description: The motion of a point mass in the J2 problem has been generalized to that of a rigid body in a J2 gravity field for new high-precision applications in the celestial mechanics and astrodynamics. Unlike the original J2 problem, the gravitational orbit-rotation coupling of the rigid body is considered in the generalized problem. The existence and properties of both the classical and non-classical relative equilibria of the rigid body are investigated in more details in the present paper based on our previous results. We nondimensionalize the system by the characteristic time and length to make the study more general. Through the study, it is found that the classical relative equilibria can always exist in the real physical situation. Numerical results suggest that the non-classical relative equilibria only can exist in the case of a negative J2, i.e., the central body is elongated; they cannot exist in the case of a positive J2 when the central body is oblate. In the case of a negative J2, the effect of the orbit-rotation coupling of the rigid body on the existence of the non-classical relative equilibria can be positive or negative, which depends on the values of J2 and the angular velocity. The bifurcation from the classical relative equilibria, at which the non-classical relative equilibria appear, has been shown with different parameters of the system. Our results here have given more details of the relative equilibria than our previous paper, in which the existence conditions of the relative equilibria are derived and primarily studied. Our results have also extended the previous results on the relative equilibria of a rigid body in a central gravity field by taking into account the oblateness of the central body.

description: Planetary nebulae (PNe) are powerful tracers of evolved stellar populations. Among the 3000 known PNe in the Galaxy, about 600 are located within the 520 square-degree area covered by the VVV survey. The VVV photometric catalogue provides an important new dataset for the study of PNe, with high-resolution imaging in five near-infrared bands. Aperture photometry of known PNe in the VVV area was retrieved from source catalogues. Care was taken to minimise any confusion with field stars. The colours of the PNe we are determined for H-Ks, J-H, Z-Y, and Y-J, and compared to stars and to other types of emission line objects. Cloudy photo-ionisation models were used to predict colours for typical PNe. We present near-infrared photometry for 353 known PNe. The best separation from other objects is obtained in the H-Ks vs. J-H diagram. We calculated the emission-line contribution to the in-band flux based on a model for NGC 6720: we find that this is highest in the Z and Y bands at over 50%, lower in the J band at 40%, and lowest in the H and Ks bands at 20%. A new view of PNe in the wavelength domain of the Z and Y bands is shown. Photo-ionisation models are used to explore the observed colours in these bands. The Y band is shown to be dominated by HeI 1.083 mu and HeII 1.012 mu, and colours involving this band are very sensitive to the temperature of the ionizing star. The VVV survey represents a unique dataset for studing crowded and obscured regions in the Galactic plane. The diagnostic diagrams presented here allow one to study the properties of known PNe and to uncover objects not previously classified.

description: To discuss the current evidence about radiolabeled-FAPI in patients affected by pancreatic cancer by underlying the advantages, disadvantages, and the future perspectives also in the theragnostic field. A literature search up until February 2023 was performed in PubMed, EBSCO, and EMBASE databases. Clinical reports, conference abstracts, editorials, and letters-to-the-editor were excluded. The results were presented according to the PRISMA guidelines. The quality of studies was evaluated by using the Critical Appraisal Skill Program checklist. From the initial 139 studies, 21 papers were selected for the final analysis. Ten papers were related to FAPI-uptake in health/benign/malignant pancreas, eight studies were focalized on the utility of radiolabeled-FAPI for the identification of premalignant and malignant pancreatic lesions and only three papers were related to the the theragnostic approach. Only two papers enrolled exclusively patients with pancreatic cancer undergoing FAPI-PET. In total, 55 patients underwent FAPI-PET for the identification of the suspicious mass/primary tumor (n = 43) and recurrent disease (n = 12). In both the studies, FAPI-PET detected more lesions than 2-[18F]FDG. Preliminary data about the FAPI-based theragnostic approach in patients with pancreatic cancer (n = 9 patients, totally) are now available. Radiolabeled-FAPI is a promising agent for the identification of pancreatic malignant lesions, but further prospective studies are still necessary.

