Relationships are inherent in medicine and health. For example, lung functions are related to height, and greater weight gain in childhood among low birth weight children is associated with a higher chance of myocardial infarction. The methods for studying relationships are different for qualitative variables than for quantitative variables. You know by this time that a variable is considered quantitative when it is measured on a metric scale (continuous or discrete), whereas variables on nominal and ordinal scales as well as those that have broad categories on a metric scale are considered qualitative for most statistical purposes(1). There are two aspects in the study of relationships. One is the form or type of relationship and the other is the strength of relationship. The strength is generally measured by correlation in quantitative type of variables and by association in qualitative type. For example, different anthropometric measurements in children such as weight, height, mid-arm and calf circumferences are correlated. Symptoms in children of age 6 months to 1 year such as increased biting, ear-rubbing, decreased appetite for solid foods and mild temperature elevation are associated with teething. Some measures of strength of relationships for both qualitative and quantitative variables are discussed in Section 11.1. What do we actually mean by form of relationship? The form of relationship between weight gain during pregnancy and birth weight would be able to indicate how much increase in birth weight (y) to expect when the pregnancy weight gain (x 1 ) is 10 kg in one women opposed to 8 kg in another. This is an example of what is called simple regression in statistical sense because there are a total of only two variables in this case. The variables y and x 1 are called dependent and independent, respectively. Thus, the form of relationship is an expression of quantitative change in one variable per unit change in the other. It becomes from simple to multiple regression when the number of independent variables is more than one. For example, birth weight is also related to the other parameters such as maternal Hb level (x 2 ) and calorie intake during pregnancy (x 3 ). The type and expression of the regression may vary depending on the number of independent variables and whether the dependent variable (y) is quantitative or qualitative. These are discussed in Section 11.2. Computation of regressions, especially multiple type, involves intricate mathematical expressions. We avoid discussing these and advise use of computer programs to obtain such regressions. Our emphasis is mainly on the concepts and interpretation of such regressions. There is another type of relationship that is frequently encountered in the practice of medicine and health. This is between two or more measurements on the same variable obtained on the same subjects. Examples of this are: (i) presence or absence of a disease in a group of children diagnosed by two clinicians, and (ii) measurement by two devices, a newly devised and a conventional, for a nutritional anthropometry, such as mid-arm circum-ference. The problem under study in these situations basically is that of agreement between two or more observers, methods, laboratories, etc. Methods of assessing such agreement in both quantitative and qualitative variables are presented in Section 11.3.

This paper focuses on the design of an acquisition device for a thought controlled robotic arm. The key lies in the mapping of the EEG signal of the subject to the 2D cursor to achieve the objective. We designed a low cost and reliable signal acquisition device to attain the EEG signal and mapped it to cursor control through signal processing. The advantages of the design are (i) cost prohibitive and reliability (ii) attains a high-resolution EEG signal after transmission for signal processing.


Objective To explore the influence of postural control training on plantar pressure and balance function of hemiparalysis patient.Methods Twenty-four cases of hemiparalysis patients were selected and divided into two groups of traditional group(TG) and balance group(BG) and had been taken postural control trainings.Novel Zebris pressure test platform was used to examine the pressure peak value(PPV),average pressure(AP),ellipse track length(ETL) of pressure center deviation including ellipse area(EA) after postural control trainings.Results After two different training methods:1Compared with TG,PPVs of front half foot and back half foot of unaffected side were both decreased significantly(P 0.05) in BG.The pressure peak value of affected side decreased significantly while the affected side front half decreased significantly(P 0.05) and back decreased not significantly in this group(P 0.05).2Compared with TG,AP of front half foot in unaffected side decreased significantly and that in back half foot increased significantly(P 0.05) in BG.But,there was no great change in both the front and back half feet in affected feet(P 0.05).3Compared BG with TG,EA,ETL and ratio between ETL and EA decreased significantly(P 0.05).Conclusion 1After two postural control trainings,there is no significant alteration on contact mode between feet and ground,and feet pressure distribution condition.Body's methods to maintain balance have not been changed.2Both feet pressure balance abilities of hemiparalysis patients have been improved after two postural control trainings that indicate they are effective to increase hemiparalysis patients' balance function.3Steady trainings in BG promote the improvement of balance function and coordination ability.4BG had obvious advantages than TG in regaining balance adjustment function.


In this paper, we address the task of predicting stock prices using the market sentiments extracted from Twitter. We propose MLStock, a multi-layer framework that models the market sentiment with the stock layer, the sector layer, and the market layer using the Gated Recurrent Unit (GRU), and use the sentiment to make directional prediction on stock price. Existing methods consider stocks individually, and might miss the signals in the current market sector which will affect the stock later. In contrast, our model summa-rizes the sector and market states through individual states and shows an improvement over traditional machine learning methods.


This study aims to make a complementary review of recent relief item logisticsresearches on the post-disaster stage, trends and practical solutions on humanitarian supply chains (HSC) post-disaster stage, focusing on gaps and future research directions.The paper provides a definition of HSC and its stages; emphasizes its difference from a commercial supply chain; then continues with a presentation of a post-disaster HSC map. Then, based on an updating literature review and evaluation of ongoing studies, concludes with main findings and gaps, and suggestions about future research directions. The article serves as an update on previous literature reviews in humanitarian logistics. Our analysis shows that there are still considerable gaps in practical applications; in the incorporation of vulnerability and safety aspects of relief item distribution such as robbery and despoliation; in the effects of dynamic road availability updates; in multi-period, multi-level, and multi-objective relief item distribution; in the considerations of social costs; in the incorporation of human behavior; and in the needs of cross-services.


Adaptive bit rate (ABR) streaming is one enabling technology for video streaming over modern throughput-varying communication networks. A widely used ABR streaming method is to adapt the video bit rate to channel throughput by dynamically changing the video resolution. Since videos have different ratequality performances at different resolutions, such ABR strategy can achieve better rate-quality trade-off than single resolution ABR streaming. The key problem for resolution switched ABR is to work out the bit rate appropriate at each resolution. In this paper, we investigate optimal strategies to estimate this bit rate using both quantitative and subjective quality assessment. We use the design of bitrates for 2K and 4K resolutions as an example of the performance of this strategy. We introduce strategies for selecting an appropriate corpus for subjective assessment and find that at this high resolution there is good agreement between quantitative and subjective analysis. The optimal switching bit rate between 2K and 4K resolutions is 4 Mbps.


Interpenetrating polymer networks (IPNs) composed of hyaluronic acid and poly(vinyl alcohol) hydrogels were prepared, and the influence of water and the drying kinetics were investigated. The IPN hydrogels were characterized with thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The glass-transition temperatures of the IPN hydrogels decreased with increasing water content. The bound water was the sum of the nonfreezing bound water and freezing bound water. From the DSC melting curves, the values of the total water and freezing bound water were evaluated for IPN hydrogels containing large amounts of water. At the same time, the bound water value was estimated with TGA. In the TGA curves, one-step and two-step weight losses, corresponding to free water and nonfreezing bound water, were observed. The bound water of the hydrophilic polymers broke the hydrogen bonding between the hydroxyl groups of the polymers. The swollen IPN hydrogels exhibited relatively high bound water contents (43.04–59.17%) by DSC and TGA. The bound water contents of the dry IPN hydrogel films were 10.2–15.29% by TGA. The drying reaction rate constant of the IPN hydrogel increased with increasing temperature. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 92: 1467–1472, 2004


The case is presented of a man who, at the age of 63, began to complain of joint pain. The clinical picture of polymyositis gradually developed, and three years after the onset of the joint pain a carcinoma of the prostate was diagnosed. The rheumatic complaints improved during treatment with indomethacin and estrogen. Early in the disease a repeatedly abnormal x‐ray finding in the duodenum raised the possibility of a carcinoma of the pancreas. At the height of this symptomatology, the patient twice exhibited neurological signs, diagnosed as a small stroke; an abnormal EEG was found immediately following the second attack and one year later.

