description: We present the results of optical spectroscopic observations of CI Cam. Double-peaked profiles were simultaneously observed for the first time in the hydrogen Balmer, He {\small I} $λ$6678 and Fe {\small II} lines during an observational run in 2001 September. An intermediate viewing angle of the circumstellar disk around the B[e] star is consistent with our data. A significant decrease in the intensity of the H$α$ and He {\small I} lines in our 2004 September observations might have been the precursor of a line outburst at the end of 2004. The remarkable increase in the intensity of all lines and the decrease in visual brightness in 2005 might be due to the environment filling with new material ejected during the outburst. The environment of CI Cam is influenced by mass loss from the B[e] star and the outburst of its compact companion.

description: In atmospheric pressure capacitively coupled microplasma jets, Voltage Waveform Tailoring (VWT) was demonstrated to provide ultimate control of the Electron Energy Distribution Function (EEDF), which allows to enhance and adjust the generation of selected neutral species by controlling the electron power absorption dynamics. However, at the fundamental level, the physical origin of these effects of VWT remained unclear. Therefore, in this work, the electron power absorption dynamics is investigated in a He/N$_2$ jet with a nitrogen concentration of 0.05\% driven by a valleys waveform at a base frequency of 13.56 MHz for different numbers of harmonics using a self-consistent Particle in Cell simulation coupled with a spatio-temporally resolved analysis of the electron power absorption based on the momentum balance equation. Due to the local nature of the transport at atmospheric pressure, ohmic power absorption is dominant. Increasing the number of harmonics, due to the peculiar shape of the excitation waveform the sheath collapse at the grounded electrode is shortened relative to the one at the powered electrode. As a consequence, and in order to ensure flux compensation of electrons and positive ions at this electrode, a high current is driven through the discharge at the time of this short sheath collapse. This current is driven by a high ohmic electric field. Close to the grounded electrode, where the electron density is low and the electric field is high, electrons are accelerated to high energies and strong ionization as well as the formation of a local electron density maximum are observed. This electron density maximum leads to a local ambipolar electric field that acts as an electric field reversal and accelerates electrons to even higher energies. These effects are understood in detail to fundamentally explain the unique potential of VWT for EEDF control in such plasmas.

description: We present spectroscopic and photometric results of Nova V1280 Sco which was discovered in outburst in early 2007 February. The large number of spectra obtained of the object leads to one of the most extensive, near-infrared spectral studies of a classical nova. The spectra evolve from a P-Cygni phase to an emission-line phase and at a later stage is dominated by emission from the dust that formed in this nova. A detailed model is computed to identify and study characteristics of the spectral lines. Inferences from the model address the vexing question of which novae have the ability to form dust. It is demonstrated, and strikingly corroborated with observations, that the presence of lines in the early spectra of low-ionization species like Na and Mg - indicative of low temperature conditions - appear to be reliable indicators that dust will form in the ejecta. It is theoretically expected that mass loss during a nova outburst is a sustained process. Spectroscopic evidence for such a sustained mass loss, obtained by tracing the evolution of a P-Cygni feature in the Brackett gamma line, is presented here allowing a lower limit of 25-27 days to be set for the mass-loss duration. Photometric data recording the nova's extended 12 day climb to peak brightness after discovery is used to establish an early fireball expansion and also show that the ejection began well before maximum brightness. The JHK light curves indicate the nova had a fairly strong second outburst around 100 days after the first.

description: Symmetric Teleparallel Gravity is an exceptional theory of gravity that is consistent with the vanishing affine connection. This theory is an alternative and a simpler geometrical formulation of general relativity, where the non-metricity $Q$ drives the gravitational interaction. Our interest lies in exploring the cosmological bouncing scenarios in a flat Friedmann-Limaître-Robertson-Walker (FLRW) spacetime within this framework. We explore bouncing scenarios with two different Lagrangian forms of $f(Q)$ such as a linearly and non-linearly dependence on $Q$. We have successfully examined all the energy conditions and stability analysis for both models to present a matter bounce.

