description: For a class of coupled limit cycle oscillators, we give a condition on a linear coupling operator that is necessary and sufficient for exponential stability of the synchronous solution. We show that with certain modifications our method of analysis applies to networks with partial, time-dependent, and nonlinear coupling schemes, as well as to ensembles of local systems with nonperiodic attractors. We also study robustness of synchrony to noise. To this end, we analytically estimate the degree of coherence of the network oscillations in the presence of noise. Our estimate of coherence highlights the main ingredients of stochastic stability of the synchronous regime. In particular, it quantifies the contribution of the network topology. The estimate of coherence for the randomly perturbed network can be used as means for analytic inference of degree of stability of the synchronous solution of the unperturbed deterministic network. Furthermore, we show that in large networks, the effects of noise on the dynamics of each oscillator can be effectively controlled by varying the strength of coupling, which provides a powerful mechanism of denoising. This suggests that the organization of oscillators in a coupled network may play an important role in maintaining robust oscillations in random environment. The analysis is complemented with the results of numerical simulations of a neuronal network.

description: There is an increasing interest in alternatives to peat in growing media due to environmental constraints. However, plants grown in peat substitutes often show impaired growth compared to plants grown in peat-based media. Hence, it would be interesting to know whether these deficiencies can be compensated by supplementing other growth factors, e.g. light. The present study aims to investigate the interactive nature between growing media and supplemental lighting on plant growth and morphology, and to examine whether supplemental light emitting diode (LED) lighting may compensate adverse growing media effects. Basil (Ocimum basilicum L.) and Chinese cabbage (Brassica rapa subsp. pekinensis) were grown in different growing media consisting of peat, green compost, coconut pulp, wood fibre, perlite and sphagnum moss under blue, red and far-red supplemental LED lighting. We found significant interactions between growing media and supplemental photosynthetically active radiation (PAR) on plant growth, morphology and development. At low light intensities, peat-based and substituted growing media performed similarly, whereas with increasing light intensities the peat-based growing media significantly outperformed their alternatives. The substrate choice determines the required amount of supplemental light to compensate for adverse growing media effects and the amount varies depending on plant species and season. Thereby, it was indicated that red light alleviates adverse growing media effects best. We also found that far-red light is not effective when background PAR is low and becomes more effective under high background PAR. The implications and prospects of the results are discussed.

description: In December 2019, in Wuhan, an outbreak of a new coronavirus (SARS-CoV-2) began to spread rapidly, resulting in a potentially fatal viral respiratory disease. Since August 23, 2020, more than 679 million cases of COVID-19 and nearly 6.8 million deaths have been confirmed in more than 200 countries. This, in turn, had a severe impact on public health and the world economy. The SARS-CoV-2 pandemic also resulted in a shortage of viral transport medium and in the need to find different diagnostic means, such as saliva. To fill this gap in the market, a new viral transport medium was created and tested with samples collected from the nasopharynx and/or oropharynx using swabs and saliva samples. The specificity, sensitivity, and threshold cycles (Cts) of Real-Time PCR (RT-PCR) testing of the samples were compared, revealing concordant results with approximate sensitivity and specificity. Our study highlighted the need to optimize saliva sample collection and its potential use as a substitute for standard collection.

description: We study the capabilities of future electron-positron Linear Colliders, with centre-of-mass energy at the TeV scale, in accessing the parameter space of a $Z'$ boson within the minimal $B-L$ model. We carry out a detailed comparison between the discovery regions mapped over a two-dimensional configuration space ($Z'$ mass and coupling) at the Large Hadron Collider and possible future Linear Colliders for the case of di-muon production. As known in the literature for other $Z'$ models, we confirm that leptonic machines, as compared to the CERN hadronic accelerator, display an additional potential in discovering a $Z'$ boson as well as in allowing one to study its properties at a level of precision well beyond that of any of the existing colliders.

subject: FOS: Physical sciences

description: The one-dimensional Schrödinger equation with the point potential in the form of the derivative of Dirac's delta function, $λδ'(x)$ with $λ$ being a coupling constant, is investigated. This equation is known to require an extension to the space of wave functions $ψ(x)$ discontinuous at the origin under the two-sided (at $x=\pm 0$) boundary conditions given through the transfer matrix ${cc} {\cal A} 0 0 {\cal A}^{-1})$ where ${\cal A} = {2+λ\over 2-λ}$. However, the recent studies, where a resonant non-zero transmission across this potential has been established to occur on discrete sets $\{λ_n \}_{n=1}^\infty$ in the $λ$-space, contradict to these boundary conditions used widely by many authors. The present communication aims at solving this discrepancy using a more general form of boundary conditions.