We study globularily generated double categories. The condition of a double category being globularily generated is a finiteness condition generalizing the condition of a double category being trivial. We establish analogies between the way trivial double categories and globularily generated double categories relate to general double categories. We organize globularily generated double categories into a 2-category and we prove, among other things, that 2-category of globularily generated double categories is a strictly 2-reflective sub 2-category of an appropriate sub 2-category of 2-category of double categories.


We present the first results of the prototype of a silicon tracker with trigger capabilities based on a novel approach for fast track finding. The working principle of the "artificial retina" is inspired by the processing of visual images by the brain and it is based on extensive parallelisation of data distribution and pattern recognition. The algorithm has been implemented in commercial FPGAs in three main logic modules: a switch for the routing of the detector hits, a pool of engines for the digital processing of the hits, and a block for the calculation of the track parameters. The architecture is fully pipelined and allows the reconstruction of real-time tracks with a latency less then 100 clock cycles, corresponding to 0.25 microsecond at 400 MHz clock. The silicon telescope consists of 8 layers of single-sided silicon strip detectors with 512 strips each. The detector size is about 10 cm × 10 cm and the strip pitch is 183 μm. The detectors are read out by the Beetle chip, a custom ASICs developed for LHCb, which provides the measurement of the hit position and pulse height of 128 channels. The "artificial retina" algorithm has been implemented on custom data acquisition boards based on FPGAs Xilinx Kintex 7 lx 160. The parameters of the tracks detected are finally transferred to host PC via USB 3.0. The boards manage the read-out ASICs and the sampling of the analog channels. The read-out is performed at 40 MHz on 4 channels for each ASIC that corresponds to a decoding of the telescope information at 1.1 MHz. We report on the first results of the fast tracking device and compare with simulations.


Abstract As a result of autocorrelation, static risk measures such as value at risk and Conditional Value at Risk (CVaR) are time inconsistent and can thus result in inconsistent decisions over time. In this article, we present a time-consistent dynamic CVaR measure and examine it in the context of a newsvendor problem with autocorrelated demand. Due to the concavity of our CVaR measure, the dynamic program formulation associated with our dynamic newsvendor problem is not immediately separable. However, by exploring certain properties of the dynamic CVaR measure and underlying profit function, our dynamic program can be transformed into a sequence of (single-period) risk-averse newsvendor problems that depend on the observed demand history. By examining the structure of the optimal order quantities, we find both intuitive and counterintuitive results. When demands are positively correlated, the optimal order quantity is monotonically increasing in the degree of risk aversion. However, when demands are negatively correlated and the underlying cost structure satisfies certain conditions, the optimal order quantity is no longer monotonically increasing in the degree of risk aversion. Instead, the optimal order quantity is a decreasing (increasing) function of the degree of risk aversion when it is below (above) a certain threshold. We also show that these results continue to hold when demands follow a general ARMA process, and when inventory carryover is considered.


BACKGROUND AND AIM OF THE STUDY
Atrial fibrillation (AF) is common in patients submitted for transcatheter aortic valve implantation (TAVI), and these patients are at higher risk of developing conduction system disturbances requiring pacemaker (PM) implantation. Conventional predictors for PM use in this population have limited applicability. It was hypothesized that a post-procedural heart rate reduction could gauge the degree of atrioventricular (AV) node injury, and that this would be a clinically useful predictor of a need for PM.

METHODS
All consecutive patients submitted for TAVI between December 2009 and August 2015 were included prospectively in a local registry. Clinical and electrocardiographic data and procedural details were recorded, and patients in sinus rhythm or with pre-existing PM were excluded. Heart rate (HR) at the start and end of the procedure were used to assess post-procedural HR reduction by calculating the HR ratio (HRratio = HRend/HRstart). The relationship between previously described predictors of PM, HRratio and implantation of a permanent PM during the 30 days after TAVI were analyzed using the Wilcoxon ranksum test and receiver operating characteristic (ROC) curve.

RESULTS
A total of 102 patients was submitted for TAVI, 24 of whom had AF and no previous PM. Of the latter 24 patients, 10 (41.6%) received a PM during the 30 days after TAVI. Conventional predictors of permanent PM such as male gender, left anterior hemiblock and right bundle branch block were not significantly associated with PM implantation. The HRratio was significantly lower in patients submitted for PM implantation (median 0.76, IQR 0.68-0.86 versus 1.18, IQR 1.10-1.26; p <0.001; Wilcoxon ranksum test). ROC curve analysis of the HRratio showed a good discrimination for the need of PPM with a c-statistic of 0.93. An optimal cut-off value of 0.9 predicted the need for PM implantation with a sensitivity of 90% and specificity of 92.8% CONCLUSIONS: Conventional predictors of PM after TAVI were not associated with PM implantation in patients with AF. The fall in post-procedural HR was significantly associated with PM implantation, with an HRratio cut-off value of 0.9 accurately predicting a need for PM within 30 days.

The interest in this derivative is related to the possibility of its further functionalization via Suzuki coupling as well as it being a possible intermediate for the generation of a C61 unit.


Background:   Although incidence of femoral shaft fracture in children is less than 2%, treatment of fracture shaft of femur is controversial. Material and Method:   In this study we divide 30 patient in to two groups blindly and treat group I with retrograde titanium elastic nail (TEN) and group II with early external fixator. We have followed these patients for nine months and compile their results after noting the time of union, weight bearing and also the parents satisfaction with a questionnaire.  Results:   Duration of hospital stay was 4.7 days in group I and 2.8 days in group II. All the fractures healed satisfactorily. The average time for healing in the group I was 43.4 days and 70.26 days in group II. The average time for full weight bear-ing along with external fixator was 26 days while for group I was 42.7 days. Parents are more satisfied with intramedullary TEN. Conclusion:   TEN is better option than that of external fixator for the management of fracture shaft of femur in children. Patients and their parents are more satisfied with TEN as compare to heavy external fixators.


Advances in the study of tribo-corrosion of materials in recent years have included the development of mechanistic maps, showing the transitions between the regimes as a function of the main process parameters. In such cases, maps have been constructed in both two and three dimensions. There are now a variety of modelling algorithms which may be used to map a range of performance indicators over a multi-parameter space. The interactions of tribo-corrosion in biological environments are becoming of increasing importance.

We use the light‐front machinery to study the behavior of a relativistic free particle and obtain the quantum commutation relations from the classical Poisson brackets. We argue that the usual projection onto the light‐front coordinates for these from the covariant commutation ralations does not reproduce the expected results.

Whey protein concentrate hydrolysates, capable of inhibiting the activity of angiotensin-converting enzyme, were prepared in the present study. Several parameters, such as type of enzyme, enzyme:substrate ratio, and use of ultrafiltration were evaluated. The angiotensin-converting enzyme inhibitory activity was observed only after the enzymatic treatment and high rates of inhibition were obtained, ranging from 17.29 to 91.88%. Most hydrolysates obtained with pancreatin showed higher angiotensin-converting enzyme inhibitory activity than those obtained with papain both in the absence and presence of ultrafiltration. The smallest enzyme:substrate ratio for pancreatin resulted in better angiotensin-converting enzyme inhibitory activity values. The use of ultrafiltration proved to be disadvantageous for inhibitory activity of hydrolysates obtained with papain.

