hands and information devices owing to its ability to reflect human motion intentions. Although various EMG classification methods have been introduced into EMG-based control systems, they do not fully consider the stochastic characteristics of EMG signals. This paper proposes an EMG pattern classification method incorporating a scale mixture-based generative model. A scale mixture model is a stochastic EMG model in which the EMG variance is considered as a random variable, enabling the representation of uncertainty in the variance. This model is extended in this study and utilized for EMG pattern classification. The proposed method is trained by variational Bayesian learning, thereby allowing the automatic determination of the model complexity. Furthermore, to optimize the hyperparameters of the proposed method with a partial discriminative approach, a mutual information-based determination method is introduced. Simulation and EMG analysis experiments demonstrated the relationship between the hyperparameters and classification accuracy of the proposed method as well as the validity of the proposed method. The comparison using public EMG datasets revealed that the proposed method outperformed the various conventional classifiers. These results indicated the validity of the proposed method and its applicability to EMG-based control systems. In EMG pattern recognition, a classifier based on a generative model that reflects the stochastic characteristics of EMG signals can outperform the conventional general-purpose classifier.

description: In an earlier work [1] J. Suzuki proposed a set of nonlinear integral equations (NLIE) to describe the excited state spectrum of the integrable spin-1 XXZ chain in its repulsive regime. In this paper we extend his equations for the attractive regime of the model, and calculate analytically the conformal spectrum of the spin chain. We also discuss the typical root configurations of the thermodynamic limit as well as the 2-string deviations of certain excited states of the model. Special objects appearing in the NLIE are also treated with special care.

description: We report the Ni-doping effect on magnetism and superconductivity (SC) in an Eu-containing 112-type system Eu(Fe$_{1-x}$Ni$_{x})$As$_{2}$ ($0\leq x\leq 0.15$) by the measurements of resistivity, magnetization, and specific heat. The undoped EuFeAs$_2$ undergoes a spin-density-wave (SDW) transition at $T_\mathrm{SDW}\sim$ 105 K in the Fe sublattice and a magnetic ordering at $T_\mathrm{m}\sim$ 40 K in the Eu sublattice. Complex Eu-spin magnetism is manifested by a spin-glass reentrance at $T_\mathrm{SG}\sim$ 15 K and an additional spin reorientation at $T_\mathrm{SR}\sim$ 7 K. With Ni doping, the SDW order is rapidly suppressed, and SC emerges in the Ni-doping range of 0.01 $\leq x\leq$ 0.1 where a maximum of the superconducting transition temperature $T_\mathrm{c}^{\mathrm{max}}=$ 17.6 K shows up at $x$ = 0.04. On the other hand, $T_\mathrm{m}$ decreases very slowly, yet $T_\mathrm{SG}$ and $T_\mathrm{SR}$ hardly change with the Ni doping. The phase diagram has been established, which suggests a very weak coupling between SC and Eu spins. The complex Eu-spin magnetism is discussed in terms of the Ruderman-Kittel-Kasuya-Yosida interactions mediated by the conduction electrons from both layers of FeAs and As surrounding Eu$^{2+}$ ions.

description: Photon echo is a fundamental tool for the manipulation of electromagnetic fields. Unavoidable spontaneous emission noise is generated in this process due to the strong rephasing pulse, which limits the achievable signal-to-noise ratio and represents a fundamental obstacle towards their applications in the quantum regime. Here we propose a noiseless photon-echo protocol based on a four-level atomic system. We implement this protocol in a Eu3+:Y2SiO5bcrystal to serve as an optical quantum memory. A storage fidelity of 0.952 is obtained for time-bin qubits encoded with single-photon-level coherent pulses, which is far beyond the maximal fidelity achievable using the classical measure-and-prepare strategy. In this work, the demonstrated noiseless photon-echo quantum memory features spin-wave storage, easy operation and high storage fidelity, which should be easily extended to other physical systems.
Serine tRNAs and their genes in Drosophila melanogaster
Creators: name: Cribbs, David Lamar
Publisher: name: University of British Columbia

description: Serine tRNAs and their genes in Drosophila melanogaster were characterized. The nucleotide sequences of tRNA₄[sup=Ser] (codon UCG), tRNA₇[sup=Ser] (UCA, UCC, UCU), and tRNA[sub=2b][sup=Ser] (AGC, AGU) were determined. Also, the nucleotide sequences of four tRNA[sup=Ser] genes from the X chromosome isolated in recombinant plasmids were determined. Transfer RNA₄[sup=Ser] and tRNA₇[sup=Ser] differ at only three out of 85 positions, including the "wobble" nucleotide of the anticodon. However, tRNA[sub=2b][sup=Ser] is only 72% homologous with tRNA₄[sup=Ser] (62 out of 85 positions, not counting differences in modification). Major regions of sequence homology (> 5 consecutive positions) are found only in the D arm (21 consecutive positions) and in the TѱC arm (11 consecutive positions). Transfer RNA₄[sup=Ser] and tRNA₇[sup=Ser] are indistinguishable by RNA-DNA hybridization. Both hybridize to the same sites on polytene chromosomes in situ, including the major site at 12DE on the X chromosome, and 23E on chromosome 2 (Hayashi et al. (1980). Chromosoma 76, 65-84.) No other purified tRNA than tRNAs[sub=4,7][sup=Ser] has been shown to hybridize to the X chromosome in Drosophila. Therefore, several X-derived recombinant plasmids hybridizing tRNA[sub=4,7][sup=Ser] (pDt 16, pDt 17R, pDt 27R, and pDt 73; Dunn et al. (1979). Gene ], 197-215.) were analyzed. Based on the results of Southern blotting experi-ments, there appear to be eight tRNA[sup=Ser] genes on the four plasmids (one each on pDt 17R and pDt 73; two on pDt 16; and four on pDt 27R). Thus, the 12DE region contains at least eight tRNA[sup=Ser] genes. Restriction mapping and DNA sequence analysis were performed with pDt 16, pDt 17R, and pDt 73. Based on the tRNA sequences, which differ at three positions, the presumptive DNA sequences encoding tRNA[sub=4] [sup=Ser] and tRNA[sub=7] [sup=Ser] can be represented as 444 or 777 genes. DNA sequence analysis gave surprising Ser results in this respect. Analysis of four tRNA[sup=Ser] genes on the three plasmids S identified two 777 genes matching tRNA₇[sup=Ser] plus "hybrid" 774 and 474 sequences. Further, pDt 16 contains both a 777 and a 774 gene as a direct repeat 400 Ser base pairs apart. Since a 444 gene corresponding to tRNA₄[sup=Ser] must exist, there are at least four different types of closely related serine tRNA genes in the D. melanogaster genome. This observation may have implications concerning the evolution and maintenance of reiterated tRNA genes in eukaryotes. In addition to studies on serine tRNAs and their genes, the nucleotide sequences of Drosophila tRNA₅[sup=Lys] and of a tRNA[sup=Arg] were determined.
