description: We develop a general power counting scheme for the infrared limit of Landau gauge SU(N) Yang-Mills theory in arbitrary dimensions. Employing a skeleton expansion, we find that the infrared behavior is qualitatively independent of the spacetime dimension d. In the cases d=2, 3 and 4 even the quantitative results for the infrared exponents of the vertices differ only slightly. Therefore, corresponding lattice simulations provide interesting qualitative information for the physical case. We furthermore find that the loop integrals depend only weakly on the numerical values of the IR exponents.

description: Shanghai Dreams (Qinghong青红), directed by Wang Xiaoshuai (王小帅,1966- ), is the first work created by a famed Chinese sixth-generation auteur to deal with the subject of construction of the “third line of defense” by focusing on the aftermath of this movement. This paper puts the movie vis-a-vis the historical experience of China’s change from Maoist socialism to Dengist pragmatism, and suggests that it is the conflicts between the authoritative Dengism and the residual Maoism that constitute the core of this political melodrama. The choice of the object of love and preference by the three protagonists has its allegorical significance related to the competition for the future and the re-structuration of class hierarchy in the post-revolutionary society. An episode of a failed Bildungsroman or the coming-of-age narrative, the film nevertheless fails to give a poignant political diagnosis of the social-political problems exemplified in the story which appears as a tragedy.

description: Extending independently the Balitsky-Kovchegov (BK) equation to running coupling or to fluctuation effects due to Pomeron loops is known to lead in both cases to qualitative changes of the traveling-wave asymptotic solutions. In this paper we study the extension of the forward BK equation, including both running coupling and fluctuations effects, using the method developed for the fixed coupling case. We derive the exact asymptotic behavior of the probabilistic distribution of the saturation scale.

description: Existing researches about Chinese non-profit organizations' rationalization tended to lay particular stress on specific or "net" effects explained by a particular theoretical perspective, thereby rarely considered from the interrelation of various theoretical perspectives or from the configuration perspective and hereby summarizing the effects of different mechanisms in specific environments as well as their connections or alternatives. As an important methodology and tool which emphasizes combined action of multiple mechanisms, qualitative comparative analysis (QCA) provides a possibility for the study. Through the meticulous sorting and analysis of 14 cases from three areas in Z Province of China by utilizing qualitative comparative analysis, this paper finds two important new findings. First, in terms of facilitating the rationalization of non-profit organizations, the mechanisms of competition, resource, and system are not simply replaceable by each other but complementary in many cases; especially, accordingly configurations are formed between system-related mechanism and resource mechanism and between system-related mechanism and competition mechanism, which constructs the critical path of Chinese non-profit organizations' rationalization. Second, the relationship among the different sub-mechanisms of the same theory is relatively complicated.

Environmental Protection Law

description: Is the Environmental Police (EP) the solution to close the remaining gaps preventing an effective Environmental Protection Law (EPL) implementation? By analyzing the different concepts behind and needs for a Chinese EP, this question is answered. The Environmental Protection Bureau (EPB) has the task of establishing, implementing, and enforcing the environmental law. But due to the fragmented structure of environmental governance in China, the limited power of the EPBs local branches, e.g. when other laws overlap with the EPL, low level of public participation, and lacking capacity and personnel of the EPBs, they are vulnerable and have no effective means for law enforcement. An EP could improve this by being a legal police force. Different approaches have been implemented on a local basis, e.g. the Beijing or Jiangsu EP, but they still lack a legal basis and power. Although the 2014 EPL tackled many issues, some implementation problems remain: The Chinese EP needs a superior legal status as well as the implementation of an EP is not further described. It is likely that the already complex police structure further impedes inter-department-cooperation. Thus, it was proposed to unite all environment-related police in the EP. Meanwhile the question will be raised, which circumstance is making large scale environmental pollution possible and which role environmental ethics play when discussing the concept of EPs.
Bailouts and Bankruptcy law in China: A Confusion of Law and Policy

description: It is not uncommon for large companies in China, especially SOEs, to be bailed out with government funds or bank loans. This article explores the bailouts of non-financial companies in the country with empirical and theoretical analysis. It finds that the government, especially the local governments are keen to bail out large companies in order to prevent social instability. Also, bailouts in China are still erratic and unprincipled. When bailouts are carried out under the bankruptcy law, legal principles are frequently undermined to the detriment of the creditors. This article argues that bailouts and governmental intervention in general must be constrained with legal principles so that inefficient companies can be closed down and resource can be allocated more efficiently.

