description: This is the sixth paper presenting the results of the MUse RAdio Loud Emission line Snapshot survey (MURALES). We observed 37 radio sources from the 3C sample with z<0.3 and declination <20 degrees with the MUSE optical integral field spectrograph at the VLT. We here focus on the properties of the extended emission line regions (EELRs) that can be studied with unprecedented detail thanks to the depth of these observations. Line emission in the 10 FRIs is, in most cases, confined to within <4 kpc, while large-scale (>4 kpc) ionized gas is seen in all but two of the 26 FRIIs. It usually takes the form of elongated or filamentary structures, typically extending between 10 and 30 kpc, but also reaching distances of ~80 kpc. We find that 1) the large-scale ionized gas structures show a tendency to be oriented at large angles from the radio axis, and 2) the gas on a scale of a few kpc from the nucleus often shows ordered rotation with a kinematical axis forming a median angle of 65 degrees with the radio axis. We also discuss the velocity field and ionization properties of the EELRs. The observed emission line structures appear to be associated with gaseous "superdisks" formed after a gas rich merger. The different properties of the EELR can be explained with a combination of the source evolutionary state and the orientation of the "superdisk" with respect to the radio axis. The general alignment between the superdisks and radio axis might be produced by stable and coherent accretion maintained over long timescales.

description: We derive an induced Abelian Chern-Simons (CS) term in 2+1 dimensions, by dimensional reduction from the finite-temperature theory of a Dirac field with both vector and axial-vector couplings to two Abelian gauge fields, in 3+1 dimensions. In our construction, the CS term emerges for the lowest Matsubara mode of the vector Abelian field, by integrating the fermionic field, under the assumption that the axial vector field is in a "vacuum" configuration. This configuration is characterized by a single number, which in turn determines the coefficient of the induced CS term for the Abelian vector field.

Mean time to system failure

description: Reliability characteristics of repairable systems have been studied in the past in great detail by numerous researchers. Their findings are based mainly on the significant assumption that the repairs are carried out by one or more repair facilities, and the process of repair renews the functional behavior of the components or units in the system. In other words, the statistical properties of the components or units can be restored by carrying out the repair upon failure. This means that failed units may be trea ted “a s good a s new” after each repair. In many practical situations we observe that in the process of making a unit as good-as-new, considerable damage will be done to the operational ability of the repair facility, which may reflect upon the repair rates of the units in subsequent repairs. Intuitively, we expect that the average repair time of a unit to increase after each repair. This paper makes an attempt to incorporate these concepts in a two unit warm standby redundant system in which the efficiency, equivalently, repair capacity of the repair facility decreases upon each repair. Subsequently, the process of repair may not contribute significantly in improving the system reliability. In order to increase the system reliability and that the system might be available in the long run, an optimum replacement of the repair facility in terms of the mean time to system failure (MTSF) is suggested.

description: We study the relativistic 2D charge distributions in the case of a spin-$1$ target. These charge distributions are based on a phase-space approach allowing one to study their frame dependence, and hence to relate the familiar rest-frame picture with the light-front picture developed in the last two decades. Like in the spin-$1/2$ case, we show that relativistic kinematical effects associated with spin are responsible for the distortions of the charge distributions seen in a moving frame. Applying our results to the deuteron, we observe a mild frame dependence compared to the nucleon case.

description: The availability and profit values of the utensil industry are analyzed using the regenerative point graphical technique. The utensil industry contains three different units where two units can work with reduced capacity. It is considered that units C and D may be in a complete failed state through partial failure but unit B is in only complete failed state. When a unit is completely failed then the system is in failed state. An expert technician is available to repair the failed unit. Failure and repair times are independent of each other. The distribution of the failure time is general and repair time is exponential. Various parameters such as mean time to system failure, availability, busy period of the server, expected number of server visits and profit values are calculated with the help of tables.

description: Printed electronics offer ultra-low manufacturing costs and the potential for on-demand fabrication of flexible hardware. However, significant intrinsic constraints stemming from their large feature sizes and low integration density pose design challenges that hinder their practicality. In this work, we conduct a holistic exploration of printed neural network accelerators, starting from the analog-to-digital interface - a major area and power sink for sensor processing applications - and extending to networks of ternary neurons and their implementation. We propose bespoke ternary neural networks using approximate popcount and popcount-compare units, developed through a multi-phase evolutionary optimization approach and interfaced with sensors via customizable analog-to-binary converters. Our evaluation results show that the presented designs outperform the state of the art, achieving at least 6x improvement in area and 19x in power. To our knowledge, they represent the first open-source digital printed neural network classifiers capable of operating with existing printed energy harvesters.