title: The role of the hypothalamus-pituitary-thyroid axis in appetite regulation of goldfish (Carassius auratus)
Creators: name: Deal, Cole K.
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: This thesis aimed to understand the role that the hypothalamus-pituitary-thyroid (HPT) axis plays in appetite regulation of goldfish (Carassius auratus). I altered nutritional and thyroid statuses to measure the response of thyroid axis components and appetite-regulating peptides. I predicted that fasting would downregulate the thyroid axis and trigger an orexigenic response, while overfeeding would upregulate the thyroid axis and trigger an anorexigenic response. Additionally, I predicted that hyperthyroid conditions would lead to negative feedback of the thyroid axis and an orexigenic response, whilst opposite under hypothyroid conditions. I uncovered for both experiments that the thyroid axis in goldish is most responsive to overfeeding and hyperthyroidism. Overfeeding led to a time-dependent increase in central thyroid transcripts while fasting decreased thyroid hormone degradation peripherally with no central response, no treatment altered levels of thyroid hormone in circulation. Hyperthyroidism resulted in negative feedback to the pituitary, but not hypothalamus, and did not lead to an increase in food intake despite an increase in the levels of thyroxine. The thyroid inhibitor, propylthiouracil, did not induce hypothyroidism or alter the expression of any thyroid axis transcript. Appetite-regulating peptides correlated weakly to changes in the thyroid, suggesting an overall poor association in goldfish between appetite regulation and thyroid status.

description: Within the framework of non-local quark model of Nambu--Jona-Lasinio type the two-photon decay of radial excited state of $π_0$-meson -- $π_0'$ -- is found to be $3.6\KeV$. The radial excitation of pion is described with the use of polynomial formfactor of second order over $\vec q^2$ where $\vec q$ is the transverse momentum, which corresponds to relative motion of quark-antiquark pair within the energy range from 0 up to $1\GeV$. The probabilities of production of $π_0'$ and $(π_0'+γ)$ states in the electron-positron colliders are estimated. The production of $π_0'$-meson in the interaction of photon with electron or muon is as well considered (Primakoff effect). The relevant total cross sections are 0.14 or $0.06\nb$.

description: Airway organoids derived from adult murine epithelial cells represent a complex 3D in vitro system mimicking the airway epithelial tissue’s native cell composition and physiological properties. In combination with a precise damage induction via femtosecond laser-based nanosurgery, this model might allow for the examination of intra- and intercellular dynamics in the course of repair processes with a high spatio-temporal resolution, which can hardly be reached using in vivo approaches. For characterization of the organoids’ response to single or multiple-cell ablation, we first analyzed overall organoid survival and found that airway organoids were capable of efficiently repairing damage induced by femtosecond laser-based ablation of a single to ten cells within 24 h. An EdU staining assay further revealed a steady proliferative potential of airway organoid cells. Especially in the case of ablation of five cells, proliferation was enhanced within the first 4 h upon damage induction, whereas ablation of ten cells was followed by a slight decrease in proliferation within this time frame. Analyzing individual trajectories of single cells within airway organoids, we found an increased migratory behavior in cells within close proximity to the ablation site following the ablation of ten, but not five cells. Bulk RNA sequencing and subsequent enrichment analysis revealed the differential expression of sets of genes involved in the regulation of epithelial repair, distinct signaling pathway activities such as Notch signaling, as well as cell migration after laser-based ablation. Together, our findings demonstrate that organoid repair upon ablation of ten cells involves key processes by which native airway epithelial wound healing is regulated. This marks the herein presented in vitro damage model suitable to study repair processes following localized airway injury, thereby posing a novel approach to gain insights into the mechanisms driving epithelial repair on a single-cell level.