description: This paper contextualizes China’s contemporary global cultural footprints by examining the recent development of its cultural diplomacy. It started with discussing the limitations of applying ‘soft power’ as the mainstream analytical tool: its lack of historical perspective and engagement of the domestic dimension, as well as the incompatibility with the very purpose of cultural diplomacy with its binary view of cultures and values. Then an alternative and more sophisticated framework of analysis building on cultural hegemony, Orientalism and nationalism is proposed to look beyond and beneath the soft power narrative to reveal a three-dimensional picture against the historical, international and domestic contexts. The dynamics among all the forces at work in this terrain are also critically analyzed to illuminate the complex nature of this uneven global cultural terrain of struggle and the unique challenges faced by China’s cultural diplomacy

description: No abstracts are to be cited without prior reference to the author.Studies of fishing gear performance and fish behaviour in nets have shown that captureefficiency is very variable. Ta investigate thecatching performance of the GOV trawl, data werecollected on 11 surveys. It was thought that catch would depend mainly on fishing ground,depth, year, swept volume, towing speed, water temperature and light intensity. The paperpresents summary data on catches and the measured gear and environmental parameters,showing considerable variability. Catch size appeared to be re lated to fishing area, water depthand year. Preliminary analysis suggested that it would be technically difficult to relate catch sizeto the other measured parameters.. The observed variability in towing speed and hence gearperformance appeared high and there is need to improve towing speed control during thesurveys. Some evidence was found of gear inefficiency at higher towing speeds.

description: Recent extinction studies of the Pipe Nebula (d=130 pc) reveal many cores spanning a range in mass from 0.2 to 20.4 Msun. These dense cores were identified via their high extinction and comprise a starless population in a very early stage of development. Here we present a survey of NH3 (1,1), NH3 (2,2), CCS (2_1,1_0), and HC5N (9,8) emission toward 46 of these cores. An atlas of the 2MASS extinction maps is also presented. In total, we detect 63% of the cores in NH3 (1,1) 22% in NH3 (2,2), 28% in CCS, and 9% in HC5N emission. We find the cores are associated with dense gas (~10^4 cm-3) with 9.5 < T_k < 17 K. Compared to C18O, we find the NH3 linewidths are systematically narrower, implying that the NH3 is tracing the dense component of the gas and that these cores are relatively quiescent. We find no correlation between core linewidth and size. The derived properties of the Pipe cores are similar to cores within other low-mass star-forming regions: the only differences are that the Pipe cores have weaker NH3 emision and most show no current star formation as evidenced by the lack of embedded infrared sources. Such weak NH3 emission could arise due to low column densities and abundances or reduced excitation due to relatively low core volume densities. Either alternative implies that the cores are relatively young. Thus, the Pipe cores represent an excellent sample of dense cores in which to study the initial conditions for star formation and the earliest stages of core formation and evolution.

description: In recent years, medical science – and not only – has shifted towards a more personalized approach, relying on an individual’s profile rather than generalizations. This trend is also reflected in the present master's thesis, which leverages machine learning techniques to automate the detection of blood vessels in ultrasound images.

For this purpose, two datasets of medical ultrasound images were used. The first dataset focuses on the brachial plexus and includes 1,052 two-dimensional images from 101 patients, stored in JPEG format, with corresponding masks in JSON format. The second dataset focuses on the carotid artery and the internal jugular vein, containing 2,439 two-dimensional images from 15 participants, stored as NumPy arrays. In the first dataset, veins, arteries, muscles, and nerves were labeled (with this study focusing exclusively on veins and arteries), while the second dataset contained labels only for veins and arteries.