multi-component and multi-phase queuing system

description: The article considers multi-component and multi-stage mathematical models of queuing systems (QS) with the distribution of the incoming flow simultaneously between the system components, which consist of a certain number of service channels and waiting places in the queue. The maintenance of requirements with a lack of time to stay in the service channel and waiting is considered, while the service process in the QS of each component consists of several stages with the corresponding duration, and the full-service period is equal to the sum of such time intervals. The number of components and their parameters correspond to the similar characteristics of the production divisions of the repair enterprise. The study of the effectiveness of the operation of the repair enterprise as a multi-component and multi-stage QS consists in determining the values of the initial parameters of the QS components, taking into account the restrictions imposed on them, in order to obtain the largest values of the probabilities of servicing the requirements of the QS components and the system as a whole. The model is implemented using Any Logic University Researcher, which allows you to combine the principles of system dynamics with the paradigms of agent and discrete-event modelling. The proposed approach to the modelling of maintenance and repair processes by production divisions of the enterprise as a multi-component and multi-phase QS allows to determine the effectiveness of the functioning of such a QS and to obtain arguments for increasing the efficiency of its operation.

description: Twisted magnons (TMs) carrying orbital angular momentum (OAM) have attracted much attention from the magnonic community. The fabrication of such novel magnon state however is still challenging. Here we present a simple method to generate TMs with arbitrary radial and azimuthal quantum numbers through the spin-to-orbital angular momentum conversion. The conversion rate from plane-wave magnons to twisted ones is shown to be insensitive to the quantum index. The spectrum of TMs in thin nanodisks is solved analytically, showing a good agreement with micromagnetic simulations. Moreover, we numerically study the propagation of TMs in magnetic nanodisk arrays and obtain the quantitative dependence of the decay length on quantum indexes. Our results are helpful for realizing TMs with large OAMs that are indispensable for future high-capacity magnonic communications and computings.

Dispersal of protoplanetary discs: How stellar properties and the local environment determine the pathway of evolution

description: We study the evolution and final dispersal of protoplanetary discs that evolve under the action of internal and external photoevaporation, and different degrees of viscous transport. We identify five distinct dispersal pathways, which are i) very long lived discs ($>20\,$Myr), ii) inside-out dispersal where internal photoevaporation dominates and opens inner holes, iii) outside-in dispersal where external photoevaporation dominates through disc truncation and two intermediate regimes characterised by lingering material in the inner disc with the outer disc dispersed predominantly by either internal or external photoevaporation. We determine how the lifetime, relative impact of internal and external winds and clearing pathway varies over a wide, plausible, parameter space of stellar/disc/radiation properties. There are a number of implications, for example in high UV environments because the outer disc lifetime is shorter than the time-scale for clearing the inner disc we do not expect transition discs to be common, which appears to be reflected in the location of transition disc populations towards the Orion Nebular Cluster. Irrespective of environment, we find that ongoing star formation is required to reproduce observed disc fractions as a function of stellar cluster age. This work demonstrates the importance of including both internal and external winds for understanding protoplanetary disc evolution.

description: An acceptance sampling plan is a sampling procedure with a set of rules for making decisions about a lot of products. The decision is based on the number of defectives in a sample. The sampling inspection plans which are developed for taking decision about a lot based on lifetime of the product are called reliability sampling plans. In this paper, we have developed Acceptance sampling plan (ASP) based on truncated life tests when the lifetime of a product follows the exponentiated generalized inverse Rayleigh distribution (EGIR). The minimum sample sizes needed to ensure the specified life percentile are obtained for a fixed value of the consumer™s confidence level. The operating characteristic values according to the different quality levels are obtained and the minimum ratios of the mean life to the specified life are calculated. The important tables based on the suggested acceptance sampling plan are calculated and illustrated.

