description: Cesium telluride is an important photocathode as an electron source for particle accelerators. It has a relatively high quantum efficiency (>1%), is sufficiently robust in a photoinjector, and has a long lifetime. This photocathode is grown in-house for a new Argonne Wakefield Accelerator (AWA) beamline to produce high charge per bunch (~50 nC) in a long bunch train. Here, we present a study of the work function of cesium telluride photocathode using the Kelvin Probe technique. The study includes an investigation of the correlation between the quantum efficiency and the work function, the effect of photocathode aging, the effect of UV exposure on the work function, and the evolution of the work function during and after photocathode rejuvenation via heating.

description: Molecular oxygen was used to probe the mechanism of the phototransformation of chlorobenzene and 4-chloroanisole in organic solvents. Laser flash photolysis, electron paramagnetic resonance and product distribution studies clarified the reaction mechanisms of these compounds under a wide range of conditions. The main primary photochemical reaction step is the homolytic cleavage of the C-Cl bond to produce a triplet radical pair in the solvent cage. In non-polar solvents hydrogen abstraction, after radical diffusion, leads to reduction. In polar solvents, in addition to H-abstraction, electron transfer within the caged radical pair occurs and leads to an ion pair (phenyl cation and Cl-). In the presence of oxygen, phenyl radicals can form phenylperoxyl radicals which have a bathochromically shifted absorption, thus making the homolytic cleavage visible by flash photolysis. The peroxyl radicals can couple, leading to more polar compounds, or undergo back reaction to the phenyl radical. For concentrations of the aryl chlorides of higher than 10-3 M, dimerization becomes an important transformation process and occurs after reaction of the transients with ground state molecules. In addition, excimer formation is postulated to be involved in the dimerization process.
Search for new physics in events with opposite-sign leptons, jets, and missing transverse energy in pp collisions at sqrt(s) = 7 TeV

description: A search is presented for physics beyond the standard model (BSM) in final states with a pair of opposite-sign isolated leptons accompanied by jets and missing transverse energy. The search uses LHC data recorded at a center-of-mass energy sqrt(s) = 7 TeV with the CMS detector, corresponding to an integrated luminosity of approximately 5 inverse femtobarns. Two complementary search strategies are employed. The first probes models with a specific dilepton production mechanism that leads to a characteristic kinematic edge in the dilepton mass distribution. The second strategy probes models of dilepton production with heavy, colored objects that decay to final states including invisible particles, leading to very large hadronic activity and missing transverse energy. No evidence for an event yield in excess of the standard model expectations is found. Upper limits on the BSM contributions to the signal regions are deduced from the results, which are used to exclude a region of the parameter space of the constrained minimal supersymmetric extension of the standard model. Additional information related to detector efficiencies and response is provided to allow testing specific models of BSM physics not considered in this paper.

description: Two kinds of liquid crystalline monomers with different mesogenic units grafted graphene oxide (M2-g-GO and M4-g-GO) were successfully synthesised to enhance thermal and mechanical properties of nanocomposites, owing to the improvement of dispersion and interface interaction between the fillers (M2-g-GO and M4-g-GO) and the epoxy matrix (DGEBA, E-51). And the structures and comprehensive properties of M2-g-GO, M4-g-GO, and their nanocomposites were analysed using FTIR, SEM, XRD, Raman, DSC, TGA, and POM tests. Compared with the neat epoxy and 3 wt% GO/epoxy composites, thermal properties of M2-g-GO/epoxy and M4-g-GO/epoxy nanocomposites were obviously improved, meanwhile, mechanical property measures prove M2-g-GO/epoxy and M4-g-GO/epoxy nanocomposites that exhibit higher impact strength, flexural strength and modulus. For example, the Td5% of epoxy nanocomposites with 1, 2, 3, and 4 wt% M2-g-GO were around 385°C, which was about 15°C larger than that of the neat epoxy. The Td5% of epoxy nanocomposites with 2 and 3 wt% M4-g-GO were 383°C and 388°C, respectively, which was about 13°C and 18°C larger than that of the neat epoxy. In a word, the M2-g-GO and M4-g-GO as fillers exhibit underlying feasibility to improve thermal and mechanical properties of nanocomposites.