Initially, data preprocessing was performed, including the conversion of images to NPY format and the merging of the two datasets. Additional processing steps followed, which are described in detail in the chapters of this thesis. Subsequently, two deep learning models were selected for comparison: U-Net and SegNet, both of which are deep learning architectures commonly used for image segmentation. Their algorithms were developed and trained using the available data to achieve optimal blood vessel detection.

Finally, evaluation metrics were applied, highlighting not only the quality of the results but also their generalization capability. This further underscores the contribution of this study to the automation of medical diagnostics, making the process faster, easier, and more cost-effective.

description: We performed the timing and spectral studies of a Z source GX 17+2 observed from Astrosat LAXPC instrument. Cross-Correlation function (CCF) was performed using soft (3-5 keV) and hard (16-40 keV) X -ray bands across the hardness intensity diagram and found correlated/anti-correlated hard and soft lags which seems to be a common feature in these sources. We performed spectral analysis for few of these observations and found no consistent variation in the spectral parameters during the lags, however 10-40% change was noticed in diskbb and power-law components in few of observations. For the first time, we report the detection of HBOs around $\sim$25 Hz and $\sim$ 33 Hz along with their harmonics using AstroSat LAXPC data. On comparison with spectral results of HB and other branches, we found that inner disk front is close to the last stable orbit and as such no systematic variations are observed. We suggest that the detected lags are readjustment time scales of corona close to the NS and constrained its height to be around few tens to hundreds of km. The detected lags and no significant variation of inner disk front across the HID strongly indicate that structural variation in corona is the most possible cause of Z track in HID.

description: We consider Feshbach scattering of fermions in a one-dimensional optical lattice. By formulating the scattering theory in the crystal momentum basis, one can exploit the lattice symmetry and factorize the scattering problem in terms of center-of-mass and relative momentum in the reduced Brillouin zone scheme. Within a single band approximation, we can tune the position of a Feshbach resonance with the center-of-mass momentum due to the non-parabolic form of the energy band.

description: The future ATLAS ITk strip tracker will consist of 17,000 silicon strip detector modules mounted on support structures called cores. Cores are assembled from a number of components, among others carbon fibre facings, honeycomb structure and carbon foam surrounding titanium tubes used for cooling, using a two-component epoxy (Hysol 9396) loaded with boron nitride for good thermal conductivity. The adhesive constitutes about 20 % of a core's weight. During operation, the detector is cooled down to -40 $^\circ$C using bi-phase carbon dioxide and flushed with dry gas to prevent condensation. The effect of this temperature change has been simulated to study the impact of Coefficient of Thermal Expansion (CTE) mismatches between different materials and investigate resulting deformations and misalignment. In addition to the shrinking of an adhesive during cooling, which can be estimated well using its known CTE, flushing the detector volume with dry gas removes the moisture contained in the adhesive, leading to an additional shrinking. In order to estimate the impact of shrinking during drying, the Coefficient of Moisture Expansion (CME) of Hysol samples with different contents of boron nitride as well as their overall moisture absorption were measured and their extent compared to the contraction associated with cooling.

The weakest conjecture, A, became known as the ``$3^d$-conjecture''. It is well-known that the three conjectures hold in dimensions d \leq 3. We show that in dimension 4 only conjectures A and B are valid, while conjecture C fails. Furthermore, we show that both conjectures B and C fail in all dimensions d \geq 5.