Pressure-driven instabilities in astrophysical jets
Creators: name: Longaretti, Pierre-Yves
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Astrophysical jets are widely believed to be self-collimated by the hoop-stress due to the azimuthal component of their magnetic field. However this implies that the magnetic field is largely dominated by its azimuthal component in the outer jet region. In the fusion context, it is well-known that such configurations are highly unstable in static columns, leading to plasma disruption. It has long been pointed out that a similar outcome may follow for MHD jets, and the reasons preventing disruption are still not elucidated, although some progress has been accomplished in the recent years. In these notes, I review the present status of this open problem for pressure-driven instabilities, one of the two major sources of ideal MHD instability in static columns (the other one being current-driven instabilities). I first discuss in a heuristic way the origin of these instabilities. Magnetic resonances and magnetic shear are introduced, and their role in pressure-driven instabilities discussed in relation to Suydam's criterion. A dispersion relation is derived for pressure-driven modes in the limit of large azimuthal magnetic fields, which gives back the two criteria derived by Kadomtsev for this instability. The growth rates of these instabilities are expected to be short in comparison with the jet propagation time. What is known about the potential stabilizing role of the axial velocity of jets is then reviewed. In particular, a nonlinear stabilization mechanism recently identified in the fusion literature is discussed. Key words: Ideal MHD: stability, pressure-driven modes; Jets: stability

description: This paper deals with the impact of direct bupati (district head) elections on local politics with regard to land confl icts in the district of Paser, Indonesia. I discuss the position and infl uence of non-governmental organizations (NGOs) in this process and their usage of adat-based land claims. The paper is concerned with the internal political context of government-NGO power relations as well as with the position and profi ling of these parties in Paserese society at large. The subject is approached through a discussion of two ‘land’ occupations (one in fact being a sea occupation) by groups claiming adat rights, and of the measures taken by the local government and NGOs alike. The new importance of regional politics and local responsibility of those in power in Paser are reviewed against the background of Indonesian political reform. I argue that results are likely to be determined by a specifi c local context and momentum rather than by nationwide developments.

description: The clove cigarettes (kretek) industry is the second largest employer in Indonesia, after the Indonesian government. Between 4 and 17 million people are employed in this industry, including areas such as cultivation, trading, transport, advertisement and production of clove cigarettes. The Indonesian government depends on the kretek industry because of its important economic function. This paper contributes to tracing the historical development of kretek, considering economic, social and political aspects. The article raises the question which factors have determined the consumption behaviour of smoking? Why has betel chewing increasingly been replaced by smoking kretek cigarettes? Which steps has the kretek cigarette taken since its invention and what factors have mechanization, political intervention, tobacco control and advertisement played for the development of the kretek industry? What image do kretek cigarettes have today, what are its patterns of consumption and what infl uence do multinational enterprises have on the development of kretek?

description: The existence of a gradient in the Faraday rotation measure (RM) of the quasar 3C 273 jet is confirmed by follow-up observations. A gradient transverse to the jet axis is seen for more than 20 mas in projected distance. Taking account of the viewing angle, we estimate it to be more than 100 pc. Comparing to the distribution of the RM in 1995, we detect a time variation of it at the same distance from the core over 7 yr. We discuss the origin of the Faraday rotation based on this rapid time variation. We rule out foreground media such as a narrow-line region, and suggest a helical magnetic field in the sheath region as the origin of this gradient of the RM.

description: We present the experimental InfraRed Multiple Photon Dissociation (IRMPD) spectrum and fragmentation mass spectrum of the irregular, cationic PAH dibenzo[a,l]pyrene (C$_{24}$H$_{14}^+$) in the 6-40 $μ$m / 250-1650 cm$^{-1}$ range. The use of the the Free-Electron Laser for IntraCavity Experiments (FELICE) enabled us to record its Far-InfraRed (FIR) spectrum for the first time. We aim to understand how irregularity affects the infrared spectrum and fragmentation chemistry of PAHs. Dibenzo[a,l]pyrene is an asymmetric, non-planar molecule, for which all vibrational modes are in principle IR-active. Calculated harmonic Density Function Theory (DFT) and anharmonic Density Functional based Tight Binding Molecular Dynamics (DFTB-MD) spectra show a large wealth of bands, which match the experiment well, but with a few differences. The periphery of the molecule contains several edge geometries, but out of all possible modes in the 11-14 $μ$m out-of-plane C-H bending region, only one band at 13.5 $μ$m is prominent. This fact and the richness of the C-C stretching range make irregular PAHs a possible contributor to D-class interstellar spectra. The fragmentation mass spectra reveal facile 2H-loss and no [2C, 2H]-loss, which is attributed to the sterically hindered, non-planar cove region, which could protect irregular PAHs from radiation damage.

