description: This paper presents a novel data-driven approach to mitigating employee attrition using machine learning and data engineering techniques. The proposed framework integrates data from various human resources systems and leverages advanced feature engineering to capture a comprehensive set of factors influencing attrition. The study outlines a robust modeling approach that addresses challenges such as imbalanced datasets, categorical data handling, and model interpretation. The methodology includes careful consideration of training and testing strategies, baseline model establishment, and the development of calibrated predictive models. The research emphasizes the importance of model interpretation using techniques like SHAP values to provide actionable insights for organizations. Key design choices in algorithm selection, hyperparameter tuning, and probability calibration are discussed. This approach enables organizations to proactively identify attrition risks and develop targeted retention strategies, ultimately redu

description: Swarm User Interfaces allow dynamic arrangement of user environments through the use of multiple mobile robots, but their operational range is typically confined to a single plane due to constraints imposed by their two-wheel propulsion systems. We present corobos, a proof-of-concept design that enables these robots to cooperatively transition between table (horizontal) and wall (vertical) surfaces seamlessly, without human intervention. Each robot is equipped with a uniquely designed slope structure that facilitates smooth rotation when another robot pushes it toward a target surface. Notably, this design relies solely on passive mechanical elements, eliminating the need for additional active electrical components. We investigated the design parameters of this structure and evaluated its transition success rate through experiments. Furthermore, we demonstrate various application examples to showcase the potential of corobos in enhancing user environments.

Diagnosis: **
 Characters somewhat similar to Aphelenchus parietinus Bastian but with these differences: Body only. 31 mm. in length. Spear much larger with distinct trilobed base. Tail ending in a mucro formed by a sudden contraction of the terminus.
* For explanation of the decimal formula, Cobb. in these Transactions, Vol. XXXIII, see page 73.
** The “ Diagnosis” includes the decimal formula of the measurements of the species and the ﬁrst paragraph following the formula. The additional paragraphs give general, but not speciﬁc, information.
The transverse stiae are exceedingly ﬁne, being scarcely visible. There are two very indistinct wings. The lip region is set off and has a cutinous framework about the entrance to the pharynx. A narrow vestibule reaches half the spear length, at its base forming an indistinct guiding ring for the spear. The median bulb is as long as the neck width and almost as wide as the body cavity with a conspicuous valvular apparatus near its center. The nerve ring encircles the narrow tube leading from the bulb to the intestine one body width below the bulb. The renette pore is opposite the nerve ring. The anus is distinct and from it the slender rectum extends forward two anal body-widths. A prominent feature is a ventral narrowing of the body just posterior to the elevated vulva. Whe anterior ovary is out-stretched the posterior rudimentary and only three body-widths long. Eggs are three times as long as the vulva body-width and ﬁll the body cavity.
Five specimens, all of which are adult females.

Policy and legal framework for green technology innovation funding and governance - the case of Malaysia
Creators: name: Silivarajoo, Punitha
Publisher: name: Imperial College London
Year: 2017

description: This research proposes a Policy and Legal Framework for Green Technology Innovation for Malaysia, focusing on (i) Funding and Financing and (ii) Governance and Institutional Mechanisms. The concept of Green Technology gained attention in Malaysia in 2009 after the inception of the National Green Technology Policy and the establishment of a dedicated Ministry that oversees Green Technology. The motivation for the scope of this research was a result of the emphasis placed by the National Green Technology Policy on the area of Research, Development and Innovation (RD&I), as a strategic thrust that could contribute to the development and application of Green Technology in Malaysia. However, preliminary research reveals existing issues with the governance and institutional mechanisms, where there is a lack of policy coherence, institutional gaps, and jurisdictional discrepancies that hinder implementation of Green Technology and Green Growth measures in Malaysia. The researcher, through this research, identifies the gaps and discrepancies, provides justifications for strategic actions and recommends a comprehensive policy and legal framework with an Implementation Guide for Green Technology Innovation, specifically focusing on funding and financing and governance and institutional mechanisms. This research is purely qualitative which derives best practices and qualitative data from case studies. To support the validity of the research findings, interview sessions were conducted in the European Commission, relevant agencies in South Korea and Malaysia. A survey was administered amongst the key players of the innovation ecosystem in Malaysia that derived qualitative data which was used to strengthen the data on the current scenario in Malaysia. A case study analysis of the policies and legal interventions employed in the European Union, South Korea and Malaysia were used to support the findings of this research further. In addition to the recommendations and an implementation guide, a Multi-Criteria Framework was developed to assist in prioritising Green Technologies for funding and financing decision making. This research hopes to unveil the issues indicated above with suitable recommendations that could assist in reducing the barriers and limitations faced by Malaysia in achieving its goal of being a sustainable and inclusive High-Income Nation.

