description: In this PhD thesis, we analyze and generalize the renormalization group approach to the resummation of large logarithms in the perturbative expansion due to soft and collinear multiparton emissions. In particular, we present a generalization of this approach to prompt photon production. It is interesting to see that also with the more intricate two-scale kinematics that characterizes prompt photon production in the soft limit, it remains true that resummation simply follows from general kinematic properties of the phase space. Also, this approach does not require a separate treatment of individual colour structures when more than one colour structure contributes to fixed order results. However, the resummation formulae obtained here turn out to be less predictive than previous results: this depends on the fact that here neither specific factorization properties of the cross section in the soft limit is assumed, nor that soft emission satisfies eikonal-like relations. We also derive resumation formulae to all logarithmic accuracy and valid for all values of rapidity for the prompt photon production and the Drell-Yan rapidity distributions. We show that for the fixed-target experiment E866/NuSea, the NLL resummation corrections are comparable to NLO fixed-order corrections and are crucial to obtain agreement with the data. Finally we outline also possible future applications of the renormalization group approach.

Description. Psolidium species up to 13 mm long (preserved); dorsal and lateral scales up to 2.0 mm wide, scales each with numerous blunt calcareous vertical projections; dorsal and lateral tube feet not conspicuous amongst projections.
Sole with peripheral band of tube feet, single outer series of smaller tube feet, inner single series of larger ones; lacking mid-ventral radial series of tube feet.
Dorsal and lateral ossicles: single to multi-layered perforated plates (scales), lace-like secondary surface developments to multi-layering, tube foot canals; each scale with numerous thick, bulbous calcareous spires, constricted basally, rounded distally, about 200 μ m high, 136 μ m widest diameter, finely spinous surface; irregular branched pointed rod “thorn” ossicles, up to 160 μ m long; shallow concave cups, perforations large, typically 4 around central cross, frequently 4 smaller corner perforations, cups knobbed around margin and on cross, cups typically 120 μ m long; lacking rosettes.
Sole ossicles: shallow concave cups, perforations large, typically 4 around central cross, frequently 4 smaller corner perforations, cups knobbed around margin and on cross, cups typically 112 μ m long; “thorn” ossicles up to 96 μ m long; lacking rosettes.
Colour (preserved). White dorsally, laterally, ventrally.
Distribution. Indonesia (Banda Sea), Arafura Sea, to NW Western Australia (Ningaloo North); 95– 487 m.
Remarks. Tube feet pass through the dorsal and lateral scales of Psolus parmatus Sluiter, 1901. The species is re-assigned here to Psolidium Ludwig. The distinctive species characteristic of Psolidium parmatus (Sluiter) is the presence of numerous blunt vertical calcareous projections on each of the dorsal and lateral scales. These projections resemble “shields” in profile, and hence the species name chosen by Sluiter (parma, Latin for “small shield”).

description: Nanocrystalline Al-doped nickel ferrite powders have been synthesized by sol-gel auto-ignition method and the effect of non-magnetic aluminum content on the structural and magnetic properties has been studied. The X-ray diffraction (XRD) revealed that the powders obtained are single phase with inverse spinel structure. The calculated grain sizes from XRD data have been verified using transmission electron microscopy (TEM). TEM photographs show that the powders consist of nanometer-sized grains. It was observed that the characteristic grain size decreases from 29 to 6 nm as the non-magnetic Al content increases, which was attributed to the influence of non-magnetic Al concentration on the grain size. Magnetic hysteresis loops were measured at room temperature with a maximum applied magnetic field of 1T. As aluminum content increases, the measured magnetic hysteresis curves become more and more narrow and the saturation magnetization and remanent magnetization both decreased. The reduction of agnetization compared to bulk is a consequence of spin non-collinearity. Further reduction of magnetization with increase of aluminum content is caused by non-magnetic Al^{3+} ions and weakened interaction between sublattices. This, as well as the decrease in hysteresis was understood in terms of the decrease in particle size.