Reframing a sense of self: a constructivist grounded theory study of children's admission to hospital for surgery
Creators: name: Ford, K
Publisher: name: University Of Tasmania
Year: 2023

description: Children are significant users of healthcare and their needs are different to those of adults. Whilst important gains have been made in children's hospital care since the last half of the 20th century, there is a recent trend to reduce dedicated paediatric services in Australia. In order to provide healthcare services that are child centred and that truly respond to the needs of children, children's perspectives on their healthcare are essential. Yet the inclusion of children's perspectives in health services and research is lacking. It is through listening to, and hearing children, that health care can move closer to meeting their needs. This qualitative study explored the experiences of 10 primary school aged children (six to twelve years of age) admitted to hospital for surgery, from their perspective. A constructivist grounded theory approach was used that incorporated flexible, child centred research techniques including interviews and the 'draw and write technique'. This thesis presents a substantive theory: children's reframing of their sense of selves to incorporate the experiences of hospitalisation and surgery. The children were active participants embedded within the phenomenon. Admission to hospital for surgery presented a form of adversity for the children in what was an embodied experience of contrasts. Major concepts of the experience were: 'being scared'; 'hurting'; and 'having fun'. There were two major processes the children engaged in for reframing their sense of self to incorporate the experience. The first was around their meaning making activities, expressed as 'coming to know' and the second was their ability to move on from the adversity and reintegrate the experience into their normal lives, expressed as 'bouncing back'. In order for the children to successfully incorporate the experience into their sense of self, a supportive context or holding environment was necessary, expressed as 'being held'. Children were the primary source of knowledge about their views and experiences for this study. The findings highlight the importance of centring children's healthcare on the needs of children and their families. The findings suggest that ongoing problems with paediatric practices continue to impact negatively on children's experiences of hospitalisation. Although there is a body of evidence about what constitutes best practice, in reality, practices fall short of these recommendations.
Adolescence, sense of identity and risk taking amongst female students in a senior secondary school in Tasmania
Creators: name: Wood, D
Publisher: name: University Of Tasmania
Year: 2023

description: This research examined risk taking, with the main focus being negative risk taking and the main target adolescent females in a Senior Secondary School setting in Tasmania, using three varied methodologies and perspectives for the data collection. The first, and major method, used a questionnaire distributed to a Year 11 group of females, aged sixteen to nineteen, who were just beginning their first year of non ‚Äö-compulsory, post secondary education. This questionnaire covered many socio-demographic factors in the females' lives and had the main focus of discovering their risk taking perceptions and participation rates regarding four main areas of negative risk taking, namely alcohol and drug use and abuse, sexual activity and the viewing of X-Rated (pornographic) videos. The socio-demographic information concentrated on the females' sense of self, their personal goals and positive and negative risk taking activities within the context of social capital, psychological, social, educational, risk taking and health background theory and in the three domains of family, school and community. Comparisons were drawn between the town and country female participants. To provide a wider perspective on the topic of risk taking, interviews were also conducted with those professionals and carers of adolescent children, namely School Administrators, Teachers, and Parents to provide information from the reality of adolescents' lives. These adults gave important insights into the actual issues, common to this age group. They provided information regarding the nature of their discussions about risk- taking and the strategies they utilized to produce resilience in adolescents and the avoidance of negative risk-taking activities. The third source of data involved a review of the Australian and State Policies impinging on aspects of the curricula suitable for these adolescents. These policies demonstrated two approaches to the topics under discussion in this thesis. The Australian Government policies gave broad, generic guidelines to the problems associated with negative risk taking and provided funding, whilst the individual States provided the actual curricula and personnel. Funding was a key component for the successful implementation of the State programs. The major findings from the questionnaire emphasised that the females' sense of self, parental influence and, to a lesser extent, religious values will decrease negative risk taking. The advice from the adults in the interviews focused on maintaining a positive attitude about adolescent risk taking activities, with the use of personal experiences to provide guidelines for appropriate behaviour. The analysis of the policies emphasised the need to provide healthy, supportive environments for adolescents and appropriate information about negative risk taking.

description: Continuous generating grinding processes have largely replaced discontinuous profile grinding processes in gear manufacturing due to their higher productivity. On order to transfer the advantage of the productivity benefits of this process to tool grinding, the continuous generating grinding was adapted to the manufacture of cutting tools. However, this novel approach of using continuous generating grinding processes for tool grinding has not been widely investigated. Therefore, the aim of this study is to investigate the influence of cutting speed, feed and radial depth of cut on the process result and thus to generate initial knowledge for the process design. Subsequently, the influence of these parameters on the grinding worm wear as well as on the cutting edge quality and surface properties of the ground milling tools are investigated. The results show that an increase of the radial depth of cut leads to a reduction of the process time by the factor of four without significantly influencing the wear of the grinding worm tooth. Furthermore, an increase of the cutting speed only leads to an increase in the initial wear of the grinding worm after the dressing process. For this reason, the cutting speed offers the potential to further increase the productivity of the process. The microgeometry of the cutting edge of the ground milling tool is mainly affected by the feed and the macro geometry by the feed and radial depth of cut.