Abstract Laboratory assays were conducted to assess the potential of pymetrozine, a novel azomethine pyridine insecticide, against the brown planthopper, Nilaparvata lugens (Stål) (Homoptera: Delphacidae). All nymphal instars were treated with the pymetrozine concentrations of 400, 200, 100, 50, 25 mg/l, and then maintained in incubators at 26 ± 1°C on a photoperiod of 16:8 h (L: D). At 24, 48, 72, and 120 h after treatment, mortality was recorded. Greater numbers of nymphs were killed at a faster rate with the higher concentrations (mortality of 70.7% with 400 mg/l and 63.8% with 200 mg/l at 24 h, first -second) than at the median concentrations (mortality of 51.7% with 100 mg/l and 50% with 50 mg/l at 24 h, first -second) and the lower concentration (mortality of 25.9% with 25 mg/l at 24 h, first -second), whereas mortality in the control remained low (3.3% with distilled water at 24 h, first -second). The first and second instars were the most susceptible with median lethal concentrations [LC50] of 76.3, 35.5, 26.6 and 21.96 mg/L at 24, 48, 72 and 120 h after treatment, respectively. Fifth-instars were the least susceptible with the LC50 values of 5,887.53, 758.41, 236.15 and 67.23 mg/L at 24, 48, 72 and 120 h after treatment, respectively. The LC50s of the third - fourth instars were 1737.89, 601.6, 96.21 and 50.14 mg/L at 24, 48, 72 and 120 h after treatment, respectively, and were significantly greater than those of the first - second instars. These results indicate that pymetrozine would be an effective alternative for the control of brown planthopper.

Aerial photography began long before the Wright brothers first flew an airplane in 1903. Lifted aloft by balloons and/or kites, cameras snapped aerial photos of Paris and Boston as early as the 1860's. One of the early pictures shows San Francisco burning after the 1906 earthquake. Here are some of the most dramatic and significant of the early photos.


Volitional use of the paretic upper-extremity after hemiparetic stroke is necessary for positive functional and neurological improvement. Unfortunately, much of the recovery process occurs outside of the purview of the trained clinician. Thus, maximizing recovery necessitates the development of tools that can monitor, and eventually intervene in, motor performance for individuals in ambient settings. The goal of this study is to evaluate the ability of tools developed to monitor performance in a lab to reveal meaningful information regarding performance in ambient settings. Using spectral analysis techniques developed for in-laboratory settings, we perform a case study analysis of an individual with chronic hemiparetic stroke. In particular, we evaluate the relationship of temporal and spectral kinematic characteristics of performance and the amount of limb use of the paretic and non paretic arms to determine function over the course of a 3-day monitoring period. By comparing kinematics to the amount of limb use, we describe the meaningfulness of our spectral measures for monitoring in-home performance. We find that spectral measures sensitive to performance differences in the paretic and non paretic limbs, in the lab, are also sensitive in the home setting. This may indicate that these tools can be used to evaluate motor performance in ambient settings, and reveal the progression of motor recovery in the home setting.


Unexpectedly high amounts of aminium salts have been detected in ambient aerosol particles, prompting investigations into their role in new particle formation and nanoparticle growth. Amine uptake and particle-phase processes, including the effects of phase state and non-ideal mixing, are poorly understood. In this study, we conducted kinetic multi-layer modeling of dimethylamine (DMA) uptake by crystalline and aqueous ammonium sulfate (AS) and mixed ammonium sulfate–sucrose particles based on measurements at different relative humidity (RH) values. The temporal evolution of particle mass increases and the humidity dependence were successfully reproduced by considering the amine/ammonium exchange reaction and formation of hygroscopic dimethylaminium sulfate. Thermodynamic equilibrium predictions suggest that aqueous sucrose and AS mixtures undergo phase separation at RH < 94%. The kinetic model simulations reveal that DMA uptake is limited by diffusion of DMA and AS through a viscous sucrose-rich shell at...


Reproducing measurements of the scattering mean free paths for energetic particles propagating through the solar system has been a major problem in space physics. The pioneering work of Bieber et al. (1994) provided a theoretical explanation of such observations, which, however, was based on assumptions such as the questionable hypothesis that quasi‐linear theory is correct for parallel diffusion. By employing a hybrid plasma‐wave/magnetostatic turbulence model, a test‐particle code is used to investigate the scattering of energetic particles. The results show excellent agreement with solar wind observations.


The SARS-CoV-2 virus is the main cause of the pandemic viral pneumonia known as COVID-19. Some studies suggest that, in this disease, lymphopenia is the most common sign of infection, as well as increased CRP and IL-6 caused by a cytokine storm directed at the lungs. Therefore, the hypothesis of the study is to make a systematic revision of scientific studies linked to the immunological phenomenon known as COVID-19.
Objectives: The main aim is to study the cytokine storm of COVID-19, as well as to determine the role of IL-6 and T-lymphocytes.Methods: A search strategy was made through the PICOS questions, based on the PRISMA method. The MeSH terms were looked up on PubMed, Google Scholar and SciELO (2019-2021). The level of quality was sought according to the ranking of Scimago institutions, and the H index of the journals was assessed.
Results: 43 articles were included, and clinic, diagnosis, treatment, and pathogenesis were compared. A decrease in TCD4 / CD8 lymphocytes was shown in patients with severe disease, as well as an increase in IL-6 and CRP.Conclusions: The immunological phenomenon known as COVID-19 is characterized by lymphopenia and an increase in IL-6 amongst critically ill patients. Monitoring those parameters could help to understand the progression of the COVID-19 disease.


This paper reviews and analyzes the literature on agency theory in terms of the nature of the problem and its implications for management. Finance theory posits that the goal of economic organizations is to maximize stockholders' wealth. Attaining this goal was not an issue when owners were also managers. But since World War II corporate ownership world‐wide has become increasingly diffused. By 1969 only 15% of the largest U.S. non‐financial institutions were owned by their managers. This change raises the issue of the relationships between owners and managers. To what extent do managers act on their own behalf rather than the owners as prescribed by finance theory? Several studies indicate that managers substitute their own interests in place of the shareholders. This is possible because managers possess more information about the firm, control the election procedure to the Board of Directors, and the shareholders are widely dispersed. This phenomenon is called an agency problem. According to Jensen and Meckling an "agency problem" exists when managers own less than 100% of the firm. With less than 100 per cent ownership, managers can shift part of the cost associated with decisions made in their own interest. Clearly these conditions are common in major corporations of the world where global markets require raising large amounts of capital for the research, development, and production facilities required to remain competitive.


This paper presents a new method of recognition of isolated Chinese word. Here a local feature of an input utterence to be compared with an appropriate part of every reference template.Depending on the result of local comparision(pretest), the system associates the input utterance with a sebset of recognition vocabulary, which is less than the vocabulary(set) always. Then the input utterence to be compared with the contents of the subset only, not with all templates in the vocabulary. Because the linear shift matching and a tenth of utterance length is used for ocal comparasion, the computation quantity of this stage isn't comparable to that one for word matching by dynamic programing, therefore the new method of recognition can save much time for DP matcaing. An important problem discussed here is how to establish a subset system, which can provide a subset with appropriate size and contents for every word in the recognition vocabulary. Especially, it must be easy to establish when a vocablary or a speaker is changed. In our investigation a special algorithm was used to make the system experienced in given vocabulary and speaker automaticlly. It was based on statistics of intra-word and inter-word local distance of each word in given vocabulary nd for given speaker. A number of repetation of utterence for the vocabulary is necessary for experince mentioned above. The recognition accuracy provided by the new method was equal to that one provided by typical method using word emplates directly, it was 98.33% for the best score and 94.72% for the worst. But the time-consumption of the associative method was fourth-thirth as much as it was taken by the typical method.


Factors influencing results of objective hearing examination in children, i.e. auditory evoked potentials, based on own experiences are presented. "Cross-check" principle as well as observation of dynamic changes concerning development of communicative process should be taken into the consideration.