description: Observations of massive stars in young open clusters (< ~8 Myr) have shown that a majority of them are in binary systems, most of which will interact during their life. Populations of massive stars older than ~20 Myr allow us to probe the outcome of such interactions after many systems have experienced mass and angular momentum transfer. Using multi-epoch integral-field spectroscopy, we investigate the multiplicity properties of the massive-star population in NGC 330 (~40 Myr) in the Small Magellanic Cloud to search for imprints of stellar evolution on the multiplicity properties. From six epochs of VLT/MUSE observations supported by adaptive optics we extract spectra and measure radial velocities for stars brighter than F814W = 19. We identify single-lined spectroscopic binaries through significant RV variability as well as double-lined spectroscopic binaries, and quantify the observational biases for binary detection. The observed spectroscopic binary fraction is 13.2+/-2.0 %. Considering period and mass ratio ranges from log(P)=0.15-3.5, and q = 0.1-1.0, and a representative set of orbital parameter distributions, we find a bias-corrected close binary fraction of 34 +8 -7 %. This seems to decline for the fainter stars, which indicates either that the close binary fraction drops in the B-type domain, or that the period distribution becomes more heavily weighted towards longer orbital periods. Both fractions vary strongly in different regions of the color-magnitude diagram which probably reveals the imprint of the binary history of different groups of stars. We provide the first homogeneous RV study of a large sample of B-type stars at a low metallicity. The overall bias-corrected close binary fraction of B stars in NGC 330 is lower than the one reported for younger Galactic and LMC clusters. More data are needed to establish whether this result from an age or a metallicty effect.

description: Brands in the mental lexicon: brand names evoked by phonetic similarities in word association databases


Brands came into the focus of research in the last three decades. Recently the center of attention shifted from brands as identifying signs to brands as psychological constructs implying that brand names, as essential parts of brands, can be considered to be entities residing in the mental lexicon. Present paper assumes that brand names, as part of the lexicon appear in
word association databases and that phonetic similarities play a role in evoking brand names as associations. The research analyzes word association databases from the 1980s and 2000s collected in Hungarian in Hungary and in Zakarpattia Oblast and investigates brand names appearing in those databases. In the research, brand names evoked by means of phonetic similarities are collected and categorized. Results show that the underlying processes evoking brand names by means of phonetic similarities are similar to those observed by Gósy–Kovács
(2001) and Lengyel (2012). Some features of associations like association chains or wrong associations are, however, easier to discover when they are connected to brand names. The final section of the paper presents managerial implications by showing how the results can be used to improve a brand’s marketing communication.

description: A projective scheme $X$ is called `quadratic' if $X$ is scheme-theoretically cut out by homogeneous equations of degree 2. Furthermore, we say $X$ satisfies `property $\textbf{N}_{2,p}$' if it is quadratic and the quadratic ideal has only linear syzygies up to first $p$-th steps. In the present paper, we compare the linear syzygies of the inner projections with those of $X$ and obtain a theorem on `embedded linear syzygies' as one of our main results. This is the natural projection-analogue of `restricting linear syzygies' in the linear section case, \cite{EGHP1}. As an immediate corollary, we show that the inner projections of $X$ satisfy property $\textbf{N}_{2,p-1}$ for any reduced scheme $X$ with property $\textbf{N}_{2,p}$. Moreover, we also obtain the neccessary lower bound $(\codim X)\cdot p -\frac{p(p-1)}{2}$, which is sharp, on the number of quadrics vanishing on $X$ in order to satisfy $\textbf{N}_{2,p}$ and show that the arithmetic depths of inner projections are equal to that of the quadratic scheme $X$. These results admit an interesting `syzygetic' rigidity theorem on property $\textbf{N}_{2,p}$ which leads the classifications of extremal and next to extremal cases. For these results we develope the elimination mapping cone theorem for infinitely generated graded modules and improve the partial elimination ideal theory initiated by M. Green. This new method allows us to treat a wider class of projective schemes which can not be covered by the Koszul cohomology techniques, because these are not projectively normal in general.

description: Infrequent communications between the extremes of Eurasia existed prior to the Mongols, but they were often through intermediaries. Despite of its destructive force, the rise of the Mongol Empire allowed merchants and missionaries to transverse Eurasia. The conquests in many ways changed and enriched Eastern knowledge of Europe. This paper will firstly introduce what was known of Europe from a small quantity of Chinese and Mongol source material, including records mentioning the ‘Franks’ in the Early Yuan Period. The Mongol view and knowledge of Christian Europe in the thirteenth century will be discussed. The paper will be ended by examining Rabban Sawma’s mission to the Latin West.