description: The runaway greenhouse represents the ultimate climate catastrophe for rocky, Earth-like worlds: when the incoming stellar flux cannot be balanced by radiation to space, the oceans evaporate and exacerbate heating, turning the planet into a hot wasteland with a steam atmosphere overlying a possibly molten magma surface. The equilibrium state beyond the runaway greenhouse instellation limit depends on the radiative properties of the atmosphere and its temperature structure. Here, we use 1-D radiative-convective models of steam atmospheres to explore the transition from the tropospheric radiation limit to the post-runaway climate state. To facilitate eventual simulations with 3-D global circulation models, a computationally efficient band-grey model is developed, which is capable of reproducing the key features of the more comprehensive calculations. We analyze two factors which determine the equilibrated surface temperature of post-runaway planets. The infrared cooling of the planet is strongly enhanced by the penetration of the dry adiabat into the optically thin upper regions of the atmosphere. In addition, thermal emission of both shortwave and near-IR fluxes from the hot lower atmospheric layers, which can radiate through window regions of the spectrum, is quantified. Astronomical surveys of rocky exoplanets in the runaway greenhouse state may discriminate these features using multi-wavelength observations.

description: A water-free, ternary solvent mixture consisting of a natural deep eutectic solvent (NADES), ethanol, and triacetin was investigated concerning its ability to dissolve and extract curcumin from Curcuma longa L. To this purpose, 11 NADES based on choline chloride, acetylcholine, and proline were screened using UV–vis measurements. A ternary phase diagram with a particularly promising NADES, based on choline chloride and levulinic acid was recorded and the solubility domains of the monophasic region were examined and correlated with the system’s structuring via light scattering experiments. At the optimum composition, close to the critical point, the solubility of curcumin could be enhanced by a factor of >1.5 with respect to acetone. In extraction experiments, conducted at the points of highest solubility and evaluated via HPLC, a total yield of ~84% curcuminoids per rhizome could be reached. Through multiple extraction cycles, reusing the extraction solvent, an enrichment of curcuminoids could be achieved while altering the solution. When counteracting the solvent change, even higher concentrated extracts can be obtained.

description: The wave function of a non-relativistic particle in a periodic potential admits oscillatory solutions, the Bloch waves. In the presence of a random noise contribution to the potential the wave function is localized. We outline a new proof of this Anderson localization phenomenon in one spatial dimension, extending the classical result to the case of a periodic background potential. The proof makes use of techniques previously developed to study the effects of noise on reheating in inflationary cosmology, employing methods of random matrix theory.

description: The calculus of variations is a field of mathematical analysis born in 1687 with Newton's problem of minimal resistance, which is concerned with the maxima or minima of integral functionals. Finding the solution of such problems leads to solving the associated Euler-Lagrange equations. The subject has found many applications over the centuries, e.g., in physics, economics, engineering and biology. Up to this moment, however, the theory of the calculus of variations has been confined to Newton's approach to calculus. As in many applications negative values of admissible functions are not physically plausible, we propose here to develop an alternative calculus of variations based on the non-Newtonian approach first introduced by Grossman and Katz in the period between 1967 and 1970, which provides a calculus defined, from the very beginning, for positive real numbers only, and it is based on a (non-Newtonian) derivative that permits one to compare relative changes between a dependent positive variable and an independent variable that is also positive. In this way, the non-Newtonian calculus of variations we introduce here provides a natural framework for problems involving functions with positive images. Our main result is a first-order optimality condition of Euler-Lagrange type. The new calculus of variations complements the standard one in a nontrivial/multiplicative way, guaranteeing that the solution remains in the physically admissible positive range. An illustrative example is given.

name: Tahan, Mohammad
Publisher: name: Journal of Clinical & Developmental Psychology
Year: 2019

description: Aim: The purpose of this study was to investigate the effectiveness of gardener therapist on behavioral problems of slow-step children.


Methods: This was a semi-experimental design research study with pre-test and post-test design with control group. The statistical population included all the slow-step students in the step-by-step educational program of Ramadan in Mash city in 2017, in which 30 students were accessible by method. The title of the research was selected. Subjects were randomly assigned into experimental and control groups (15 experimental and 15 control groups). At first, their instructor completed the Conner's Behavioral Problem Questionnaire (instructor's form) (pre-test). Subsequently, the experimental group was exposed to 12 sessions of the therapist for the period of 45 minutes per week. Instructor again filled the questionnaire at the end and after two weeks, for both groups (post-test). The data were analyzed with the help of covariance analysis.


Results: The results showed that the observed difference between the mean scores of behavioral problems of the participants in the experimental and control group according to the group membership in the post-test stage was considerably significant with 99% confidence interval. The effect of the intervention was 88%.


