Este estudo analisa, sob a abordagem institucional, as implicacoes da implantacao de um Centro de Servicos Compartilhados (CSC) nas funcoes da Contabilidade Gerencial. Para tal, foi realizada uma pesquisa de natureza descritiva com abordagem qualitativa, a partir de um estudo de caso em empresa situada na regiao Sul do Brasil, constituida sob a forma de um CSC. Sob a lente da Teoria Institucional, consubstanciada no modelo proposto por Burns e Scapens (2000), foi analisada a institucionalizacao de regras e rotinas na Contabilidade Gerencial da empresa. Os resultados da pesquisa mostram que a implantacao do CSC teve implicacoes diretas e indiretas nas funcoes da Contabilidade Gerencial, visto que foi necessario alterar varias de suas funcoes, atividades, divisionalizacoes, inclusive profissionais, portanto, uma reestruturacao ampla e profunda em todo o setor. Quanto as dicotomias de mudancas ocorridas com a implantacao do CSC, foram observadas mais mudancas formais do que informais, evolucionarias do que revolucionarias e progressivas do que regressivas nas funcoes da Contabilidade Gerencial. Conclui-se com base na analise triangulada dos dados coletados, que a implantacao do CSC na empresa pesquisada teve implicacoes significativas na estrutura organizacional e na natureza das funcoes da Contabilidade Gerencial, as quais resultaram na institucionalizacao de novas regras e rotinas nos moldes preconizados por Burns e Scapens (2000). Os resultados do estudo contribuem para o desenvolvimento de novos papeis na Contabilidade Gerencial, sob o argumento que o modelo de CSC gerou novas regras e rotinas em toda a corporacao, com implicacoes diretas e indiretas nos papeis gerenciais institucionalizados.
A Decoupling Control Method for Converting DIDO Sequence Admittance Model of Grid-Tied Converter System Into SISO

This article proposes a decoupling control method to eliminate frequency coupling in three-phase grid-tied system. Firstly, the admittance model of three-phase LCL-type three-phase grid-tied converter (GTC) considering DC-bus voltage control (DVC) loop and phase-locked loop (PLL) is established in dq-domain frame, and the influence of asymmetrical DVC and PLL control structure on frequency coupling oscillation is analyzed. Then decoupling factors are added to the DVC loop and current control (CC) loop to achieve that the off-diagonal elements of the sequence admittance matrix of the GTC are 0, which means the frequency coupling in the GTC is eliminated. Therefore, the GTC system can be regarded as a single input single output (SISO) system, and the stability can be analyzed by the classic Nyquist criterion in the sequence-domain frame. Compared with the double input double output (DIDO) system, the resulted SISO system convenient for calculating the stability margin of the system and guiding parameter design. In addition, the SISO system is easier to be analyzed on the oscillation and resonance mechanism, and the analysis results can be used to optimize the design of the converter controller, grid planning and operation. Finally, simulation and experiment verify the feasibility and effectiveness of the proposed decoupling control method.
Risk Factors for Depression in Pregnancy: Scoping Review

Antenatal depression has become a common and serious problem that can affect the health of both mother and baby. This study aims to review the latest obstetric scientific evidence on the risk factors for depression in pregnancy. This research is a Scoping review using the Arkshey & O'Malley Framework and the PRISMA-ScR Checklist. The literature search used 3 databases, namely Pubmed, Science Direct, and Wiley Online Library. The keywords used were pregnant women, risk factors, and pregnancy depression. The inclusion criteria were original articles; published in 2018 to 2022, in English, open access and full text, and a focus on risk factors for pregnancy depression. Article quality assessment uses the Joanna Briggs Institute (JBI) Checklist. 13 articles were quantitative studies conducted in hospitals and clinics, and came from 8 different countries. Mapping themes from the results of the article analysis are the prevalence of depression in pregnancy, risk factors based demographics including age, education level, marital status and occupation, risk factors based on obstetric characteristics including the number of pregnancies, history of abortion, unwanted pregnancies and diseases in pregnancy, as well as risk factors based on psychosocial including husband support, family, domestic violence, and harmful habits. Information on recognizing risk factors for depression in pregnancy is important for health workers to detect depression on time and implement relevant psychosocial interventions to reduce the incidence of depression during pregnancy
Analysis of propagation properties of terahertz hollow-optical fiber by using time-domain spectroscopy and application for THz wave remote spectroscopy

