Application Of Whale Optimization Algorithm For Text Document Clustering

Abstract In order to efficiently navigate, summarize, and organize information, rapid and high-performance document clustering algorithm plays a critical role. The researchers have revealed that the partitional clustering techniques are better suited to cluster the large document corpus. However, the most often used partitional clustering approach, the K-means algorithm, can only yield a local optimum solution. A whale optimization algorithm (WOA) based document clustering technique is proposed in this work. In contrast to the K-means method's confined search, the WOA clustering algorithm does a global search throughout the whole solution space. Experimental analysis is performed on four distinct text document databases using the WOA and K-means algorithms. The databases include between 204 and 900 documents and around 5000 to 7500 words. The findings demonstrate that compared to the K-means method, the WOA algorithm produces more compact clustering results.
A Fluid Generalization of Membranes

In a certain sense a perfect fluid is a generalization of a point particle. This leads to the question as to what is the corresponding generalization for extended objects. The lagrangian formulation of a perfect fluid is much generalized and this has as a particular example a fluid which is a classical generalization of a membrane, however there is as yet no indication of any relationship between their quantum theories.
Advanced Uncertainty Quantification and Novelty Detection for Random Forest Models

In practical applications, model accuracy alone is insufficient; quantifying model uncertainty is crucial, particularly in mission-critical scenarios involving life, money, or reputation. In this paper, we propose a novel method called MACAU (Model-based AleatoriC and epistemic uncertainty Uantification) and implement it in the LightGBM gradient-boosting framework. MACAU enables the quantification of both aleatoric and epistemic uncertainties in Random Forest (RF). Additionally, MACAU offers enhanced noveltydetection capabilities, particularly valuable for identifying out-of-distribution (OOD) samples. We compare MACAU with other RF- or gradient boosted trees-based methods, including RF-native between-variance, quantile regression, inductive conformal prediction, exogeneous model for uncertainty estimation using the Gaussian negative log-likelihood method, Natural Gradient Boosting, and CatBoost. Our evaluation is conducted on both synthetic and real-world regression cases. The results demonstrate the effectiveness of MACAU in quantifying model uncertainty, as measured by the Continuous Ranked Probability Score, as well as detecting OOD samples, as measured by the ROCAUC.
The Rodney L . White Center for Financial Research The Cost of Trend Chasing and the Illusion of Momentum Profits

There is a large and growing literature documenting the relation between ex ante observable variables and stock returns. Importantly, much of the evidence on the relation between returns and observable variables like market capitalization, the ratio of price/book, and prior price change has been portrayed in the context of returns to simulated portfolio strategies. Often missing in these analyses is the distinction between realizable returns (i.e., the returns portfolio managers can realistically achieve in practice) and returns to simulated strategies. There is ample evidence that size and value strategies can be successfully implemented in practice; that is not the case for momentum strategies. This paper documents the costs of implementing actual momentum strategies. I examine the trade behavior, and the costs of those trades, for three distinct investor styles (momentum, fundamental/value, and diversified/index) for 33 institutional investment managers executing trades in the U.S. and 36 other equity markets worldwide in both developed and emerging economies. The results show: (1) that momentum traders do indeed condition their trades on prior price movements; and (2) that costs for trades that are made conditional on prior market returns are significantly greater than for unconditional costs, especially for momentum traders. The evidence that we report on the actual costs of momentum-based trades indicates that the returns reported in previous studies of simulated momentum strategies are not sufficient to cover the costs of implementing those strategies.
SERUM AMH AS AN INDICATOR OF OVARIAN DYSREGULATION IN PCOS PATIENTS