description: Application of a moderate external magnetic field increases the efficiency of triplet photoinitiators of polymerization. The reasons for this observation are briefly outlined. Such well-documented magnetic and spin effects as the magnetic isotope effect (MIE) and chemically induced dynamic nuclear and electron polarization (CIDNP and CIDEP) have been observed under the photolysis of photoinitiators. CIDEP results are emphasized. The study of CIDEP under the photolysis of initiators allows the detection and identification of free radicals of initiators and the spin multiplicity of the reacting photoinitiator (triplet or singlet). The transfer of the spin polarization of the initiator free radical to monomers is a promising technique for following radical reaction pathways. The results of a CIDEP study of the sensitized decomposition of phosphine oxide photoinitiators are presented.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Exact RG equations are discussed with emphasis on the role of the anomalous dimension $η$. For the Polchinski equation this may be introduced as a free parameter reflecting the freedom of such equations up to contributions which vanish in the functional integral. The exact value of $η$ is only determined by the requirement that there should exist a well defined non trivial limit at a IR fixed point. The determination of $η$ is related to the existence of an exact marginal operator, for which an explicit form is given. The results are extended to the exact Wetterich RG equation for the one particle irreducible action $Γ$ by a Legendre transformation. An alternative derivation of the derivative expansion is described. An application to $\N=2$ supersymmetric theories in three dimensions is described where if an IR fixed point exists then $η$ is not small.

description: Die deutsche Wirtschaft tritt weiter auf der Stelle. Nachdem es zu Jahresbeginn noch so aussah, als spränge der Konjunkturmotor endlich an, gab es im zweiten Quartal einen kleinen Rückschlag. Obwohl die Einkommen steigen und die Inflation mittlerweile nahe der Zielmarke von zwei Prozent liegt, halten die Menschen in Deutschland ihr Geld zusammen. Da die schwächelnde Industrie die Investitionen und Exporte straucheln ließ, ist der Aufschwung erst einmal verschoben – in diesem Jahr dürfte die Wirtschaftsleistung insgesamt stagnieren. Ab dem Jahresende wird es dann aber wohl aufwärts gehen, für die Jahre 2025 und 2026 ist ein Wachstum von 0,9 beziehungsweise 1,4 Prozent zu erwarten. Hauptstütze dürfte der private Konsum sein, der zwar langsamer als erwartet steigen wird, aber dennoch Impulse gibt. Solche entfalten im Zuge weltweit weiter sinkender Zinsen auch der Außenhandel und die Investitionen. Die Weltwirtschaft ist weiter auf Erholungskurs, hat sich im zweiten Quartal aber ebenfalls etwas schwächer als im ersten Quartal entwickelt. Insbesondere das Wachstum in China ist etwas ins Stocken geraten. Auch in den USA gibt es Anzeichen für eine bevorstehende konjunkturelle Abkühlung. Nach 3,8 Prozent in diesem Jahr dürfte die Weltwirtschaft 2025 nur noch um 3,5 Prozent wachsen und sich erst 2026 wieder etwas dynamischer entwickeln.

description: We report rigorous quantum calculations of the translation-rotation (T-R) eigenstates of the H_2 molecule in C60. The resulting level structure can be explained in terms of a few dominant features. These include the coupling between the orbital and the rotational angular momenta of H_2 to give the total angular momentum λ, and the splitting of the sevenfold degeneracy of T-R levels with λ = 3 by the nonsphericity of C60, according to the rules of the icosahedral I_h group.

description: We study the Poisson-Furstenberg boundary of random walks on permutational wreath products. We give a sufficient condition for a group to admit a symmetric measure of finite first moment with non-trivial boundary, and show that this criterion is useful to establish exponential word growth of groups. We construct groups of exponential growth such that all finitely supported (not necessarily symmetric, possibly degenerate) random walks on these groups have trivial boundary. This gives a negative answer to a question of Kaimanovich and Vershik.

Of Savagery and Civil Society: Pierre Clastres and the Transformation of French Political Thought
Creators: name: Moyn, Samuel
Publisher: name: Columbia University
Year: 2004
Subjects: History

description: This essay examines the thought of the French anthropologist Pierre Clastres (1938-1977). It situates his once-famous depiction of savage politics as a premonitory rejection of the state at the crossroads of several traditions, long- and short-term. First, Clastres's thought resonates with the primitivistic appeal by French "moralists" since the early modern period to the lifestyle of prehistoric societies; second, it casts light on the history of French anthropology in the crisis years of structuralism; and third, it reflects the revival of Friedrich Nietzsche in French thought of the era. Above all, however, the essay explains Clastres's thought as an attempt to resist and to overcome the well-known communist allegiances of postwar French intellectuals. Early in rejecting communism, Clastres owed his prominence to the 1970s popularization of the critique of "totalitarianism." The so-called "passing of an illusion" of communism, one version of which Clastres pioneered, is often interpreted as the replacement of confusion with truth. It is more interesting, the essay suggests, to situate it in its time, as a complex achievement as defective as it was creative, if Clastres's thought is taken as an example. In closing, the essay suggests some legacies, often unintentional, Clastres left behind in French political thought of the years since his death.