Terahertz pulse propagation in hollow optical fibers is investigated by using terahertz time-domain spectroscopy. From evaluation of transmission loss spectra of hollow optical fiber, it is found that TM11 mode propagates as well as TE11 mode that is the lowest order mode in terahertz metal-hollow fiber. Short-time Fourier transform is also applied for investigation of mode properties and as a result, it is confirmed that the interference peaks in the loss spectra are due to mode mixing in hollow optical fibers. Finally we performed a terahertz wave remote spectroscopy using the hollow optical fiber and acquired a clear transmission spectrum of the theophylline.
Generating pre-fractals to approach real IFS-attractors with a fixed Hausdorff dimension

In this paper, we explain how to generate adequate pre-fractals in order to properly approximate attractors of iterated function systems on the real line within a priori known Hausdorff dimension. To deal with, we have applied the classical Moran's Theorem, so we have been focused on non-overlapping strict self-similar sets. This involves a quite significant hypothesis: the so-called open set condition. The main theoretical result contributed in this paper becomes quite interesting from a computational point of view, since in such a context, there is always a maximum level (of the natural fractal structure we apply in this work) that may be achieved.
A hybrid computational approach for option pricing

In this paper, we propose a novel numerical approach for option pricing with the combination of the MC (Monte Carlo) simulation and the PDE (partial differential equation) approach. Our motivation originates from the fact that within a finite life time of an option contract, the underlying price as well as the range of volatility are expected to vary within a relatively small region centered around the current value of the underlying and the volatility and hence there is no need to compute option prices for the underlying and the volatility values beyond this region. Thus, our hybrid approach takes the advantage of both the MC simulation and PDE approach to form an approach that takes the MC simulation as a special case with the region being extremely small and the PDE approach as another special case with the region being extremely large. Through numerical experiments, we demonstrate that such a hybrid approach enhances computational efficiency, while maintaining the same level of accuracy when either the MC simulation or the PDE approach is used alone for the option prices computed within a suitably chosen interested region.
The embedded contact homology of toric contact manifolds

Embedded contact homology (ECH) is an invariant of a contact three-manifold. In Part I of this thesis, we provide a combinatorial description of the ECH chain complex of certain ``toric'' contact manifolds. This is an extension of the combinatorial description appearing in Hutchings-Sullivan. ECH capacities are invariants of a symplectic four-manifold with boundary, which give obstructions to symplectically embedding one symplectic four-manifold with boundary into another. In Part II of this thesis, we compute the ECH capacities of a large family of symplectic four-manifolds with boundary, called ``concave toric domains''. Examples include the (nondisjoint) union of two ellipsoids in $\R^4$. We use these calculations to find sharp obstructions to certain symplectic embeddings involving concave toric domains. This is a joint work with D. Cristofaro-Gardiner, D. Frenkel, M. Hutchings and V. G. B. Ramos.

