description: The COVID-19 pandemic considerably affects public health systems around the world. The lack of knowledge about the virus, the extension of this phenomenon, and the speed of the evolution of the infection are all factors that highlight the necessity of employing new approaches to study these events. Artificial intelligence techniques may be useful in analyzing data related to areas affected by the virus. The aim of this work is to investigate any possible relationships between air quality and confirmed cases of COVID-19 in Italian districts. Specifically, we report an analysis of the correlation between daily COVID-19 cases and environmental factors, such as temperature, relative humidity, and atmospheric pollutants. Our analysis confirms a significant association of some environmental parameters with the spread of the virus. This suggests that machine learning models trained on the environmental parameters to predict the number of future infected cases may be accurate. Predictive models may be useful for helping institutions in making decisions for protecting the population and contrasting the pandemic.

description: Ο σκοπός της παρούσας κλινικής έρευνας ήταν να διερευνηθεί και να αξιολογηθεί η επίδραση των ομοιοπαθητικών θεραπευτικών σχημάτων σε ασθενείς με κρανιογναθικές διαταραχές. Η μέθοδος περιελάμβανε: τη συγκέντρωση του προς μελέτη υλικού, το σχηματισμό του ειδικού δείγματος, την εφαρμογή του κατάλληλου ομοιοπαθητικού σχήματος, το πρωτόκολλο επανεξέτασης και καταγραφής του κλινικού δείκτη, την επιλογή των παραμέτρων προς στατιστική αξιολόγηση και τη στατιστική αξιολόγηση. Το υλικό που μελετήσαμε συγκεντρώθηκε από ασθενείς που προσήλθαν στις κλινικές της Ακίνητης Οδοντικής Προσθετικής του Αριστοτέλειου Πανεπιστήμιου Θεσσαλονίκης και οι οποίοι είχαν εξεταστεί για προβλήματα κρανιογναθικών διαταραχών και είχαν αντιμετωπιστεί θεραπευτικά με συντηρητικά θεραπευτικά σχήματα κατά τη χρονική περίοδο 1997-2003. Η ομοιοπαθητική εφαρ-μόστηκε σα συμπληρωματική θεραπεία. Οι ομάδες που σχηματίστηκαν και συγκρίθηκαν ήταν δύο. Η ομάδα Α περιέλαβε ασθενείς με κυρίαρχα τα μυοπροσωπικά συμπτώματα. Η ομάδα Β περιέλαβε δυσλειτουργικούς ασθενείς με κυρίαρχα τα στοιχεία εσωτερικής αποδιοργάνωσης της ΚΓΔ και συνοδούς χρόνιους πονοκεφάλους. Τα αποτελέσματα δεί-χνουν ότι η εφαρμογή του ομοιοπαθητικού θεραπευτικού σχήματος επιφέρει στατιστικά σημαντική πτώση των συμπτωμάτων των κρανιο-γναθικών διαταραχών μετά τους 3 μήνες θεραπείας, σε σχέση με τον αρχικό κλινικό δείκτη και στις δύο ομάδες καθώς και στα δύο φύλα ασθενών
description: The objective of the present thesis was to investigate the contribution of homoeopathic therapeutic schemes in patients with cranio-mandibular disorders. This method included the collection of the study material, the formation of the specific sample, the application of suitable homoeopathic scheme, the protocol of re-examination and recording of clinical indexes, the selection of parameters for statistical evaluation and the statistical analysis. The study material were pa-tients of the clinics of Fixed Prosthodontics, School of Dentistry, of the Aristotle University of Thessaloniki, who have been examined for problems of craniomandibular disorders and had been treated with conservative therapeutic schemes during the period 1997-2003. The homoeopathic therapy was applied as complementary therapy. The groups that were formed and compared were two. Group A included patients with dominant the myofascial symptoms. Group B included dysfunctional patients with dominant symptoms of clicking and inter-nal derangement of temporomandibular joint with chronic headaches. The results show that the application of homoeopathic therapy has an effect on a considerable statistical decrease of symptoms of craniomandibular disorders afterwards the 3 months of therapy, in relation with the initial clinical indexes, in the two groups of patients