description: Based on astrochemical theory, the complex molecular composition around high-mass YSOs should evolve from the outer envelope in toward the central hot region as a sequence of temperature dependent chemical pathways are activated in ices and in the gas-phase. The resulting complex molecules have been broadly classified into three generations dependent on the temperature (<25, >25, and >100 K) required for formation. We combine IRAM 30m and Submillimeter Array observations to explore the spatial distribution of organic molecules around the high-mass young stellar object NGC 7538 IRS9, whose weak complex molecule emission previously escaped detection, quantifying the emission and abundance profiles of key organic molecules as a function of distance from the central protostar. We find that emission from N-bearing organics and saturated O-bearing organics present large increases in emission around 8000 AU and R<3000 AU, while O-bearing molecules and hydrocarbons do not. The increase in flux from some complex molecules in the envelope, around 8000 AU or 25 K, is consistent with recent model predictions of an onset of complex ice chemistry at 20-30 K. The emission increase for some molecules at R<3000 AU suggests the presence of a weak hot core, where thermal ice evaporation and hot gas-phase chemistry drives the chemistry. Complex organics thus form at all radii and temperatures around this protostar, but the composition changes dramatically as the temperature increases, which is used to constrain the chemical generation(s) to which different classes of molecule belong.

Year: 2019

description: The Kentucky Geological Survey tested CO2-enhanced gas recovery in the Devonian shale in Johnson County, in response to a directive from the Kentucky General Assembly in 2007; the study site included a fracture-stimulated shale-gas well. To supplement a standard suite of open-hole logs acquired when the well was drilled, a well-logging program was designed to identify open perforations, construct a flow profile, and acquire pre-injection baseline data to characterize the Devonian Ohio Shale for a pressure falloff test. Tubing and packer were installed, with gel and brine filling the annulus between the tubing and packer to block flow-through perforations identified above the packer. From Sept. 6–10, 2012, 87 tons of CO2 was injected in three phases, with at least 12 hr between phases to allow for pressure decline. On the last day of injection, the pressure of the annulus between the casing and injection tubing approached the injection pressure, indicating CO2 had leaked out of the test zone. Therefore, the test was terminated before a planned injection of 300 tons of CO2 was completed. Following injection, the well was closed for 2 weeks to allow a “soak.” A meter run was constructed to monitor flowback, and during the flowback a second flow profile and post-injection production log were acquired. Analysis indicates the leak was likely the result of communication through induced fractures (from the original completion) from the Ohio Shale to the overlying Berea Sandstone. The Ohio Shale likely retained some of the CO2, thus confirming the potential to displace additional natural gas, but the small volume of CO2 and escape of an unknown amount of CO2 from the zone of interest severely constrained anything but a qualitative assessment.

description: The integration of optical technologies into once purely mechatronic systems enables innovative functions, but simultaneously increases the complexity of previous mechatronic system development. Therefore, a process has been elaborated to develop these so-called optomechatronic systems by Knöchelmann at the Institute of Product Development at Leibniz University Hanover, which is based on the V-Model of VDI 2206 and can be applied to various fields of application. For a target-oriented development in a specific product context and for systems with competing main requirements, detailing and adapting the process is recommended. High-resolution lighting systems are one of them, where requirements for high optical efficiency and image quality lead to a conflict of objectives. Focusing on the optics domain, Ley elaborated methods for the preliminary and detailed design of high-resolution lighting systems to address the aforementioned conflict of objectives. This contribution focuses on the integration of Ley’s design methods into Knöchelmann’s process model within the phases of system design and domain-specific design, allowing us to analyze the impact of the system design on the fulfillment of main requirements to achieve an optimal solution of the conflict of objectives. To illustrate this, the integrated process model is described using an example from automotive lighting technology.