description: We present a formal connection between Lagrangian and Eulerian velocity increment distributions which is applicable to a wide range of turbulent systems ranging from turbulence in incompressible fluids to magnetohydrodynamic turbulence. For the case of the inverse cascade regime of two-dimensional turbulence we numerically estimate the transition probabilities involved in this connection. In this context we are able to directly identify the processes leading to strongly non-Gaussian statistics for the Lagrangian velocity increments.

description: The hypertriton bound state is relevant for inference of knowledge about the hyperon-nucleon (YN) interaction. In this work we compute the binding energy of the hypertriton using the ab initio hypernuclear no-core shell model (NCSM) with realistic interactions derived from chiral effective field theory. In particular, we employ a large family of nucleon-nucleon interactions with the aim to quantify the theoretical precision of predicted hypernuclear observables arising from nuclear-physics uncertainties. The three-body calculations are performed in a relative Jacobi-coordinate harmonic oscillator basis and we implement infrared correction formulas to extrapolate the NCSM results to infinite model space. We find that the spread of the predicted hypertriton binding energy, attributed to the nuclear-interaction model uncertainty, is about 100 keV. In conclusion, the sensitivity of the hypertriton binding energy to nuclear-physics uncertainties is of the same order of magnitude as experimental uncertainties such that this bound-state observable can be used in the calibration procedure to constrain the YN interactions.

Rainfall estimation from satellite images
Creators: name: Ingraham, Diane Verna
Publisher: name: University of British Columbia
Year: 2010

description: The design, management and operation (as well as the associated costs) of major water resource projects are directly related to the assessment of the anticipated volumes of runoff to be handled by the project. In remote or sparsely gauged regions it is often very difficult to determine these volumes due to a lack of data. The meteorological satellites, and in particular, the Geostationary Operational Environmental Satellites (GOES) can provide good areal coverage of the Earth and its weather systems potentially every half hour day and night. Since the first meteorological satellite images were transmitted, many attempts have been made to estimate rainfall using the images to identify specific cloud characteristics and correlating these with expected rainfall. However, these methods have been limited to convective rainfall in the tropics or near tropics. A method is presented here for estimating half-hourly rainfall which relates the vertical updraft velocities and hence, the moisture flux into the cloud, to the rate of vertical and horizontal growth of the cloud top as revealed in the GOES infrared images. The method performs well in estimating rainfall from widespread frontal systems common over British Columbia. A number of computational difficulties which arose during the research were resolved. One was to ascertain cloud top temperature contours for those GOES infrared images which were not enhanced. This involved the use of a video camera-special effects generator-video monitor system. The second was one of bookkeeping to "keep track of" the individual cloud cells. This was taken care of through the use of computer routines which directed the input and output of data, accounted for the growth and movement of the storm cells over the region and interpolated for rainfall at those locations which fell between adjacent precipitation contours. The method was used to estimate rainfall for a number of test storms occurring over British Columbia. The results were remarkably successful although there were some local inadequacies. An updating -procedure was developed in which the satellite estimated values of rainfall were improved by taking into consideration the information provided by concurrent rainfall observations. Furthermore, the parameters of the updating model (determined for gauged -locations) can be used to update rainfall estimates for ungauged locations. In the light of present raingauge installation and operating costs and the limitations of radar in mountainous areas, the satellite rainfall estimation procedure provides an economical operational supplement to existing conventional precipitation data collection.

description: This paper discusses the recent palm oil expansion as a multiple crisis of climate change, biodiversity loss, and (failed) development. It draws on recent research on the Malaysian “Palm Oil Industrial Complex” and on transnational campaign coalitions around palm oil to explore the transnational dimensions of the palm oil crisis. It argues that a new campaign coalition around the issue of agrofuel policies in the European Union has emerged that links social and environmental struggles in Indonesia and Europe. This new transnational activism not only rejects the palm oil development paradigm, but also points to possible alternative development futures.