Βασίζεται σε ανέκδοτους Κώδικες που προέρχονται από το αρχείο της Ι. Μητροπόλεως και φυλάσσονται στη Δημοτική Βιβλιοθήκη της Κοζάνης και στα Γ.Α.Κ. ν. Κοζάνης. Η έννοια της μνηστείας ήταν ταυτόσημη με την έννοια του αρραβώνα, αν και ο αρραβώνας είχε και περιουσιακό περιεχόμενο. Η μνηστεία συνιστάτο σύμφωνα με το τυπικό που όριζε η εγκύκλιος του 1868. Οι μνηστοί δεν έπρεπε να υπάγονται στα κωλύματα που απαγόρευαν την τέλεση της μνηστείας και οι λόγοι λύσης της ήταν περιορισμένοι, σύμφωνα με αυτούς που προέβλεπε το επίσημο δίκαιο ή είχαν επικρατήσει στη νομολογία. Οι συνέπειες της λύσης της μνηστείας ήταν προσωπικές και περιουσιακές. Γαμήλιες παροχές, ήταν αυτές που δίνονταν με την προοπτική του γάμου. Κυριώτερη από την πλευρά της γυναίκας ήταν η προίκα. Αλλες παροχές ήταν το νάχτι, το τράχωμα, το αγριλίκι, η πρόγραμη δωρεά και η κρεβατοδωρεά. Σχετικό θέμα ήταν το προικοσύμφωνο στο οποίο καταγράφονταν η προίκα και άλλες γαμήλιες παροχές
description: The present research deals with engagement and marriage allowances in the case – law of the Ecclesiastical Courts of the Holy Metropolis of Servia and Kozani. The work is based on the unedited documents which are included in the ecclesiastical codes that derive from the records of the Holy Metropolis and are kept in the Municipal Library of Kozani and the General State Records of the prefecture of Kozani. According to the conclusions of the research, the concept of engagement is to a large extent synonumous to the concept of arrabon, which lies on the mutual promise of two persons that are going to get married. Arrabon, however, does also have property content which consists of the objects that were exchanged between the fiancιs during the engagement contract. Engagement was contracted according to either the ceremonial that was dictated by the 1868 encyclical, namely in front of the priestly principal and the witnesess, by drawing up the relative documents, or not formal. For the engagement to be valid, valious requirements were essential, such as certain age of the fiancιs, acquisienscence both theirs and their guardians, no blood relationship between them etc, exact Engagement used to be undone due to certain reasons, which were regulated by the formal law.ly like the obstacles that should not exist for the wedding to be contracted. Marriage allowances are the second issue that the research ewtensively deals with and mainly is dowry. Other allowances are nachti, agriliki, trachoma, bed donation and antenuptidl donation

description: We investigate the coronal magnetic energy and helicity budgets of ten solar ARs, around the times of large flares. In particular, we are interested in a possible relation of the derived quantities to the particular type of the flares that the AR produces, i.e., whether they are associated with a CME or they are confined. Using an optimization approach, we employ time series of 3D nonlinear force-free magnetic field models of ten ARs, covering a time span of several hours around the time of occurrence of large solar flares (GOES class M1.0 and larger). We subsequently compute the 3D magnetic vector potentials associated to the model 3D coronal magnetic field using a finite-volume method. This allows us to correspondingly compute the coronal magnetic energy and helicity budgets, as well as related (intensive) quantities such as the relative contribution of free magnetic energy, $E_{\mathrm{F}}/{E}$ (energy ratio), the fraction of non-potential (current-carrying) helicity, $|H_{\mathrm{J}}|/|{H_{V}}|$ (helicity ratio), and the normalized current-carrying helicity, $|H_{\mathrm{J}}|/{ϕ^{\prime}}^{2}$. The total energy and helicity budgets of flare-productive ARs (extensive parameters) cover a broad range of magnitudes, with no obvious relation to the eruptive potential of the individual ARs, i.e., whether or not a CME is produced in association with the flare. The intensive eruptivity proxies, $E_{\mathrm{F}}/{E}$ and $|H_{\mathrm{J}}|/|{H_{V}}|$, and $|H_{\mathrm{J}}|/{ϕ^{\prime}}^{2}$, however, seem to be distinctly different for ARs that produced CME-associated large flares compared to those which produced confined flares. For the majority of ARs in our sample, we are able to identify characteristic pre-flare magnitudes of the intensive quantities, clearly associated to subsequent CME-productivity.

