The targum (1954:Oct. 1 - 1954:Oct. 29)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1954

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.

description: A switching-off process very similar to those in real high-voltage self-blast circuit-breakers is emulated in a model chamber to study the arc properties by optical emission spectroscopy. The arc is operated in a chamber filled with SF$_6$ between a pin-tulip contact system enclosed by a PTFE nozzle. Transparent windows in the chamber wall and a slit in the nozzle enable an optical investigation of the arc cross section less than one millisecond before current zero. The side-on radiance of a fluorine atom lines has been measured with an imaging spectroscopic system. Considering rotational symmetry of the arc the corresponding radial emission coefficients have been determined by Abel inversion. The radial temperature profiles are calculated from the emission coefficients including pressure measurements and the corresponding plasma composition. In contrast to previous studies, a specific iterative approach is proposed to consider the optical thickness of the plasma. A maximum optical thickness between 0.2 and 0.4 has been observed. Temperature profiles corrected for absorption effects show increasing maximum temperature in the arc axis with decreasing current towards current zero. The effect of the plasma composition on absolute arc temperatures is discussed. The temperature profiles can be used to validate CFD simulations of the switching-off process in the model chamber.

description: India imports more from Africa than Africa does from India. A large share of Indian imports from Africa are oil and minerals. However, the India-Africa relations in food and agriculture are already important but have potentials for expansion. For complex reasons Africa had no transformation of its agriculture comparable to India’s during its erstwhile Green Revolution in the 1960s and 70s. The African continent and the Indian Subcontinent still have a lot to learn from each other, especially as food systems and food value chains are modernizing and technologies in agriculture and food sectors are spreading. This paper looks at historical ties between India and Africa. It identifies trade and investment patterns in recent decades and describes the collaborations between India and several African countries in the field of agriculture. Finally, we point at potential areas for mutual cooperation in agriculture of the two regions in the future.

description: We analyze the macroscopic dynamics of a Bose gas in a harmonic trap with a superimposed two-dimensional optical lattice, assuming a weak coupling between different lattice sites. We consider the situation in which the local chemical potential at each lattice site can be considered as that provided by the Lieb-Liniger solution. Due to the weak coupling between sites and the form of the chemical potential, the three-dimensional ground-state density profile and the excitation spectrum acquire remarkable properties different from both 1D and 3D gases. We call this system a quasi-Tonks gas. We discuss the range of applicability of this regime, as well as realistic experimental situations where it can be observed.

description: Standing shocks are believed to be responsible for stationary Type II solar radio bursts, whereas drifting Type II bursts are excited by moving shocks often related to coronal mass ejections (CMEs). Observations of either stationary or drifting Type II bursts are common, but a transition between the two states has not yet been reported. Here, we present a Type II burst which shows a clear, continuous transition from a stationary to a drifting state, the first observation of its kind. Moreover, band splitting is observed in the stationary parts of the burst, as well as intriguing negative and positive frequency-drift fine structures within the stationary emissions. The relation of the radio emissions to an observed jet and a narrow CME was investigated across multiple wavelengths, and the mechanisms leading to the transitioning Type II burst were determined. We find that a jet eruption generates a streamer-puff CME and that the interplay between the CME-driven shock and the streamer is likely to be responsible for the observed radio emissions.

description: Les chiffres publiés le 24 septembre 2014 par la DARES semblent encourageants car ils présentent une baisse de 0.3% du taux de chômage des demandeurs d’emploi de catégorie A. Qu’en est il exactement ? Il ne s’agit en définitive que d’un changement d’un mois à un autre et si l’on observe les changements sur un trimestre, on doute que la tendance pourrait s’inverser. Au contraire, les développements substantiels des derniers mois et ce malgré les débats techniques concernant les chiffres de l’Insee de l’enquête emploi et ceux de Pôle emploi nous conduisent en définitive à une conclusion limpide. La situation de l’emploi en France a continué de se détériorer en 2014 et est des plus inquiétantes.
description:  The data released on September 24th, 2014 by the DARES is encouraging because it shows a decline of 0.3% in the Class A job seeker unemployment rate. But what does this really mean? Ultimately, the change is representative of slight fluctuation from one month to another. If we look at changes that have occurred during the last quarter, it is doubtful the longerterm trend could be reversed. In contrast, substantial developments in recent months, despite the technical discussions on figures from the INSEE employment survey and the Pôle Emploi, ultimately lead us to a clear conclusion. The employment situation in France has deteriorated further in 2014 and is of growing concern.