description: An extensive catalog of spatially-resolved galaxy rotation curves and multi-band optical light profiles for 1752 observed spiral galaxies is assembled to explore the drivers of diversity in galaxy structural parameters, rotation curve shapes, and stellar mass profiles. Similar data were extracted from the NIHAO galaxy simulations to identify any differences between observations and simulations. Several parameters, including the inner slope "S" of a rotation curve (RC), were tested for diversity. Two distinct populations are found in observed and simulated galaxies; (i) blue, low mass spirals with stellar mass M* < 10^9.3 Msol and roughly constant "S", and (ii) redder, more massive and more diverse spirals with rapidly increasing "S". In all cases, the value of "S" seems equally contributed by the baryonic and non-baryonic (dark) matter. Diversity is shown to increase mildly with mass. Numerical simulations reproduce well most baryon-dominated galaxy parameter distributions, such as the inner stellar mass profile slope and baryonic scaling relations, but they struggle to match the full diversity of observed galaxy rotation curves (through "S") and most dark-matter-dominated parameters. To reproduce observations, the error broadening of the simulation's intrinsic spread of RC metrics would have to be tripled. The differences in various projections of observed and simulated scaling relations may reflect limitations of current sub-grid physics models to fully capture the complex nature of galaxies. For instance, AGNs are shown to have a significant effect on the shapes of simulated RCs. The inclusion of AGN feedback brings simulated and observed inner RC shapes into closer agreement.

description: That the exact quantum S-matrix of $\text{T}\bar{\text{T}}$-deformed field theories is known has interesting consequences for their perturbative renormalisation. Recent investigations into the interplay between renormalisation and integrable deformations have focused on those cases where the (undeformed) seed theories are integrable. In this paper, we study the perturbative renormalisation of non-integrable $\text{T}\bar{\text{T}}$-deformed field theories, focusing on a theory of scalars with a quartic interaction. We show that in this theory, the 4-point 1-loop S-matrix exhibits features similar to its integrable cousins. We also carry out a similar analysis for the case of an integrable quantum field theory comprising a pair of chiral bosons. Our discussion of this latter theory supplies the first explicit example of a perturbative field theory computation in the formalism due to Sen.

description: Consider managers evaluating their employees' performances. Should managers justify their subjective evaluations? Suppose a manager's evaluation is private information. Justifying her evaluation is costly but limits the principal's scope for distorting her evaluation of the employee. I show that the manager justifies her evaluation if and only if the employee's performance was poor. The justification assures the employee that the manager has not distorted the evaluation downwards. For good performance, however, the manager pays a constant high wage without justification. The empirical literature demonstrates that subjective evaluations are lenient and discriminate poorly between good performance levels. This pattern was attributed to biased managers. I show that these effects occur in optimal contracts without any biased behavior.

title: Akustik und ihre Bedeutung für das Theater des 19/20 Jahrhunderts am Beispiel des Bayreuther Festspielhauses und Max Reinhardts Großem Schauspielhaus

description: Im ersten Kapitel dieser Diplomarbeit wird der Stellenwert des Hörens in unserer Gesellschaft herausarbeitet. Wann beginnen wir zu hören? Welchen Status hat das Hören? Welchen psychologischen und philologischen Stellenwert hat das Hören? Der Theorieteil handelt von den raumakustischen Eigenschaften des Schalls, den wichtigsten Parametern einer erfolgreichen Akustik und akustischen Eigenschaften von Theatern. Der historische Teil der Arbeit bemüht sich die geschichtlichen und theoretischen Hintergründe, welche zu den Veränderungen im Theaterbau führten, herauszuarbeiten und deren Wirkung darzustellen. Viele innovative Ideen wurden zu dieser Zeit geboren, leider schafften es nur wenige Künstler ihre Vorstellungen in die Tat umzusetzen. Der nächste Teil dieser Diplomarbeit beschäftigt sich mit zwei der beeindruckensten Theaterbauten, die jemals in Betrieb genommen wurden, dem „Bayreuther Festspielhaus“ Richard Wagners in Bayreuth und dem „Großen Schauspielhaus“ von Max Reinhardt in Berlin. Diese beiden Gebäude konnten nur durch den unermüdlichen Einsatz und Ehrgeiz ihrer Erbauer verwirklicht werden. Diese beiden Künstler schafften es, ihre Vision eines Theaters ihrer Vorstellungen nach zu verwirklichen. Das Bayreuther Theater bricht als eines der ersten mit den gängigen Theater- oder Opernkonzeptionen und stellt einen Meilenstein der Theatergeschichte dar. Es ist auch das erste Theater, bei dem der griechische Festspielgedanke wieder aufgenommen wurde. Erneuerungen, wie zum Beispiel die Abdunkelung des Zuschauerraums, wurden in Bayreuth zum ersten Mal umgesetzt und konnten sich daraufhin in allen Theatern durchsetzen. Das Haus begeistert durch seine fantastische Akustik bis heute die Massen. Max Reinhardt versuchte ein Theater zu realisieren, in dem er große Massen an Menschen unterbringen konnte, um mit ihnen ein gemeinschaftliches Fest aus dem Geiste der griechischen Antike zu feiern, sie in einem riesigen Festsaal als Veranstaltungsraum in eine andere Welt entführen. Das Große Schauspielhaus von Max Reinhardt, welches von großartigen Ideen bestimmt wurde, scheiterte schlussendlich an den akustischen Problemen. Beide Theaterschaffenden waren von der griechischen Antike beeindruckt und versuchten die gemeinschaftlichen, demokratischen Ideen in ihren Theatern wieder aufleben zu lassen. Der letzte Teil dieser Diplomarbeit beschäftigt sich mit der Akustik von Theatern.
Investigating Sparsity in Recurrent Neural Networks