description: BD+303639, the brightest planetary nebula at X-ray energies, was observed with Suzaku, an X-ray observatory launched on 2005 July 10. Using the X-ray Imaging Spectrometer, the K-lines from C VI, O VII, and O VIII were resolved for the first time, and C/O, N/O, and Ne/O abundance ratios determined. The C/O and Ne/O abundance ratios exceed the solar value by a factor of at least 30 and 5, respectively. These results indicate that the X-rays are emitted mainly by helium shell-burning products.

description: Основные потребители электроэнергии на карьерах это асинхронные двигатели и трансформаторы. При наличии реактивного сопротивления в цепи переменного тока под действием э.д.с. самоиндукции появляется реактивный ток, отстающий по фазе от напряжения на 90°. Реактивный ток необходим для создания магнитных полей в асинхронных двигателях и трансформаторах. Этот ток почти не зависит от нагрузки и определяет реактивную энергию, потребляемую двигателями и трансформаторами. Реактивный ток современных асинхронных двигателей составляет от 20 до 40% их полного тока, поэтому чем больше загружен двигатель, тем выше будет коэффициент мощности. Реактивный ток, потребляемый трансформаторами, также не зависит от нагрузки и составляет 4-6% от полного тока у крупных и 7-10% у трансформаторов малой и средней мощности.

description: We studied a sample of 274 radio and X-ray selected quasars (XQSOs) detected in the COSMOS and XXL-S radio surveys at 3 GHz and 2.1 GHz, respectively. This sample was identified by adopting a conservative threshold in X-ray luminosity, Lx [2-10\ keV] >= 10^44 erg/s, selecting only the most powerful quasars. Using available multiwavelength data, we examined various criteria for the selection of radio-loud (RL) and radio-quiet (RQ) XQSOs, finding that the number of RL/RQ XQSOs changes significantly depending on the chosen criterion. This discrepancy arises due to the different criteria tracing different physical processes and due to our sample being selected from flux-limited radio and X-ray surveys. Another approach to study the origin of radio emission in XQSOs is via their radio luminosity function (RLF). We constructed the XQSO 1.4 GHz radio luminosity functions (RLFs) in six redshift bins at 0.5 <= z <= 3.7. The lower-1.4 GHz luminosity end shows a higher normalization than expected only from AGN contribution in all studied redshift bins. The found "bump" is mostly dominated by emission due to star-forming (SF) processes within the XQSO host galaxies. As expected, AGN-related radio emission dominates at the higher-luminosity end of RLF. The evolution of XQSO RLF was studied via combination of analytic forms from the literature to constrain the lower-luminosity "bump" and the higher-luminosity AGN part of the RLF. We defined two 1.4 GHz luminosity thresholds, L_th,SF and L_th,AGN, below and above which more than 80% of sources contributing to the RLF are dominated by SF and AGN-related activity, respectively. These thresholds evolve with redshift, most likely due to the strong evolution of SFRs of the XQSO host galaxies.

Interchain coupling effects on photoinduced phase transitions between neutral and ionic phases in an extended Hubbard model with alternating potentials and an electron-lattice coupling

description: Dynamics of ionic-to-neutral and neutral-to-ionic phase transitions induced by intrachain charge-transfer photoexcitations are studied in a quasi-one-dimensional extended Hubbard model with alternating potentials and an electron-lattice coupling for mixed-stack charge-transfer complexes. For interchain couplings, we use electron-electron interactions previously estimated for TTF-CA (TTF=tetrathiafulvalene, CA=chloranil). Photoexcitation is introduced by a pulse of oscillating electric field. The time-dependent Hartree-Fock approximation is used for the electronic part, and the classical approximation for the lattice part. In the ionic-to-neutral transition, the transferred charge density is a strongly nonlinear function of the photoexcitation density, which is characterized by the presence of a threshold. With substantial interchain couplings comparable to those in TTF-CA, the interchain correlation is strong during the transition. Neutral domains in nearby chains simultaneously grow even if their nucleation is delayed by reducing the amplitude of the electric field. With weaker interchain couplings, the growing processes are in phase only when the amplitude of the electric field is large. Thus, the experimentally observed, coherent motion of a macroscopic neutral-ionic domain boundary is allowed to emerge by such substantial interchain couplings. In the neutral-to-ionic transition, by contrast, the transferred charge density is almost a linear function of the photoexcitation density. Interchain electron-electron interactions make the function slightly nonlinear, but the uncooperative situation is almost unchanged and consistent with the experimental findings.

