State-of-the-art of geometric correction of remote sensing data: a data fusion perspective

The three-dimensional (3D) geometric processing and ortho-rectification of remote sensing (RS) data becomes a key issue as being the first step in multi-source multi-format data fusion in geographic information systems. The fusion of image data (visible and microwave, panchromatic and multi bands, polarimetric bands, passive and active, etc.), their metadata (GPS, star trackers, inertial system, lens and focal plane, etc.), the associated 3D cartographic data (ground control points, contour lines, digital terrain model (DEM), planimetric features, etc.) is thus a requisite to perform first 3D precise geometric correction and then the ortho-rectification process with DEM. This article presents an update of the state-of-the-art of geometric correction with the source of geometric distortions, the different mathematical models, the methods, algorithms and processing steps to track finally the error propagation during the fusion of the different RS and cartographic data from the image acquisition to the ortho-rectification processes.
A new filtering algorithm for lidar data fused with image segmentation information

The traditional LiDAR Point Cloud filtering and classification algorithms are mostly based on the elevation information, which are difficult to distinguish bare-ground and non-ground point with this single data source. In this article, fused image information such is used in the filtering process. Through the image segmentation, each segmentation object are extracted with the shape and spectral information, then these vector space objects and point cloud are matched and the decision tree is set up based on topology relationship for filtering. In order to test the performance of the proposed algorithm, test area with thick buildings and roads were applied, which could achieve a better filtering effect.
Neuroprotective impacts of chrysin against clonazepam induced cognitive deficits in male rats

The therapeutic effects of Clonazepam (CZP), a classic anti-anxiety drug, are accompanied by several neurodegenerations and neural disorders in patients. Also, Chrysin is a flavonoid that naturally exists in many plants and honey; it has various pharmacological effects, including anti-cancer, antioxidant, and anti-inflammations, and it has a neuroprotective effect. The purpose of this work is to evaluate the influences of chronic treatments with Chrysin on behavior and neurochemical fluctuations induced by CZP treatment. Forty male rats were classified into four groups with one of them acting as the control group receiving 1% Tween 80; the CZP group was treated with 2 mg kg −1 day −1 ; the Chrysin group was treated with 50 mg kg −1 day −1; the CZP + Chrysin group was treated with the same above-mentioned doses of CZP and Chrysin. All animals were orally treated every day for 6 weeks. Open field and Y maze tasks were performed before decapitation. Then, gamma-aminobutyric acid (GABA), glutamic acid, monoamines (norepinephrine, dopamine, and serotonin) and their metabolites (homovanillic acid, 3,4-dihydroxyphenylacetic acid, and hydroxy indoleacetic acid, respectively), and DNA fragmentation [8-hydroxy-2–deoxyguanosine (8-HdG)] were evaluated in the brain cerebral cortex, hippocampus, and striatum, while brain-derived neurotrophic factor (BDNF) and calcium ATPase (Ca-ATPase) were measured in the whole brain. The results showed that Chrysin treatment improves GABA, glutamic acid, monoamines, and their metabolites in the three brain areas, whereas it inhibits DNA fragmentation 8-HdG and BDNF and modifies downregulation of Ca-ATPase persuaded by CZP treatment at p < 0.05. Moreover, Chrysin treatment intensely reverses the consequent behavioral alternations which were elevated by Y maze and open field tests changed by CZP treatment. Overall, results recommended that Chrysin exerts anxiolytic-like effects similar to benzodiazepines and it can produce neuroprotective effects against CZP treatment.
Zurich Mini Cementless Total Hip Arthroplasty in 42 Small Breed Dogs and 8 Cats: Surgical Technique and Outcomes