description: Patterns of taxonomic and phylogenetic beta diversity and their relationships with environmental correlates can help reveal the origin and evolutionary history of regional biota. The Qinghai-Tibet Plateau (QTP) harbors an exceptionally diverse flora, however, a phylogenetic perspective has rarely been used to investigate its beta diversity and floristic regions. In this study, we used a phylogenetic approach to identify patterns of beta diversity and quantitatively delimit floristic regions on the Qinghai-Tibet Plateau. We also examined the relationships between multifaceted beta diversity, geographical distance, and climatic difference, and evaluated the relative importance of various factors (i.e., climate, topography and history) in shaping patterns of beta diversity. Sørensen dissimilarity indices indicated that patterns of species turnover among sites dominated the QTP. We also found that patterns of both taxonomic and phylogenetic beta diversity were significantly related to geographical distance and climatic difference. The environmental factors that contributed most to these patterns of beta diversity include annual precipitation, mean annual temperature, climatic gradients and climatic instability. Hierarchical dendrograms of dissimilarity and non-metric multidimensional scaling ordination based on phylogenetic beta diversity data identified ten floristic subregions in the QTP. Our results suggest that the contemporary environment and historical climate changes have filtered species composition among sites and eventually determined beta diversity patterns of plants in the QTP.
Translating specialized metaphors in technical discourse: an analysis of 'Foundations of Engineering' and its Malay translation 'Asas Kejuruteraan'
Creators: name: Abdullah, Sharmini
Publisher: name: Imperial College London
Year: 2017

description: This doctoral study explores whether engineering metaphors are used in the translation of an engineering text from English to Malay and examines how the usage of metaphors in the target text (TT) compares to that in the source text (ST). The study focuses on Holtzapple and Reese’s “Foundations of Engineering” and its Malay version “Asas Kejuruteraan” translated by Juneta Zawawi. The “Metaphor Identification Procedure” (MIP) by the Pragglejaz Group is applied in the process of gathering examples while the Cognitive Metaphor Theory is used for the purposes of metaphor analysis. A combination of Newmark’s (1988), Deignan’s (2005) and Lakoff and Johnson’s (1980) classifications of metaphor are used to categorize the SL and TL metaphorical expressions. Metaphor translation procedures identified were benchmarked to those proposed by Newmark (1988). Analysis of the 174 ST and 82 TT engineering metaphors reveals that the use of metaphorical language does indeed characterize the English technical text and its translation into Malay. Identifying equivalence in the TL discloses somewhat similar problems to those that are present in literary metaphor translation. The ease of translation and the identification of suitable engineering metaphors are not determined solely by the type of metaphor but rather are also partially dependent on cultural and linguistic factors. Metaphor translation procedures as outlined by Newmark are found to be unable to account for all the examples, which results in the creation of the two variants of one of his translation procedures, the proposal of three new ones that are identified and the abandonment of two of his procedures. The selection of translation procedure appears to be dependent not only on the metaphor type but also on whether the translator simply decides to use equivalent SL metaphors or non-metaphorical expressions in the TL. It is also highly likely that the type of text being translated plays a role.

description: We present a digital catalog of images of 113 galaxies in this paper. These galaxies are all nearby, bright, large and well resolved. All images were recorded with charge coupled devices (CCDs) at the Palomar Observatory with the 1.5 meter telescope and at the Lowell Observatory with the 1.1 meter telescope. At Palomar we used the Thuan--Gunn g, r and i photometric bands to take 3 images each of 31 spiral galaxies; at Lowell we used the B_J and R bands (2 images per galaxy) of the photometric system by Gullixson et al. (1995) to observe 82 spirals and ellipticals. The galaxies were selected to span the Hubble classification classes. All data are photometrically calibrated with foreground stars removed. Important data on these galaxies published in the "Third Reference Catalog of Bright Galaxies" (RC3) are recorded in the FITS file headers. All files are available through anonymous FTP from ftp://astro.princeton.edu/, through WWW at http://astro.princeton.edu/~frei/galaxy_catalog.html, and Princeton University Press will soon publish the data on CD-ROM.