description: Background: The COVID-19 pandemic has highlighted the need for robust diagnostic tools capable of detecting the disease from diverse and evolving data sources. Machine learning models, especially convolutional neural networks (CNNs), have shown promise. However, the dynamic nature of real-world data can lead to model drift, where performance degrades over time as the underlying data distribution changes. Addressing this challenge is crucial to maintaining accuracy and reliability in diagnostic applications.
 Objective: This study aims to develop a framework that monitors model drift and employs adaptation mechanisms to mitigate performance fluctuations in COVID-19 detection models trained on dynamic audio data.
 Methods: Two crowd-sourced COVID-19 audio datasets, COVID-19 Sounds and COSWARA, were used. Each was divided into development and post-development periods. A baseline CNN model was trained and evaluated using cough recordings from the development period. Maximum mean discrepancy (MMD) was used to detect changes in data distributions and model performance between periods. Upon detecting drift, retraining was triggered to update the baseline model. Two adaptation approaches were compared: unsupervised domain adaptation (UDA) and active learning (AL).
 Results: UDA improved balanced accuracy by up to 22% and 24% for the COVID-19 Sounds and COSWARA datasets, respectively. AL yielded even greater improvements, with increases of up to 30% and 60%, respectively.
 Conclusions: The proposed framework addresses model drift in COVID-19 detection, enabling continuous adaptation to evolving data. This approach ensures sustained model performance, contributing to robust diagnostic tools for COVID-19 and potentially other infectious diseases.

description: We present the results of the spectroscopic observations of HDE 226868, the optical counterpart to the black hole X-ray binary Cyg X-1, from 2001 to 2006. We analyze the variabilities of the two components in the complex H$α$ line: one P-Cygni shaped component which follows the motion of the supergiant and another emission component moving with an antiphase orbital motion relative to the supergiant, which is attributed to a focused-stellar wind. The results of KOREL disentangling of our spectra indicate that the focused stellar wind is responsible for the major part of the variability of the H$α$ emission line. The emission of the supergiant component had a small difference between the low/hard and high/soft states, while the focused wind component became strong in the low/hard state and weak in the high/soft state. The wind is nearly undisturbed by the X-ray photoionization during the low/hard state. However, during the high/soft state, the X-rays from the compact object could decelerate the line-driven wind and result in a high mass accretion rate, due to the effect of the X-ray photoionization. The X-ray illuminating could also change the temperature profile of the stellar wind and increase its temperature, and thus decrease the H$α$ emissivity of the wind, which could explain the H$α$ variabilities of Cyg X-1 during different X-ray states.

Continuity in a Changing World: Malaysia’s Coercive Security Apparatus in the Age of Terror and Beyond
Creators: name: Humphreys, Andrew
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2009

description: The Malaysian government’s use of its repressive security legislation has had a signifi cant impact on Malaysia’s modern political history. The focus of the present article is on the government’s use of its coercive security apparatus since the terrorist attacks of 9/11. My argument is that the apparatus is largely unchanged by the current global climate of the ‘War on Terror.’ Notably, Malaysia’s use of coercion has become increasingly less criticized by other governments, notably those in the West. Perhaps as a consequence, the government has become increasingly bold in its crackdowns against opposition elements. Following the political upheaval of the 2008 election, however, the future of the security apparatus is in question.

description: In present article we consider an axion F(R) gravity model and described with the help of holographic principle the cosmological models of viscous dark fluid coupled with axion matter in a spatially flat Friedmann-Robertson-Walker (FRW) universe. This description based on generalized infrared-cutoff holographic dark energy, proposed by Nojiri and Odintsov. We explored the Little Rip, the Pseudo Rip, and the power-law bounce cosmological models in terms of the parameters of the inhomogeneous equation of the state of viscous dark fluid and calculated the infrared cutoffs analytically. We represented the energy conservation equation for the dark fluid from a holographic point of view and showed a correspondence between the cosmology of a viscous fluid and holographic cosmology. We analyzed the autonomous dynamic system. In the absence of interaction between fluids, solutions are obtained corresponding to two cases. In the first case, dark energy is missing and the extension describes the component of dark matter. The second case corresponds to cosmological models with an extension due to dark energy. The solutions obtained are investigated for stability. For a cosmological model with the interaction of a special type, the stability of solutions of the dynamic system is also investigated.

description: We present results from multifrequency polarimetry of NRAO 140 using the Very Long Baseline Array. These observations allow us to reveal the distributions of both the polarization position angle and the Faraday rotation measure (RM). These distributions are powerful tools to discern the projected and line-of-sight components of the magnetic field, respectively. We find a systematic gradient in the RM distribution, with its sign being opposite at either side of the jet with respect to the jet axis. The sign of the RM changes only with the direction of the magnetic field component along the line of sight, so this can be explained by the existence of helical magnetic components associated with the jet itself. We derive two constraints for the pitch angle of the helical magnetic field from the distributions of the RM and the projected magnetic field; the RM distribution indicates that the helical fields are tightly wound, while that of the projected magnetic field suggests they are loosely wound around the jet axis. This inconsistency may be explained if the Faraday rotator is not cospatial with theemitting region. Our results may point toward a physical picture in which an ultra-relativistic jet (spine) with a loosely wound helical magnetic field is surrounded by a sub-relativistic wind layer (sheath) with a tightly wound helical magnetic field.