Abstract This report aims to describe implant characteristics and procedure for implantation, and comment on and report the clinical outcomes in small dogs and cats using the new Zurich mini cementless total hip system. This study involved 8 cats and 42 dogs, with 3 cats and 6 dogs having bilateral total hip arthroplasties (THA). The mean body weight for cats was 6.5 kg, and the mean body weight for dogs was 9.2 kg. In the group of THAs in cats, capital physeal fracture was the reason for performing a THA in six cases (60%), hip dysplasia was the underlying reason in four cases (30%) and hip luxation in one case (10%). Among the 48 THAs in dogs, hip dysplasia was the underlying cause for performing THA in 27 cases (56%), avascular necrosis of the femoral head in 12 cases (25%), traumatic luxation with underlying hip dysplasia in 4 cases (8.5%), capital physeal fracture in 4 cases (8.5%), and traumatic femoral head fracture in 1 adult dog (2%). Seven postoperative complications were encountered, and all were solved without the need for explanting the prosthesis, except in one case because of the owner's decision. In conclusion, the Zurich mini cementless total hip system performed well in this study, with most dogs and cats having an excellent outcome and no patient being too small for the available implant sizes.
Fasting Versus Non-Fasting Total Testosterone Levels in Women During the Childbearing Period

Background Total testosterone in men should be measured in the fasting state early in the morning with at least two samples according to guidelines. For women, no such a recommendation is available despite the importance of testosterone in this demographic. The aim of this study is to evaluate the effect of fasting versus non-fasting state on the total testosterone levels in women during the reproductive period. Methods This study was conducted at Faiha Specialized Diabetes, Endocrine and Metabolism Center in Basrah, (Southern Iraq) between January 2022 to November 2022. The total enrolled women were 109; their age was 18-45 years. The presentation was for different complaints; 56 presented for medical consultation with 45 apparently healthy women accompanying the patients as well as eight volunteering female doctors. Testosterone levels were measured by electrochemiluminescence immunoassays using the Roche Cobas e411 platform (Roche Holding, Basel, Switzerland). Two samples were collected from each woman; one was fasting and another was non-fasting the following day, and all samples were taken before 10 am. Results For all of the participants, the mean ± SD fasting was significantly higher as compared to the non-fasting testosterone (27.39±18.8 ng/dL and 24.47±18.6 ng/dL respectively, p-value 0.01). The mean fasting testosterone level was also significantly higher in the apparently healthy group, (p-value 0.01). In women who presented with hirsutism, menstrual irregularities and or hair fall, no difference was seen in the testosterone levels between fasting and non-fasting states (p-value 0.4). Conclusion In the apparently healthy women of childbearing age, serum testosterone levels were higher in the fasting versus the non-fasting states. In women who presented with complaints of hirsutism, menstrual irregularities, and or hair fall, the serum testosterone levels were not affected by the fasting states.
Bridging the Understanding of Sustainability Accounting and Organisational Change

The contribution of Accounting, Management and Organisation Studies (MOS) to the acceleration of human-induced global ecological disruption is increasingly recognised. Hence, the proposed geological period of the Anthropocene calls for a profound rethink-ing of disciplinary epistemological, theoretical, and methodological grounds as well as research agendas (Bebbington et al. 2019; Ergene, Banerjee, and Ho ﬀ man 2021). For the past four decades, social and environmental accounting scholarship has been con-cerned with the potential of sustainability accounting and reporting to trigger transformative organisational change. Its impacts have been called into question inside and outside the ﬁ eld (Bebbington and Gray 2001; Gray 1992, 2010, 2019). Garcia-Torea, Larrinaga, and Luque-Vílchez (2022) show that the interest of organisational studies in the transformative potential of sustainability accounting is limited, especially when compared to the attention paid to this issue in the social and environmental accounting ﬁ eld. They argue that the relationship between SAR and organisational change is still an open question. The authors conducted an in-depth literature review in MOS and accounting journals of 53 papers focusing on the interplay between organisational change and SAR, with nine out of ten published in accounting journals. After laying out the main characteristics of the reviewed articles, they map these along ﬁ ve key features: theoretical frameworks, methods, SAR type (i.e. internal or external) , and, more importantly, the type of connection between SAR and change and the explanation provided. They build on this analysis to outline ﬁ ve bridges towards
Patterns of a creeping water-spout flow