Irreversibility in active matter systems: Fluctuation theorem and mutual information

description: We consider a Brownian particle which, in addition to being in contact with a thermal bath, is driven by fluctuating forces which stem from active processes in the system, such as self-propulsion or collisions with other active particles. These active fluctuations do not fulfill a fluctuation-dissipation relation and therefore play the role of a non-equilibrium environment, which keeps the system permanently out of thermal equilibrium even in the absence of external forces. We investigate how the out-of-equilibrium character of the active matter system and the associated irreversibility is reflected in the trajectories of the Brownian particle. Specifically, we analyze the log-ratio of path probabilities for observing a certain particle trajectory forward in time versus observing its time-reversed twin trajectory. For passive Brownian motion, it is well-known that this path probability ratio quantifies irreversibility in terms of entropy production. For active Brownian motion, we show that in addition to the usual entropy produced in the thermal environment the path probability ratio contains a contribution to irreversibility from mutual information production between the particle trajectory and the history of the non-equilibrium environment. The resulting irreversibility measure fulfills an integral fluctuation theorem and a second-law like relation. When deriving and discussing these relations, we keep in mind that the active fluctuations can occur either due to a suspension of active particles pushing around a passive colloid or due to active self-propulsion of the particle itself; we point out the similarities and differences between these two situations. We obtain explicit expressions for active fluctuations modeled by an Ornstein-Uhlenbeck process. Finally, we illustrate our general results by analyzing a Brownian particle which is trapped in a static or moving harmonic potential.

description: The electronic and nuclear dynamics in methanol, following 156~nm photoexcitation, are investigated by combining a detailed analysis of time-resolved photoelectron spectroscopy experiments with electronic structure calculations. The photoexcitation pump pulse is followed by a delayed 260~nm photoionization probe pulse, to produce photoelectrons that are analyzed by velocity map imaging. The yield of mass-resolved ions, measured with similar experimental conditions, are found to exhibit the same time-dependence as specific photoelectron spectral features. Energy-resolved signal onset and decay times are extracted from the measured photoelectron spectra to achieve high temporal resolution, beyond the 20~fs pump and probe pulse durations. When combined with {\it ab initio} calculations of selected cuts through the excited state potential energy surfaces, this information allows the dynamics of the transient excited molecule, which exhibits multiple nuclear and electronic degrees of freedom, to be tracked on its intrinsic few-femtosecond timescale. Within 15~fs of photoexcitation, we observe nuclear motion on the initially bound photoexcited 2$^{1}$A$''$ (S$_2$) electronic state, through a conical intersection with the 1$^{1}$A$'$ (S$_3$) state, which reveals paths to photodissociation following C--O stretch and C--O--H angle opening.

Nonlinear dynamic analysis of large scale structures
Creators: name: Gu, Jiaping
Publisher: name: Imperial College London
Year: 2018

description: The nonlinear dynamic analysis to obtain the response of whole building structures or structural components under blast loading can be computationally prohibitive. Two approaches have been considered in this study to improve the efficiency of such analyses: i) to employ an appropriate time integration scheme and, ii) to employ accurate simplified models of structural components. A new implicit-explicit time integration scheme has been developed and implemented with a novel automatic element-based mesh partitioning approach. The scheme allows simultaneous execution of implicit integration and explicit integration in different parts of a system to maximise computational efficiency. The developed scheme has also been notably incorporated to the novel domain decomposition approach developed previously at Imperial College London. The scheme is also successfully incorporated with the mixed-dimensional coupling technique included in the domain decomposition approach. Simplified models of structural components have been improved for a better representation of responses under blast loading. Mechanical models of fin plate connections have been modified by including material nonlinearity and material strain rate effect in the coupled axial and shear response of bolt rows. The flat shell elements have been verified in their ability to capture the influence of transverse damage in floor slabs due to uplift on the in-plane diaphragm stiffness and strength. These simplified models have been incorporated in the global model of a reference building, which has been analysed and assessed under characteristic blast loading. Typical masonry cavity cladding has been investigated as a case study. The failure mode and the interaction between the cladding and the structural frame have been successfully obtained from mesoscale models employing the mixed-dimensional domain decomposition approach and the implicit-explicit time integration scheme. A SDOF model based on the results of the detailed model has been constructed and incorporated in the global model of the reference building.