description: Dynamical emergent patterns of swarms are now fairly well established in nature, and include flocking and rotational states. Recently, there has been great interest in engineering and physics to create artificial self-propelled agents that communicate over a network and operate with simple rules, with the goal of creating emergent self-organizing swarm patterns. In this paper, we show that when communicating networks have range dependent delays, rotational states which are typically periodic, undergo a bifurcation and create swarm dynamics on a torus. The observed bifurcation yields additional frequencies into the dynamics, which may lead to quasi-periodic behavior of the swarm.

description: Granular materials demonstrate a strongly nonlinear behavior influencing the wave propagation in the medium. We report the first experimental observation of impulse energy confinement and the resultant disintegration of shock and solitary waves. The medium consists of alternating ensambles of high-modulus vs orders of magnitude lower modulus chains of different masses. The trapped energy is contained within the "softer" portions of the composite chain and is slowly released in the form of weak, separated pulses over an extended period of time. This effect is enhanced by using a specific group assembly and superimposed force.

In the preceding paper, we showed that the escape-time plot contains regular sequences of successive escape segments, called epistrophes, which converge geometrically upon each endpoint of every escape segment. In the present paper, we use topological techniques to: (1) show that there exists a minimal required set of escape segments within the escape-time plot; (2) develop an algorithm which computes this minimal set; (3) show that the minimal set eventually displays a recursive structure governed by an ``Epistrophe Start Rule'': a new epistrophe is spawned Delta = D+1 iterates after the segment to which it converges, where D is the minimum delay time of the complex.

THE VOLUME OF SOVIET MUNITIONS OUTPUT, 1937-1944: A REEVALUATION

description: The paper examines the official Soviet index of munitions output in World War II which was first published in 1965. This index seems to have been based on annual budgetary appropriations for expenditure on ground and air munitions at current prices; since Soviet munitions prices fell rapidly in war time, it grossly understates change in the real volume of war production. Subsequently published official data on the production of different lines of ground and air munitions in physical units, supplemented by information about real spending on naval munitions, supply a reliable foundation for a new index of the volume of total munitions output. New indices for different branches of the munitions industries can be calculated in Soviet prices of either 1941 or 1944, and combined using weights based on 1941 and 1944 expenditure shares. The result shows that Soviet munitions output underwent a fourfold expansion between 1940 and the 1944 peak. The new index can also be extended back to 1937, although with some loss of reliability. When this is done, Soviet munitions output at the 1944 peak is shown to have run at 10-11 times the 1937 rate. Lastly, the level and dynamic of Soviet munitions output measured in this way can be compared with the performance of similar measures of munitions output in World War II in other countries.

description: The conceptual difficulties associated with a cosmological constant have led to the investigation of alternative models in which the equation of state parameter, $w=p/ρ$, of the dark energy evolves with time. We show that combining the supernova type Ia observations {\it with the constraints from WMAP observations} restricts large variation of $ρ(z)$ at low redshifts. The combination of these two observational constraints is stronger than either one. The results are completely consistent with the cosmological constant as the source of dark energy.

description: We investigate the axion like particle (ALP)-photon oscillation effect in the high energy $γ$-ray spectra of PG 1553+113 and PKS 2155-304 measured by Fermi-LAT and H.E.S.S.. The choice of extragalactic background light (EBL) model, which induces the attenuate effect in observed $γ$-ray spectra, would affect the ALP implication. For the ordinary EBL model that prefers a null hypothesis, we set constraint on the ALP-photon coupling constant at 95% C.L. as $g_{aγ}\lesssim 5\times 10^{-11} ~\rm{GeV}^{-1}$ for the ALP mass $\sim 10$ neV. We also consider the CIBER observation of the cosmic infrared radiation, which shows an excess at the wave wavelength of $\sim 1~μ$m after the substraction of foregrounds. The high energy gamma-rays from extragalactic sources at high redshifts would suffer from a more significant attenuate effect caused by this excess. In this case, we find that the ALP-photon oscillation would improve the fit to the observed spectra of PKS 2155-304 and PG 1553+113 and find a favored parameter region at 95% C.L..