Santi Asoke Buddhism and the Occupation of Bangkok International Airport

description: Thailand experienced dramatic political turmoil from February 2006 to November 2008 culminating in the occupation of the Bangkok International Airport. The demonstrations against then Prime Minister Thaksin Shinawatra and his political allies were organised by the People’s Alliance for Democracy (PAD). One of the PAD leaders, Major-General Chamlong Srimuang, is an active member of the Buddhist Santi Asoke group. The group is controversial as it is not under the state Buddhist authorities and has implicitly criticised the Thai state Buddhist monks for moral corruption. Known as the ‘Dharma Army’, hundreds of Santi Asoke monks, nuns and lay people participated in PAD demonstrations. This paper analyses what the Santi Asoke Buddhist group represents, what the ‘Dharma Army’ is, how its reality differs from media images, what the ideological reasons for Asoke to initially support Thaksin were, and why the group finally turned against him. The paper argues that the group cannot be viewed as a monolithic community. Instead, it should be considered as an amalgamation of monks and nuns, urban and rural temple residents, lay followers of Asoke monks, practitioners of organic agriculture in Asoke village communities, students and former students of Asoke schools, and supporters of Major-General Chamlong Srimuang. Representatives of all these networks participated in the demonstrations albeit with different intensity.

description: Hot accretion flows contain collisionless plasmas that are believed to be capable of accelerating particles to very high energies, as a result of turbulence generated by the magnetorotational instability (MRI). We conduct unstratified shearing-box simulations of the MRI turbulence in ideal magnetohydrodynamic (MHD), and inject energetic (relativistic) test particles in simulation snapshots to conduct a detailed investigation on particle diffusion and stochastic acceleration. We consider different amount of net vertical magnetic flux to achieve different disk magnetizations levels at saturated states, with sufficiently high resolution to resolve the gyro-radii ($R_g$) of most particles. Particles with large $R_g$ ($\gtrsim0.03$ disk scale height $H$) show spatial diffusion coefficients of $\sim30$ and $\sim5$ times Bohm values in the azimuthal and poloidal directions, respectively. We further measure particle momentum diffusion coefficient $D(p)$ by applying the Fokker-Planck equation to particle momentum evolution. For these particles, contribution from turbulent fluctuations scales as $D(p)\propto p$, and shear acceleration takes over when $R_g\gtrsim0.1H$, characterized by $D(p)\propto p^3$. For particles with smaller $R_g$ ($\lesssim0.03H$), their spatial diffusion coefficients roughly scale as $\sim p^{-1}$, and show evidence of $D(p)\propto p^2$ scaling in momentum diffusion but with large uncertainties. We find that multiple effects contribute to stochastic acceleration/deceleration, and the process is also likely affected by intermittency in the MRI turbulence. We also discuss the potential of accelerating PeV cosmic-rays in hot accretion flows around supermassive black holes.

The Depoliticisation and ‘ASEANisation’ of Counter-Terrorism Policies in South-East Asia: A Weak Trigger for a Fragmented Version of Human Security
Creators: name: Gerstl, Alfred
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2010

description: This article applies a modified version of the theoretical approach of the Copenhagen School to demonstrate that the Association of Southeast Asian Nations (ASEAN) has since 2001 reacted in a twofold way to the complex political obstacles to closer counter-terrorism co-operation: First, it has responded with securitising terrorism as a transnational crime and, second, with a depoliticisation and ‘ASEANisation’ of its counter-terrorism policies. Depoliticisation and ‘ASEANisation’, i.e. the framing of a security threat under the ASEAN Way values, are both deliberate political actions. They enable politicians to base co-operation among the ASEAN members and with outside powers on a non-political, technical basis. Contradicting an assumption of the Copenhagen School, this study argues that in South-East Asia where sovereignty and non-interference are still core principles this approach can offer better political opportunities to resolve a security threat than a ‘classic’ securitisation. Furthermore, this article demonstrates that ASEAN’s anti-terrorism policies reflect its fragmented version of human security, which is based on national and regime rather than individual security. As counter-terrorism does not enjoy political priority in the region, these policies can only be a weak trigger for the implementation of ASEAN’s notion of human security.