The study on soil heavy metal content of apple orchard in gully region of the loess plateau showed that high input and different apple tree ages have an obviously effect on soil heavy metal content and its migration.The soil Cu content increases along with the tree age increases.The input and output of soil Cu tends to be balance when the apple tree have planted more than 20 years,and the Cu content change is very small,and the topsoil Cu content is higher than the other soil layers.The soil Cr content increases progressively along with the tree age in a line,in 0~20 cm,20~40 cm and 40~60 cm soil layer of 36 year orchard,Cr content increased by 27.14%,17.09% and 19.17% compared to the 6 year orchard,respectively.The soil Cd content increased firstly,and then reduced.The main origin of soil Cd is the phospate fertilizer iuput.In deep soil layer of apple orchard,the Cd content peak appears ahead of time than that in the topsoil.Soil Pb content is higher in 15~26 year apple orchard.Take 15 year as a turning point,soil Hg content change present different tendency on the different soil layers.Soil As content reduced when the tree age was little than 15 year,and it increased when the tree age was between 15 year and 20 year,and it changed a little after planted 20 years.The change of As content between soil layers was not significantly.


The study states and solves a sources detection problem at the origin of a peak of pollution based on a scattering model of the pollutants in the air. The used model is discretized spatially in 3D and temporally, leading us to a direct solution of dispersion in algebraic form. It is thus expressed by a time varying multi-source state space representation. Finally, the F.I.R. multichannel transfer matrix is the base of estimations and detection. Then, the solution of the maximum likehood has been expressed, we tackle the problem of monosource detection for a probability of false alarm and threshold of detection given. We propose then a decision rule for the multi-source case, to determine the active sources and the flows among a whole of potential sources. Results are illustrated by tests starting from synthetic and real observations.

Abstract Introduction: Systemic infection leading to multiorgan failure during neutropenia is one of the leading causes of treatment-related mortality among children receiving chemotherapy. Reliable markers are needed to diagnose or rule out infection, to reduce the empirical use of broad-spectrum antibiotic therapy. Aims and Objectives: The aim is to compare the role of interleukin-6 versus C-reactive protein (CRP) as markers of sepsis in febrile neutropenia in pediatric patients while on chemotherapy for malignancy. Materials and Methods: This was a prospective observational study carried out in the Department of Paediatrics of a tertiary care Hospital in South India. All children with malignancy in the age group from 1 month to 18 years diagnosed to have febrile neutropenia during any phase of chemotherapy were included in the study. Multiple episodes of febrile neutropenia in the same child were analyzed as separate episodes. Results: Thirty-two episodes of febrile neutropenia were analyzed. There were 7 microbiologically documented infections (MDI), 19 clinically documented infections and 6 episodes of fever of unknown origin. Out of the 7 MDI, 5 were Gram-negative sepsis and 2 were Gram-positive sepsis. Gram-negative sepsis had a much higher median IL-6 value (169) than Gram-positive sepsis (17.5) and sterile blood cultures (52). However, median value of CRP was only slightly higher in Gram-positive sepsis (85.5) than in Gram-negative sepsis (60.7) and sterile blood cultures (44.2). Conclusion: In this study, higher IL-6 values predicted Gram-negative sepsis better than CRP.


Capacitive deionization (CDI) is a relatively new water desalination technology that has the potential to overcome some of the drawbacks of the more established deionization processes. Unlike ion exchange, it does not require chemicals for regeneration and it does not involve membranes and high pressures like that of reverse osmosis. Instead, CDI relies on an electrosorption/desorption process. It functions by passing an electrolyte solution through a pair of electrodes with an applied voltage. The positive electrode attracts the negatively charged species and the negative electrode the positively charged species. This small separation of charge between the electrode's surface and the oppositely charged ions forms an electrical double layer. Therefore, not only does the CDI process produce deionized water it also stores energy in the form of an electrical double layer capacitor. Typically, CDI systems use two identical high surface area carbon electrodes (symmetric system). The CDI system described here utilizes a different nanoporous metal oxide coating on each of the carbon electrodes in the pair (asymmetric system). One of the carbon substrates is coated with a nano-porous thin film of SiO2 and the other with a film of Al2O3. The choice for these two oxides is based upon their zeta potential in the pH range of natural waters (6.0-8.0); the SiO2 will have a highly negative surface charge and that of the Al2O3 highly positive. This difference in surface charge will be of particular importance once the electrodes become saturated with ions and must be regenerated. To quickly regenerate the electrodes, a potential opposite in polarity to that of removal is applied to electrically repel the ions off the electrodes. During this regeneration the surface charge of the coatings prevent the ions from desorbing off of one electrode and adsorbing onto the other electrode directly across from it. In addition to surface charge, the metal oxide coatings also have the ability to significantly increase the surface area of electrodes that utilize carbon substrates with relatively low surface areas. This allows for the potential use in CDI of carbons with favorable qualities such as high conductivity and durability, but may otherwise be deemed unusable because of their low surface areas.


Purpose: To investigate the changes of electroretinogram (ERG) at baseline and during the first 3 injections of intravitreal bevacizumab in central retinal vein occlusion (CRVO) patients. Methods: Thirteen eyes of 13 CRVO patients who received 3 injections of intravitreal bevacizumab at 6-week intervals and who could be examined for visual acuity, optical coherence tomography and ERG at 4 weeks after each injection were included in the present study. In addition, the ERG results of the unaffected fellow eyes group at 4 weeks after each injection were compared with the CRVO eyes group. Results: Amplitudes of rod b wave, a and b waves of maximal combined response and cone response, oscillatory potentials and 30-Hz flicker significantly decreased in the CRVO eyes group than the fellow eyes group at 4 weeks after each injection ( p < 0.001). After injection, amplitudes of all the above-mentioned ERG parameters gradually increased during the 1st and the 2nd injection ( p < 0.001). However, there was no significant difference at 4 weeks after the 2nd and 3rd injections ( p > 0.05). Conclusions: After intravitreal bevacizumab injection, macular functions significantly improved and amplitudes of all ERG parameters gradually increased in CRVO patients.

This paper study a supply chain system composed of a machine, a purchase warehouse, a vehicle and customers that demand a random quantity of products. We assume that the customers are located in urban areas and the demands are delivered by a green vehicle. Two cases of green transport are considered: in the first case the transport is ensured by an electric vehicle and the second case by a photovoltaic vehicle. The objective of this paper is to provide a performance evaluation system that allows choosing the suitable case according to the indicators of interest such as transport costs or the maintenance costs of vehicle. To describe both cases, a discrete flow model is adopted that takes into account the machine and vehicle failures, the quantity to deliver and the vehicle maintenance actions. Both cases of the green vehicle are simulated and the total cost of the supply chain of each case is determined. Numerical results are presented to discuss the choice of the suitable case. Also an optimization study of the supply chain system in the second case is presented.


Cultural bias means individuals judge and interpret a phenomenon according to values that are inherent in their own culture. The same event may be perceived differently by individuals with different cultural backgrounds. This study systematically tests for the presence of cultural differences in the perception of foreign policy events. Using a web survey with a split-sample of Chinese and US foreign policy experts, four domains of foreign policy are explored: sanctions; border violations; foreign aid; and trade agreements. The findings indicate general agreement between Chinese and US experts in the classification of foreign-policy events as cooperative, neutral, or conflictive. In regard to more specific foreign-policy scenarios, the picture is more differentiated. In the case of economic sanctions and border violations, there appears, again, to be general agreement as to the degree of conflictiveness of these events. In addition, perception does not appear to be influenced by collective self-esteem, in the sense that responses remain similar whether the event is described in abstract or country-specific terms. In the case of trade agreements and foreign aid, by contrast, there is a divergence in Chinese and US perceptions in regard to contextual factors such as conditionality and enforcement. Overall, the study suggests that while culture rarely affects the general perception of foreign-policy events, it does play a role in the perception of more complex concepts, such as conditionality and enforcement, that structure the context and meaning of those events.