Background: Introduction: Endocrine disorders are affecting commonly the reproductive age females. Most common of them is Polycystic ovary syndrome (PCOS). It affects roughly around 4%–18% of females of reproductive potential. Anti-Mullerian hormone is produced by granulosa cells of antral follicles of ovary. Women who are diagnosed with PCOS usually have increased amount of Anti mullerian hormone as compared to women without polycystic ovarian syndrome. Objectives: To estimate level of S.AMH in PCOS patient. To access the efficacy of S. AMH for prediction of ovarian dysregulation in PCOS patient. Material & Methods: The study was an observational analytical study conducted on 100 female patients who attended the Gynecology OPD and those who were admitted in the Gynecology ward of Kamla Nehru Memorial Hospital &Swaroop Rani Nehru Hospital both were affiliated to Motilal Nehru Medical College, Prayagraj, UP, India for the duration of 1 year starting from August 2018. S.AMH levels were measured using a highly sensitive Access AMH kit which used a twostep competitive binding enzymatic immonoassay. Statistical analysis was done using Chi-square test. Results: Maximum cases had raised Serum AMH(15.72±3.42ng/ml) i.e. 60 (60%) and 40 (40%) had normal Serum AMH (6.089±1.75ng/ml). (p =0.0001 i.e significant). Conclusion: Our study concludes that women with PCOS have elevated S.AMH levels (60%) as compared to normal population. Thus S.AMH seems to be reliable marker for ovarian dysregulation in Polycystic ovarian syndrome.
A Novel Rough Set Based Congestion Control Technique for the Effective Routing in WSN

: Congestion control is deemed to be one in all the foremost vital problem in Wireless sensor Networks (WSNs) that is consist of resource constraint specification and also the range of deployed nodes. Congestion is caused by several factors such as node buffer overflow, channel contention, packet collision, transmission, transmission rate and many more. Congestion results packet loss or the blocking of new connections, queuing delay in networks. The proposed Rough Set based Congestion Control (RSCC) system that enables the section of stable routes to transmit packets that manage traffic condition during high congestion period in wireless sensor networks which achieves Rough Set Creation Algorithm (RSCA) and routing model. The Rough Set Creation Algorithm (RSCA) accepts the inputs from training dataset and produces the reduced dataset. The routing model directs the alternative directions while congestion occurs based on traffic rate in the networks. The simulation result shows that the performance of our scheme is better in terms of packet delivery rate, number of packets drop and delay.
Review: Identity and the Natural Environment: The Psychological Significance of Nature

The Clayton-Opotow volume is a useful primer on identity and the environment. Since both “identity” and “nature” are slippery terms, the introduction sets out their parameters. Personal identity emerges in a social context that includes interpersonal and group memberships. Thus identity has a cultural and social aspect. The experience of nature is rooted in a social and cultural experience. Environmental identity can be conceptualized as occurring along a continuum. Identity and the Natural Environment is divided into sections based on the degree of social influence on environmental identity, ranging from the minimal to the strong.
The photonic nanowire: an emerging platform for highly efficient single-photon sources for quantum information applications

Efficient coupling between a localized quantum emitter and a well defined optical channel represents a powerful route to realize single-photon sources and spin-photon interfaces. The tailored fiber-like photonic nanowire embedding a single quantum dot has recently demonstrated an appealing potential. However, the device requires a delicate, sharp needle-like taper with performance sensitive to minute geometrical details. To overcome this limitation we demonstrate the photonic trumpet, exploiting an opposite tapering strategy. The trumpet features a strongly Gaussian far-field emission. A first implementation of this strategy has lead to an ultra-bright single-photon source with a first-lens external efficiency of 0.75 ± 0.1 and a predicted coupling to a Gaussian beam of 0.61 ± 0.08.
How has hospital consolidation affected the price and quality of hospital care ?

The 1990s witnessed a wave of hospital consolidation, dramatically increasing the number of people living in highly concentrated hospital markets. The balance of evidence shows that consolidation: > Raised hospital prices by at least fi ve percent and perhaps much more. > Produced modest cost savings for merging hospitals. Hospitals merging operations (and not just ownership) experienced the most savings. > Possibly resulted in lower quality. How did the hospital market change in the 1990s? g A wave of hospital mergers and acquisitions in the 1990s transformed the inpatient hospital market. By the mid-1990s hospital merger and acquisition activity was nine times its level at the start of the decade (Figure 1). By 2003, almost ninety percent of people living in the nation's larger MSAs faced highly concentrated markets. Stakeholders and policy-makers have raised concerns about this consolidation trend, pointing to potential impacts on health care costs and quality. This brief analyzes the drivers of consolidation and evidence on how it has affected hospital prices, cost and quality. g The hospital consolidation wave was national in scope, but was most striking in the South. In 2003, as a decade earlier, the South was the most consolidated region with the highest percentage of merging hospitals. The percent rise in consolidation was greatest in the East, however, where the concentration level (HHI) increased 54 percent from 1990 to 2003.
Discovering Frequent Itemset From Long Transactions Using OMIT Algorithm In Big Data