Q-modules are Q-suplattices

description: It is well known that the internal suplattices in the topos of sheaves on a locale are precisely the modules on that locale. Using enriched category theory and a lemma on KZ doctrines we prove (the generalization of) this fact in the case of ordered sheaves on a small quantaloid. Comparing module-equivalence with sheaf-equivalence for quantaloids and using the notion of centre of a quantaloid, we refine a result of F. Borceux and E. Vitale.

A Friend in Need. A Friend in Deed? ASEAN-EU Interregionalism in the Light of Non-Traditional Security Crises in South-East Asia
Creators: name: Maier-Knapp, Naila
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2010

description: The aim of this article is to assess the European Union’s (EU) engagement with and within the Association of Southeast Asian Nations (ASEAN) member states in the field of non-traditional security (NTS) between 1997 and 2009, prior to the Lisbon Treaty becoming effective. The analysis concentrates on the EU’s response to five NTS crises and the interregional level of interaction from a sector-specific governance and social-constructivist approach. These crises are the avian influenza, the political conflict and the tsunami in Aceh, the Bali bombings and the Asian financial crisis (AFC) in South-East Asia. The case studies illustrate EU NTS action and gauge EU NTS actorness from a South-East Asian perspective to substantiate the EU’s interregional interaction and external actorness quality in specific fields of governance in a region so far away.

Unscreened Coulomb interactions and quantum spin Hall phase in neutral zigzag graphene ribbons

description: A study of the effect of unscreened Coulomb interactions on the quantum spin Hall (QSH) phase of finite-width neutral zigzag graphene ribbons is presented. By solving a tight-binding Hamiltonian that includes the intrinsic spin-orbit interaction (I-SO), exact expressions for band-structures and edge-states wavefunctions are obtained. These analytic results, supported by tight-binding calculations, show that chiral spin-filtered edge states are composed of localized and damped oscillatory wavefunctions, reminiscent of the ones obtained in armchair ribbons. The addition of long-range Coulomb interactions opens a gap in the charge sector with a gapless spin sector. In contrast to armchair terminations, the charge-gap vanishes exponentially with the ribbon width and its amplitude and decay-length are strongly dependent on the I-SO coupling. Comparison with reported ab-initio calculations are presented.

Investigation of bond of deformed bars in plain and steel-fiber-reinforced concrete under reversed cyclic loading
Creators: name: Panda, A. K.
Publisher: name: University of British Columbia
Year: 2010

description: The influence of reversed low cyclic loading on the bond behaviour of deformed bars in plain as well as steel-fiber-reinforced concrete has been studied experimentally and is discussed in this thesis. In total, ten specimens consisting of two plain concrete and eight steel-fiber reinforced specimens were tested to failure. The variables were the mix proportions, the size and shape of the steel fibers and the pattern of loading. The results indicate that the most important factor affecting bond or stress transfer is the peak stress reached in the previous cycle. It was observed that steel-fiber-reinforced concrete exhibits higher bond strength, improved stiffness and less bond-deterioration under reversed cyclic loading than plain concrete. It was also found that steel fibers make a definite contribution to crack control and better serviceability.
High-speed Jet Formation after Solid Object Impact

description: A circular disc impacting on a water surface creates a remarkably vigorous jet. Upon impact an axisymmetric air cavity forms and eventually pinches off in a single point halfway down the cavity. Immediately after closure two fast sharp-pointed jets are observed shooting up- and downwards from the closure location, which by then has turned into a stagnation point surrounded by a locally hyperbolic flow pattern. This flow, however, is {\it not} the mechanism feeding the two jets. Using high-speed imaging and numerical simulations we show that jetting is fed by the local flow around the base of the jet, which is forced by the colliding cavity walls. Based on this insight, we then show how the analytical description of a collapsing void (using a line of sinks along the axis of symmetry) can be continued beyond the time of pinch-off to obtain a quantitative model for jet formation which is in good agreement with the numerical and experimental data.