description: Binding and unbinding of ligands to specific sites of a macromolecule are one of the most elementary molecular interactions inside the cell that embody the computational processes of biological regulations. The interaction between transcription factors and the operators of genes and that between ligands and binding sites of allosteric enzymes are typical examples of such molecular interactions. In order to obtain the general mathematical framework of biological regulations, we formulate these interactions as finite Markov processes and establish a computational theory of regulatory activities of macromolecules based mainly on graphical analysis of their state transition diagrams. The contribution is summarized as follows: (1) Stochastic interpretation of Michaelis-Menten equation is given. (2) Notion of \textit{probability flow} is introduced in relation to detailed balance. (3) A stochastic analogy of \textit{Wegscheider condition} is given in relation to loops in the state transition diagram. (4) A simple graphical method of computing the regulatory activity in terms of ligands' concentrations is obtained for Wegscheider cases.

description: The kinematics on spatially flat FLRW space-times is presented for the first time in co-moving local charts with physical coordinates, i. e. the cosmic time and Painlev\' e-type Cartesian space coordinates. It is shown that there exists a conserved momentum which determines the form of the covariant four-momentum on geodesics in terms of physical coordinates. Moreover, with the help of the conserved momentum one identifies the peculiar momentum separating the peculiar and recessional motions without ambiguities. It is shown that the energy and peculiar momentum satisfy the mass-shell condition of special relativity while the recessional momentum does not produce energy. In this framework, the measurements of the kinetic quantities along geodesic performed by different observers are analysed pointing out an energy loss of the massive particles similar to that giving the photon redshift. The examples of the kinematics on the de Sitter expanding universe and a new Milne-type space-time are extensively analysed.

Relationships between working memory and reading comprehension in beginning and intermediate readers
Creators: name: Molloy, Peter John
Publisher: name: University of British Columbia
Year: 2011

description: This study investigated the relationships between working memory and reading comprehension. Two non-linguistic (digit span and modified digit span) and two linguistic (word span and reading span) memory measures were used. These measures were comprised of 11 tests. From these tests, predictors of reading comprehension were sought. Two subtests from the Woodcock Reading Mastery Tests (W.R.M.T.) were used as a measure of reading comprehension. Age related differences between the 30 Grade 2 and 30 Grade 6 subjects were also investigated. Significant differences in the mean scores of the Grade 2 and 6's were found of all 5 of the non-linguistic tests but only on 1 of the linguistic tests. Familiarity with the lexicon used in the linguistic tasks may account for this. No significant interactions were found between grade measures. The modified digit span, word span and reading span tasks were found to be significant predictors of reading comprehension. The complex reading span measure had the highest level of significance of the three. This suggests that linguistic working memory task that had a capacity and processing component best predicts reading comprehension.

description: We demonstrate, both analytically and experimentally, free-space pin-like optical vortex beams (POVBs).Such angular-momentum-carrying beams feature tunable peak intensity and undergo robust anti-diffracting propagation, realized by judiciously modulating both the amplitude and the phase profile of a standard laser beam. Specifically, they are generated by superimposing a radially-symmetric power-law phase on a helical phase structure, which allows the inclusion of an orbital angular momentum term to the POVBs. During propagation in free-space, these POVBs initially exhibit autofocusing dynamics, and subsequently, their amplitude patterns morph into a high-order Bessel-like profile characterized by a hollow-core and an annular main-lobe with a constant or tunable width during propagation. In contrast with numerous previous endeavors on Bessel beams, our work represents the first demonstration of long-distance free-space generation of optical vortex 'pins', with their peak intensity evolution controlled by the impressed amplitude structure. Both the Poynting vectors and the optical radiation forces associated with these beams are also numerically analyzed, revealing novel properties that may be useful for a wide range of applications.