Abstract This paper explains a mechanism of eddy formation in a slow air–water motion, driven by the rotating top disk, in a vertical sealed cylinder. The numerical simulations reveal nine changes in the flow topology as water volume fraction $H_{w}$ varies from 0 to 1. At $H_{w}$ around 0.8, there are two large regions of the clockwise meridional circulation, one in air and one in water. These regions are separated by two small cells of the anticlockwise circulation adjacent to the interface near the sidewall in water and near the axis in air. The air cell is a thin layer and topologically is a bubble–ring for $0.745 < H_{w} < 0.785$ . Alterations of this flow pattern are explored as (i) pressure increases, (ii) the bottom disk co-rotates and (iii) the top-disk rotation speeds up. This paper provides the physical reasoning behind the flow transformations; the results are of fundamental interest and can be utilized in bioreactors.
Has There Been a Recent Shallowing of Tropical Cyclones?

Many aspects of tropical cyclone (TC) properties at the surface have been changing but any systematic vertical changes are unknown. Here, we document a recent trend of high thick clouds of TCs. The global inner‐core high thick cloud fraction measured by satellite has decreased from 2002 to 2021 by about 10% per decade. The TC inner‐core surface rain rate is also found to have decreased during the same period by a similar percentage. This suppression of high thick clouds and rain has been largest during the intensification phase of the strongest TCs. Hence, these two independent and consistent observations suggest that the TC inner‐core convection has weakened and that TCs have become shallower recently at least. For this period, the lifetime maximum intensity of major TCs has not changed and this suggests an increased efficiency of the spin‐up of TCs.
Clofarabine in Pediatric Acute Relapsed or Refractory Leukemia: Where Do We Stand on the Bridge to Hematopoietic Stem Cell Transplantation?

Background Despite pronounced improvement in overall survival (OS) in pediatric leukemia, a proportion of patients continue to suffer from lack of response or relapse, and the management of such patients is exceedingly difficult. Immunotherapy and engineered chimeric antigen receptor (CAR) T-cell therapy have shown promising results in the course of relapsed or refractory acute lymphoblastic leukemia (ALL). However, conventional chemotherapy continues to be utilized for re-induction purposes whether independently or in combination with immunotherapy. Methods Forty-three pediatric leukemia patients (age < 14 years at diagnosis) consecutively diagnosed at our institution and got treated with clofarabine based regimen at a single tertiary care hospital between January 2005 and December 2019 were enrolled in this study. ALL comprised of 30 (69.8%) patients of the cohort while the remaining 13 (30.2%) were with acute myeloid leukemia (AML). Results Post-clofarabine bone marrow (BM) was negative in 18 (45.0%) cases. Overall clofarabine failure rate was 58.1% (n = 25) with 60.0% (n = 18) in ALL and 53.8% (n = 7) in AML (P = 0.747). Eighteen (41.9%) patients eventually underwent hematopoietic stem cell transplantation (HSCT); 11 (61.1%) were from ALL group and remaining seven (38.9%) were AML (P = 0.332). Three- and 5-year OS of our patients was 37.7±7.6% and 32.7±7.3%. There was a trend of better OS for ALL patients compared to AML (40.9±9.3% vs. 15.4±10.0%, P = 0.492). Cumulative probability of 5-year OS was significantly better in transplanted patients (48.1±12.1% vs. 21.4±8.4%, P = 0.024). Conclusions Though almost 90% of our patients proceeded to HSCT with complete response post-clofarabine treatment, yet clofarabine-based regimens are associated with the significant burden of infectious complications and sepsis-related deaths.
All‐Particle Multiscale Computation of Hypersonic Rarefied Flow

This study examines a new hybrid particle scheme used as an alternative means of multiscale flow simulation. The hybrid particle scheme employs the direct simulation Monte Carlo (DSMC) method in rarefied flow regions and the low diffusion (LD) particle method in continuum flow regions. The numerical procedures of the low diffusion particle method are implemented within an existing DSMC algorithm. The performance of the LD‐DSMC approach is assessed by studying Mach 10 nitrogen flow over a sphere with a global Knudsen number of 0.002. The hybrid scheme results show good overall agreement with results from standard DSMC and CFD computation. Subcell procedures are utilized to improve computational efficiency and reduce sensitivity to DSMC cell size in the hybrid scheme. This makes it possible to perform the LD‐DSMC simulation on a much coarser mesh that leads to a significant reduction in computation time.
A reversible averaging integrator for multiple time-scale dynamics