In the literature it is well known that the produced high-order harmonics inherit certain properties from the driving laser especially in terms of spectral characteristics [1] , therefore introducing modulation in the generating laser spectrum we can have significant impact on the high harmonic generation process [2] , [3] .


An automated method is described, using standard continuous flow techniques, for the determination of urine fluoride ion concentration using a fluoride ion selective electrode. It is shown that the kinetics of the electrode response to changes in fluoride ion can be used for the accurate measurement of fluoride ion concentration in urine, and that equilibration of the electrode response is not a prerequisite for the measurement of fluoride ion. Recovery experiments are in the range 83 to 90%; in-batch precision is between 0·9 and 1·6% and carryover 2·5% or less.


This paper aims to examine the regional dynamics that further consolidated Israel's national security in the Middle East in the aftermath of the Arab Spring, reflecting upon the nuclear challenge between Iran and Israel and Iran's expanding activities in the region.,To prove the central argument, the study uses a conceptual framework that centers on deterrence as the main approach used by states to consolidate their influence in the Middle East region.,Iran's nuclear progress and influence in the region has strengthened Israel's security and fostered an unprecedented open rapprochement led by USA efforts with the Gulf regimes.,The paper draws particular attention to the Iran–Israel nuclear competency, and the Israeli preferred policy options regarding Iranian activities in the region amid turbulent Middle East. In addition, the paper offers insight to the regional dynamics that further consolidated Israel's national security in the region while maintaining a status of Arab vulnerability and backwardness.


Recent work has identified that circumstances of equipment operation can radically change condition monitoring data. This contribution investigates the significance of considering circumstance monitoring on the diagnostic interpretation of such condition monitoring data. Electrical treeing partial discharge data have been subjected to a data mining investigation, providing a platform for classification of harmonic influenced partial discharge patterns. The Total Harmonic Distortion (THD) index was varied to a maximum of 40%. The results show progressive development for interpretation of condition monitoring data, improving the asset manager's holistic view of an asset's health.


One objective of the International Geosphere-Biosphere Programme is to provide a scientific basis for sustainable development policies. Land use change and ecohydrology are important components of this scientific basis, but predicting change is difficult because of the scale and complexity of the interactions between non-linear ecohydrological and socio-economic processes at different spatial and temporal scales. A systems framework, the Ecosystem Approach, has been developed to conceptualize these interactions for the purpose of providing information for sustainable development policy. The Ecosystem Approach combines the dynamics of the Holling figure-eight model -- a conceptual model of dynamics that stresses discontinuous change and destruction as an internal property of the system - and the properties of self-organizing systems with the socio political aspects of decision making. The Ecosystem Approach highlights the problems of managing change in complex systems when that change may involve unpredictable shifts to a different attractor. Although there are methods available to detect the occurrence of such shifts, both detection and modelling are complicated by the presence of semi-stable attractors. When a model or an ecosystem is on a semi-stable attractor, it may appear to remain stable for an extended period prior to changing as a consequence of inherent instabilities. When the shift to a new attractor occurs, it is quite sudden and unpredictable. A technical discussion on prediction under conditions of semi-stability and chaos is included because it enhances our understanding of the role of surprise in ecosystems, as well as the utility of simulation models. The principles of the Ecosystem Approach are derived from the theoretical discussion and an example of a land use policy in the Huron Natural Area in south-western Ontario. These principles provide a clear role for scientific research, and particularly simulation modelling, within the larger context of policy and land use management.


An increasingly dynamic era forces every individual to be more creative in seeking opportunities in the intense economic competition. In order to balance all conditions, we are required to work hard in order to increase the economy and the welfare of workers. Things you can do, start from opening your own business or joining a partner. In this digital era, accounting applications are strongly recommended to be used by SME business actors so that micro SMEs in Indonesia can monitor all SME financial activities. The Lamikro application provides flexible and easy-to-use access, with many user-based options. Mr. Chaef is the owner whose address is Mr. chaef is the owner of KRE Cell having his address at Pasar Aviari Blok D2 no 1 has not yet implemented accounting in his business. This business only makes business expenses and income manually so that if employees commit fraud it is difficult to detect it. The decline in sales in the Covid-19 era has made this business need an injection of funds from banks, but it is hampered by the absence of financial reports for this business. KRE Cell's Statement of Financial Position and Profit and Loss has been prepared using the Lamikro Application. Although the background of business actors is not in the accounting field, they have a desire to study the Lamikro application related to the preparation of financial reports. The KRE Cell business actor has recorded transactions using the Lamikro application. The results have been achieved from the implementation of the first development of the KRE Cell financial position and profit and loss statements that have been compiled with the Lamikro Application. Although business actors do not come from accounting, they want to learn the use of applications in compiling financial reports for the reason that it is easier and faster. KRE Cell business actors have recorded transactions using the Lamikro Application. KRE Cell business actors understand promotion and marketplace using social media, namely using Facebook, Instagram.

Heart disease is biggest challenge for medical professionals. Modern life style made it an epidemic; according to a survey conducted by WHO heart attack is leading cause of death all over the world especially in the western world. It is surveyed that 23% of the death in US is due to Heart related disease [1]. It has been observed assistance is needed for helping medical professionals in detecting the chance of heart attack in the human. In recent times a lot of work related to providing an automated support system for predicting chance of Heart attack in human has been done. After advancement of computer science, researchers felt that they can help in some of the key interdisciplinary areas like medical science. Machine learning techniques are compared on the single data set which does not reflect true potential of any algorithms. They also suffer from some of the key anomalies such as accuracy and manual data set pre-processing. In this paper, we propose Deep Neural Network methods for creating an automated system for heart attack prediction. It is tested on multiple dataset to find out true potential and providing certainty in the accuracy. Method also promises to remove all the mentioned anomalies from the system like lack of accuracy and automated approach in pre- processing of the data set. In result analysis, it has been observed that prediction is much more efficient and minimum accuracy achieved through this proposed method is 87.64% on any of the data set taken under consideration.


This paper draws on data from an exploratory research project that was carried out at the Centre for Higher Education and Capabilities Research (CHECaR) at one South African university in 2012. I examine the experiences of one student, Jane1 who is disabled according to the university's categorisation of disability. She chose not to identify herself as such and did not declare her status to the university, even though students are encouraged to declare their disability/impairment status on the official application form. Although some students declare their status and thus are referred to the university's Disability Services Unit for Special Services, other students don't declare their status. Few studies in the Global North have looked at the reasons why some students choose not to declare their disability status. It is usually difficult to access the perspectives of those who choose not to declare. Theoretically, Jane's account provides some insight about the reasons why some students choose not to declare their disability status. Drawing on the identity concept, factors that influenced her decision not to declare, and the consequent effect on her experience of higher education (HE) are explored. The article uses the capabilities approach (CA) as espoused by Sen and Nussbaum, as a theory that foregrounds social justice issues in education. Using the CA's core concepts, the paper lucidly conceptualises disability and social justice, terms that are frequently but loosely used in both academia and policy. The CA helps in understanding identity and social justice issues and facilitates the understanding of the complexity, and interconnected processes.


A series of PdSn binary catalysts with varied molar ratios of Pd to Sn are synthesized on B and N dual-doped graphene supporting materials. The catalysts are characterized by X-ray diffraction (XRD) and Transmission electron microscopy (TEM). Formic acid electro-oxidation reaction is performed on these catalysts, and the results reveal that the optimal proportion of Pd:Sn is 3:1. X-ray photoelectron spectroscopy (XPS) measurements show that when compared with 3Pd1Sn/graphene, B and N co-doping into the graphene sheet can tune the electronic structure of graphene, favoring the formation of small-sized metallic nanoparticles with good dispersion. On the other hand, when compared with the monometallic counterparts, the incorporation of Sn can generate oxygenated species that help to remove the intermediates, exposing more active Pd sites. Moreover, the electrochemical tests illustrate that 3Pd1Sn/BN-G catalyst with a moderate amount of Sn exhibits the best catalytic activity and stability on formic acid electro-oxidation, owing to the synergistic effect of the Sn doping and the B, N co-doping graphene substrate.