A statistical nuclear estimator is developed for evaluation of the corresponding angular distributions taking into account the weights of registered quanta.
Optimasi Formula Sediaan Krim Ekstrak Stroberi (Fragaria x ananassa) sebagai Krim Anti Penuaan

Penuaan adalah suatu proses biologis kompleks sebagai hasil dari penuaan intrinsik (dari dalam tubuh seperti genetik) dan penuaan ekstrinsik (dari lingkungan). Faktor yang paling berpengaruh pada penuaan adalah radikal bebas karena dapat menyebabkan stres oksidatif yang berperan penting dalam proses penuaan. Penggunaan antioksidan dari buah-buahan salah satunya stroberi, menjadi suatu faktor penting untuk melawan penuaan akibat radikal bebas. Antosianin di dalam stroberi memiliki efek antioksidan paling tinggi untuk melawan radikal bebas. Antioksidan tersebut digunakan dalam produk kosmetik untuk memaksimalkan perawatan terhadap penuaan. Penelitian ini bertujuan untuk mengoptimasi formula sediaan krim ekstrak stroberi dengan membandingkan penggunaan jenis emulgator nonionik dan anionik. Ekstrak stroberi didapatkan dengan mengektraksi stroberi menggunakan pelarut metanol, aquades, dan asam format. Ekstrak diformulasikan ke dalam krim yang dibagi menjadi dua formula yaitu formula A yang menggunakan emulgator nonionik (tween 80 dan span 80) dan formula B yang menggunakan emulgator anionik (sodium oleate dan trietanolamin). Penentuan stabilitas dan formula yang optimum didapatkan dari evaluasi sediaan krim yang meliputi uji organoleptis, uji homogenitas fisik, uji pH, uji daya sebar, uji daya lekat, dan uji stabilitas suhu.

Kata kunci: Ekstrak stroberi, Jenis emulgator, Stabilitas sediaan krim.
Impact of urban canopy models and external parameters on the modelled urban energy balance in a tropical city

To date, existing urban land surface models (ULSMs) have been mostly evaluated and optimized for mid‐ and high‐latitude cities. For the first time, we provide a comparative evaluation of four ULSMs for a tropical residential neighbourhood in Singapore using directly measured energy balance components. The simulations are performed offline, for an 11 month period, using the bulk scheme TERRA_URB and three models of intermediate complexity (CLM, SURFEX and SUEWS). In addition, information from three different parameter lists are used to quantify the impact (interaction) of (between) external parameter settings and model formulations on the modelled urban energy balance components. Encouragingly, overall results indicate good model performance for most energy balance components and align well with previous findings for midlatitude regions, suggesting the transferability of these models to (sub)tropical regions. Similar to results from midlatitude regions, the outgoing long‐wave radiation and latent heat flux remain the most problematic fluxes. In addition, the various combinations of models and different parameter values suggest that error statistics tend to be dominated more by the choice of the latter than the choice of model. Finally, our intercomparison framework enabled the attribution of common deficiencies in the different model approaches found previously in midlatitude regions: the simple representation of water intercepted by impervious surfaces leading to a positive bias in the latent heat flux directly after a precipitation event; and the positive bias in modelled outgoing long‐wave radiation that is partly due to neglecting the radiative interactions of water vapour between the surface and the tower sensor. These findings suggest that future developments in urban climate research should continue the integration of more physically based processes in urban canopy models, ensure the consistency between the observed and modelled atmospheric properties and focus on the correct representation of urban morphology, water storage and thermal and radiative characteristics.
Spherical aberration correction of adaptive lenses

Deformable mirrors are the standard adaptive optical elements for aberration correction in confocal microscopy. Their usage leads to increased contrast and resolution. However, these improvements are achieved at the cost of bulky optical setups. Since spherical aberrations are the dominating aberrations in confocal microscopy, it is not required to employ all degrees of freedom commonly offered by deformable mirrors. In this contribution, we present an alternative approach for aberration correction in confocal microscopy based on a novel adaptive lens with two degrees of freedom. These lenses enable both axial scanning and aberration correction, keeping the setup simple and compact. Using digital holography, we characterize the tuning range of the focal length and the spherical aberration correction ability of the adaptive lens. The operation at fixed trajectories in terms of focal length and spherical aberrations is demonstrated and investigated in terms of reproducibility. First results indicate that such adaptive lenses are a promising approach towards high-resolution, high-speed three-dimensional microscopy.
Growth and nonlinear saturation of electromagnetic ion cyclotron waves in multi‐ion species magnetospheric plasma

