LaDEP: A large database of English pseudo-compounds
Authors: Auch Leah , Pérez Cruz Karen , Gagné Christina L. , Spalding Thomas L.
Published: July 2023

The Large Database of English Pseudo-compounds (LaDEP) contains nearly 7500 English words which mimic, but do not truly possess, a compound morphemic structure. These pseudo-compounds can be parsed into two free morpheme constituents (e.g., car-pet), but neither constituent functions as a morpheme within the overall word structure. The items were manually coded as pseudo-compounds, further coded for features related to their morphological structure (e.g., presence of multiple affixes, as in ruler-ship), and summarized using common psycholinguistic variables (e.g., length, frequency). This paper also presents an example analysis comparing the lexical decision response times between compound words, pseudo-compound words, and monomorphemic words. Pseudo-compounds and monomorphemic words did not differ in response time, and both groups had slower response times than compound words. This analysis replicates the facilitatory effect of compound constituents during lexical processing, and demonstrates the need to emphasize the pseudo-constituent structure of pseudo-compounds to parse their effects. Further applications of LaDEP include both psycholinguistic studies investigating the nature of human word processing or production and educational or clinical settings evaluating the impact of linguistic features on language learning and impairments. Overall, the items within LaDEP provide a varied and representative sample of the population of English pseudo-compounds which may be used to facilitate further research related to morphological decomposition, lexical access, meaning construction, orthographical influences, and much more.

CGScholar
Authors: Kline Sonia
Published: July 2023

Technology is pedagogically neutral—it may change everything, or it may change nothing–it is the pedagogy that makes the difference. The challenge then for new technologies is to disrupt traditional paradigms of teaching, and to promote an entirely different kind of pedagogy. In development since 2009, CGScholar, a cloud-based writing and assessment ecosystem responds to this challenge. This article discusses the theoretical basis of CGScholar, reflexive pedagogy, which is embedded into the design of the environment around seven key principles of learning and assessment: ubiquitous learning; active knowledge making; multimodal meaning; recursive feedback; collaborative intelligence; metacognition; and differentiated learning. Also articulated are the components of the learning ecosystem and the ways that the various applications of CGScholar bring these principles to life. Empirical studies conducted on CGScholar are reported and future developments are described.
Loss of aquaporin-1 expression is associated with worse clinical outcomes in clear cell renal cell carcinoma: an immunohistochemical study
Authors: Lee Seokhyeon , Kim Bohyun , Jung Minsun , Moon Kyung Chul
Published: July 2023

Background: Aquaporin (AQP) expression has been investigated in various malignant neoplasms, and the overexpression of AQP is related to poor prognosis in some malignancies. However, the expression of AQP protein in clear cell renal cell carcinoma (ccRCC) has not been extensively investigated by immunohistochemistry with large sample size.Methods: We evaluated the AQP expression in 827 ccRCC with immunohistochemical staining in tissue microarray blocks and classified the cases into two categories, high and low expression.Results: High expression of aquaporin-1 (AQP1) was found in 320 cases (38.7%), but aquaporin-3 was not expressed in ccRCC. High AQP1 expression was significantly related to younger age, low TNM stage, low World Health Organization/International Society of Urologic Pathology nuclear grade, and absence of distant metastasis. Furthermore, high AQP1 expression was also significantly associated with longer overall survival (OS; p<.001) and progression-specific survival (PFS; p<.001) and was an independent predictor of OS and PFS in ccRCC.Conclusions: Our study revealed the prognostic significance of AQP1 protein expression in ccRCC. These findings could be applied to predict the prognosis of ccRCC.
Reevaluating diagnostic categories and associated malignancy risks in thyroid core needle biopsy
Authors: Jung Chan Kwon
Published: July 2023

As the application of core needle biopsy (CNB) in evaluating thyroid nodules rises in clinical practice, the 2023 Korean Thyroid Association Management Guidelines for Patients with Thyroid Nodules have officially recognized its value for the first time. CNB procures tissue samples preserving both histologic structure and cytologic detail, thereby supplying substantial material for an accurate diagnosis and reducing the necessity for repeated biopsies or subsequent surgical interventions. The current review introduces the risk of malignancy within distinct diagnostic categories, emphasizing the implications of noninvasive follicular thyroid neoplasm with papillary-like nuclear features on these malignancy risks. Prior research has indicated diagnostic challenges associated with follicular-patterned lesions, resulting in notable variation within indeterminate diagnostic categories. The utilization of mutation-specific immunostaining in CNB enhances the accuracy of lesion classification. This review underlines the essential role of a multidisciplinary approach in diagnosing follicular-patterned lesions and the potential of mutation-specific immunostaining to strengthen diagnostic consensus and inform patient management decisions.