Use and Abuse of the Fisher Information Matrix in the Assessment of Gravitational-Wave Parameter-Estimation Prospects

description: The Fisher-matrix formalism is used routinely in the literature on gravitational-wave detection to characterize the parameter-estimation performance of gravitational-wave measurements, given parametrized models of the waveforms, and assuming detector noise of known colored Gaussian distribution. Unfortunately, the Fisher matrix can be a poor predictor of the amount of information obtained from typical observations, especially for waveforms with several parameters and relatively low expected signal-to-noise ratios (SNR), or for waveforms depending weakly on one or more parameters, when their priors are not taken into proper consideration. In this paper I discuss these pitfalls; show how they occur, even for relatively strong signals, with a commonly used template family for binary-inspiral waveforms; and describe practical recipes to recognize them and cope with them. Specifically, I answer the following questions: (i) What is the significance of (quasi-)singular Fisher matrices, and how must we deal with them? (ii) When is it necessary to take into account prior probability distributions for the source parameters? (iii) When is the signal-to-noise ratio high enough to believe the Fisher-matrix result? In addition, I provide general expressions for the higher-order, beyond--Fisher-matrix terms in the 1/SNR expansions for the expected parameter accuracies.

description: In the previous article (Found Phys. Lett. {\bf{16}} 325-341), we showed that a reciprocity of the Gauss sums is connected with the wave and particle complementary. In this article, we revise the previous investigation by considering a relation between the Gauss optics and the Gauss sum based upon the recent studies of the Weil representation for a finite group.

description: U.S. agricultural exports affected rural economies unevenly in the 1980's, benefiting 419 export-dependent counties the most during export trade upswings and hitting them the hardest during export trade downturns. Export-dependent counties are those in which 50 percent or more of total farm sales are generated by five major export-bound crops: corn, wheat, soybeans, cotton, and rice. Of those counties, economic boom-and-bust cycles were most severe in the 173 that also rely on farming for 20 percent or more of all labor and proprietor income. Economic expectations for export-dependent counties are brightening in the late 1980's because of farmers’ keener cost competitiveness, lighter farmer debt loads, export-oriented farm legislation, a depreciated dollar, and movement toward freer world trade.

description: This article presents a new numerical abstract domain for static analysis by abstract interpretation. It extends a former numerical abstract domain based on Difference-Bound Matrices and allows us to represent invariants of the form (+/-x+/-y<=c), where x and y are program variables and c is a real constant. We focus on giving an efficient representation based on Difference-Bound Matrices - O(n2) memory cost, where n is the number of variables - and graph-based algorithms for all common abstract operators - O(n3) time cost. This includes a normal form algorithm to test equivalence of representation and a widening operator to compute least fixpoint approximations.

description: Measurement of magnetic field strengths in a molecular cloud is essential for determining the criticality of magnetic support against gravitational collapse. In this paper, as part of the JCMT BISTRO survey, we suggest a new application of the Davis-Chandrasekhar-Fermi (DCF) method to estimate the distribution of magnetic field strengths in the OMC-1 region. We use observations of dust polarization emission at 450 $μ$m and 850 $μ$m, and C$^{18}$O (3-2) spectral line data obtained with the JCMT. We estimate the volume density, the velocity dispersion and the polarization angle dispersion in a box, 40$''$ $\times$ 40$''$ (5$\times$5 pixels), which moves over the OMC-1 region. By substituting three quantities in each box to the DCF method, we get magnetic field strengths over the OMC-1 region. We note that there are very large uncertainties in inferred field strengths, as discussed in detail in this paper. The field strengths vary from 0.8 to 26.4 mG and their mean value is about 6 mG. Additionally, we obtain maps of the mass-to-flux ratio in units of a critical value and the Alfv$\acute{e}$n mach number. The central parts of the BN-KL and South (S) clumps in the OMC-1 region are magnetically supercritical, so the magnetic field cannot support the clumps against gravitational collapse. However, the outer parts of the region are magnetically subcritical. The mean Alfv$\acute{e}$n mach number is about 0.4 over the region, which implies that the magnetic pressure exceeds the turbulent pressure in the OMC 1 region.

Metacognitive calibration in exercise : an examination using running and high-intensity functional movement exercise