Influence of environmental factors on population structure of Arrow Squid Nototodarus gouldi: Implications for stock assessment
Creators: name: Green, CP
Publisher: name: University Of Tasmania
Year: 2023

description: As separate stocks within a fishery can function differently, ensuring sustainability of each is fundamental when establish or refining management regulations and relies on a firm comprehension of the biological, recruitment, growth, predator-prey, and mortality characteristics in response to environmental factors and fishing pressure. The aim of this study was to analyse the population structure, recruitment variability, migratory characteristics, and catch composition of the arrow squid Nototodarus gouldi collected in the Great Australian Bight (GAB) and Victoria from 2007 ‚Äö- 2009. Nototodarus gouldi is a common oceanic ommastrephid found in waters of southern Australia and are considered commercially and ecologically important. Although research on N. gouldi has already provided biological and population characteristics for fisheries assessments, better estimates of temporal and spatial variability of population structure and the processes responsible are required. Completing their lifecycle in less than one year, N. gouldi exhibited substantial variability in growth, spatial distribution, and recruitment; processes considered to be highly influenced by environment and oceanic factors such as water temperature and productivity. Comparing statolith shape and biological characteristics from squid collected in Victoria to squid collected in the GAB suggested significant phenotypic heterogeneity in stocks; whereas statolith elemental composition analysis indicated that N. gouldi caught at either location hatch throughout their distribution. Both male and female N. gouldi grew faster and were larger in cooler waters off Victoria compared with warmer waters of the GAB. The correlation of sea surface temperature (SST) with growth showed that juveniles experiencing greater SST resulted in slower growth in the GAB; however, juveniles experiencing greater SST had faster growth in Victoria. Distribution of hatch dates calculated from statolith age estimates suggested that N. gouldi collected in Victoria and the GAB during 2007 ‚Äö- 2009 hatch year round with peaks of greater recruitment. Comparing the catch composition of N. gouldi caught inshore from the jig fishery to squid caught offshore from the trawl fishery using measures of size and growth suggested that squid caught inshore by jiggers were larger, consisted of more males than females, and had a greater percentage of mature females. However, statolith elemental composition from N. gouldi collected at inshore and offshore locations was likely to be driven by uniform ocean water chemistry and squid physiological processes. Based on biology, reproductive, recruitment, and growth characteristics of N. gouldi found in southern Australia, current fishing effort is unlikely to jeopardize the sustainability of the resource.

description: The extragalactic background light (EBL) from the far infrared through the visible and extending into the ultraviolet is thought to be dominated by starlight, either through direct emission or through absorption and reradiation by dust. This is the most important energy range for absorbing $\g$-rays from distant sources such as blazars and gamma-ray bursts and producing electron positron pairs. In previous work we presented EBL models in the optical through ultraviolet by consistently taking into account the star formation rate (SFR), initial mass function (IMF) and dust extinction, and treating stars on the main sequence as blackbodies. This technique is extended to include post-main sequence stars and reprocessing of starlight by dust. In our simple model, the total energy absorbed by dust is assumed to be re-emitted as three blackbodies in the infrared, one at 40 K representing warm, large dust grains, one at 70 K representing hot, small dust grains, and one at 450 K representing polycyclic aromatic hydrocarbons. We find our best fit model combining the Hopkins and Beacom SFR using the Cole et al. parameterization with the Baldry and Glazebrook IMF agrees with available luminosity density data at a variety of redshifts. Our resulting EBL energy density is quite close to the lower limits from galaxy counts and in some cases below the lower limits, and agrees fairly well with other recent EBL models shortward of about 5 $μ$m. Deabsorbing TeV $\g$-ray spectra of various blazars with our EBL model gives results consistent with simple shock acceleration theory. We also find that the universe should be optically thin to $\g$-rays with energies less than 20 GeV.