Modifying polymeric membranes using nanofiller is a promising method to enhance gas permeability and selectivity performance. This work used two types of ZIF-8 functionalized-2D nanofillers to fabricate polyethersulfone mixed matrix membranes. The rGO/ZIF-8 and MoS2/ZIF-8 nanofillers were first synthesised and characterised using FTIR and XRD. Then, 10 wt% of each nanofillers was added to the PES solution. TGA analysis indicates that MMMs containing rGO/ZIF-8 and MoS2 /ZIF-8 exhibit improved thermal stability. No additional peaks in FTIR and XRD were observed in the MMMs, indicating that the 2D nanofillers were compatible with the PES matrix. The MMMs show significantly enhanced gas separation properties where the highest selectivity was observed for 10 wt%PRG/Pebax membrane of 35.71 with CO2 permeability of 611 barrer and CH4 permeability of 17.11 barrer. These results confirm the possibility of using 2D nanofillers to develop high-performance membranes for gas separation.

A Study on Work Life Balance of Private Hospital Female Nurses with Special Reference to Manjeri Municipality, Malappuram District, Kerala
Authors: Yaseen.P Yaser
Published: July 2023

The nursing profession is facing many challenges in the current global scenario, including staff shortages, increased workload, and inadequate support. The complexity of the healthcare environment and the nature of the work itself make it difficult for nurses to balance their personal and professional lives. The issue of work-life balance is of particular concern for women in the nursing profession, as they continue to face gender-based discrimination and lack of support in the workplace. This paper aims to explore the various factors that contribute to the work-life balance of female nurses in the healthcare industry. The study will investigate the impact of organizational policies, work environment, job demands, and personal factors on the work-life balance of female nurses. The study will also analyze the coping strategies adopted by nurses to balance their personal and professional lives, and the effectiveness of such strategies in promoting work-life balance. The findings of this research will help in identifying the best practices for promoting work-life balance in the nursing profession, which can ultimately lead to better patient outcomes and a healthier workforce.
A mountain ridge model for quantifying oblique mountain wave propagation and distribution
Authors: Rhode Sebastian , Preusse Peter , Ern Manfred , Ungermann Jörn , Krasauskas Lukas , Bacmeister Julio , Riese Martin
Published: July 2023

Abstract. Following the current understanding of gravity waves (GWs) and especially mountain waves (MWs), they have a high potential for horizontal propagation from their source. This horizontal propagation and therefore the transport of energy is usually not well represented in MW parameterizations of numerical weather prediction and general circulation models. In this study, we present a mountain wave model (MWM) for the quantification of horizontal propagation of orographic gravity waves. This model determines MW source locations from topography data and estimates MW parameters from a fit of idealized Gaussian-shaped mountains to the elevation. Propagation and refraction of these MWs in the atmosphere are modeled using the Gravity-wave Regional Or Global Ray Tracer (GROGRAT). Ray tracing of each MW individually allows for an estimation of momentum transport due to both vertical and horizontal propagation. The MWM is a capable tool for the analysis of MW propagation and global MW activity and can support the understanding of observations and improvement of MW parameterizations in GCMs. This study presents the model itself and gives validations of MW-induced temperature perturbations to ECMWF Integrated Forecast System (IFS) numerical weather prediction data and estimations of GW momentum flux (GWMF) compared to HIgh Resolution Dynamics Limb Sounder (HIRDLS) satellite observations. The MWM is capable of reproducing the general features and amplitudes of both of these data sets and, in addition, is used to explain some observational features by investigating MW parameters along their trajectories.
Complex refractive index and single scattering albedo of Icelandic dust in the shortwave part of the spectrum