description: In the past few years, neural networks have evolved from simple Feedforward Neural Networks to more complex neural networks, such as Convolutional Neural Networks and Recurrent Neural Networks. Where CNNs are a perfect fit for tasks where the sequence is not important such as image recognition, RNNs are useful when order is important such as machine translation. An increasing number of layers in a neural network is one way to improve its performance, but it also increases its complexity making it much more time and power-consuming to train. One way to tackle this problem is to introduce sparsity in the architecture of the neural network. Pruning is one of the many methods to make a neural network architecture sparse by clipping out weights below a certain threshold while keeping the performance near to the original. Another way is to generate arbitrary structures using random graphs and embed them between an input and output layer of an Artificial Neural Network. Many researchers in past years have focused on pruning mainly CNNs, while hardly any research is done for the same in RNNs. The same also holds in creating sparse architectures for RNNs by generating and embedding arbitrary structures. Therefore, this thesis focuses on investigating the effects of the before-mentioned two techniques on the performance of RNNs. We first describe the pruning of RNNs, its impact on the performance of RNNs, and the number of training epochs required to regain accuracy after the pruning is performed. Next, we continue with the creation and training of Sparse Recurrent Neural Networks and identify the relation between the performance and the graph properties of its underlying arbitrary structure. We perform these experiments on RNN with Tanh nonlinearity (RNN-Tanh), RNN with ReLU nonlinearity (RNN-ReLU), GRU, and LSTM. Finally, we analyze and discuss the results achieved from both the experiments.
Tidally driven tectonic activity as a parameter in exoplanet habitability

description: Aims. On Earth, plate tectonics play an integral role in driving the long-term carbon cycle; however, on tidally locked rocky exoplanets alternative tectonic mechanisms driven by tidal stress and tidal heating could serve in an analogous way. Methods. We calculate tidal stress and tidal heating rates to model the likelihood of tectonic activity maintaining stable climates suitable for surface liquid water on tidally locked rocky exoplanets with radii ${R}_{p}$ $\le$ 1.23R$_\oplus$. Results. Applying the tidal models to our sample of 767 tidally locked rocky exoplanets reveals that $\sim$10% of exoplanets, including Proxima Cen b and GJ 1061 d from the circumstellar habitable zone (CHZ), pass the tidal stress subduction threshold for mobile lid tectonic activity and reside within the optimal tidal heating zone. This subset of exoplanets could sustain tidally induced temperate mobile lid tectonic activity comparable to plate tectonics on Earth, aiding in maintaining the presence of surface liquid water. Furthermore, $\sim$40% of exoplanets from our sample located in the CHZ would be unable to maintain the tectonic activity needed to stabilise the climate and are unlikely to retain surface liquid water. When broadening our modelling to establish the overlap between tidal stress, tidal heating, and the CHZ, to discover optimal regions to target for future observations, we determine that tidally driven tectonic activity conducive to the maintenance of surface liquid water occurs predominantly around M dwarfs, and identify intersections, where both mobile lid and optimal tidal heating could be sustained on eccentric (e>0.1) Earth-sized exoplanets (${R}_{p}$ = 1.0-1.23R$_\oplus$) orbiting in the CHZ of low-mass M dwarfs.

description: This paper focuses on estimating the product of two population means. Within this paper, we have introduced three distinct classes of estimators for product of two population means. These estimators take into account the known population mean of an auxiliary variable under the framework of stratified random sampling and the presence of non-response in the study variable. Basically, for case (I) we assume the non-response on the study variable and utilize the auxiliary information corresponding to the responding units of the study variable and in case (II), we utilize the complete dataset from the auxiliary variable while also accounting for non-response in the study variable. In case (III) we combined both the information of the auxiliary variable and assumed the non-response on the study variable. Expressions for bias and mean square error have been derived, extending up to the first-order derivative. We have also pinpointed some specific members of the proposed estimator. We have conducted a simulation study to evaluate the valuable insights into the performance of the suggested classes of estimators with the conventional estimator.