description: The electrical functionality of an array of semiconductor nanocrystals depends critically on the free carriers that may arise from impurity or surface doping. Herein, we used InAs nanocrystals thin films as a model system to address the relative contributions of these doping mechanisms by comparative analysis of as-synthesized and Cu-doped nanocrystal based field-effect transistor (FET) characteristics. By applying FET simulation methods used in conventional semiconductor FETs, we elucidate surface and impurity-doping contributions to the overall performance of InAs NCs based FETs. As-synthesized InAs nanocrystal-based FETs show n-type characteristics assigned to the contribution of surface electrons accumulation layer that can be considered as an actual electron donating doping level with specific doping density and is energetically located just below the conduction band. The Cu-doped InAs NCs FETs show enhanced n-type conduction as expected from the Cu impurities location as an interstitial n-dopant in InAs nanocrystals. The simulated curves reveal the additional contribution from electrons within an impurity sub-band close to the conduction band onset of the InAs NCs. The work therefore demonstrates the utility of the bulk FET simulation methodology also to NC-based FETs. It provides guidelines for control of doping of nanocrystal arrays separately from surface contributions and impurity doping in colloidal semiconductor NCs towards their future utilization as building blocks in bottom-up prepared optoelectronic devices.

description: We construct uncertainty intervals for weak Poisson signals in the presence of background. We consider the case where a primary experiment yields a realization of the signal plus background, and a second experiment yields a realization of the background. The data acquisitions times for the background-only experiment,T_bg, and the primary experiment,T, are selected so that their ratio varies from 1 to 25. The expected number of background counts in the primary experiment varies from 0.2 to 2. We construct 90 and 95 percent confidence intervals based on a propagation-of-errors method as well as two implementations of a Neyman procedure where acceptance regions are constructed based on a likelihood-ratio criterion that automatically determines whether the resulting confidence interval is one-sided or two-sided. The first Neyman procedure (due to Feldman and Cousins) neglects uncertainty in the background. In the other Neyman procedure, we account for uncertainty in the background with a parametric bootstrap method. We also construct minimum length Bayesian credibility intervals. For each method, we test for the presence of a signal based on the value of the lower endpoint of the uncertainty interval. When T_bg/T is 5 or more and the expected background is 2 or less, the Feldman Cousins method outperforms the other methods considered.

description: No abstracts are to be cited without prior reference to the author.Fish form schools, layer or patches in which the individual fish's behaviour is not independent ofits neighbours movements. On the other hand, at low densities fish may have the freedom to actas single individuals independently of what other fish are doing. Potentially, if these contrastsoccur in nature, they may give rise to behavioural differences of fish in front of the trawl at highand low d~nsities with successive effects on catchability arid bottom trawl rndices of stockabundance.We explore in this paper the hypothesis that the density of fish has a significant effect oncatchability of the survey trawl. Data from Norwegian and Canadian video observationrecordedduring trawling are studied, and related to bag trawl experiments which measuredescapementundemeath the survey trawls in both regions.

description: The production of low mass e+e- pairs for m_{e+e-} < 300 MeV/c^2 and 1 < p_T <5 GeV/c is measured in p+p and Au+Au collisions at sqrt(s_NN)=200 GeV. Enhanced yield above hadronic sources is observed. Treating the excess as internal conversions, the invariant yield of direct photons is deduced. In central Au+Au collisions, the excess of direct photon yield over p+p is exponential in transverse momentum, with inverse slope T = 221 +/- 19 (stat) +/- 19 (syst) MeV. Hydrodynamical models with initial temperatures ranging from 300--600 MeV at times of ~ 0.6 - 0.15 fm/c after the collision are in qualitative agreement with the data. Lattice QCD predicts a phase transition to quark gluon plasma at ~ 170 MeV.