Abstract. Icelandic dust can impact the radiative budget in high-latitude regions directly by affecting light absorption and scattering and indirectly by
changing the surface albedo after dust deposition. This tends to produce a positive radiative forcing. However, the limited knowledge of the
spectral optical properties of Icelandic dust prevents an accurate assessment of these radiative effects. Here, the spectral single scattering
albedo (SSA) and the complex refractive index (m=n-ik) of Icelandic dust from five major emission hotspots were retrieved between
370–950 nm using online measurements of size distribution and spectral absorption (βabs) and scattering (βsca)
coefficients of particles suspended in a large-scale atmospheric simulation chamber. The SSA(λ) estimated from the measured
βabs and βsca increased from 0.90–0.94 at 370 nm to 0.94–0.96 at 950 nm in Icelandic dust from the
different hotspots, which falls within the range of mineral dust from northern Africa and eastern Asia. The spectral complex refractive index was
retrieved by minimizing the differences between the measured βabs and βsca and those computed using the Mie theory for
spherical and internally homogeneous particles, using the size distribution data as input. The real part of the complex refractive
index (n(λ)) was found to be 1.60–1.61 in the different samples and be independent of wavelength. The imaginary part (k(λ)) was
almost constant with wavelength and was found to be around 0.004 at 370 nm and 0.002–0.003 at 950 nm. The estimated complex
refractive index was close to the initial estimates based on the mineralogical composition, also suggesting that the high magnetite content observed
in Icelandic dust may contribute to its high absorption capacity in the shortwave part of the spectrum. The k(λ) values retrieved for Icelandic dust
are at the upper end of the reported range for low-latitude dust (e.g., from the Sahel). Furthermore, Icelandic dust tends to be more absorbing
towards the near-infrared. In Icelandic dust, k(λ) between 660–950 nm was 2–8 times higher than most of the dust samples sourced
in northern Africa and eastern Asia. This suggests that Icelandic dust may have a stronger positive direct radiative forcing on climate that has
not been accounted for in climate predictions.
Ground motion emissions due to wind turbines: observations, acoustic coupling, and attenuation relationships
Authors: Gaßner Laura , Ritter Joachim
Published: July 2023

Abstract. Emissions from wind turbines (WT) cover a wide range of infrasound and ground motions. When they are perceived as immissions by local residents,
they can become a source of disturbance or annoyance. To mitigate such disturbances, it is necessary to better understand and, if possible, suppress
WT-induced emissions. Within the project Inter-Wind we record and analyze ground motion signals in the vicinity of two wind farms on the Swabian Alb
in southern Germany, simultaneously with acoustic and meteorological measurements, as well as psychological surveys done by cooperating research
groups. The investigated wind farms consist of 3 and 16 WTs, respectively, and are located on the Alb peneplain at 700–800 m
height, approximately 300 m higher than the two municipalities considered in our study. Our main aim is to better understand reasons why
residents may be affected from WT immissions. Known ground motions include vibrations due to eigenmodes of the WT tower and blades, and the interaction between the passing blade and the tower,
causing signals at constant frequencies below 12 Hz. In addition, we observe signals in ground motion recordings at frequencies up
to 90 Hz which are proportional to the blade-passing frequency. We can correlate these signals with acoustic recordings and estimate sound
pressure to ground motion coupling transfer coefficients of 3–16.5 µms-1Pa-1. Sources for these emissions are the WT generator and possibly the
gearing box. The identification of such noise sources can help to find measures to reduce disturbances in order to increase the public acceptance of
WTs. Residents perceive more disturbance at the location where the wind farm is closer to the municipality (approximately 1 km). However,
there is also a major railway line which produces higher vibration and infrasound signal amplitudes compared to the WTs. Along the measurement lines the decay rate of the WT-induced ground motions is determined for a damping relation proportional to 1/rb. We find
frequency-dependent b values for different scenarios at our geological setting of Jurassic limestone on marl, sandstone, and Quaternary
deposits. These damping relationships can be used to estimate emissions in the far field and to plan mitigation strategies.
Black carbon concentrations and modeled smoke deposition fluxes to the bare-ice dark zone of the Greenland Ice Sheet
Authors: Khan Alia L. , Xian Peng , Schwarz Joshua P.
Published: July 2023