description: We examine the picture of emergent geometry arising from a mass-deformed matrix model. Because of the mass-deformation, a vacuum geometry turns out to be a constant curvature spacetime such as d-dimensional sphere and (anti-)de Sitter spaces. We show that the mass-deformed matrix model giving rise to the constant curvature spacetime can be derived from the d-dimensional Snyder algebra. The emergent geometry beautifully confirms all the rationale inferred from the algebraic point of view that the d-dimensional Snyder algebra is equivalent to the Lorentz algebra in (d+1)-dimensional {\it flat} spacetime. For example, a vacuum geometry of the mass-deformed matrix model is completely described by a G-invariant metric of coset manifolds G/H defined by the Snyder algebra. We also discuss a nonlinear deformation of the Snyder algebra.

description: Compact categories have lately seen renewed interest via applications to quantum physics. Being essentially finite-dimensional, they cannot accomodate (co)limit-based constructions. For example, they cannot capture protocols such as quantum key distribution, that rely on the law of large numbers. To overcome this limitation, we introduce the notion of a compactly accessible category, relying on the extra structure of a factorisation system. This notion allows for infinite dimension while retaining key properties of compact categories: the main technical result is that the choice-of-duals functor on the compact part extends canonically to the whole compactly accessible category. As an example, we model a quantum key distribution protocol and prove its correctness categorically.

The Ecology of the juvenile southern rock lobster, Jasus edwardsii (Hutton 1875) (Palinuridae).
Creators: name: Edmunds, M
Publisher: name: University Of Tasmania
Year: 2023

description: This study examined the life history of juvenile Jasus edwardsii, with a particular emphasis on ontogenetic shifts in ecology, and how these shifts and other ecological factors may influence recruitment rates to maturity and the fishery. The aspects examined included settlement, density and distribution, shelter utilisation and availability, diet, morphology, as well as growth, survival and movement. Shifts in ecology, particularly in dispersion pattems, shelter utilisation and diet were found throughout the juvenile size range. However, a distinct early benthic phase was recognised, with a rapid transition from this phase occurring at approximately 35 mm carapace length (CL). More gradual shifts in ecology occurred after this size. Early benthic phase lobsters were solitary dwellers, randomly to evenly dispersed over the reef and consumed predominantly ophiuroids, isopods and bivalves. In contrast, larger juveniles were gregarious, cohabiting in shelters with conspecifics and having clumped shelter distributions. They also consumed predominantly bivalves, crabs and urchins. These changes corresponded with allometric changes in morphology. Early benthic lobsters had specific shelter requirements compared to the broader range of shelters used by larger lobsters, and were more likely to be affected by limitations in shelter availability. Shelter availability was dependent on the substrate type and structure, but was not found to be limiting during this study. However, settlement rates during this study were low, and shelter may be limiting at higher settlement rates. Intemal microtagging techniques were developed to examine the population dynamics of newly settled lobsters (from 10 mm CL or 0.6 g). The growth of microtagged lobsters released in the wild was seasonal, ranging from a mean of 2.5 mm CL per month in summer to a mean of 1.1 mm CL per month in the winter. The loss rates of tagged lobsters from the study area, due to mortality and emigration, were high and varied between release batches, the probability of survival ranging from a maximum of 51% to less than 1%. Lobsters remaining in the study area had a high fidelity to particular shelters. The results of this study suggest that the early benthic phase is a critical phase in determining recruitment rates to maturity and the fishery, particularly due to the influences of specific shelter requirements, increased susceptibility to predation and variations in growth and survival.

description: It is expected that hadron collider measurements of the Higgs boson mass using the decay h -> W^+W^-, followed by the leptonic decay of each W-boson, will be performed by fitting the shape of a distribution which is sensitive to the Higgs mass. We demonstrate that the variable most commonly used to measure the Higgs mass in this channel is not optimal as it contains an unnecessary and even counter-productive approximation. We remove that approximation, without introducing any cost in complexity, and demonstrate that the new variable is a clear improvement over the old: its performance is never worse, and in some cases (particularly the high Higgs mass region) it might reduce the fit uncertainty on the Higgs mass in that channel by a factor approaching two.

description: We investigate the $D\bar{D}$ production in $e^+e^-$ annihilations near threshold in an effective Lagrangian approach. This shows that the lineshape of the cross section near threshold is sensitive to the contributions from $ψ^\prime$, though it is below the $D\bar{D}$ threshold. The recent experimental data from the BES and Belle collaborations allow us to determine the $ψ^\prime D\bar{D}$ coupling constant which appears to be consistent with other theoretical studies. As a consequence, the $ψ^\prime$-$ψ(3770)$ mixing parameter can be extracted around the $ψ(3770)$ mass region. Resonance parameters for $ψ(3770)$, X(3900), $ψ(4040)$, and $ψ(4160)$ are also investigated. The X(3900) appears as an enhancement at around 3.9 GeV in the Belle data. In addition to treating it as a resonance, we also study the mechanism that the enhancement is produced by the $D\bar{D^*}+c.c.$ open channel effects. Our result shows that such a possibility cannot be eliminated.