Abstract This paper describes a new reversible staggered time-stepping method for simulating long-term dynamics formulated on two or more time scales. By assuming a partition into fast and slow variables, it is possible to design an integrator that (1) averages the force acting on the slow variables over the fast motions and (2) resolves the fast variables on a finer time scale than the others. By breaking the harmonic interactions between slow and fast subsystems, this scheme formally avoids resonant instabilities and is stable to the slow-variable stability threshold. The method is described for Hamiltonian systems, but can also be adapted to certain types of non-Hamiltonian reversible systems.
Linear filtering system with arbitrary initial conditions

We consider linear filtering system with non-Gaussian initial condition. Two explicit and simple filtering formulae are obtained: one for the conditional density function of the estimated state and another for the conditional mean. Only 2n sufficient statistics need to be computed in real time, where n is the dimension of the state vector. It is shown that our formulae constitute natural extensions of the Kalman-Bucy filter. We also give an explicit solution to the derived Kolmogorov equation.
Some new results on optimal and suboptimal regulators of the LQ problem with output feedback

The LQ (linear quadratic) regulator problem with output feedback is considered. In the problem studies an output feedback control is determined such that the cost is J*, the optimal cost for the LQ problem with state feedback, or beta j* with some constant beta >1. A set of sufficient conditions is given for determining such optimal and suboptimal output feedback control laws. >
ON USING NONPARAMETRIC REGRESSION METHODS TO ESTIMATE CATEGORICAL OUTCOMES MODELS WITH MIXED DATA TYPES

Many data analysis methods are sensitive to the type of data under study. When we begin any statistical data analysis, it is very important to recognize the different types of data. Data can take a variety of values or belong to various categories, whichever numerical or nominal. However, there are two types of data, quantitative and qualitative (Categorical) data. The general and powerful methodological approaches for the analysis of quantitative data have been widely taught for several decades. While the analysis for qualitative data analysis have blossomed only in the past 25 years. The need for analysis of categorical data techniques has increased steadily in recent years, in economic, health, social science. However, analysis of categorical data models when the dependent variable binary or multinomial outcomes with mixed explanatory variables are complex. The main goal of this paper is to estimate a nonparametric regression model of the binary and multinomial outcomes models with mixed explanatory variables, it is based on nonparametric conditional CDF method and (PDF) method of bandwidth selection, presented by Li and Racine (2008). Then we have compared it with one of the most common method of parametric regression (the logistic regression model). The comparisons will be based on two criteria depends on their classification ability through Correct Classification Ratio CCR as well as their log likelihood value LLK. We conducted several simulation studies using generated random data (categorical discrete and continues) in order to investigate the performance of both the parametric model and the nonparametric model for binary and multinomial outcomes. Interesting results have been achieved in this work. Application on real-data have also been applied when there exist mixed variables. We make use of dataset of the Household Expenditure Survey (HES).
Development of a PET cyclotron based irradiation setup for proton radiobiology