description: We study the electromagnetic Dalitz decay modes of $J/ψ\rightarrow P l^+l^-$ ($P= π^0$, $η$ or $η^\prime$). In these decays, the lepton pairs are formed by internal conversion of an intermediate virtual photon with invariant mass $m_{l^+l^-}$. Study of the effective-mass spectrum of the $l^+l^-$ will shed light on the dynamic transition form factor $F_{J/ψP}(q^2)$ ($q^2 = m^2_{l^+l^-}$), which characterizes the electromagnetic structure arising at the vertex of the transition $J/ψ$ to pseudoscalars. We also discuss the direct productions of a GeV scale vector $U$ boson in these processes $J/ψ\rightarrow PU$ ($U\rightarrow l^+l^-$). It is responsible for mediating a new $U(1)_d$ interaction, as recently exploited in the context of weakly interacting massive particle dark matter. In this paper, we firstly use the usual pole approximation for the form factor to estimate the decay rate of $J/ψ\rightarrow P l^+l^-$ in the standard model. Then the reach of searching for the dark photon is estimated. We suggest that these Dalitz decays can be used to search for the light $U$ boson in the BESIII experiment with a huge $J/ψ$ data set.

description: We demonstrate that ultrafast nonlinear dynamics gives rise to reciprocity breaking in a random photonic medium. Reciprocity breaking is observed via the suppression of coherent backscattering, a manifestation of weak localization of light. The effect is observed in a pump-probe configuration where the pump induces an ultrafast step-change of the refractive index during the dwell time of the probe light in the material. The dynamical suppression of coherent backscattering is reproduced well by a multiple scattering Monte Carlo simulation. Ultrafast reciprocity breaking provides a distinct mechanism in nonlinear optical media which opens up avenues for the active manipulation of mesoscopic transport, random lasers, and photon localization.

description: It is not, of course, a new suggestion to turn history on itself in order to discover the historical conditions for the possibility of the modern historical outlook. This project began in the early modern period, taking on a new direction and momentum with J. C. Gatterer's complaint that his discipline had studiously exempted itself from the methods it pioneered. Few recent contributors to this ongoing endeavor, perhaps, have undertaken as interesting or fundamental a version of it as the late Amos Funkenstein. As his student Abraham P. Socher has recently observed, "One of Amos Funkenstein's central historical concerns was the development of the discipline and methods of history itself." Nonetheless, Funkenstein's contribution in this realm of inquiry remains little-known and ill-understood; this paper attempts a critical overview of it.
Brane Effective Actions, Kappa-Symmetry and Applications

Year: 2011
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: This is a review on brane effective actions, their symmetries and some of its applications. Its first part uncovers the Green-Schwarz formulation of single M- and D-brane effective actions focusing on kinematical aspects : the identification of their degrees of freedom, the importance of world volume diffeomorphisms and kappa symmetry, to achieve manifest spacetime covariance and supersymmetry, and the explicit construction of such actions in arbitrary on-shell supergravity backgrounds. Its second part deals with applications. First, the use of kappa symmetry to determine supersymmetric world volume solitons. This includes their explicit construction in flat and curved backgrounds, their interpretation as BPS states carrying (topological) charges in the supersymmetry algebra and the connection between supersymmetry and hamiltonian BPS bounds. When available, I emphasise the use of these solitons as constituents in microscopic models of black holes. Second, the use of probe approximations to infer about non-trivial dynamics of strongly coupled gauge theories using the AdS/CFT correspondence. This includes expectation values of Wilson loop operators, spectrum information and the general use of D-brane probes to approximate the dynamics of systems with small number of degrees of freedom interacting with larger systems allowing a dual gravitational description. Its final part briefly discusses effective actions for N D-branes and M2-branes. This includes both SYM theories, their higher order corrections and partial results in covariantising these couplings to curved backgrounds, and the more recent supersymmetric Chern-Simons matter theories describing M2-branes using field theory, brane constructions and 3-algebra considerations.