The growth and saturation of electromagnetic ion cyclotron (EMIC) waves is essential to the magnetospheric dynamics. Determining and isolating the effects of multiple ion parameters such as temperatures, anisotropies, and relative abundances is important for quantifying these processes in the magnetospheric plasma. In order to study these process, we utilize a 2.5‐D hybrid model (where ions are modeled with the particle‐in‐cell (PIC) method, and electrons are modeled as background neutralizing fluid) to study the nonlinear electromagnetic wave‐particle interactions of hot H+, cold H+, cold He+, and cold or hot O+ ions for a broad range of typical magnetospheric parameters. The excitation of EMIC waves is driven by the temperature anisotropy of hot H+ in our model. As a result, we quantify the parametric dependence of the linear growth, the nonlinear saturation level of perpendicular magnetic fluctuations, and the temporal evolution of the ion temperature anisotropies. We establish the relation between key plasma parameters and the saturated EMIC wave power, using either power law fits or a nonlinear regression method. We construct the dispersion relation of the waves using the results of the model and investigate the energy content in the various branches of the dispersion (k∥−ω space), showing that the different modes can generate wave power in different regions of k space. We find that large O+ concentration reduces the growth and saturated amplitude of the waves; but the waves are less sensitive to the temperature of the O+ in the temperature range relevant to the magnetosphere.
The current state of speckle imaging

Speckle imaging produces diffraction-limited images from ground-based telescopes. Recent advancements in detectors such as electron-multiplying CCDs (EMCCDs), have spawned a resurgence of this technique, greatly improving sensitivity and observing efficiency. The high angular resolution provided by speckle imaging can discern blended binary system contamination and validate suspected exoplanets discovered by the Kepler and K2 transit surveys. High-resolution follow-up will also be required for upcoming missions including TESS. Multiplicity can be determined along with separation, position angle, photometry, and contrast ratio. In this way, speckle imaging can validate even small, rocky planets like TRAPPIST-1 and constrain exoplanet radii and density. Some of the developments leading to this technique will be discussed in conjunction with recent significant papers, ongoing speckle imaging programs, and prospects for the future.
Design of Interval Type-2 Fuzzy-Based Sampled-Data Controller for Nonlinear Systems Using Novel Fuzzy Lyapunov Functional and its Application to PMSM

This paper presents interval type-2 fuzzy-based sampled-data controller for nonlinear systems using novel fuzzy Lyapunov functional. To do this, a type-2 fuzzy model is adapted for the nonlinear systems and a type-2 fuzzy-based sampled-data controller is designed. Based on the novel time-dependent Lyapunov–Krasovskii functional with membership functions, the sufficient conditions are derived to stabilize the proposed closed-loop system. The stabilization conditions are formulated in terms of linear matrix inequalities. Finally, in the numerical section, the proposed method is validated with nonlinear permanent magnet synchronous motors model which is formulated for reflecting the characteristics of the wind turbine. Besides that, we demonstrate the superiority of the derived sufficient conditions through the comparison with existing methods.
Disruption of Endochondral Ossification and Extracellular Matrix Maturation in an Ex Vivo Rat Femur Organotypic Slice Model Due to Growth Plate Injury

Postnatal bone fractures of the growth plate (GP) are often associated with regenerative complications such as growth impairment. In order to understand the underlying processes of trauma-associated growth impairment within postnatal bone, an ex vivo rat femur slice model was developed. To achieve this, a 2 mm horizontal cut was made through the GP of rat femur prior to the organotypic culture being cultivated for 15 days in vitro. Histological analysis showed disrupted endochondral ossification, including disordered architecture, increased chondrocyte metabolic activity, and a loss of hypertrophic zone throughout the distal femur. Furthermore, altered expression patterns of Col2α1, Acan, and ColX, and increased chondrocyte metabolic activity in the TZ and MZ at day 7 and day 15 postinjury were observed. STEM revealed the presence of stem cells, fibroblasts, and chondrocytes within the injury site at day 7. In summary, the findings of this study suggest that the ex vivo organotypic GP injury model could be a valuable tool for investigating the underlying mechanisms of GP regeneration post-trauma, as well as other tissue engineering and disease studies.
The role of metformin in the management of endometriosis: A systematic review and meta-analysis