description: In this paper we investigate the asymptotic dynamics of inflationary cosmological models that are based in scalar-tensor theories of gravity. Our main aim is to explore the global structure of the phase space in the framework of single-field inflation models. For this purpose we make emphasis in the adequate choice of the variables of the phase space. Our results indicate that, although single-field inflation is generic in the sense that the corresponding critical point in the phase space exists for a wide class of potentials, along given phase space orbits -- representing potential cosmic histories -- the occurrence of the inflationary stage is rather dependent on the initial conditions. We have been able to give quantitative estimates of the relative probability (RP) for initial conditions leading to slow-roll inflation. For the non-minimal coupling model with the $ϕ^2$-potential our rough estimates yield to an almost vanishing relative probability: $10^{-13}\,\%\lesssim RP\ll 10^{-8}\,\%$. These bonds are greatly improved in the scalar-tensor models, including the Brans-Dicke theory, where the relative probability $1\,\%\lesssim RP\leq 100\,\%$. Hence slow-roll inflation is indeed a natural stage of the cosmic expansion in Brans-Dicke models of inflation. It is confirmed as well that the dynamics of vacuum Brans-Dicke theories with arbitrary potentials are non-chaotic.

description: We study the spectrum and eigenmodes of the QCD Dirac operator in a gauge background given by an Instanton Liquid Model (ILM) at temperatures around the chiral phase transition. For two massless quark flavors we observe that at the chiral phase transition, both the low lying eigenmodes and the spectrum of the QCD Dirac operator resemble those of a disordered conductor at the Anderson transition. In particular we present results showing that the eigenvectors are multifractal and the spectral correlations are well described by critical statistics. We also find an additional temperature dependent mobility edge located in the bulk of the spectrum with properties quantitatively similar to those of a 3D disordered conductor at the Anderson transition. This feature is present in both quenched and unquenched simulations. Finally we argue that our findings are not in principle restricted to the ILM approximation and may also be found in lattice simulations.

Effective containment explains sub-exponential growth in confirmed cases of recent COVID-19 outbreak in Mainland China

description: The recent outbreak of COVID-19 in Mainland China is characterized by a distinctive algebraic, sub-exponential increase of confirmed cases during the early phase of the epidemic, contrasting an initial exponential growth expected for an unconstrained outbreak with sufficiently large reproduction rate. Although case counts vary significantly between affected provinces in Mainland China, the scaling law $t^μ$ is surprisingly universal, with a range of exponents $μ=2.1\pm0.3$. The universality of this behavior indicates that despite social, regional, demographical, geographical, and socio-economical heterogeneities of affected Chinese provinces, this outbreak is dominated by fundamental mechanisms that are not captured by standard epidemiological models. We show that the observed scaling law is a direct consequence of containment policies that effectively deplete the susceptible population. To this end we introduce a parsimonious model that captures both, quarantine of symptomatic infected individuals as well as population wide isolation in response to mitigation policies or behavioral changes. For a wide range of parameters, the model reproduces the observed scaling law in confirmed cases and explains the observed exponents. Quantitative fits to empirical data permit the identification of peak times in the number of asymptomatic or oligo-symptomatic, unidentified infected individuals, as well as estimates of local variations in the basic reproduction number. The model implies that the observed scaling law in confirmed cases is a direct signature of effective contaiment strategies and/or systematic behavioral changes that affect a substantial fraction of the susceptible population. These insights may aid the implementation of containment strategies in potential export induced COVID-19 secondary outbreaks elsewhere or similar future outbreaks of other emergent infectious diseases.

description: We report on the vortex dimensionality of uranium-doped Ag/Bi2223 tapes, before and after irradiation to a thermal-neutron fluence. The effective activation energies as a function of current density and applied field were calculated from dynamic magnetisation relaxation measurements. A dimensional crossover from a 3D elastic creep regime to 2D plastic creep was observed in the nonirradiated tape at an applied magnetic field Hcr = 0.37 T, with an associated change in the flux hop velocity and temperature dependence of the activation energy. After introduction of the fission-fragment damage by irradiation, a shift in the crossover to Hcr = 0.65 T was observed. These results indicate an enhancement of the c-axis vortex coherence by the introduced splayed columnar defects, explaining the greater pinning efficiency of the uranium-fission method in Bi2223 rather than the less anisotropic Y123. Conflicting results obtained for the irradiated tape in the absence of any temperature scaling of the activation energies demonstrate the importance of the inclusion of scaling in the magnetisation relaxation analysis.