The discovery of the frequent itemsets from large datasets and long transaction dataset in big data is a tedious task and it requires enormous amount of power and memory to drive and unearth the underlying patterns. The idea of utilizing the map reduce will considerably reduce the complexity of huge number of candidate generation and more importantly decreases the execution time and memory footprints but in some data sets with very long transactions the computation overhead becomes a major head ache and this paper proposes a new algorithm named as OMIT (omitted items in transaction to find frequent itemset) to evade the overheads using omitted items to discover the frequent itemsets at a rapid pace with minimum memory usage and with very less candidate generation. The proposed algorithm was compared with few existing algorithms and from the experimental results the proposed algorithm outscored the existing algorithm by a good margin.
Effects of Blended (NPSB) and Urea Fertilizer Rate on Yield and Yield Components of Wheat in Ultisols of Liben Jawi District, Oromia, Ethiopia

: Wheat production is achieved with under optimum application of recommended fertilizer and grain yield trends of newly released wheat varieties are low. This in view a field experiment was carried out on farmers field in 2018 and 2019 cropping season in Ultisol of Liben Jawi district to determine the effect of blended NPSB and urea fertilizer rate on growth, yield and yield components of recently release wheat variety (Wane). Three rates of urea (150, 250 and 350 kg N ha ) and four rates of blended NPSB (150, 200, 250 and 300 kg NPSB 1 ha ) were purposely combined to 12 treatments and tested with negative control and recommended (64/20 kg 1 NP ha ) was laid out in randomized complete block design with three replications. All growth yield and yield 1 components of wheat were significantly affected with application of urea and blended NPSB fertilizer rates indicating the importance applying optimum fertilizer rate for better yield of wheat. Significantly higher (3919 kg ha ), grain yield in farm one with application of 250/150 kg urea/NPSB ha , (5747, 5349 and 4857 kg 1
Does dynamically modelled leaf area improve predictions of land surface water and carbon fluxes? - Insights into dynamic vegetation modules

Land-surface models represent exchange processes between soil and atmosphere via the surface by coupling water, energy and carbon fluxes. As it strongly mediates the link between these cycles and, vegetation is an important component of land-surface models. In doing so, some of these models include modules for vegetation dynamics which allow adaptation of vegetation biomass, especially leaf area index, to environmental conditions. Here, we conducted a model-data comparison to investigate whether and how vegetation dynamics in the models improves the representation of vegetation processes and 5 related surface fluxes in two specific models ECLand and Noah-MP in contrast to using prescribed values from look-up tables or satellite-based products. We compare model results with stations from the FLUXNET 2015 dataset covering a range in climate and vegetation types, the MODIS leaf area product, and use more detailed information from the TERENO site “Hohes Holz". With the current implementation, switching vegetation dynamics on did not enhance representativeness of e.g. leaf area index and net ecosystem exchange in ECLand, while Noah-MP improved it only for some sites. The representation of energy 10 fluxes and soil moisture was almost unaffected for both models. Interestingly, for both models, the performance regarding vegetation-and hydrology-related variables was unrelated, such that the weak performance regarding e.g. leaf area index did not detoriate the performance regarding e.g. latent heat flux. One reason, we showed here, might be that implemented ecosystem processes diverge from the observations in their seasonal patterns and variability. Noah-MP includes a seasonal hysteresis of the relationship between leaf area index and gross primary production that cannot be found in observations. The same relationship 15 is represented by a strong linear response in ECLand which substantially underestimates
Gemological Investigation of a New Type of Russian Hydrothermal Synthetic Emerald