The different distribution and motions of these disk stars make their associated microlensing rates and event duration distributions to be quite different from those of the bulge stars. We discuss the uncertainties in these predictions associated to the modeling of the Galactic components and the main implications resulting from the inclusion of this second source population.

description: We report the discovery of two new Wolf-Rayet (WR) galaxies: Mrk~1039, and F08208$+$2816. Two broad WR bumps at 5808Å~ and 4650Å~ indicate the presence of WCE and WNL star population in all two sources. We also confirm the presenceof WR features in Mrk~35, previously detected in a different position. The observed equivalent width of the WR bump at 4650Å~ and the derived number ratios of WR/(WR$+$O) imply that star formation in these sources takes place inshort burst duration. Comparisons with the recent models of WR populations in young starbursts with the observed EW(\HeII)/EW(\CIV)/EW(WRbump) and their relative intensitie provide an indication that the stellar initial mass function in some WR galaxies might not be Salpeter-like. It is interesting to find that the luminous IRAS source, F08208$+$2816, has little dust reddening, probably because of the existence of a powerful superwind. By comparisons with other starbursts observed with the Hopkins Ultraviolet Telescope, F08208$+$2816 as a merging system renders a chance to study the contribution from young starbursts to the UV background radiation in universe.

description: Let $L$ be a finite extension of $\mathbb{Q}_p$ and $n\geq 2$. We associate to a crystabelline $n$-dimensional representation of $\mathrm{Gal}(\overline L/L)$ satisfying mild genericity assumptions a finite length locally $\mathbb{Q}_p$-analytic representation of $\mathrm{GL}_n(L)$. In the crystalline case and in a global context, using the recent results on the locally analytic socle from [BHS17a] we prove that this representation indeed occurs in spaces of $p$-adic automorphic forms. We then use this latter result in the ordinary case to show that certain "ordinary" $p$-adic Banach space representations constructed in our previous work appear in spaces of $p$-adic automorphic forms. This gives strong new evidence to our previous conjecture in the $p$-adic case.

description: Apicobasal ridges are longitudinal ridges of enamel that are particularly common in several clades of aquatic-feeding predatory tetrapods, including Plesiosauria, Ichthyosauria, Mosasauridae, Crocodylia and Spinosauridae, as well as some early members of Cetacea. Although the repeated evolution of these dental ridges in unrelated clades suggests an adaptive benefit, their primary function in feeding is debated. Drawing on morphometric data from fossilized tooth crowns, a set of digital models was constructed to calculate the performance of smooth and ridged tooth variants under simulated bite force loadings through Finite Element Analysis. The morphometric datasets were also statistically analyzed to determine any possible links between phylogeny and apicobasal ridge morphology.

description: The first X-ray observation of the Seyfert 2 galaxy NGC5252 is reported. ASCA collected $\sim 4000$ photons/detector enough to perform an accurate spectral analysis of this source. The luminosity of NGC5252 is L$_{\rm X}$(0.7-10 keV) $\simeq 2.6 \times 10^{43}$ erg s$^{-1}$, typical of a Seyfert 1 galaxy. A simple description of the spectrum with a single power law is ruled out by the SIS data which shows a strong soft excess at E $\lsimeq$ 1.2 keV. The spectrum is best fitted by models assuming either partial covering of the central source or scattering of the X-ray continuum. The best-fit partial covering model results in a flat ($Γ\simeq 1.45 \pm 0.2$) power law continuum emitted by a source almost completely covered (at $\sim$ 94-97\%) by neutral matter ($N_{\rm H} \simeq (4.3 \pm 0.6) \times 10^{22}$ cm$^{-2}$). The detected iron line is remarkably weaker (EW $\sim 90 \pm 60$ eV) than normally found from Seyfert 2 galaxies. In an effort to interpret the observed flat spectrum with an intrinsically steep power law as predicted by unified models, we also included in the models neutral reflection, ionized absorption (warm absorber), and non-uniform cold absorption (dual-absorber). We find that the observed flat continum {\bf and} weakness of the iron line poses a problem for neutral reflection models, whatever the assumed geometry is. The use of an ionized absorber (scattering + warm-absorber model) instead of a neutral absorber seems not justified with the present data. The ``dual-absorber'' model, representing nonuniform (density) absorption along the line of sight, may provide an alternative explanation for the flatness of the spectrum, with no constraints on the Fe K emission line. Another plausible interpretation of the present data is that the X-ray spectrum of NGC5252 is truly intrinsically flat. Its strong