description: The reactions of carbon centered radical pairs often involve diffusion controlled combination and/or disproportionation reactions which are non-selective. A triplet geminate pair of radicals is produced by the photolysis of suitable ketones. The reactions of such geminate pairs can be controlled though the application of supramolecular concepts which emphasize non-covalent interaction to  steer  the geminate pair toward a selected pathway. In addition, "superdupermolecular" concepts, which emphasize the control of radical pair reactions through the orientation of electron spins, can be employed to further control the course of geminate pair reactions. Examples of control of a range of the selectivity of geminate radical combinations, which form strong covalent bonds, through supramolecular and superdupermolecular effects will be presented for the photolysis of ketones adsorbed in the supercages of zeolites.

description: We analyze the possibilities of detection of hypothetical exoplanets in coorbital motion from synthetic radial velocity (RV) signals, taking into account different types of stable planar configurations, orbital eccentricities and mass ratios. For each nominal solution corresponding to small-amplitude oscillations around the periodic solution, we generate a series of synthetic RV curves mimicking the stellar motion around the barycenter of the system. We then fit the data sets obtained assuming three possible different orbital architectures: (a) two planets in coorbital motion, (b) two planets in a 2/1 mean-motion resonance, and (c) a single planet. We compare the resulting residuals and the estimated orbital parameters. For synthetic data sets covering only a few orbital periods, we find that the discrete radial velocity signal generated by a coorbital configuration could be easily confused with other configurations/systems, and in many cases the best orbital fit corresponds to either a single planet or two bodies in a 2/1 resonance. However, most of the incorrect identifications are associated to dynamically unstable solutions. We also compare the orbital parameters obtained with two different fitting strategies: a simultaneous fit of two planets and a nested multi-Keplerian model. We find that the nested models can yield incorrect orbital configurations (sometimes close to fictitious mean-motion resonances) that are nevertheless dynamically stable and with orbital eccentricities lower than the correct nominal solutions. Finally, we discuss plausible mechanisms for the formation of coorbital configurations, by the interaction between two giant planets and an inner cavity in the gas disk. For equal mass planets, both Lagrangian and anti-Lagrangian configurations can be obtained from same initial condition depending on final time of integration.

description: A high-precision ohmmeter that delivers rectangular pulses to the connected thermal sensors of various designs was developed. During the heating pulse, the electrical resistance of the sensor(s) is measured at a given frequency. The thermophysical properties of the objects under study are calculated according to conventional models. The device is capable of implementing both absolute and relative measurements, which are carried out in one pulse. The uncertainty of the measured current-voltage characteristics of the measurement channel was estimated. Experiments were conducted on human skin using small-size Pt100 platinum resistance thermometers on a substrate. The use of modern sensors on a coated substrate extends the application range of the developed device in terms of non-destructive analysis of such thermophysical properties, as thermal conductivity, thermal activity, thermal diffusivity, boiling and melting temperatures of conductive and magnetically conductive measurement objects. The compact size of the sensor permits investigations on small volumes. The range of measured temperatures and pressures is determined by the sensor. The device compactness enables its use for both industrial purposes in laminar flow environments and educational purposes. The device can be used to study the thermophysical properties of plastic amorphous and bulk materials, biological and plant objects, liquids and gases and their mixtures, solids, inhomogeneous bodies in structure with and without a melting component. The irregular thermal regime allows fast and/or irreversible processes with a thermal field to be studied.Rezhime-1 Ohmmeter for Investigating Thermophysical Properties of Substances and Materials at Rest and in Flux // LETI Transactions on Electrical Engineering & Computer Science. 2023.

description: A high-precision ohmmeter that delivers rectangular pulses to the connected thermal sensors of various designs was developed. During the heating pulse, the electrical resistance of the sensor(s) is measured at a given frequency. The thermophysical properties of the objects under study are calculated according to conventional models. The device is capable of implementing both absolute and relative measurements, which are carried out in one pulse. The uncertainty of the measured current-voltage characteristics of the measurement channel was estimated. Experiments were conducted on human skin using small-size Pt100 platinum resistance thermometers on a substrate. The use of modern sensors on a coated substrate extends the application range of the developed device in terms of non-destructive analysis of such thermophysical properties, as thermal conductivity, thermal activity, thermal diffusivity, boiling and melting temperatures of conductive and magnetically conductive measurement objects. The compact size of the sensor permits investigations on small volumes. The range of measured temperatures and pressures is determined by the sensor. The device compactness enables its use for both industrial purposes in laminar flow environments and educational purposes. The device can be used to study the thermophysical properties of plastic amorphous and bulk materials, biological and plant objects, liquids and gases and their mixtures, solids, inhomogeneous bodies in structure with and without a melting component. The irregular thermal regime allows fast and/or irreversible processes with a thermal field to be studied.Rezhime-1 Ohmmeter for Investigating Thermophysical Properties of Substances and Materials at Rest and in Flux // LETI Transactions on Electrical Engineering & Computer Science. 2023.