Conclusion: Gardener therapy is effective on the behavioral problems of slow-graded students and it can be used as a therapeutic tool.

description: We have developed an analytical model of angle-dependent magnetoresistance oscillations (AMROs) in a quasi-two-dimensional metal in which magnetic breakdown occurs. The model takes account of all the contributions from quasiparticles undergoing both magnetic breakdown and Bragg reflection at each junction and allows extremely efficient simulation of data which can be compared with recent experimental results on the organic metal kappa-ET2Cu(NCS)2. AMROs resulting from both closed and open orbits emerge naturally at low field, and the model enables the transition to breakdown-AMROs with increasing field to be described in detail.

The partial characterization of cellulases from Cellulomonas fimi
Creators: name: Langsford, Maureen Lynn
Publisher: name: University of British Columbia
Year: 2010

description: The cellulases of C. fimi have been partially characterized. The extracellular CMCase had optimal activity at pH 7.0 and 52°C. However, the enzyme was not stable at high temperatures. Since the enzyme was inactivated more slowly at lower temperatures, subsequent CMCase activity was determined at 37°C. CMCase was inducible by cellulose and appeared to be regulated by catabolite repression. When cultures were grown on glucose or cellobiose in the presence of inducing levels of cellulose, no cellulase was detected. CMC induced lower levels of CMCase and fewer proteins than did avicel. Analysis by non-denaturing PAGE revealed that CMC-induced cellulases had mobilities different from avicel-induced cellulases. CMCase in culture supernatants continued to increase during growth for 9 days on CMC or avicel. In older cultures, the active components had faster mobilities on polyacrylamide gels. The cellulases of C. fimi are probably derived from only 3-4 gene products. The apparent multiplicity of components may be the result of enzymatic modification, stoichiometric differences in complex formation, or variation in enzyme affinity for substrate.
On the Direction of Casimir Forces
Creators: name: Schaden, Martin
Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The Casimir force due to a massless scalar field satisfying Dirichlet boundary conditions may attract or repel a piston in the neck of a flask-like container. Using the world-line formalism this behavior is related to the competing contribution to the interaction energy of two types of Brownian bridges. It qualitatively is also expected from attractive long-range two-body forces between constituents of the boundary. A geometric subtraction scheme is presented that avoids divergent contributions to the interaction energy and classifies the Brownian bridges that contribute to the force. These are all of finite length and the Casimir force can be analyzed and in principle accurately computed without resorting to regularization or analytic continuation. The world-line analysis is robust with respect to variations in the shape of the piston and the flask and the analogy with long-range forces suggests that neutral atoms and particles are also drawn into open-ended pipes (or nano-tubes) by Casimir forces of electromagnetic origin.

Dirty-paper Coding without Channel Information at the Transmitter and Imperfect Estimation at the Receiver

Year: 2007
Subjects: subject: Information Theory (cs.IT)

description: In this paper, we examine the effects of imperfect channel estimation at the receiver and no channel knowledge at the transmitter on the capacity of the fading Costa's channel with channel state information non-causally known at the transmitter. We derive the optimal Dirty-paper coding (DPC) scheme and its corresponding achievable rates with the assumption of Gaussian inputs. Our results, for uncorrelated Rayleigh fading, provide intuitive insights on the impact of the channel estimate and the channel characteristics (e.g. SNR, fading process, channel training) on the achievable rates. These are useful in practical scenarios of multiuser wireless communications (e.g. Broadcast Channels) and information embedding applications (e.g. robust watermarking). We also studied optimal training design adapted to each application. We provide numerical results for a single-user fading Costa's channel with maximum-likehood (ML) channel estimation. These illustrate an interesting practical trade-off between the amount of training and its impact to the interference cancellation performance using DPC scheme.

description: Background: The first aim of the present study was to investigate differences and similarities in perceived parenting styles between fathers and mothers in the same family. Secondarily, this study wanted to verify the relation between parental anxiety and parenting dimensions, assuming differences according to the parental gender.


Methods: The 80 parents of 40 school-age children independently completed the Parenting Styles and Dimensions Questionnaire (PSDQ), the Parenting Instrument (PI) and the State Trait Anxiety Inventory (STAI).