Does the information age have a proletariat? You betcha sweet ass it does. If Marx is still remembered today, he is remembered as an economist, political theorist and philosopher. But his role as ethnographer of the British working class in the nineteenth century is often forgotten: the relevant and copius pages of capital are hardly referred to. But in the 1980s and 1990s, a different literate proletariat has emerged, with access to complex communication devices and the ability to write and disseminate the fine details of its own conditions of existence.

Along with other sources of information, archival materials and the data of Saratov local press of those years have been used in our work.


In response to the rapid spread of the novel coronavirus, SARS-CoV-2, the U.S. has largely delegated implementation of non-pharmaceutical interventions (NPIs) to local governments on the state and county level. This staggered implementation combined with the heterogeneity of the U.S. complicates quantification the effect of NPIs on the reproductive rate of SARS-CoV-2. We describe a data-driven approach to quantify the effect of NPIs that relies on county-level similarities to specialize a Bayesian hierarchical inference model based on observed fatalities. Using this approach, we estimate change in reproductive rate, Rt, due to implementation of NPIs in 1,417 U.S. counties. We estimate that as of May 28th, 2020 1,177 out of the considered 1,417 U.S. counties have reduced the reproductive rate of SARS-CoV-2 to below 1.0. The estimated effect of any individual NPI, however, is different across counties. Stay-at-home orders were estimated as the only effective NPI in metropolitan and urban counties, while advisory NPIs were estimated to be effective in more rural counties. The expected level of infection predicted by the model ranges from 0 to 28.7% and is far from herd immunity even in counties with advanced spread. Our results suggest that county characteristics are pertinent to re-opening decisions.


The effect of buffer conditions — varying in salt type, pH, and concentration – on the separation of 8‐aminonaphthalene‐1,3,6‐trisulfonic acid (ANTS)‐labeled monosaccharides and complex‐type carbohydrates was investigated. Different buffer systems for high and low electroosmotic flow conditions were chosen: a phosphate and a citriate background electrolyte, each at pH 2.5, a phosphate buffer, pH 9.0, and a borate buffer at pH 9.5. All buffer systems displayed differences in resolution and selectivity. Phosphate and borate buffer demonstrated the greatest selectivity changes for ANTS‐labeled carbohydrates. While separation in the phosphate system relies mainly on differences in the charge‐to‐mass‐ratio, additional selectivity can be achieved with borate complexation of glycoconjugates. The use of borate buffers improved monosaccharide separations whereas complex carbohydrates showed a loss in resolution. The citrate background electrolyte at low pH caused no significant changes in the separation performance. The pH 9.0 phosphate buffer showed a reversed migration order of the ANTS conjugates with a decreased resolution, compared to the pH 2.5 phosphate buffer, due to the strong electroosmotic flow generated under high pH conditions. An ovalbumin‐derived oligosaccharide library demonstrates the significance of buffer selectivity for complex carbohydrate separations. The separation in the acidic phosphate and the alkaline borate buffer generates a different pattern and only the combination of both buffer systems allows an appropriate assessment of sample complexity.

Belitung island is known as the place with hundreds of coffee shop/café and the people have the culture of coffee in their daily lives. The Belitung geopark was established in 2018 as a national geopark that has a community that develops geoproducts, and coffee is one of their geoproducts. The study examines the marketing of coffee as the geoproduct of Belitung island geopark and how coffee plays a role in the community's livelihood. The study method used was qualitative , where primary and secondary data were collected through desk study, field study, observations and interviews. Content analysis and descriptive analysis were conducted in the study. The result showed that coffee as a geoproduct of Belitung Island in terms of marketing has value, distribution of the product is still limited and coffee plays an important role in the community. In addition, SMEs are the main producer and marketer for coffee. The problems related with marketing coffee are in its product development and branding strategy, also the value chain needs to be upgraded. This study provides a baseline for future development of geoproducts in the island geopark of Belitung.


[Objective] To optimize intraoperative parameters of C-arm X-ray apparatus and to effectively reduce radiation exposures to operators and patients.[Methods] In human model stimulation surgery,parameters of dose area product(DAP) of 5 built-in fixed programs(P1-P5) were compared under continuous fluoroscopy,pulsed fluoroscopy and high contrast fluoroscopy modes.Pelvis(P2) image qualities in pulsed fluoroscopy and high-contrast perspective modes were evaluated in accordance with the image quality standards by Commission of the European Community(CEC).[Results] There were significant differences in the DAP values of the same program among three modes(P 0.01).The DAP values were lower in the pulsed fluoroscopy mode than in the continuous fluoroscopy mode and the high contrast fluoroscopy mode(P 0.01).There were significant differences in the DAP values under the same mode among different programs(P 0.01).The DAP value was found significantly higher in the lumbar spine(P3) program than in other programs(P 0.01).There was no significant difference in the image qualities between pulsed fluoroscopy and high-contrast perspective modes,but the DAP values were increased significantly(P 0.01).There were significant differences in the image qualities under pulsed fluoroscopy mode between P2 and limbs(P4) programs.[Conclusion] Correct and reasonable use of the parameters of C-arm X-ray apparatus can effectively reduce radiation damage to medical professionals and patients.


Pitch,furan,phenolic aldehyde and Epoxy based TiB2-C cathode composites were prepared in the mould pressing-baking process,and their corrosion resistance in [K3AlF6/Na3AlF6]-AlF3-Al2O3 melts was studied.The results show that no matter what kind of binder is used,TiB2-C cathode composites have the good wetting property by liquid aluminum.Pitch based TiB2-C cathode composite has the poor corrosion resistance,and its corrosion rate and penetration rate of alkali metals(K,Na) is 8.09 mm/a and 10.6 mm/h respectively.In contrast,phenolic aldehyde based TiB2-C cathode composite has the stronger corrosion resistance,and its corrosion rate and penetration rate of alkali metal is 3.05 mm/a and 4.72 mm/h,respectively,which decreases by 62.3% and 55.5%.Compared with pitch,resin based TiB2-C cathode composites have stronger resistance ability to penetration of alkali metals.Among them,phenolic aldehyde based TiB2-C cathode composite exhibits the strongest resistance ability to penetration of alkali metals.The use of resin as adhesive can improve the corrosion resistance of TiB2-C cathode composites to some extent.


The release of translational energy in the dissociation of energy-selected CH+4 and CD+4 ions is measured by a photoelectron–photoion coincidence experiment. Loss of H and D, respectively, are the principal reactions observed; detailed kinetic energy distributions accompanying the formation of CH+3 and CD+3 are obtained. The surprisal content of these distributions is found to be identical at all ionization energies observed and for both isotopes. A statistical model of the dissociations is considered to be appropriate and a number of calculations are performed. It is found that the use of the Langevin model to describe the effects of the centrifugal barrier to dissociation does not give exact quantitative agreement with the experimental results and this deficiency is examined.

The characteristic pyrogram was obtained under the conditions of low laser intensity and addition of sodium borohydride.


The member of CPC is a pioneer who has communist consciousness,which is decided by the guideline of Marxism.As a solider who has communist consciousness,he must be a committed Marxist.At present,for the update of the body of Party and a high proportion of communists haven't accepted the education of basic principle of Marxist,the ideological struggle greatly attacks their thoughts,and thus to emphasize this topic has particular and important significance.A committed Marxist must have a firm faith on Marxism,constantly adhere to the leadership of Marxism,study the classical Marxist works hard,and use basic Marxist principles.In our study,we combine the classical Marxist works with Deng Xiaoping theory,Three Represents theory and scientific outlook on development,and persist in the combination of Marxist universal truth and practice and the principle of integrating theory with practice.