description: We study a natural functional on the space of holomorphic sections of the Deligne–Hitchin moduli space of a compact Riemann surface, generalizing the energy of equivariant harmonic maps corresponding to twistor lines. We show that the energy is the residue of the pull-back along the section of a natural meromorphic connection on the hyperholomorphic line bundle recently constructed by Hitchin. As a byproduct, we show the existence of a hyper-Kähler potentials for new components of real holomorphic sections of twistor spaces of hyper-Kähler manifolds with rotating S1-action. Additionally, we prove that for a certain class of real holomorphic sections of the Deligne–Hitchin moduli space, the energy functional is basically given by the Willmore energy of corresponding equivariant conformal map to the 3-sphere. As an application we use the functional to distinguish new components of real holomorphic sections of the Deligne–Hitchin moduli space from the space of twistor lines. © 2020, The Author(s).

description: Givinostat (ITF2357), an oral, synthetic histone deacetylase inhibitor, significantly improved all histological muscle biopsy parameters in a Phase II study in boys with Duchenne muscular dystrophy (DMD). A population pharmacokinetic (PK) model, including seven clinical studies, was developed to explore the effect of covariates on givinostat PK. The final model was qualified to simulate pediatric dosing recommendations. A PK/pharmacodynamic (PD) model was developed to simulate the link between givinostat plasma concentration and platelet time course in 10–70-kg children following 6 months of givinostat 20–70 mg twice daily. A two-compartment model, with first-order input with lag and first-order elimination from the central compartment, described givinostat PK, demonstrating increasing apparent clearance with increasing body weight. The PK/PD model well-described platelet count time course. Weight-based dosing (arithmetic mean systemic exposure of 554–641 ng·h/mL) produced an average platelet count decrease from baseline of 45% with maximum decrease within 28 days. After 1 week and 6 months, ~1% and ~14–15% of patients, respectively, had a platelet count <75 × 109/L. Based on these data, givinostat dosing will be body weight adjusted and include monitoring of platelet counts to support efficacy and safety in a Phase III DMD study.

description: Long-acting injectable (LAI) formulations of second-generation antipsychotics (SGA) are a mainstay in the treatment of schizophrenia-spectrum patients, and their use improves adherence and reduces relapse risk. Personalizing LAI-based therapy involves tailoring the transition from oral to LAIs based on individual and drug-related pharmacokinetic peculiarities. We discuss pharmacokinetic considerations as a cornerstone of a smooth transition from oral to LAI SGAs based on works identified using an updated search in PubMed and Embase in February 2023. Establishing the extent of antipsychotic exposure during oral SGA-treatment from the patient’s SGA levels is often a more appropriate orientation method to choose the equivalent LAI dose than population-based data. Oral dose adjustment during LAI transition can also be guided by checking SGA levels before the LAI injection. LAI SGAs may dominate the maintenance treatment of schizophrenia-spectrum disorders with increased use for other severe mental illnesses such as bipolar disorder. Spurring this trend is the development of newer formulations with longer injection intervals and increased administration ease, but transitioning from oral SGA remains a challenge. By understanding the pharmacokinetics of LAI formulations and measuring SGA levels during oral therapy, one can personalize/optimize the switch from oral SGAs to LAI counterparts.

description: We consider N=(2,0) backgrounds of IIB supergravity on eight-manifolds M_8 with strict SU(4) structure. We give the explicit solution to the Killing spinor equations as a set of algebraic relations between irreducible su(4) modules of the fluxes and the torsion classes of M_8. One consequence of supersymmetry is that M_8 must be complex. We show that the conjecture of arxiv:1010.5789 concerning the correspondence between background supersymmetry equations in terms of generalized pure spinors and generalized calibrations for admissible static, magnetic D-branes, does not capture the full set of supersymmetry equations. We identify the missing constraints and express them in the form of a single pure-spinor equation which is well defined for generic SU(4)\times SU(4) backgrounds. This additional equation is given in terms of a certain analytic continuation of the generalized calibration form for codimension-2 static, magnetic D-branes.

description: In April of this year, a few hours before midnight , nine people loaded into a single pickup truck for an all-night journey from Murfreesboro, North Carolina to New York City. The days spent to, from, and in New York were quite an experience, involving meetings with union officials, national church groups, national foundations, and zipper manufacturing and equipment experts. The trip was one of the early steps in a struggle by a group of life-long residents of northeastern North Carolina to take local economic development into their own hands. These efforts began with the sudden closing of the Talon Zipper plant in Woodland, North Carolina, which at its peak had employed more than 450 people in a region where industrial jobs are few and far apart.