Results: revealed differences between fathers and mothers in almost all the variables considered, with mothers who reported the highest scores. Significant correlations between paternal and maternal perceptions were found in authoritarian style and in the practices of psychological control (disappointing and shaming). Finally, parental anxiety was associated positively with authoritarian style and inadequate parental practices, and negatively with authoritative style, expressive warmth and supportive involvement: the constructs however correlated in a different way according to parental gender.


Conclusions: Independent assessment of both mother’s and father’s parenting styles and, especially, parental practices of psychological control seem to be necessaries both in research and practical settings.

Land use trends and the influence of orchard management on the soils in Creston, B.C.
Creators: name: Murphy, Kevin James Douglas
Publisher: name: University of British Columbia
Year: 2010

description: The effects of apple orchard management on soil morphology and fertility were examined by comparing the soil under native coniferous vegetation with the soil in the orchard. In 50 years, irrigation and fertilization of the grassed orchard soils in Creston, British Columbia has provided a much greater supply of readily decomposable organic litter than the forest had provided in hundreds of years. A Sombric Brunisol has evolved from a Dystric Brunisol in the sandy glaciofluvial material of the Elmo soil series and a Dark Gray Luvisol has developed in the site originally occupied by the Lister soil series Orthic Gray Luvisol. Through orchard management, total carbon, total nitrogen and extractable phosphorus were enhanced in the surface soil of both orchard sites. The greater amount of organic matter and extractable phosphorus in the Elmo soil orchard site was the major feature distinguishing the orchard from the forest site. Within the orchard site a concentration of cations at the surface and a depletion between 30 and 60 cm characterized the soil inside the orchard dripline. In general, samples collected within the dripline of the sandy orchard soil represented a different population than samples collected outside the dripline. In addition to more carbon, nitrogen and extractable phosphorus, a greater level of exchangeable bases was found at most sample depths in the Lister soil orchard site. This was foreshadowed by field observations indicating that up to 10 centimeters of surface soil had been eroded or removed from the orchard soil, thereby reducing the depth to the calcareous parent material. In contrast to the differences observed across the dripline in the sandy soil, little or no difference in soil chemical properties was noted across the dripline in the heavier textured Lister soil series. Since Creston represents one of the very few areas in Canada capable of producing tree fruits the changes that have taken place since 1950 in land use and orchard productivity were investigated. By diminishing the tonnage of fruit produced, the loss of orchard land to subdivisions prior to 1972 poses a threat to the continuation of a viable fruit industry. However, an uncertain market and low returns to the growers appear to play a greater role in land use allocation in Creston than does urban encroachment. A drop in total apple production in Creston since 1950 was credited to the loss of 190 hectares of orchard land. Through better space utilization and earlier bearing, new semi-dwarf tree plantings that are beginning to produce fruit will aid in surpassing the 1950 production value.

A methodology for structured software development is proposed, which is based on structured analysis of data, represented as Jackson diagrams. It is shown that this analysis allows a straightforward modularisation, and that individual modules may be represented with indentation in the block-structured form of structured programs. The benefits of structured format are discussed, in terms of comprehensibility, ease of maintenance, and reduction in errors. The capability of the methodology to provide a modular overview in the model is described, and examples are given. The potential for a reverse-engineering tool, to transform existing spreadsheet models is discussed.

description: We present the results of the first long-term (2.2 years) spectroscopic monitoring of a gravitationally lensed quasar, namely the Einstein Cross Q2237+0305. The goal of this paper is to present the observational facts to be compared in follow-up papers with theoretical models to constrain the inner structure of the source quasar. We spatially deconvolve deep VLT/FORS1 spectra to accurately separate the spectrum of the lensing galaxy from the spectra of the quasar images. Accurate cross-calibration of the 58 observations at 31-epoch from October 2004 to December 2006 is carried out with non-variable foreground stars observed simultaneously with the quasar. The quasar spectra are further decomposed into a continuum component and several broad emission lines to infer the variations of these spectral components. We find prominent microlensing events in the quasar images A and B, while images C and D are almost quiescent on a timescale of a few months. The strongest variations are observed in the continuum of image A. Their amplitude is larger in the blue (0.7 mag) than in the red (0.5 mag), consistent with microlensing of an accretion disk. Variations in the intensity and profile of the broad emission lines are also reported, most prominently in the wings of the CIII] and center of the CIV emission lines. During a strong microlensing episode observed in June 2006 in quasar image A, the broad component of the CIII] is more highly magnified than the narrow component. In addition, the emission lines with higher ionization potentials are more magnified than the lines with lower ionization potentials, consistent with the results obtained with reverberation mapping. Finally, we find that the V-band differential extinction by the lens, between the quasar images, is in the range 0.1-0.3 mag.