description: Climate-induced migration is a global challenge. Climate change intensifies the frequency and severity of disasters, thereby increasing the number of people displaced by extreme weather events. Adverse climate change impacts are already exacerbating patterns of human mobility, and will do so in greater magnitude in the future. Yet no comprehensive framework governs climate-induced migration, and international law guarantees no protection to climate migrants who fall outside the definition of international refugee law. Given this protection gap, policy solutions that address climate-induced migration are critical. This paper proposes Free Movement Agreements (FMAs) as a protection framework for climate-induced migration in the absence of a governing legal framework and guaranteed legal rights. FMAs are provisions within (sub-)regional trade agreements that liberalize the movement of people between participating states. Two Caribbean FMAs within the Caribbean Community (CARICOM) and Organisation for Eastern Caribbean States (OECS) provided people displaced during the 2017 Atlantic Hurricane Season rights of entry, work, and resettlement. Given that 120 countries worldwide participate in FMAs, FMAs could be useful in other regional contexts. FMAs are particularly well-suited to address the climate-induced migration protection gap because they grant access to territory and safety regardless of the drivers of movement, which are often difficult to disaggregate. FMAs also provide a regional response to a regional challenge, build economic resilience at the structural and individual level, and are more easily amended than global multilateral agreements.

description: Die einfache Bedienung und die vielseitigen Anwendungsmöglichkeiten generativer Künstlicher Intelligenz (KI) bergen das Potenzial, verschiedene Aufgaben zu automatisieren und somit die Arbeitswelt grundlegend zu verändern. Vor allem freiberufliche Tätigkeiten im Digitalbereich, die durch kurzfristige und flexible Arbeitsaufträge gekennzeichnet sind, sehen sich bereits einer wachsenden Konkurrenz durch generative KI-Technologien (wie beispielsweise ChatGPT) ausgesetzt. Eine Analyse der Nachfrage nach Freelance-Arbeit auf Online-Plattformen deutet auf einen signifikanten Rückgang in der Anzahl von Aufträgen für Tätigkeiten hin, die leicht automatisiert werden können. Dies betrifft unter anderem die Bereiche Schreibarbeit, Software-, App- und Web-Entwicklung sowie Grafikdesign. Verbleibende Aufträge sind zudem komplexer und haben auch ein höheres Budget. Gezielte Weiterbildungs- und Umschulungsprogramme zum Umgang und Arbeiten mit generativer KI sind notwendig, um Beschäftigte auf den Einsatz generativer KI vorzubereiten und negative Auswirkungen auf die Nachfrage nach Freelance-Arbeit abzufedern.

description: The search for successful generation 3 immersion lithography fluids is focused on high refractive index fluids which are transparent to 193 nm light. This search has led to saturated hydrocarbons which have been shown potential in this field. This paper discusses our observations that many immersion fluid candidates (saturated hydrocarbons and acetonitrile) were observed to polymerize upon irradiation with 193 nm light.
Design of an optical uroflowmeter and assessing bladder pressure through video analysis of the male urine stream
Creators: name: Wiens, Kristy
Publisher: name: University of British Columbia

description: Voiding dysfunction, such as benign prostatic hyperplasia and impaired detrusor contractility, affects more than half of men over the age of 50. Uroflowmetry provides quantitative information of flow dysfunction by measuring the flow rate and total volume of urine expelled by the body. The majority of existing clinical uroflowmeters determine flow rate using a scale to measure increasing mass of urine expelled with time; however, they are expensive and typically found only in specialists’ offices, making it difficult for patients to receive testing. An opportunity therefore exists to develop a much more affordable device which would allow flow rate testing to become a part of routine care and to be conducted in a wider variety of environments such as General Practitioners’ offices and home monitoring. The high demand for digital cameras, particularly due to their extensive use in mobile devices, has resulted in their accelerated advancement and cost reduction. Therefore, a device based on this technology is investigated. In addition to the development of this device, a study was conducted to investigate if information regarding bladder pressure may be obtained by analyzing digital images of the urine stream. Voiding dysfunction may result in abnormally high bladder pressure, caused by urinary obstruction, or low bladder pressure which may be caused by reduced detrusor contractility. The clinical implications and treatment for these two cases are very different; however, they present with similar low flow rate voiding patterns and cannot currently be distinguished non-invasively. It was postulated that increased inertia and turbulence may exist in high pressure flows, and may be identifiable in the digital images of the urine stream.