description: A sharp-interface model employing the extended finite element method is presented. It is designed to capture the prominent γ-γ′ phase transformation in nickel-based superalloys. The novel combination of crystal plasticity and sharp-interface theory outlines a good modeling alternative to approaches based on the Cahn–Hilliard equation. The transformation is driven by diffusion of solute γ′-forming elements in the γ-phase. Boundary conditions for the diffusion problem are computed by the stress-modified Gibbs–Thomson equation. The normal mass balance of solute atoms at the interface yields the normal interface velocity, which is integrated in time by a level set procedure. In order to capture the influence of dislocation glide and climb on interface motion, a crystal plasticity model is assumed to describe the constitutive behaviour of the γ-phase. Cuboidal equilibrium shapes and Ostwald ripening can be reproduced. According to the model, in low γ′ volume-fraction alloys with separated γ′-precipitates, interface movement does not have a significant effect on tensile creep behaviour at various lattice orientations.

description: Propotional paths as summed up by the Goldscheider Rule (GR) -- stating that given a constant strain rate, the evolution of the stress maintains the ratios of its components -- is a characteristics of elasto-plastic motion in granular media. Barodesy, a constitutive relation proposed recently by Kolymbas, is a model that, with GR as input, successfully accounts for data from soil mechanical experiments. Granular solid hydrodynamics (GSH), a theory derived from general principles of physics and two assumptions about the basic behavior of granular media, is constructed to qualitatively account for a wide range of observation -- from elastic waves over elasto-plastic motion to rapid dense flow. In this paper, showing the close resemblance of results from Barodesy and GSH, we further validate GSH and provide an understanding for GR.

Three essays on business analytics in accounting
Creators: name: Wang, Wenru
Publisher: name: No Publisher Supplied
Year: 2022

description: This dissertation focuses on applying different business analytics techniques in accounting and audit. The dissertation intends to provide insights for academia and practitioners, especially those supporting the public sector. The first essay adopts the idea of continuous audit and monitoring and creates a use case on government medication procurement. The proposed methodology aims to help internal auditors identify questionable procurement records for further investigation. By introducing exogenous data resources, the methodology also presents savings opportunities. The second essay is to measure the COVID-19 pandemic from the accounting perspective. This study applies the system dynamics theory and proposes a dynamic model to understand the ongoing pandemic using business measurements and analytical technologies. This study also estimates the feedback effects of pandemic-related policy measures. The deliverables of this study establish a dynamic view to understand the current pandemic and provide the government with a simulation tool to visually evaluate the impacts of government interventions at different levels.The third essay is motivated by the call for the evolving responsibilities of the audit profession. This study creates a dynamic model to explore the costs and benefits of continuous audit technology adoption in a public sector procurement process. The proposed model is based on the balanced scorecard and the theory of system dynamics to illustrate why the government should consider adopting technology in operations to help with performance measurement.

A partir de la campaña de infección en la red llamada “Blackshade”, llevada a cabo en 2012, el gobierno sirio consiguió información de  la  misma forma en  que  fue  obtenida la  de Taymour: un software espía que daba libre acceso a contraseñas e información contenidas en la red.

description: Recently, nonlocality and Bell inequalities have been used to investigate quantum phase transitions (QPTs) in low-dimensional quantum systems. Nonlocality can be detected by the Bell-CHSH function (BCF). In this work, we extend the study of BCF to the QPTs in matrix product systems (MPSs). In this kind of QPTs, the ground-state energy keeps analytical in the vicinity of the QPT points, and is usually called the MPS-QPTs. For several typical models, our results show that BCF can signal the MPS-QPTs very well. In addition, we find BCF can capture signal of QPTs in unentangled states and classical states, for which other measures of quantum correlation (quantum entanglement and quantum discord) fail. Furthermore, we find that in these MPSs, there exists some kind of quantum correlation which cannot be characterized by entanglement, or by nonlocality.