Since the Reynolds number of microscopic flows is very small on the scale of individual agents, inertial effects are typically excluded in continuum theories of active nematic turbulence. Whether active stresses can collectively excite inertial flows is currently unclear. To address this question, we investigate a two-dimensional continuum theory for active nematic turbulence. In particular, we compare mesoscale turbulence with and without the effects of advective inertia. We find that inertial effects can influence the flow already close to the onset of the turbulent state and, moreover, give rise to large-scale fluid motion for strong active driving. A detailed analysis of the kinetic energy budget reveals an energy transfer to large scales mediated by inertial advection. While this transfer is small in comparison to energy injection and dissipation, its effects accumulate over time. The inclusion of friction, which is typically present in experiments, can compensate for this effect. The findings suggest that the inclusion of inertia and friction may be necessary for dynamically consistent theories of active nematic turbulence.

description: We describe a setup which will allow extend the physics reach of the STAR detector at RHIC to include the measurement of very forward protons. Tagging on very forward protons, detected by the Roman Pots at RHIC energies, selects processes, in which the proton stays intact and the exchange is dominated by one with the quantum numbers of the vacuum, thus enhancing the probability of measuring reactions where colorless gluonic matter dominates the exchange. The processes include both elastic and inelastic diffraction. The capabilities of the STAR detector to detect Gleuballs and Exotics in central production mechanism are described.

description: We present the Swimmy (Subaru WIde-field Machine-learning anoMalY) survey program, a deep-learning-based search for unique sources using multicolored ($grizy$) imaging data from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). This program aims to detect unexpected, novel, and rare populations and phenomena, by utilizing the deep imaging data acquired from the wide-field coverage of the HSC-SSP. This article, as the first paper in the Swimmy series, describes an anomaly detection technique to select unique populations as "outliers" from the data-set. The model was tested with known extreme emission-line galaxies (XELGs) and quasars, which consequently confirmed that the proposed method successfully selected 60-70% of the quasars and 60% of the XELGs without labeled training data. In reference to the spectral information of local galaxies at $z=$0.05-0.2 obtained from the Sloan Digital Sky Survey, we investigated the physical properties of the selected anomalies and compared them based on the significance of their outlier values. The results revealed that XELGs constitute notable fractions of the most anomalous galaxies, and certain galaxies manifest unique morphological features. In summary, a deep anomaly detection is an effective tool that can search rare objects, and ultimately, unknown unknowns with large data-sets. Further development of the proposed model and selection process can promote the practical applications required to achieve specific scientific goals.

description: We use a new set of Collins functions to update a previous prediction on the azimuthal asymmetries of pion productions in semi-inclusive deep inelastic scattering (SIDIS) process on a transversely polarized nucleon target. We find that the calculated results can give a good explanation to the HERMES experiment with the new parametrization, and this can enrich our knowledge of the fragmentation process. Furthermore, with two different approaches of distribution and fragmentation functions, we present a prediction on the azimuthal asymmetries of pion and kaon productions at the kinematics region of the experiments E06010 and E06011 planned at Jefferson Lab (JLab). It is shown that the results are insensitive to the models for the pion case. However, the results for kaon production are sensitive to different approaches of distribution and fragmentation functions. This is helpful to clarify some points in the study of the azimuthal spin asymmetries and fragmentation functions in hadronization processes.

description: Farming systems (FS) operate in biophysical, political, social, economic and cultural environments which are often far from stable. Frequently or unfavourably changing conditions can affect FS performance, i.e., the delivery of FS functions (such as food production or ecosystem services). The aim of this report is to identify principles for an enabling environment to foster (rather than hinder) resilient farming systems in Europe. Fostering FS resilience is done through (re)designing institutions and building and mobilising resources in order to enhance resilience enabling attributes of FS (and remove resilience constraining attributes). These institutions can be both part of the FS and part of an enabling environment, consisting of private actors (such as food processors, retailers, banks, etc.) and public actors (government agencies). Six general principles underpinning patterns that enable FS resilience have been formulated. An important challenge is that FS and enabling environments should always find a good balance between addressing challenges in the short run and dealing with challenges in the long run.