description: The cosmic ray ionization rate (CRIR) is a key parameter in understanding the physical and chemical processes in the interstellar medium. Cosmic rays are a significant source of energy in star formation regions, which impacts the physical and chemical processes which drive the formation of stars. Previous studies of the circum-molecular zone (CMZ) of the starburst galaxy NGC 253 have found evidence for a high CRIR value; $10^3-10^6$ times the average cosmic ray ionization rate within the Milky Way. This is a broad constraint and one goal of this study is to determine this value with much higher precision. We exploit ALMA observations towards the central molecular zone of NGC 253 to measure the CRIR. We first demonstrate that the abundance ratio of H$_3$O$^+$ and SO is strongly sensitive to the CRIR. We then combine chemical and radiative transfer models with nested sampling to infer the gas properties and CRIR of several star-forming regions in NGC 253 due to emission from their transitions. We find that each of the four regions modelled has a CRIR in the range $(1-80)\times10^{-14}$ s$^{-1}$ and that this result adequately fits the abundances of other species that are believed to be sensitive to cosmic rays including C$_2$H, HCO$^+$, HOC$^+$, and CO. From shock and PDR/XDR models, we further find that neither UV/X-ray driven nor shock dominated chemistry are a viable single alternative as none of these processes can adequately fit the abundances of all of these species.

The various Statistical properties of the proposed distribution like, reliability function, hazard rate function, reverse hazard rate function, moment generating function, quantile function, the coefficient of variation etc. are considered to understand its nature. Furthermore, we have used the method of maximum likelihood for estimation of the parameters of proposed distribution. Also, we obtain the Shannon’s entropy, stochastic ordering, Lorenz and Bonferroni curves. The performance of the proposed distribution is compared with competitive distributions using two real data sets.

description: The Developmental Journal for babies and young children with visual impairment (DJVI) is an early childhood intervention programme for babies and young children with severe visual impairment. It was developed by clinicians and clinical researchers from the Developmental Vision Programme at Great Ormond Street Hospital for Children NHS Foundation Trust and UCL Great Ormond Street Institute for Child Health (main authors Dr Alison Salt and Dr Naomi Dale). In 2005 it was commissioned by the English central government to be disseminated as the national early intervention framework for children with visual impairment and their families.

		The DJVI is a systematic framework tracking developmental and vision progress from birth to three years of age (or equivalent developmental age)

		The DJVI is designed to be used, in partnership with parents, by qualified clinicians and specialist professionals working in services providing support to babies and young children with visual impairment and their parents.

description: Metabolic disorders such as type 2 diabetes are increasing parallel to ageing and obesity and they have adverse effects on musculoskeletal health. This thesis demonstrated that poor metabolic health is associated with lower muscle and bone quality, concurrent exercise reduces bone loss due to diet-induced weight loss, and vitamin D supplementation enhances exercise-related improvements in body composition, in overweight and obese older adults. These findings suggest comprehensive musculoskeletal assessments are required in the clinical setting and exercise and dietary interventions are likely key for preventing and managing risk factors for falls and fractures in this growing population.

= Eruca vesicaria subsp. sativa (Mill.) Thell. in Hegi, Ill. Fl. Mitt.- Eur. 4: 201. 1918.
Notes. – Eruca vesicaria is one of the most variable species in the tribe Brassiceae due to its weediness and successful escape from cultivation as the salad crop arugula (English) or roquette (French) or as a source of industrial oil.
There is tremendous diversity in floral and leaf morphology, coupled with a greater variability in fruit length, width, seed size and number, and length of the apical segment “beak” relative to that of the proximal valvular segment.
All attempts in the past to accord species, subspecies, or varietal ranks to some of the variants led to further confusion, and the taxonomy of this complex is best served by the recognition of one species with two subspecies. The subsp. vesicaria has persistent calyx and is endemic to Spain, including the Balearic Islands, whereas subsp. sativa has readily deciduous calyx and is the cosmopolitan weed and cultivated crop.