The early time observations of SN 2012aw clearly detect minima in the light-curve of V, R and I bands near 37 days after explosion and this we suggest to be an observational evidence for emergence of recombination phase. The mid-plateau MV magnitude (-16.67 $\pm$ 0.04) lies in between the bright (~ -18) and subluminous (~ -15) IIP SNe. The mass of nickel is 0.06$\pm$0.01 M_sun. The SYNOW modelling of spectra indicate that the value and evolution of photospheric velocity is similar to SN 2004et, but about ~600 km/s higher than that of SNe 1999em and 1999gi at comparable epochs. This trend is more apparent in the line velocities of H alpha and H beta. A comparison of ejecta velocity properties with that of existing radiation-hydrodynamical simulations indicate that the energy of explosion lies in the range 1-2x10^51 ergs; a further comparison of nebular phase [Oi] doublet luminosity with SNe 2004et and 1987A indicate that the mass of progenitor star is about 14-15 M_sun. The presence of high-velocity absorption features in the mid-to-late plateau and possibly in early phase spectra show signs of interaction between ejecta and the circumstellar matter; being consistent with its early-time detection at X-ray and radio wavebands.

description: New faunistic data on the occurrence of true bugs in the location of Kalwaria Pacławska- Pacław [FV29] (the Eastern Beskid Mts., SE Poland) are presented. The observations were carried out in 2016–2017 in three different habitats with the participation of oaks - exposed (without undergrowth) luminous oak forest (about 394 m asl), fresh upland forest (about 407 m asl) and a solitary oak growing on the edge of the forest (about 392 m asl). The following methods were used to catch insects in these habitats: Barber soil traps, IBL-5 barrier traps and Moericke's yellow pan traps. As a result of the research works, 38 true bugs species (including 32 new) from 12 families were found. The largest number of true bug species was found in the solitaire oak growing on the forest's edge using Moericke's yellow pan traps – 12 species. The largest number of species using all types of traps was shown in the luminous oak forest, and most species, when all types of biotopes are considered, were shown using Moericke's yellow pan traps –  respectively, 23 and 18 species. The most interesting species identified during the research are Mermitelocerus schmidtii (Fieber, 1836), Temnostethus gracilis Horváth, 1907, Loricula exilis (Fallén, 1807) and Campylosteira verna (Fallén, 1826).  As a consequence of our research, the number of known true bug species in Kalwaria Pacławska increased to 65, and the entire FV29 UTM square to 89 species.

description: The present note deals with a nonstandard systems of differential equations describing a two-species phase segregation. This system naturally arises in the asymptotic analysis carried out recently by the same authors, as the diffusion coefficient in the equation governing the evolution of the order parameter tends to zero. In particular, an existence result has been proved for the limit system in a very general framework. On the contrary, uniqueness was shown by assuming a constant mobility coefficient. Here, we generalize this result and prove a continuous dependence property in the case that the mobility coefficient suitably depends on the chemical potential.

description: Background: An average of 3 out of every 1000 children are born with a hearing loss. Both hearing screening and intervention services have a significant positive impact on these children. The current study focused on screening services. There were two objectives. 1. Systematic Review: To identify and examine the reported factors and outcomes of hospital-based newborn hearing screening (NHS) programs. Factors and outcomes include screening protocol, type of equipment, coverage rates, referral rates, loss to follow up (LTF) rates and Birth Screening Performance Index (BSPI) 2. Guatemala NHS Program: To examine outcomes from Guatemala’s program relative to the systematic review results. Methods: Eligible studies published in English up to February 2019 were identified through searches of PubMed (NCBI), the Cochrane Library, ASHA Wire and relevant article reference lists. The data were screened using pre-defined inclusion and exclusion criteria to generate a list of eligible articles. Data extracted included age at screening, screening rate, referral rate, LTF rate, and number of newborns identified with permanent congenital hearing loss. Systematic Review Results: This review identifies factors that affect BSPI, coverage rates, referral rates and loss to follow up rates in hospital-based universal NHS programs. 45 articles were included for data extraction and analysis.