description: We study linear cosmological perturbations in a previously introduced family of deformations of general relativity characterized by the absence of new degrees of freedom. The homogeneous and isotropic background in this class of theories is unmodified and is described by the usual Friedmann equations. The theory of cosmological perturbations is modified and the relevant deformation parameter has the dimension of length. Gravitational perturbations of the scalar type can be described by a certain relativistic potential related to the matter perturbations just as in general relativity. A system of differential equations describing the evolution of this potential and of the stress-energy density perturbations is obtained. We find that the evolution of scalar perturbations proceeds with a modified effective time-dependent speed of sound, which, contrary to the case of general relativity, does not vanish even at the matter-dominated stage. In a broad range of values of the length parameter controlling the deformation, a specific transition from the regime of modified gravity to the regime of general relativity in the evolution of scalar perturbations takes place during the radiation domination. In this case, the resulting power spectrum of perturbations in radiation and dark matter is suppressed on the comoving spatial scales that enter the Hubble radius before this transition. We estimate the bounds on the deformation parameter for which this suppression does not lead to observable consequences. Evolution of scalar perturbations at the inflationary stage is modified but very slightly and the primordial spectrum generated during inflation is not noticeably different from the one obtained in general relativity.

description: We analyze the big bounce transition of the quantum FRW model in the setting of the nonstandard loop quantum cosmology (LQC). Elementary observables are used to quantize composite observables. The spectrum of the energy density operator is bounded and continuous. The spectrum of the volume operator is bounded from below and discrete. It has equally distant levels defining a quantum of the volume. The discreteness may imply a foamy structure of spacetime at semiclassical level which may be detected in astro-cosmo observations. The nonstandard LQC method has a free parameter that should be fixed in some way to specify the big bounce transition.

description: Warming in Central Asia has been accelerating over the past three decades and is expected to intensify through the end of this century. Here, we develop a summer temperature reconstruction for western Mongolia spanning eight centuries (1269–2004 C.E.) using delta blue intensity measurements from annual rings of Siberian larch. A significant cooling response is observed in the year following major volcanic events and up to five years post-eruption. Observed summer temperatures since the 1990s are the warmest over the past eight centuries, an observation that is also well captured in Coupled Model Intercomparison Project (CMIP5) climate model simulations. Projections for summer temperature relative to observations suggest further warming of between ∼3°C and 6°C by the end of the century (2075–2099 cf. 1950–2004) under the representative concentration pathways 4.5 and 8.5 (RCP4.5 and RCP8.5) emission scenarios. We conclude that projected future warming lies beyond the range of natural climate variability for the past millennium as estimated by our reconstruction.
The targum (1969:Apr. 1 - 1969:Apr. 30)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1969

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.
Exact Moment Scaling from Multiplicative Noise

description: For a general class of diffusion processes with multiplicative noise, describing a variety of physical as well as financial phenomena, mostly typical of complex systems, we obtain the analytical solution for the moments at all times. We allow for a non trivial time dependence of the microscopic dynamics and we analytically characterize the process evolution, possibly towards a stationary state, and the direct relationship existing between the drift and diffusion coefficients and the time scaling of the moments.

A spherical scalar-tensor galaxy model

description: We build a spherical halo model for galaxies using a general scalar-tensor theory of gravity in its Newtonian limit. The scalar field is described by a time-independent Klein-Gordon equation with a source that is coupled to the standard Poisson equation of Newtonian gravity. Our model, by construction, fits both the observed rotation velocities of stars in spirals and a typical luminosity profile. As a result, the form of the new Newtonian potential, the scalar field, and dark matter distribution in a galaxy are determined. Taking into account the constraints for the fundamental parameters of the theory (lambda,alpha), we analyze the influence of the scalar field in the dark matter distribution, resulting in shallow density profiles in galactic centers.

description: Garoufalidis conjectured a relation between the boundary slopes of a knot and its colored Jones polynomials. According to the conjecture, certain boundary slopes are detected by the sequence of degrees of the colored Jones polynomials. We verify this conjecture for adequate knots, a class that vastly generalizes that of alternating knots.