Purpose: To analyze the activity of metformin in endometriosis, with a view to alleviating disease progression. Methods: A search was conducted using electronic databases such as CNKI, VIP, CBM, WANFANG, Embase, PubMed, Cochrane, and Web of Science from January 1980 to January 2022 for randomized trials involving any intrapartum fetal surveillance method. A network meta-analysis was performed within a frequentist framework, and it was assessed for quality and network inconsistency of the trials. A ninety-five percent confidence interval (CI) was used to report the relationship between metformin levels and patients with endometriosis. Results: Eight eligible studies which included 688 patients were evaluated in this meta-analysis. The primary indicators were treatment efficiency and CA-125 level. Metformin significantly increased treatment efficiency (SMD = 3.29, 95 % CI 2.01, 5.40, p < 0.00001). As expected, metformin also reduced the CA-125 level in endometriosis patients as a result (Odds Ratio, OR = -1.20, 95 % CI: -1.40 - 1.00, p < 0.00001). Conclusion: Metformin alleviates pains caused by endometriosis. However, some studies had scanty information about alleviating clinical symptoms other than basic medical research. More randomized controlled trials are needed to confirm treatment efficacy.
Two results on divisors on moduli spaces of sheaves on algebraic surfaces: generic Strange Duality on abelian surfaces and Nef cones of Hilbert schemes of points on surfaces with irregularity zero.

of Dissertation In the first part of this thesis, we consider a special version of Le Potier’s strange duality conjecture for sheaves over abelian surfaces, after other two versions were studied in previous literature. In the current setup, the isomorphism involves moduli spaces of sheaves with fixed determinant and fixed determinant of the Fourier-Mukai transform on one side, and moduli spaces where both determinants vary, on the other side. We first establish the isomorphism in rank one using the representation theory of Heisenberg groups. For product abelian surfaces, the isomorphism is then shown to hold for sheaves with fiber degree 1 via Fourier-Mukai techniques. By degeneration to product geometries, the duality is obtained generically for a large number of numerical types. Finally, it is shown in great generality that the Verlinde sheaves encoding the variation of the spaces of theta functions are locally free over moduli. In the second part, we discuss general methods for studying the cone of ample divisors on the Hilbert scheme of n points X , where X is a smooth projective surface of irregularity 0. We then use these techniques to compute the cone of ample divisors on X [n] for several surfaces where the cone was previously unknown. Our examples include families of surfaces of general type and del Pezzo surfaces of degree 1. The methods rely on Bridgeland stability and the Positivity Lemma of Bayer and Macr̀ı.
High resolution distance measurement using reverse frequency sample method

The spatial resolution of frequency-modulated continuous wave(FMCW) laser ranging technology is limited by the frequency sweep non-linearity. The typical method for suppressing the influence of sweep non-linearity is that using an auxiliary interference signal to sample the measurement signal at the equal frequency intervals. The ranging scale of this method is restricted by the optical path difference of the auxiliary interferometry. We have presented a reverse frequency sample method that using measurement signal to sample the auxiliary signal, the range can be acquired from the ratio of the optical path difference of the auxiliary interferometry to the frequency of the resample signal. The experiment has verified that the reverse frequency sample method can measure the distance longer than the optical path difference, increasing the available ranging scale compared to the typical frequency sample method. This method can also avoid the influence of frequency sweep non-linearity on the range profile. The range resolution is reduced to 50μm with the decreasing of the measurement range and auxiliary optical path difference. The range accuracy of the experimental system based this method is 57μm.