Optical gain and loss in nanophotonics
Creators: name: Nguyen, Ngoc B.
Publisher: name: Imperial College London
Year: 2018

description: The topic of gain/loss and dispersion is fundamental to the construction of various nanophotonic devices. Through a unique branch of physics called Parity Time Symmetry (PTS), the interplay between gain and loss opens many opportunities to make gain/loss and dispersion necessary parts of the operation of PTS optical devices. The spatial refractive index profile of an optical PTS system, n(x,y,z) requires R{n(x,y,z)} to be spatially symmetric and I{n(x,y,z)} to be spatially antisymmetric. Such a system exhibits exceptional point behaviours which give rise to unusual physical phenomena including non-reciprocal propagation of light—the operational principle of optical diodes. Most solid state devices investigated in this thesis are based on GaAs to supply gain. To apply the concept of PTS to practical optical platforms where high loss/gain exists, it is essential to understand the mechanism behind the high gain in GaAs and associated gain-induced dispersion. To assess the feasibility of generating high gain and the extent of dispersion effects in nanooptics, we demonstrate experimentally a practical GaAs plasmonic laser based on the hybrid gap plasmon waveguide. The analysis of the modal gain and losses in these nanolasers suggests that even though lasing actions can be obtained in this high loss environment, the severe effects of dispersion pose potential issues in practical PTS systems. In PTS coupled waveguides, the detrimental influence of gain-induced dispersion is counteracted by working with non-identical waveguides and bias pumping of the optical waveguides. The coupled mode theory provides the necessary formulation for an in-depth analysis of such a highly dispersive system. The useful application of dispersion in optical PTS is investigated in a Silicon-based active PTS grating. The results of these works improve our understanding of the gain/loss and dispersion mechanism in PTS optical devices and lay the foundation for an efficient design of PTS optical diodes.

The high spectral resolution of our Fabry-Perot system allows us to separate the Galactic signal from the much larger local sources of H alpha emission, such as the Earth's geocorona. For the two bands (at declination -62 and -63 degrees), we find a total mean emission of about 1 Rayleigh with variations of about 0.3 R. The variations are within the estimated uncertainty of our total intensity determinations. For an ionized gas at T around 10**4 K, this corresponds to a maximum free-free brightness temperature of less than 10 microK at 30 GHz (K-band). Thus, unless there is a hot gas component with T around 10**6 K, our results imply that there is essentially no free-free contamination of the SP91 (Schuster et al. 1993) and SP94 (Gunderson et al.1995) data sets.

Realisation of a hot carrier photovoltaic cell

Publisher: name: Imperial College London

description: The hot carrier solar cell is a heat engine; supplementing or supplanting the photovoltaic action of a traditional solar cell with a thermally driven current, analogous to a thermoelectric device. With this additional channel for energy extraction it is, in principle, possible for these cells to achieve efficiencies up to 85%, since the thermalization loss of high energy carriers is mitigated through their contribution to the heat current. In this thesis, three different hot carrier solar cell concepts are presented and experimentally investigated to probe their efficacy. Firstly, a hot carrier solar cell structure is presented, in which photogenerated carriers are extracted from a narrow band gap semiconductor to a wider bandgap semiconductor through a double barrier quantum well, providing energy selective extraction through resonant tunnelling. Current-voltage characteristics of this cell are presented along with time-resolved and temperature-dependent photoluminescence data, supporting the conclusion that this cell is operating as a hot carrier cell. Secondly, the idea of a metallic absorber for a solar cell is proposed, in order to provide ultra-high absorption of light (>99%) in metallic films thinner than 10nm. This idea is realised in two different cells, with silver and chromium absorbers. The absorption of light in the metal film, followed by extraction of heated electrons over a Schottky barrier, is demonstrated. Thirdly, the combination of these ideas is discussed, and a solar cell with a metallic absorber and selective extraction of heated electrons through resonant tunneling is realised. The current-voltage characteristics of all cells are modelled theoretically, and key signatures are revealed in both experimental and theoretical work showing the extraction of heated carriers.

description: This paper first introduces China's legal framework regulating facial recognition technology (FRT) and analyzes the underlying problems. Although current laws and regulations have restricted the development of FRT under some circumstances, these restrictions may function poorly when the technology is installed by the government or when it is deployed for the purpose of protecting public security. We use two cases to illustrate this asymmetric regulatory model, which can be traced to systematic preferences that existed prior to recent legislative efforts advancing personal data protection. Based on these case studies and evaluation of relevant regulations, this paper explains why China has developed this distinctive asymmetric regulatory model towards FRT specifically and personally data generally.