Year: 1979

description: Over the past twenty years, we have witnessed the emergence of a multitude of information systems, both in the public and private sectors. These systems have provided a more effective means, in terms of cost and time, to process large amounts of raw data. Their use has, in many instances, allowed for unrestricted data communication, eliminated redundancy, facilitated updating procedures, provided a method for data standardization and classification, and improved data analysis. The following article will examine a specific type of information system, namely a land information system, which is institutionalized at a specific administrative level of government, the state. These systems have been primarily utilized by those public agencies and private groups involved in the land planning and management process.

description: En 1873 salió Obras de Virgilio traducidas en versos castellanos, con una introducción y notas por Miguel Antonio Caro, tomo I. La dedicatoria del autor pone: “A la Academia Española, en prenda de agradecimiento y testimonio de adhesión. Tales sentimientos reflejan la relación entre el autor y la corporación madrileña. ¿De qué naturaleza? Se trata de una confluencia de intereses en el campo de las letras, vale decir, en la República de las letras. Los estudios virgilianos del señor Caro principiaron con su traslado del libro cuarto de la Eneida. Obrita presentada a la consideración de Eugenio de Ochoa (1815-72), de la Academia Española y autor de una versión en prosa (1869), de modo que era la vigente entonces. Leída la del bogotano, le comunicó su juicio, en mayo de 1870: “La mejor prueba que puedo dar a V. del verdadero aprecio con que miro las varias publicaciones suyas, es (...) proponer a V. (...), para individuo correspondiente de nuestra Academia Española en esa capital”. Fundación de la Academia Colombiana

description: Due to the complex mechanisms, the ultrasonic (US) wire bonding process is usually optimized in the way of varying the processing parameters including normal force, US power, and processing time. In this study, a new way by creating different surface textures on substrates was used to alter the bonding process and improvements of the bonding process were detected. Three different surface textures including deposited strips, straight ditches at different angles, and elliptic ditches were designed and created on glass substrates. The results showed that the elliptic ditches hardly influence the bonding process while the deposited strips and straight ditches significantly alter the bonding process. The deposited strips help break the oxide scale and facilitate the transportation of oxides to the outside of contact. With the straight ditches, the oxide removal efficiency was significantly enhanced. Especially when the driving current exceeded 0.45 A, long chips from the ditches were clearly observed during the bonding process. The chips were aluminum and aluminum oxide which were continuously cut from the wire, accumulated in the ditches, pressed and squeezed to the outside of the contact. With a different angle of the straight ditches, the shape of the bonding footprint can be changed correspondingly. Compared to the bonding on smooth surfaces, the bonding strength on substrates with deposited strips and straight ditches was a few times higher and had a smaller deviation. The bonding process window was significantly enlarged.

description: We investigate the interaction between a single atom and optical pulses in a coherent state with a controlled temporal envelope. In a comparison between a rising exponential and a square envelope, we show that the rising exponential envelope leads to a higher excitation probability for fixed low average photon numbers, in accordance to a time-reversed Weisskopf-Wigner model. We characterize the atomic transition dynamics for a wide range of the average photon numbers, and are able to saturate the optical transition of a single atom with ~50 photons in a pulse by a strong focusing technique. For photon numbers of ~1000 in a 15ns long pulse, we clearly observe Rabi oscillations.

El legado de Cuentos de Tokio, sesenta años después

description: Cuentos de  Tokio quizá sea  una  de  las  películas japonesas más  elogiadas por  los  críticos y  la audiencia mundial. Dirigida por Yasujirō Ozu, la película se estrenó en 1953, con una historia que, al parecer, es bastante simple: una pareja de casados viaja a Tokio para visitar a sus hijos, a quienes hace muchos años no ven. Sin embargo, la simplicidad de la narrativa contrasta con la densidad y complejidad de  los  temas que,  poco  a  poco, se  van  desenvolviendo para  poner en  evidencia la melancolía que predominó en la sociedad japonesa de la segunda posguerra