The promising methodology of the "Statistical Learning Theory" for the estimation of multimodal distribution is thoroughly studied. The "tail" is estimated through Hill's, UH and moment methods. The threshold value is determined by nonparametric bootstrap and the minimum mean square error criterion. Further, the "body" is estimated by the nonparametric structural risk minimization method of the empirical distribution function under the regression set-up. As an illustration, rainfall data for the meteorological subdivision of Orissa, India during the period 1871–2006 are used. It is shown that Hill's method has performed the best for tail density. Finally, the combined estimated "body" and "tail" of the multimodal distribution is shown to capture the multimodality present in the data.

The prepared beverage is sweet and sour, rich in nutrients, special in flavor, and has effects of promoting the secretion of saliva or body fluid, clearing heat and alleviating hangover, lubricating the intestines and promoting diuresis, resisting tumors, resisting ageing, soothing the nerves and relieving the restlessness, and helping digestion and losing weight.


Summary Data from a VTEM™ airborne electromagnetic survey over resistive terrain is examined. Forward modelling and analysis of high-altitude lines shows that the amplitudes of random noise, bucking error, processing corrections and geological signals can be large compared to the geological signal in the resistive terrain. The negative impacts of the low geological signal to noise ratio on conductivity estimates generated by layered-earth inversion and conductivity transformations are demonstrated. The reader is alerted to the degree of uncertainty and non-uniqueness that is inherent in conductivity estimates generated from similar datasets.


Second stage larvae of three Oestridae species, Oestrus ovis (Linnaeus, 1758), Cephalopina titillator (Clark, 1816) and Rhinoestrus usbekistanicus (Gan, 1947) were described in detail using scanning electron microscopy. Their morphological features were compared. O. ovis and R. usbekistanicus show several common characteristics which make them quite different from C. titillator. These observations seem to validate the cladogram of adult Oestridae genus established by Papavero (1977).


EDM technology is still facing a big bottleneck problem unsolved: low molten material removal rate, resulting in low machining speed and poor surface quality. To improve the material removal amount in each discharge process of EDM, the composite pulse current waveforms were proposed. The single pulse discharge experiments demonstrate that under the same discharge energy, the material removal volume in the discharge with the end composite pulse could be twice as high as that with the square pulse. Furthermore, due to high molten material removal rate of the end composite pulse, the thickness of the recast layer generated in the discharge with the end composite pulse was much thinner than that with the square pulse under the same discharge energy. The MD simulation results also reveal that in the discharge with the end composite pulse, the basic current mainly melted the material to form a larger molten pool, then, the inrush current, which has higher energy density and higher material removal motivity, could remove the molten pool material largely. Thus, the end composite pulse can improve the molten material removal rate and decrease the recast layer. Finally, EDM milling experiments show that higher average material removal volume in each discharge process of EDM milling with the end composite pulse was the main reason for higher material removal rate (MRR) in EDM milling with the end composite pulse. In addition, the relative tool wear ratio (RTWR) in EDM milling with the end composite pulse can be approximately equal to or slightly lower than that with the square pulse at a high material removal rate in EDM milling, which shows a great application potential of the end composite pulse in EDM.

This paper introduces scraped online data to study price-stickiness in developing countries. Scraped data constitute a unique source of price information in terms of detail, sampling frequency, and country availability, allowing simultaneous cross-country analyses in a variety of macroeconomic settings. Using a dataset with more than 21 million prices in four Latin American countries during a time of high inflation, from October 2007 to October 2008, I present stylized sticky-price facts and provide four main empirical results. First, countries with more frequent price changes do not have higher inflation rates. Second, there is evidence of menu costs in the bimodal distribution of the size of price changes. Third, hazard functions tend to be upward sloping, consistent with state-dependent pricing. Fourth, there is strong daily price synchronization within narrow categories, or aisles, which suggests that strategic complementarities can play an important role in price-setting decisions.


Jaccard has been the choice similarity metric in ecology and forensic psychology for comparison of sites or offences, by species or behaviour. This paper applies a more powerful hierarchical measure - taxonomic similarity (s), recently developed in marine ecology - to the task of behaviourally linking serial crime. Forensic case linkage attempts to identify behaviourally similar offences committed by the same unknown perpetrator (called linked offences). s considers progressively higher-level taxa, such that two sites show some similarity even without shared species. We apply this index by analysing 55 specific offence behaviours classified hierarchically. The behaviours are taken from 16 sexual offences by seven juveniles where each offender committed two or more offences. We demonstrate that both Jaccard and s show linked offences to be significantly more similar than unlinked offences. With up to 20% of the specific behaviours removed in simulations, s is equally or more effective at distinguishing linked offences than where Jaccard uses a full data set. Moreover, s retains significant difference between linked and unlinked pairs, with up to 50% of the specific behaviours removed. As police decision-making often depends upon incomplete data, s has clear advantages and its application may extend to other crime types. Copyright © 2007 John Wiley & Sons, Ltd.


Abstract Background Mycobacterium abscessus is a common rapid growing mycobacteria (RGM). It causes chronic nodular or cavitary lung disease in adults with bronchiectasis or cystic fibrosis, skin and soft tissue infection following penetrating injury or an unsterile skin procedure. It was also a pathogen of disseminated infection in patients with anti-interferon-gamma autoantibodies. The 2018 clinical and laboratory standards institute (CLSI) guideline suggested that amikacin, cefoxitin, ciprofloxacin, clarithromycin, doxycycline, imipenem, linezolid, meropenem, moxifloxacin, trimethoprim-sulfamethoxazole, tigecycline and tobramycin should be tested against RGM. We aimed to review the antimicrobial susceptibility of this organism in our hospital. Methods We performed a retrospective descriptive review of the minimal inhibitory concentration (MIC) of clinical isolates of M. abscessus from 2013 to 2018. Results We found 267 isolates of M. abscessus. Eighty-four isolates were tested for MICs. Of these, 4 isolates were excluded due to duplication. The remaining 80 isolates were included for analysis. The susceptibility results were as follows. Antimicrobial agents (N) Susceptible (%) Intermediate (%) Resistant (%) Amikacin (80) 86.25 7.50 6.25 Cefoxitin (80) 3.75 31.25 65 Ciprofloxacin (79) 1.27 3.80 94.93 Clarithromycin (80) 97.50 0 2.50 Doxycycline (32) 0 9.38 90.62 Imipenem (80) 0 15.00 85.00 Linezolid (26) 50.00 23.08 26.92 Moxifloxacin (26) 0 7.69 92.31 Trimethoprim-sulfamethoxazole (80) 2.5 0 97.5 Tobramycin (24) 4.17 20.83 75 Conclusion To our knowledge, this is the largest report of susceptibility pattern of M. abscessus in Thailand. MICs of cefoxitin and imipenem, which are the recommended intravenous antimicrobials, were high. Most isolates also demonstrated high MICs of doxycycline, linezolid, trimethoprim-sulfamethoxazole, tobramycin, ciprofloxacin and moxifloxacin. In contrast, most of MICs of amikacin and clarithromycin were in susceptible range. These findings may be used to guide the treatment regimen although clinical outcomes of each drug are still to be investigated. Disclosures All Authors: No reported disclosures.