description: We report the fluorescence emission which is driven by femtosecond laser pulses with a repetition rate of 100 MHz and a center wavelength of 1040 nm in a nitrogen gas jet. The experiment is performed in a femtosecond enhancement cavity coupled with high repetition rate laser for the first time to the best of our knowledge. In contrast to previous observation at low repetition rate with a nitrogen gas jet, where the 391 nm radiation was observed but the 337 nm emission was missing, the 337 nm emission is 3 times stronger than the 391 nm emission in our experiment. By examining the dependence of the radiation intensity on the flow rate of the nitrogen gas and the polarization of the pump pulse, the formation mechanism of the N2(C3Πu) triplet excited state, i.e., the upper state of the 337 nm emission, is investigated. We attribute the main excitation process to the inelastic collision excitation process, and exclude the possibility of the dissociative recombination as the dominate pathway. The role of the steady state plasma that is generated under our experimental conditions is also discussed.

description: We present the results of long-term photometric monitoring of two active galactic nuclei, 2MASX J08535955+7700543 (z $\sim$ 0.106) and VII Zw 244 (z $\sim$ 0.131), being investigated by the reverberation mapping method in medium-band filters. To estimate the size of the broad line region, we have analyzed the light curves with the JAVELIN code. The emission line widths have been measured using the spectroscopic data obtained at the 6-m BTA telescope of SAO RAS. We give our estimates of the supermassive black hole masses $\lg (M/M_{\odot})$, $7.398_{-0.171}^{+0.153}$, and $7.049_{-0.075}^{+0.068}$, respectively

Postmodernist Elements in Mao’s Thoughts

Postmodernism

description: While “Marxian,” Mao’s thought came from a wide variety of sources, notably from his cultural roots and from his life-long study of classical Chinese philosophy, which in many aspects registers a striking affinity with the postmodernist movement of the West in the late 20th century. Mao’s Chinese Marxism can be interpreted as a break-away from traditional Marxism, a political-economic-philosophical metanarrative, which is culturally Eurocentric and epistemologically logocentric—formulated along the line of rationalistic thinking that can be traced back through the Enlightenment all the way to Plato’s idealism. Postmodernism “abandons absolute standards, universal categories, and grand theories in favor of local, contextualized, and pragmatic conceptual strategies” (Seidman, 1994: 207). This article has no intention to declare Mao as a complete postmodernist, but the obvious would have to be pointed out: i.e., Mao’s notion of integrating Marxism into the specific situation of China is clearly in favor of what Seidman has called “local, contextualized, and pragmatic conceptual strategies,” which explains why the Chinese revolution, essentially an agrarian revolution, led by him had turned out to be a success story. This article will be centering around two basic themes: one is to trace Mao’s thought to ancient Chinese philosophy, which differs radically from its Western counterpart but contains ideas and thoughts strongly echoed by postmodernist thinkers in the West; the other is to look closely at some of the key concepts in Mao’s philosophy in connection with postmodernism, along with his strong anti-metaphysical stance, to explore how it was possible for him to create conceptual leeway for launching his own philosophical, and political, break-through.

description: The onset of structural arrest and glass formation in a concentrated suspension of silica nanoparticles in a water-lutidine binary mixture near its consolute point is studied by exploiting the near-critical fluid degrees of freedom to control the strength of an attraction between particles and multispeckle x-ray photon correlation spectroscopy to determine the particles' collective dynamics. This model system undergoes a glass transition both on cooling and on heating, and the intermediate liquid realizes unusual logarithmic relaxations. How vitrification occurs for the two different glass transitions is characterized in detail and comparisons are drawn to recent theoretical predictions for glass formation in systems with attractive interactions.

description: Avalanche photodiodes fabricated from AlInAsSb grown as a digital alloy exhibit low excess noise. In this paper, we investigate the band structure-related mechanisms that influence impact ionization. Band-structures calculated using an empirical tight-binding method and Monte Carlo simulations reveal that the mini-gaps in the conduction band do not inhibit electron impact ionization. Good agreement between the full band Monte Carlo simulations and measured noise characteristics is demonstrated.