description: We consider order preserving $C^3$ circle maps with a flat piece, irrational rotation number and critical exponents $(\ell_1, \ell_2)$. We detect a change in the geometry of the system. For $(\ell_1, \ell_2) \in [1,2]^2$ the geometry is degenerate and it becomes bounded for $(\ell_1, \ell_2) \in [2,\infty)^2 \setminus \{(2,2)\}$. When the rotation number is of the form $[abab\cdots]$; for some $a,b\in\mathbb{N}^*$, the geometry is bounded for $(\ell_1, \ell_2)$ belonging above a curve defined on $]1, +\infty [^2$. As a consequence we estimate the Hausdorff dimension of the non-wandering set $K_f= \mathcal{S}^1 \setminus \bigcup_{i=0}^\infty f^{-i}(U)$. Precisely, the Hausdorff dimension of this set is equal to zero when the geometry is degenerate and it is strictly positive when the geometry is bounded.

description: Students learning how to apply spreadsheets to accounting problems are not always well served by the built-in financial functions. Problems can arise because of differences between UK and US practice, through anomalies in the functions themselves, and because the promptings of Wizards' engender an attitude of filling in the blanks on the screen, and hoping for the best. Some examples of these problems are described, and suggestions are presented for ways of improving the situation. Principally, it is suggested that spreadsheet prompts and 'Help' screens should offer integrated guidance, covering some aspects of financial practice, as well as matters of spreadsheet technique.

description: The subject of this contribution is the fragment of an ivory rod with six cuneiform signs that was found in 2002. The rod came to light in a destruction layer dating to LH III B Final within a workshop for skilled crafting inside Building XI which is situated in the northernmost part of the Lower Citadel of Tiryns. The inscription is interpreted as the first example of an Ugaritic text found outside of the Levant. The text is written from left to right combining Akkadian logographic numerical signs and at least one letter of the regular Ugaritic alphabet. After discussing different possibilities concerning the object’s function, an interpretation as a ›tally stick‹ is proposed, i.e. a mnemonic device to document numbers, quantities or possibly a message, that was used by Levantine or Cypriote specialists for skilled crafting who were working in Building XI on behalf of the palace. The find assemblage in Building XI serves as a reminder that it would be highly misleading to regard oriental objects like the ivory rod with cuneiform signs or wall brackets appearing in a Mycenaean harbor town such as Tiryns as mere ›exotica‹. Instead, contextual analysis demonstrates that the users were well aware of the special significance attached to such objects in the east and employed them in accordance with practices of Near Eastern or Cypriote origin, thus signaling their cultural affiliations.

description: Increasing amounts of freely available data both in textual and relational form offers exploration of richer document representations, potentially improving the model performance and robustness. An emerging problem in the modern era is fake news detection -- many easily available pieces of information are not necessarily factually correct, and can lead to wrong conclusions or are used for manipulation. In this work we explore how different document representations, ranging from simple symbolic bag-of-words, to contextual, neural language model-based ones can be used for efficient fake news identification. One of the key contributions is a set of novel document representation learning methods based solely on knowledge graphs, i.e. extensive collections of (grounded) subject-predicate-object triplets. We demonstrate that knowledge graph-based representations already achieve competitive performance to conventionally accepted representation learners. Furthermore, when combined with existing, contextual representations, knowledge graph-based document representations can achieve state-of-the-art performance. To our knowledge this is the first larger-scale evaluation of how knowledge graph-based representations can be systematically incorporated into the process of fake news classification.
Theory of biphoton generation in a single-resonant optical parametric oscillator far below threshold

description: We present a quantum-theoretical treatment of biphoton generation in single-resonant type-II parametric down-conversion. The nonlinear medium is continuously pumped and is placed inside a cavity which is resonant for the signal field, but nonresonant for the idler deflected by an intra-cavity polarizing beam splitter. The intensity of the classical pump is assumed to be sufficiently low in order to yield a biphoton production rate that is small compared to the cavity loss rate. Explicit expressions are derived for the rate of biphoton generation and for the biphoton wave function. The output spectra of the signal and idler field are determined, as well as the second-order signal-idler cross-correlation function which is shown to be asymmetric with respect to the time delay. Due to frequency entanglement in the signal-idler photon pair, the idler spectrum is found to reveal the longitudinal mode structure of the cavity, even though the idler field is not resonant.