Abstract. Ice–albedo feedbacks in the ablation region of the Greenland Ice Sheet (GrIS) are difficult to constrain and model due, in part, to our limited understanding of the seasonal evolution of the bare-ice region. To help fill observational gaps, 13 surface samples were collected on the GrIS across the 2014 summer melt season from patches of snow and ice that were visibly light, medium, and dark colored. These samples were analyzed for their refractory black carbon (rBC) concentrations and size distributions with a single-particle soot photometer coupled to a characterized nebulizer. We present a size distribution of rBC in fresh snow on the GrIS and from the weathering crust in the bare-ice dark zone of the GrIS. The size distributions from the weathering crust samples appear unimodal and were overall smaller than the fresh snow sample, with a peak around 0.3 µm. The fresh snow sample contained very large rBC particles that had a pronounced bimodality in the peak size distributions, with peaks around 0.2 and 2 µm. rBC
concentrations ranged from a minimum of 3 µg-rBC/L-H2O in light-colored patches at the beginning and end of the melt season to a maximum of 32 µg-rBC/L-H2O in a dark patch in early August. On average, the rBC concentrations were higher (20 ± 10 µg-rBC/L-H2O) in patches that were visibly dark, compared to medium patches (7 ± 2 µg-rBC/L-H2O) and light patches (4 ± 1 µg-rBC/L-H2O), suggesting that BC aggregation contributed to snow aging on the GrIS, and vice versa. Additionally, concentrations peaked in light and dark patches in early August, which is likely due to smoke transport from wildfires in northern Canada and Alaska, as supported by the Navy Aerosol Analysis and Prediction System (NAAPS) reanalysis model. According to the model output, 26 mg m−3 of biomass-burning-derived smoke was deposited between 1 April and 30 August, of which 85 % came from wet deposition, and 67 % was deposited during our sample collection time frame. The increase in the rBC concentration and size distributions immediately after the modeled smoke deposition fluxes suggest that biomass burning smoke is a source of BC to the dark zone of the GrIS. Thus, the role of BC in the seasonal evolution of the ice–albedo feedbacks should continue to be investigated in the weathering crust of the bare-ice zone of the GrIS.
Modelling the impact of trapped lee waves on offshore wind farm power output
Authors: Ollier Sarah J. , Watson Simon J.
Published: July 2023

Abstract. Mesoscale meteorological phenomena, including atmospheric
gravity waves (AGWs) and including trapped lee waves (TLWs), can result from
flow over topography or coastal transition in the presence of stable
atmospheric stratification, particularly with strong capping inversions.
Satellite images show that topographically forced TLWs frequently occur
around near-coastal offshore wind farms. Yet current understanding of how
they interact with individual turbines and whole farm energy output is
limited. This parametric study investigates the potential impact of TLWs on
a UK near-coastal offshore wind farm, Westermost Rough (WMR), resulting from
westerly–southwesterly flow over topography in the southeast of England. Computational fluid dynamics (CFD) modelling (using Ansys CFX) of TLW
situations based on real atmospheric conditions at WMR was used to better
understand turbine level and whole wind farm performance in this parametric
study based on real inflow conditions. These simulations indicated that TLWs
have the potential to significantly alter the wind speeds experienced by and
the resultant power output of individual turbines and the whole wind farm.
The location of the wind farm in the TLW wave cycle was an important factor
in determining the magnitude of TLW impacts, given the expected wavelength
of the TLW. Where the TLW trough was coincident with the wind farm, the
turbine wind speeds and power outputs were more substantially reduced
compared with when the TLW peak was coincident with the location of the wind
farm. These reductions were mediated by turbine wind speeds and wake losses
being superimposed on the TLW. However, the same initial flow conditions
interacting with topography under different atmospheric stability settings
produce differing near-wind-farm flow. Factors influencing the flow within
the wind farm under the different stability conditions include differing,
hill and coastal transition recovery, wind farm blockage effects, and wake
recovery. Determining how much of the differences in wind speed and power
output in the wind farm resulted from the TLW is an area for future
development.
THERMAL DIFFUSION, AND THERMAL RADIATION EFFECTS ON UNSTEADY MHD CONVECTIVE FLOW PAST AN INCLINED VERTICAL PLATE
Authors: Das NABANITA , Sarma Subhrajit , Ahmed Nazibuddin
Published: July 2023

In this investigation, thermal diffusion and thermal radiation effects are studied on an unsteady natural convective flow of an electrically conducting fluid past an inclined vertical plate. A uniform aligned magnetic field is imposed onto the fluid or the plate. The governing PDEs are solved using the Laplace transformation technique. The effect of various parameters on velocity, temperature, concentration, skin friction, Nusselt number, and Sherwood number are analyzed graphically. It is observed that velocity field rises for increasing the value of the thermal-diffusion effect. Moreover, fluid concentration gets ososcillate with the effect of Prandtl number and thermal radiation parameter.