Unheated peels were sufficiently cured to permit their removal from the trench in 30 to 40 hours when ground temperature was near 20°C and air temperature somewhat higher. They remained quite fragile for more than a week, however. Those that were heated for 2.5 hours could, by contrast, be removed after cooling 30 to 40 minutes and were sufficiently durable to permit sawing and shaking the following day. Although cumbersome (a lot of equipment is needed), this technique reliably produces peels with good illustrative qualities. Characteristics of this method that make it superior for some peel-making situations are 1) the lithified slabs are strong and self-supporting; 2) moisture does not inhibit the process; 3) structures are visually enhanced by high relief on the peel face; 4) large vertical sections of coarse-grained sediments can be preserved; 5) peels can be removed from trench in 3 hours; and 6) very large trench faces can be impregnated in sections. We thank B. D. Manning, Jr., for access to the Congaree point bar over private roads, and South Carolina Electric and Gas Company for its cooperation in maintaining a low river stage at a time critical to our sampling. We especially thank Danny Dorn for operating his earthmoving equipment in such a careful, patient manner while assisting our trenching operation on the Congaree point bar.


INTRODUCTION: The use of ketamine as a sedative agent has increased dramatically in patients who are mechanically ventilated (MV) due to COVID-19 in intensive care units (ICU). Ketamine primarily acts as an NMDA receptor antagonist that blocks the excitatory effects of glutamate. In comparison to other sedatives, ketamine has a more favorable hemodynamic profile and does not produce significant respiratory depression. The study sought to analyze the impact of initiating ketamine continuous infusions for sedation in MV patients on co-sedation dosing. METHOD(S): This was a single-center, retrospective, observational study. All MV patients admitted to the medical intensive care unit from October 1st, 2019 to October 31st, 2021 who received ketamine continuous infusions for sedation for more than 12 hours were be eligible for inclusion. RESULT(S): Of 167 patients identified, 76 (45.5%) patients were included. The average ketamine infusion rate was 0.65 mg/kg/hr and average duration was 3.9 days. At the start of ketamine, 74 patients were on fentanyl, 27 (36.5%) of those patients were successfully weaned off fentanyl (10.8%) or had a decrease in infusion rate (25.7%). A total of 47 patients were on propofol, 39 (83%) patients were successfully weaned off propofol (55.3%) or had a decrease in infusion rate (25.7%). Seventeen patients were on midazolam infusions, of those, 12 (70.6%) patients were successfully weaned off (52.9%) or had a decrease in rate (17.6%). There were 15 patients on dexmedetomidine, 6 (40%) patients were successfully weaned off (20%) or had a decrease in infusion rate (20%). At the start of ketamine, 71 patients were on norepinephrine + vasopressin + epinephrine. Of the 71 patients, 48 (67.6%) were able to wean off vasoactive agents or had a decrease in rate. Twelve patients had documented emergence reactions or adverse reactions during infusion. CONCLUSION(S): Ketamine continuous infusion as an adjunct analgosedative agent resulted in successful weans off co-sedative agents or in decreased infusion rates. It was particularly impactful on propofol and midazolam continuous infusions as more than 50% of patients on these two agents were successfully weaned off.


Objective
To explore hypertension patients' acceptability with the remote management model, and to provide a basis for clinical application in the future.

Methods
Totally 10 patients who received remote management between June and September 2016 were selected, and received unstructured interviews based on the technology acceptance model (TAM) with the phenomenological method in qualitative studies. And the data thus collected were analyzed and organized with the Colaizzi Seven-Step Method to find main themes.

Results
Totally 3 themes were found according to TAM, including perceived ease of use (the management platform was easy for use according to patients) , perceived usefulness (patients better understood their own blood pressure, changed their habits of blood pressure monitoring and unhealthy lifestyle, improved treatment efficiency, and saved time costs) , and intention of use (the participation of medical and nursing staffs could directly affect patients' intention of use, and patients had different opinions on expenses, believing that it was more meaningful to conduct remote management in short time and in particular cases) .

Conclusions
Patients show a high acceptability with the remote management model, and in clinical application, further research is needed to tackle real difficulties and ensure the sustainable development of the model.

Key words:

A density functional theory is applied to study wetting behaviors of binary associating mixtures, which are described by the statistical associating fluid theory of Wertheim. When the associating interaction is strong, the phase behavior of the binary associating mixture falls into the type-VI mixtures of the classification scheme of van Konynenburg and Scott. There are two types of closed-loop phase behaviors for the type-VI mixture. That is, a closed-loop phase diagram for vapor–liquid–liquid coexistence (along its triple line) at low pressures and the other one for liquid–liquid coexistence at a relatively high pressure. In this study, the wetting behavior of the lower liquid phase at the surface of the upper liquid phase is carefully examined for both vapor–liquid–liquid coexistence and liquid–liquid coexistence regimes. In the latter regime, a third inert air phase is introduced since wetting behavior always involves three phases. For both regimes the binary associating mixture exhibits a sequence of...


The concept of an emerging city, coined by the IDB, has allowed this institution to promote the evaluation of sustainability and quality of life through 120 indicators that measure: Climate Change and Environment; Integral Urban Development; and Fiscal and Governance area. The purpose of this article, in its first phase, is to propose the Balance Scorecard as a method to carry out the evaluation of these indicators, plus 32 tourism indicators of the researcher Ledger Brenner. The city of Cancun has a population of almost one million inhabitants, hosts almost 5 million tourists a year, and shows a significant economic and urban growth. This city requires a sustainable growth that can be evaluated so that the actors that interact in its territory: citizens, authorities, tourist economic agents and tourists know it. This research project in its second phase aims to measure the 152 interconnected indicators to calculate an index of sustainability and quality of life that can make its results known in an open access platform on the web.

Thus, the testing efficiency and reliability are optimized, thereby providing a good method for batch detection of frequency hopping of the quartz crystal oscillator.


The article analyzes the features of the preparation and appointment of forensic examination of vehicles, procedural and tactical requirements for this examination. The vehicle is a special object of forensics, which imposes certain restrictions on its preparation for examination.
Specific requirements for the tactics of investigative actions with this object are intended to ensure the legality and admissibility of evidence for criminal proceedings. The vehicle is also an object for conducting expert studies of various types. The issue of changing the identification numbers (body, engine), determining the year of manufacture, replacing the data carriers about the car (number and code plates, etc.) are resolved by means of traceability. To solve the issue of replacing the body number by replacing the panel with a number plate, a complex forensic chemical (paintwork research) and trace evidence examination are appointed.
The issue of re-equipment of the vehicle is solved by complex trace evidence and commodity expertise, etc. The complexity of the study of the vehicle and the accompanying documents requires the appointment of directly comprehensive examinations of various types.
In the investigation of unlawful acts related to the illegal movement of vehicles across the customs border of Ukraine, auto-merchandising and transport- merchandising examinations can also be carried out to solve the problems associated with determining the market value of wheeled vehicles, their components, as well as the amount of the cost of material losses caused to the owner or to the owner of wheeled vehicles, their components due to damage to the latter. The indicated examinations are quite often appointed in conjunction with the trace evidence examination.
The fulfillment of certain procedural requirements is designed to ensure the legality and admissibility of evidence obtained in the course of investigative actions and the results of forensic examinations conducted by them.


A hydrolyzable polyrotaxane composed of an ester-containing poly(ethylene glycol) chain and α-cyclodextrins showed gradual degradation into its water-soluble components in aqueous conditions, based on the dissociation of the polyrotaxane triggered by the hydrolysis of the ester groups.


In order to reduce the power consumption of impeller blower and increase its blowing distance, effects of impeller's rotational speeds and blade's slanted angles on the power consumption and blowing distance of impeller blower were studied on an impeller blower test bench, which was developed as the test machine for studying blowing performance of impeller blowers. Results suggested that when impeller's external diameter was Ф700mm, its optimal rotational speed was within a range between 800 and 1100r/min. Radial blade consumed minimum power while blade with a backward slanted angle of 10° could achieved the longest blowing distance. This study could provide a basis for parameter optimization for impeller blowers.