description: In this paper, we provide a complete mathematical construction for a stochastic leaky-integrate-and-fire model (LIF) mimicking the interspike interval (ISI) statistics of a stochastic FitzHugh-Nagumo neuron model (FHN) in the excitable regime, where the unique fixed point is stable. Under specific types of noises, we prove that there exists a global random attractor for the stochastic FHN system. The linearization method is then applied to estimate the firing time and to derive the associated radial equation representing a LIF equation. This result confirms the previous prediction in [Ditlevsen, S. and Greenwood, P. (2013). The Morris-Lecar neuron model embeds a leaky integrate-and-fire model.

description: The sheared-flow stabilized $Z$-pinch has demonstrated long-lived plasmas with fusion-relevant parameters. This Letter presents the first experimental results demonstrating sustained, quasi-steady-state neutron production from the Fusion $Z$-pinch Experiment (FuZE), operated with a mixture of 20% deuterium/80% hydrogen by volume. Neutron emissions lasting approximately $5~μ$s are reproducibly observed with pinch currents of approximately $200$ kA during an approximately $16~μ$s period of plasma quiescence. The average neutron yield is estimated to be $\left ( 1.25\pm 0.45 \right )\times 10^{5}$ neutrons/pulse and scales with the square of the deuterium concentration. Coincident with the neutron signal, plasma temperatures of $1-2$ keV, and densities of approximately $10^{17}$ cm$^{-3}$ with $0.3$ cm pinch radii are measured with fully-integrated diagnostics.

description: In a two-dimensional axisymmetric system, a symmetric self-propelled particle exhibits rotational or oscillatory motion from the consideration of the system symmetry. In the present paper, we studied the motion of a camphor disk confined in a two-dimensional circular region. By reducing the mathematical model describing the dynamics of the motion of a camphor disk and the concentration field of camphor molecules on a water surface, we analyzed the reduced equations around a bifurcation point where the rest state at the center of the system becomes unstable. As a result, we found that rotational motion is stably realized through the double-Hopf bifurcation from the rest state. The theoretical results were confirmed by numerical calculation and well corresponded to the experimental results.

description: We construct a quantum Markovian Master equation for a driven system coupled to a thermal bath. The derivation utilizes an explicit solution of the propagator of the driven system. This enables the validity of the Master equation to be extended beyond the adiabatic limit. The Non-Adiabatic Master Equation (NAME) is derived employing the weak system-bath coupling limit. The NAME is valid when a separation of timescales exists between the bath dynamics and the external driving. In contrast to the adiabatic Master equation, the NAME leads to coupled equations of motion for the population and coherence. We employ the NAME to solve the example of an open driven time-dependent harmonic oscillator. For the harmonic oscillator the NAME predicts the emergence of coherence associated with the dissipation term. As a result of the non-adiabatic driving the thermalization rate is suppressed. The solution is compared with both numerical calculations and the adiabatic Master equation.

Warm absorber, reflection and Fe K line in the X-ray spectrum of IC 4329A

description: Results from the X-ray spectral analysis of the ASCA PV phase observation of the Seyfert 1 galaxy IC 4329A are presented. We find that the 0.4 - 10 keV spectrum of IC 4329A is best described by the sum of a steep ($Γ\sim 1.98$) power-law spectrum passing through a warm absorber plus a strong reflection component and associated Fe K line, confirming recent results (Madejski et al. 1995, Mushotsky et al. 1995). Further cold absorption in excess of the Galactic value and covering the entire source is also required by the data, consistent with the edge-on galactic disk and previous X-ray measurements. The effect of the warm absorber at soft X-ray energies is best parameterized by two absorption edges, one consistent with OVI, OVII or NVII, the other consistent with OVIII. A description of the soft excess in terms of blackbody emission, as observed in some other Seyfert 1 galaxies, is ruled out by the data. A large amount of reflection is detected in both the GIS and SIS detectors, at similar intensities. We find a strong correlation between the amount of reflection and the photon index, but argue that the best solution with the present data is that given by the best statistical fit. The model dependence of the Fe K line parameters is also discussed. Our best fit gives a slightly broad ($σ\simeq 0.11 \pm 0.08$ keV) and redshifted (E $\simeq 6.20 \pm 0.07$ keV) Fe K line, with equivalent width $\simeq$ 89 $\pm$ 33 eV. The presence of a weak Fe K line with a strong reflection can be reconciled if one assumes iron underabundances or ionized reflection. We also have modeled the line with a theoretical line profile produced by an accretion disk. This yields results in better agreement with the constraints obtained from the reflection component.