description: The triphenyltin(IV) complex of composition [Ph3Sn(3,5-(NO2)2C6H2(OH)CONHO)] (1) has been synthesized by the reaction of Ph3SnCl with potassium 3,5-dinitrosalicylhydroxamate [3,5-(NO2)2C6H2(OH)CONHOK] and characterized by physicochemical studies, spectroscopic techniques (IR, 1H 13C, and 119Sn NMR), and mass spectrometry. The electrochemical behavior of ligand and 1 have been studied by cyclic voltammetry. The thermal behavior of 1 has been studied by thermogravimetric techniques (TGA, DTG, and DTA) and various kinetic parameters have been calculated. The optimized geometry of 1 was computed by the DFT method using B3LYP/631-G* set. The vibrational frequencies, 1H and 13C NMR spectra have been computed and compared with the experimental data. The global descriptors have been calculated. The various thermodynamic parameters, Gibbs free energy (G), enthalpy (H), entropy (S), bond energy (E), constant heat volume capacity (Cv), internal energy (U), and dipole moment (µ) have been calculated. The in vitro antimicrobial activity assay against pathogenic gram-(−) bacteria viz. Salmonella typhi, Escherichia coli; gram-(+) bacteria Bacillus cereus and Staphylococcus aureus; and fungi Fusarium sambucinum and Rhizoctona solani by MIC method; the in vitro cytotoxicity on human muscle rhabdomyosarcoma (RD) by MTT method and the antioxidant potential by DPPH free radical scavenging showed higher inhibitory effect of 1 than ligand.

description: Soil moisture is critical component of crop health and monitoring it can enable further actions for increasing yield or preventing catastrophic die off. As climate change increases the likelihood of extreme weather events and reduces the predictability of weather, and non-optimal soil moistures for crops may become more likely. In this work, we a series of LSTM architectures to analyze measurements of soil moisture and vegetation indiced derived from satellite imagery. The system learns to predict the future values of these measurements. These spatially sparse values and indices are used as input features to an interpolation method that infer spatially dense moisture map for a future time point. This has the potential to provide advance warning for soil moistures that may be inhospitable to crops across an area with limited monitoring capacity.

description: Photonic crystals have provided a controllable platform to examine excitingly new topological states in open systems. In this work, we reveal photonic topological corner states in a photonic graphene with mirror-symmetrically patterned gain and loss. Such a nontrivial Wannier-type higher-order topological phase is achieved through solely tuning on-site gain/loss strengths, which leads to annihilation of the two valley Dirac cones at a time-reversal-symmetric point, as the gain and loss change the effective tunneling between adjacent sites. We find that the symmetry-protected photonic corner modes exhibit purely imaginary energies and the role of the Wannier center as the topological invariant is illustrated. For experimental considerations, we also examine the topological interface states near a domain wall. Our work introduces an interesting platform for non-Hermiticity-induced photonic higher-order topological insulators, which, with current experimental technologies, can be readily accessed.

description: The paper presents a previously unpublished index of the total British output of munitions, 1942-5. The index was produced in the Ministry of Production's Programmes Division under E.A.G. (now Professor Sir Austin) Robinson in both weekly and monthly versions. The Robinson index was used mainly for purposes of short run management of munitions production and manpower budgets. For today's more long run historical purposes the index can be revised and extended back to 1939 on a quarterly basis. The revised index shows a fourfold increase in British munitions output in the first 18 months of the war; by the 1944 peak, munitions output was running at more than six times the October-December 1939 rate. The level and dynamic of British munitions output estimated in this way can also be compared with the performance of similar indicators of munitions output in World War II in other countries.

description: Quantum gas microscopy has emerged as a powerful new way to probe quantum many-body systems at the microscopic level. However, layered or efficient spin-resolved readout methods have remained scarce as they impose strong demands on the specific atomic species and constrain the simulated lattice geometry and size. Here we present a novel high-fidelity bilayer readout, which can be used for full spin- and density-resolved quantum gas microscopy of two-dimensional systems with arbitrary geometry. Our technique makes use of an initial Stern-Gerlach splitting into adjacent layers of a highly-stable vertical superlattice and subsequent charge pumping to separate the layers by $21\,μ$m. This separation enables independent high-resolution images of each layer. We benchmark our method by spin- and density-resolving two-dimensional Fermi-Hubbard systems. Our technique furthermore enables the access to advanced entropy engineering schemes, spectroscopic methods or the realization of tunable bilayer systems.
Theory of spinor Fermi and Bose gases in tight atom waveguides

description: Divergence-free pseudopotentials for spatially even and odd-wave interactions in spinor Fermi gases in tight atom waveguides are derived. The Fermi-Bose mapping method is used to relate the effectively one-dimensional fermionic many-body problem to that of a spinor Bose gas. Depending on the relative magnitudes of the even and odd-wave interactions, the N-atom ground state may have total spin S=0, S=N/2, and possibly also intermediate values, the case S=N/2 applying near a p-wave Feshbach resonance, where the N-fermion ground state is space-antisymmetric and spin-symmetric. In this case the fermionic ground state maps to the spinless bosonic Lieb-Liniger gas. An external magnetic field with a longitudinal gradient causes a Stern-Gerlach spatial separation of the corresponding trapped Fermi gas with respect to various values of $S_z$.