description: In the present thesis, I examined exercise calibration using running and high-intensity functional movement exercise (HIFME). In doing so, I analysed and presented results from eight studies across Chapters 2, 3, 4, and 5. In Chapters 2 and 3, I explored the extent to which demographic factors (e.g. expertise, experience, age, and gender) are effective in informing us about running and HIFME calibration. Studies 1 and 2 demonstrated that such factors do exhibit associations with running calibration, though the relatively minor strength and inconsistency of these associations also indicate that we should not overestimate the factors’ contributions. Study 3 found a positive role of having a HIFME background in HIFME calibration, but other demographic factors did not exhibit associations with it. Overall, results from Chapters 2 and 3 highlighted the importance of considering demographic factors when assessing athlete calibration. However, they also highlighted the importance of understanding their limitations when doing so. In Chapter 4, I examined whether we can use self-reports of exercise metacognition and cognitive calibration to predict running and HIFME calibration. There was no significant association between any of these measures and exercise calibration in Studies 4, 5, and 6, suggesting that metacognition self-reports and calibration from other modalities are not reliable predictors of exercise calibration. In Chapter 5, I tested whether a minimal metacognitive intervention in the form of prediction guidance would lead to improved exercise calibration when participants received strategic, as opposed to impulsive, instructions. Findings from Studies 7 and 8 illustrated that strategic predictions facilitated prediction precision compared to impulsive predictions, though their effects on bias appeared to be less consistent and more dependent upon instructions. In Chapter 6, I discussed the general implications of the present thesis, and proposed ways in which future research can further explore the field of exercise calibration.

description: Excerpts from the report: The growth of grain imports by some developing countries slowed during the 1980's as their economies faltered and external debts mounted. The United States, the world's largest grain exporter, lost some of its grain markets as a result. U.S. policies further reduced U.S. exports as the United States lost market share in developing countries by holding export prices steady in the face of low world prices and high surpluses. With a higher exchange value of the dollar, U.S. agricultural exports became less competitive in world markets. This report shows how economic growth can lead developing countries to supplement local grain production with imports. Grain markets can grow if measures are undertaken to resolve the debt problems and promote economic development in developing countries. U.S. farmers could share in these growing markets if U.S. grain exports are priced competitively.
Phase textures induced by dc current pairbreaking in multilayer structures and two-gap superconductors

description: We predict current-induced formation of equilibrium phase textures for a multicomponent superconducting order parameter. Using the two-component Ginzburg-Landau and Usadel equations, we show that, for weakly coupled co-moving superconducting condensates, dc current I first causes breakdown of the phase locked state at $I>I_{c1}$ followed by the formation of intrinsic phase textures well below the depairing current $I_d$. These phase textures can manifest themselves in multilayer structures, atomic Bose condensate mixtures in optical lattices and two-gap superconductors, particularly MgB$_2$, where they can result in oscillating and resistive switching effects.

description: We examine the effects of horizontally layered heterogeneities on the spreading of two-phase gravity currents in a porous medium, with application to numerous environmental flows, most notably geological carbon sequestration. Geological heterogeneities, which are omnipresent within all reservoirs, affect the large-scale propagation of such flows through the action of small-scale capillary forces, yet the relationship between these small and large scales is poorly understood. Here, we derive a simple upscaled model for a gravity current under an impermeable cap rock, which we use to investigate the effect of a wide range of heterogeneities on the macroscopic flow. By parameterising in terms of different types of archetypal layering, we assess the sensitivity of the gravity current to the distribution and magnitude of these heterogeneities. Furthermore, since field measurements of heterogeneities are often sparse or incomplete, we quantify how uncertainty in such measurements is manifest as uncertainty in the macroscale flow predictions. Finally we apply our model to the Sleipner case study in the North Sea, positing how heterogeneities may have played a role in the observed migration of CO2.
Neutrino-Cooled Accretion Disks around Spinning Black Hole

description: We calculate the structure of accretion disks around Kerr black holes for accretion rates 0.001 - 10 M_sun/s. Such disks are plausible candidates for the central engine of gamma-ray bursts. Our disk model is fully relativistic and treats accurately microphysics of the accreting matter: neutrino emissivity, opacity, electron degeneracy, and nuclear composition. The neutrino-cooled disk forms above a critical accretion rate that depends on the black hole spin. The disk has the ``ignition'' radius r_ign where neutrino flux rises dramatically, cooling becomes efficient, and the proton-to-nucleon ratio Y_e drops. Other characteristic radii are r_alpha where most of alpha-particles are disintegrated, r_nu where the disk becomes neutrino-opaque, and r_trap where neutrinos get trapped and advected into the black hole. We find r_alpha, r_ign, r_nu, r_trap and show their dependence on the accretion rate. We discuss the qualitative picture of accretion and present sample numerical models of the disk structure. All neutrino-cooled disks regulate themselves to a characteristic state such that: (1) electrons are mildly degenerate, (2) Y_e ~ 0.1, and (3) neutrons dominate the pressure in the disk.