An out-of-yoke irradiation setup using the proton beam from a cyclotron that ordinary produces radioisotopes for positron emission tomography (PET) has been developed, characterized, calibrated and validated. The current from a 20 μm thick aluminum transmission foil is readout by home-made transimpedance electronics, providing online dose information. The main monitoring variables, delivered in real-time, include beam current, integrated charge and dose rate. Hence the dose and integrated current delivered at a given instant to an experimental setup can be computer-controlled with a shutter. In this work, we report on experimental results and Geant4 simulations of a setup which exploits for the first time the 18 MeV proton beam from a PET cyclotron to irradiate a selected region of a target using the developed irradiation system. By using this system, we are able to deliver a homogeneous beam on targets with 18 mm diameter, allowing to achieve the controlled irradiation of cell cultures located in biological multi-well dishes of 16 mm diameter. We found that the magnetic field applied inside the cyclotron plays a major role for achieving the referred to homogeneity. The quasi-Gaussian curve obtained by scanning the magnet current and measuring the corresponding dose rate must be measured before any irradiation procedure, with the shutter closed. At the optimum magnet current, which corresponds to the center of the Gaussian, a homogenous dose is observed over the whole target area. Making use of a rotating disk with a slit of 0.5 mm at a radius of 150 mm, we could measure dose rates on target ranging from 500 mGy/s down to 5 mGy/s. For validating the developed irradiation setup, several Gafchromic® EBT2 films were exposed to different values of dose. The absolute dose in the irradiated films were assessed in the 2D film dosimetry system of the Department of Radiotherapy of Coimbra University Hospital Center with a precision better than 2%. In the future, we plan to irradiate small animals, cell cultures, or other materials or samples.
Clinical and histopathological characteristics of breast cancer and their epidemiological trends in Trichy, Tamil Nadu: a retrospective study

Background: Breast cancer despite being the 2nd most commonly diagnosed, with around 68,50,00 deaths globally in 2020, has only handful of resources on the baseline characteristics, along with clinical features and histopathological findings in India. Methods: A retrospective study was done among 52 patients who presented with breast cancer proven histologically, having identified nodal status by histopathology. All the data were collected from the medical record department. Results: The mean age was found to be 42.74±11.8 years ranging from 23 to 72 years. Majority of the patients were more than 51 years old. Invasive ductal carcinoma 73.08% was the most common type observed and majority of the patients presented with stage IIb 30.77% and IIIa 28.85%. The mean size of the tumour was found to be 4.12±2.09 cm and the mean number of nodes involves were 4.60. Luminal A 42.31% was the most common immunophenotype observed followed by 23.08% of luminal B and 23.08% triple negative and rest Her2neu positive. 90.38% of the patients underwent modified radical mastectomy. Breast conservative surgery was done only among patients with stage I and II. Invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) was most commonly observed in right side of the breast compared to left, with upper outer quadrant being the most common site. Conclusions: Thus, comparing the results of corelation with baseline characters helps in better understanding of the traits and presentation of breast cancer in women from rural environment in Tamil Nadu.
STUDY ON ESSENTIAL OIL COMPOSITION AND BIOLOGICAL ACTIVITIES OF ESSENTIAL OIL AND ETHANOL EXTRACT’S FROM ARTEMISIA SCOPARIA WALDST.et KIT GROWN IN MONGOLIA

Mongolia is rich in medicinal plants. Essential oils of aromatic and medicinal plants generally have a diverse range of activities because they possess many active constituents that work through a several modes of action. Artemisia, the largest genus of the family Asteraceae, has a number of effects against human and plant diseases [8]. This study was aimed to evaluate antioxidant, cytotoxic activities of aerial parts ethanol extracts from Artemisia scoparia Waldst.et Kit grown in Mongolia. The antioxidant and cytotoxic activities of the essential oil and ethanol extract was determined by using DPPH and MTT assays. The ethanol extracts showed higher antioxidant activity than essential oil. The essential oil of Artemisia scoparia Waldst.et Kit with a concentration of 150 mg/ml or 3μg/disk inhibits the growth of S.enterica 10.6±0.58 mm, B.subtillus 11.6±1.15 mm, and has a moderate bacterial activity.The half-lethal dose (IC50) 56.542 μg/ml is of essential oil of Artemisia scoparia Waldst. et. Kit, so essential oil of Artemisia scoparia Waldst. et. Kit is active in inhibiting of liver cancer cell line (HepG2). The half-lethal dose (IC50) 72.611 μg / ml is of essential oil Artemisia scoparia Waldst. et. Kit, which has the active in inhibiting the growth of human stomach cancer cell line (AGS). The results clearly showed that the essential oil presented satisfactory cytotoxic activity against human stomach cancer cell line AGS. Our work revealed that the ethanol extracts and essential oil of Artemisia scoparia Waldst.et Kit grown in Mongolia has potential as sources of new antioxidant, and cytotoxic compounds, respectively.