description: This study investigates the potential for potable water savings by using rainwater in a home in Blumenau, southern Brazil. The water end-uses were estimated based on frequency and time of use of the water appliances. The water flow rates were measured using containers and a stopwatch. Besides the estimated water consumption, daily measurements were taken using a water meter. The water consumption estimated was compared with the consumption measured and the water end-uses were obtained. The water for activities that did not require potable water accounted for 46.5%. This percentage was used as input data in the Netuno computer programme along with other parameters for the design of a rainwater harvesting system. The use of rainwater in the house, using a 2,000-litre tank, would provide potable water savings equal to 44.8%. This study demonstrated that there is a great potential for the use of rainwater in single-family houses in Blumenau.

description: Abstract: This study investigates the role of church music in fostering community building and spiritual unity within multicultural congregations. A mixed-methods approach was employed, combining surveys, in-depth interviews, and participant observations in five diverse Christian churches. The research aimed to understand how musical practices contribute to social cohesion and shared spiritual experiences across different cultural groups. The results reveal three key factors that enhance unity in multicultural worship settings: (1) a diverse musical repertoire that reflects the cultural backgrounds of the congregation; (2) participatory music-making, where congregants actively engage in singing and playing instruments; and (3) culturally responsive worship planning, in which worship leaders intentionally incorporate music that resonates with the spiritual and cultural identities of their communities. These elements were found to bridge cultural divides, promoting a sense of belonging and collective worship. In addition, the study highlights the importance of inclusive musical leadership, where music ministers are sensitive to the cultural nuances of their congregations and foster an environment where all members feel represented. This approach not only strengthens the communal bonds within the church but also enhances the spiritual engagement of its members. The findings of this study offer valuable insights for church leaders, musicians, and worship planners seeking to cultivate unity in increasingly multicultural congregational contexts. By prioritizing diverse and participatory musical practices, churches can build more inclusive and spiritually unified communities.

The techniques developed in our experiment will be of significant importance for quantum information processing with linear optics.

Expected Detection and False Alarm Rates for Transiting Jovian Planets
Creators: name: Brown, Timothy M.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Ground-based searches for transiting Jupiter-sized planets have so far produced few detections of planets, but many of stellar systems with eclipse depths, durations, and orbital periods that resemble those expected from planets. I show that these detection rates are consistent with our present knowledge of binary and multiple-star systems, and of Jovian-mass extrasolar planets. Upcoming space-based searches for transiting Earth-sized planets will be largely unaffected by the sources of false alarms that afflict current ground-based searches, with one exception, namely distant eclipsing binaries whose light is strongly diluted by that of a foreground star. A byproduct of the rate estimation is evidence that the period distribution of extrasolar planets is depressed for periods between 5 and 200 days.

description: Whether those who claim benefits should face a work requirement has been an issue of long-standing social concern. Important examples of schemes which require work are the Californian workfare program, Indian food security schemes and the English Poor Law of 1834. We present two arguments for demanding work for benefits: first, a work requirement can scree the truly needy from those who are not in need of support and second, it can provide incentives for people to invest in skills which enable them to avoid poverty. In the context of a simple model of a target population with two ability types we find conditions under which a work requirement reduces the costs of poor relief, and those when it does not. We concentrate on a case when work done in return for benefits has no social value, showing that even if this is true, work requirements may be a valuable policy tool.

description: Laser-based angle-resolved photoemission spectroscopy (ARPES) and two-photon photoemission spectroscopy (2PPES) are employed to study the valence electronic structure of the Weyl semimetal candidate Td-WTe$_2$ along two high symmetry directions and for binding energies between $\approx$ -1 eV and 5 eV. The experimental data show a good agreement with band structure calculations. Polarization dependent measurements provide furthermore information on initial and intermediate state symmetry properties with respect to the mirror plane of the Td structure of WTe$_2$.