China’s rise
‘Party-Led State’

description: China experienced a successful development in an era when the western world is in apparent declining. Has China's rise made its approach to the development of a new model for the emerging world? China model in modern concept is normally recognised as an alternative to mainstream western model of development. However, in 1970s, many scholars attempted to examine China model as an alternative to Soviet model. China model described by different scholars in different historical period has different meaning and it seems challenging to find a universal definition of China model. This paper will show the challenges faced by ‘Democratic-Capitalist Model’, and examine the terminology ‘China model of development’ through summarising and analysing the major success elements of China model from comparative perspective including findings from other scholars. Afterwards, this paper shows all the success elements of China model is based on the fundation of ‘Party-Led State’. The ‘Party-Led State’ might be able to provide stability during modernisation, capable to push the economy to develop and reform, and also able to integrate different ideas and interests through consultative democracy. In addition, it will further discuss the existence and feasibility of China Model and its preconditions for emerging world to adopt. At last, it will point out that China model is a continuous progressing model rather than static prescription like ‘Washington Consensus’.

description: No abstracts are to be cited without prior reference to the author.The probability of cod (Gadus morhua) and ling (Molva molva) to encounter a fleet of fourgillnets (110 m) set within a fixed survey area of 600x600 m2 and soaked for aperiod of 12 h(1800-0600 hrs) is calculated on the basis of in situ observations of fish movement andrandom simulated start positions and setting directions of a fleet of gillnets. The movementsof cod and ling, which were tagged by allowing them to voluntarily swallow bait-wrappedtransmitters dose to the sea bed, were studied by means of a stationary positioning system.The expected number of encounters per fish for the fleet of gillnets varied between 0.127 and0.626 for cod and 0.077 and 0.614 for ling with a fish density of three fish per 0.1 (n.mile)2.
X-ray spectroscopy in the microcalorimeter era III: line formation under Case A, Case B, Case C, and Case D in H- and He-like iron for a photoionized cloud

description: Future microcalorimeter X-ray observations will resolve spectral features in unmatched detail. Understanding the line formation processes in the X-rays deserves much attention. The purpose of this paper is to discuss such processes in the presence of a photoionizing source. Line formation processes in one and two-electron species are broadly categorized into four cases. Case A occurs when the Lyman line optical depths are very small and photoexcitation does not occur. Line photons escape the cloud without any scattering. Case B occurs when the Lyman-line optical depths are large enough for photons to undergo multiple scatterings. Case C occurs when a broadband continuum source strikes an optically thin cloud. The Lyman lines are enhanced by induced radiative excitation of the atoms/ions by continuum photons, also known as continuum pumping. A fourth less-studied scenario, where the Case B spectrum is enhanced by continuum pumping, is called Case D. Here, we establish the mathematical foundation of Cases A, B, C, and D in an irradiated cloud with Cloudy. We also show the total X-ray emission spectrum for all four cases within the energy range 0.1 - 10 keV at the resolving power of XRISM around 6 keV. Additionally, we show that a combined effect of electron scattering and partial blockage of continuum pumping reduces the resonance line intensities. Such reduction increases with column density and can serve as an important tool to measure the column density/optical depth of the cloud.

description: Alice and Bob want to share a secret key and to communicate an independent message, both of which they desire to be kept secret from an eavesdropper Eve. We study this problem of secret communication and secret key generation when two resources are available -- correlated sources at Alice, Bob, and Eve, and a noisy broadcast channel from Alice to Bob and Eve which is independent of the sources. We are interested in characterizing the fundamental trade-off between the rates of the secret message and secret key. We present an achievable solution and prove its optimality for the parallel channels and sources case when each sub-channel and source component satisfies a degradation order (either in favor of the legitimate receiver or the eavesdropper). This includes the case of jointly Gaussian sources and an additive Gaussian channel, for which the secrecy region is evaluated.