description: This paper explores the interplay between the proliferation of wicked problems and the rapid advancement of digitization, particularly in the western hemisphere. It addresses the challenges posed to politics and public administration by these dual developments. Highlighting key areas of action tied to current socio-technical changes, the study finds that digitization increases social complexity, diversity, and uncertainty, often exacerbating goal conflicts. As societies transition to digital information societies, both the emergence of new wicked problems and the intensification of existing ones are anticipated. These developments present significant challenges for political and administrative entities, necessitating cultural and institutional innovations to enhance societal problem-solving capacities. The study underscores the need for adaptive strategies and innovative frameworks to navigate the evolving landscape shaped by digitization and its associated complexities
Nucleation and growth of iron pebbles explains the formation of iron-rich planets akin to Mercury

description: The pathway to forming the iron-rich planet Mercury remains mysterious. Mercury's core makes up 70% of the planetary mass, which implies a significant enrichment of iron relative to silicates, while its mantle is strongly depleted in oxidized iron. The high core mass fraction is traditionally ascribed to evaporative loss of silicates, e.g. following a giant impact, but the high abundance of moderately volatile elements in the mantle of Mercury is inconsistent with reaching temperatures much above 1,000 K during its formation. Here we explore the nucleation of solid particles from a gas of solar composition that cools down in the hot inner regions of the protoplanetary disc. The high surface tension of iron causes iron particles to nucleate homogeneously (i.e., not on a more refractory substrate) under very high supersaturation. The low nucleation rates lead to depositional growth of large iron pebbles on a sparse population of nucleated iron nano-particles. Silicates in the form of iron-free MgSiO$_3$ nucleate at similar temperatures but obtain smaller sizes due to the much higher number of nucleated particles. This results in a chemical separation of large iron particles from silicate particles with ten times lower Stokes numbers. We propose that such conditions lead to the formation of iron-rich planetesimals by the streaming instability. In this view, Mercury formed by accretion of iron-rich planetesimals with a sub-solar abundance of highly reduced silicate material. Our results imply that the iron-rich planets known to orbit the Sun and other stars are not required to have experienced mantle-stripping impacts. Instead their formation could be a direct consequence of temperature fluctuations in protoplanetary discs and chemical separation of distinct crystal species through the ensuing nucleation process.

description: This study delves into the computation and evaluation of the expected Fisher information matrix within the context of the Poisson-type I half logistic (PHL) distribution. Leveraging confidence intervals and their associated coverage probabilities, our investigation aimed to study the performance of information matrix by the maximum likelihood method in estimating parameters. Our results unveiled a consistent trend: as the sample size expanded, a reduction in the length of the confidence interval was observed, and the 95% asymptotic confidence interval’s coverage probability aligned within the expected nominal size. This serves as a testament to the accuracy and robustness of the information matrix’s performance within the PHL distribution framework. Also, tested using some real data set.
W49N MCN-a: a disk accreting massive protostar embedded in an early-phase hot molecular core

description: We present ALMA archival data for 219-235 GHz continuum and line observations toward the hot molecular core (HMC) W49N MCN-a (UCHII region J1) at a resolution of ~0."3. The dust continuum emission, showing an elongated structure of 1."40x0."95 (PA=43.5deg) perpendicular to the outflow seen in SiO and SO, represents a rotating flattened envelope, or torus, with a radius of 7,800au inclined at 47.5deg or larger. The emissions from CH3CN and 11 molecular lines exhibit a consistent velocity gradient as a result of rotation. The magnitude of each velocity gradient is different, reflecting that each line samples a specific radial region. This allows us to derive a rotation curve as Vrot prop R^0.44+-0.11 for 2,400au < R < 14,000au, giving the dynamical mass as Mdyn = 57.0+24.5-17.1 (R [au]/3, 000)^1.88 Msun. The envelope mass independently estimated from the dustemission is 910Msun (for Tdust =180K) for R<7,800au and 32Msun (for Tdust=300K) for R<1,700 au. The dynamical mass formula agrees well with these mass estimates within an uncertainty of a factor of three in the latter. The envelope is self-gravitating and is unstable to form spiral arms and fragments, allowing rapid accretion to the inner radii with a rate of order 10^-2 Msun yr^-1, although inward motion was not detected. The envelope may become a non self-gravitating Keplerian disk at R<(300-1,000) au. The formula is also consistent with the total mass ~10^4 Msun of the entire HMC 0.15 pc (31,000 au) in radius. Multiple transitions of CH3CN, HNCO and CH3OH provide the rotation temperatures, suggesting that the central source of MCN-a has an intrinsic bolometric luminosity of ~10^6 Lsun. These results have revealed the structure and kinematics of MCN-a at its intermediate radii. With no broad-line H30alpha emission detected, MCN-a may be in the earliest phase of massive star formation.