Tairus, in Novosibirsk, has produced yet another new type ofRussian hydrothermal synthetic emerald, now being marketed in Bangkok. Examination of eight fac eted samples revealed that, with the exception of certain characteristic inclusions, the basic gemological properties shown by this new synthetic are essentially the same as those encountered in other hydrothermally grown synthetic emeralds and some natural emeralds. If the characteristic inclusions are not present, distinctive spectral characteristics in both the midand near-infrared regions ofthe spectrum will serve to separate these synthetic emeralds from their natural counterparts.
Fault interactions and triggering during the 10 January 2012 Mw 7.2 Sumatra earthquake

The 10 January 2012 Mw 7.2 Sumatra earthquake in the Wharton basin occurred 3 months before the great Mw 8.6 and Mw 8.2 earthquakes in the same region, which had complex ruptures and are the largest strike‐slip earthquakes ever recorded. Teleseismic P wave back projection of the Mw 7.2 earthquake images a unilateral rupture lasting ∼40 s without observable frequency dependency (low frequency, 0.05–0.3 Hz, high frequency, 0.3–1 Hz). In addition to radiation bursts during the Mw 7.2 main shock, coherent energy releases from 50 to 75 s and from 100 to 125 s are observed about 143 km northeast of the main shock rupture and landward of the trench. Analysis of globally recorded P waves, in both 0.02–0.05 Hz velocity records and 1–5 Hz stacked envelope functions, confirms the presence of coherent sources during the time windows. The observed energy bursts are likely to be large early aftershocks occurring on or near the subduction interface. Both dynamic and static triggering could have induced these early aftershocks, as they initiated after the surface wave passed by, and the Coulomb stress perturbations from the Mw 7.2 main shock promote earthquakes in the observed locations. The earthquake sequence is a clear example of a seaward‐intraplate strike‐slip earthquake triggering landward‐intraplate earthquakes in the same region, in contrast to previously reported normal‐reverse or reverse‐normal interactions at subduction zones.
A comparative analysis of in situ measurements of high-altitude cirrus in the tropics

Abstract. We analyze cirrus cloud measurements from two dual-instrument cloud spectrometers, two hygrometers and a backscattersonde with the goal of connecting cirrus optical parameters usually accessible by remote sensing with microphysical size-resolved and bulk properties accessible in situ. Specifically, we compare the particle backscattering coefficient and depolarization ratio to the particle size distribution, effective and mean radius, surface area density, particle aspherical fraction, and ice water content. Data were acquired by instruments on board the M55 Geophysica research aircraft in July and August 2017 during the Asian Monsoon campaign based in Kathmandu, Nepal, in the framework of the StratoClim (Stratospheric and upper tropospheric processes for better climate predictions) project. Cirrus clouds have been observed over the Himalayan region between 10 km and the tropopause, situated at 17–18 km. The observed particle number densities varied between 10 and 10−4 cm−3 in the dimensional range from 1.5 to 468.5 µm in radius. Correspondingly, backscatter ratios from 1.1 up to 50 have been observed. Optical-scattering theory has been used to compare the backscattering coefficients computed from the measured particle size distribution with those directly observed by the backscattersonde. The aspect ratio of the particles, modeled as spheroids for the T-matrix approach, was left as a free parameter to match the calculations to the optical measures. The computed backscattering coefficient can be brought into good agreement with the observed one, but the match between simulated and measured depolarization ratios is insufficient. Relationships between ice particle concentration, mean and effective radius, surface area density, and ice water content with the measured backscattering coefficient are investigated for an estimate of the bulk microphysical parameters of cirrus clouds from remote sensing lidar data. The comparison between particle depolarization and aspherical fraction as measured by one of the cloud spectrometers equipped with a detector for polarization represents a novelty since it was the first time the two instruments were operated simultaneously on an aircraft. The analysis shows the difficulty of establishing an univocal link between depolarization values and the presence and amount of aspherical scatterers. This suggests the need for further investigation that could take into consideration not only the fraction of aspheric particles but also their predominant morphology.