Published: July 2023

This study aimed to evaluate the potential use of olive seed pulp powder (BOP), a by-product of the olive oil industry, as a functional raw material. The physicochemical, rheological, and bioactive properties and consumer acceptance preferences of bread produced by adding wheat flour at 1%, 2.5%, 5%, and 7.5% ratios were investigated. Depending on the increase in BOP addition, it decreased the stickiness and specific volume of the bread and increased the brown index, hardness, and stickiness values. The increase in BOP addition in both the shell and the core increased phenolic and antioxidant activity. The BOP shot had a positive impact on consumer preference. The 5% and 7.5% BOP are more stable and of good quality in terms of preserving shape due to lower exponents. For this reason, BOP appears to be a good candidate for enriching bread on an industrial scale
CONVECTIVE MHD FLOW PAST AN IMPULSIVELY STARTED VERTICAL PLATE WITH PERIODIC TEMPERATURE AND CONCENTRATION IN PRESENCE OF THERMAL RADIATION AND CHEMICAL REACTION
Authors: Mridusmita Bormudoi  , Nazibuddin Ahmed  , Rajdeep Bordoloi
Published: July 2023

This study investigated a two-dimensional unsteady MHD-free convection of a viscous, incompressible fluid past through an impulsively started vertical plate in the presence of thermal radiation and chemical reactions. The Laplace transform method is used to solve the second-order partial differential equations. The effect of various related parameters on the velocity field, temperature field, and concentration field are demonstrated graphically. The effects of the Nusselt number, Sherwood number, and skin friction for the influence of different parameters are also graphically visualized. It is noticed that the increment in Soret number hikes the fluid velocity and concentration. Also, the Hartmann number reduces the velocity of the fluid. Present work is important in various industrial and engineering sectors, such as chemical and power industries, glass production, steel rolling etc.
ROBUST TRACKING IN TWO-DEGREE-OF-FREEDOM CONTROL SYSTEMS: MAGNETIC LEVITATION SYSTEM
Authors: TEPPA Pedro , FAGGIONI Miguel
Published: July 2023

The fundamental result of this work is to provide a connection between an input-output model such as a two-degree-of freedom control system and an equivalent model in the state-space, whose state vector depends exclusively on the measurable information of the original system provided by its outputs. This allows taking advantage of powerful numerical methods to perform controller synthesis and then come back to the two-degree-of-freedom control system for the implementation of the controller. This work focused on state-feedback control laws that ensure robust performance. The effectiveness of the method is validated through the application on the magnetic levitation system.

Published: July 2023

This study aims to investigate the chemical composition and acetylcholinesterase activity of essential oil from Syzygium pyrifolium leaves. The essential oil was obtained by hydrodistillation in a Clevenger-type apparatus and its chemical composition was analyzed by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Thirty-two volatile components were identified in S. pyrifolium leaves oil, including geraniol (73.8%), ?-pinene (7.0%), ?-pinene (5.7%) and (E)-?-ocimene (4.5%) as the major components. Acetylcholinesterase activity was evaluated using Ellman method and the essential oil showed strong inhibitory activity (I%: 82.5%). Our findings demonstrate that S. pyrifolium essential oil could be useful for an alternative raw material of food and medicinal products for pharmaceutical applications.
MHD FLOW IN POROUS MEDIUM THROUGH AN EXPONENTIALLY STRETCHING SHEET WITH SURFACE HEAT AND MASS FLUX UNDER THE IMPACT OF CHEMICAL REACTION
Authors: Krishnandan Verma
Published: July 2023

The key motive of the present study is to examine the heat and mass transmission process through a sheet that is assumed to be stretching exponentially in porous medium on MHD flow with suction, constant surface heat and mass flux. The governing equations of the problem are first made dimensionless by adopting suitable non-dimensional transformations, there after it is solved by bvp4c, a Matlab inbuilt solver. The solutions are presented by graphs and numerical values are computed for rate of heat transfer, rate of mass transfer and skin-friction coefficient. The validity of the present result is also checked by comparing the result with previously published work. The findings reveal that suction parameter helps in reducing the fluid velocity and heat transfer rate, and mass transfer is boosted by permeability parameter. Other important parameters also showed noticeable consequences on both heat as well as mass transfer process.
EXAMINATION OF COMPOSITE DISC SPRINGS
Authors: Karasu Hasim Firat , Belevi Melih
Published: July 2023

This study aims to produce composite disc springs from carbon prepreg material, which is close to the characteristic curve of the steel disc spring or better than steel, which constitutes a group of machine elements. In this way, the design will be lightened without significantly diverging from the force/deformation ratio of the disc spring. For this, first of all, a standard steel disc spring was selected, and its characteris-tic curve was determined by the finite element analysis method. For the composite disc springs to be pro-duced, the selected steel disc spring geometry was taken as reference, and different cone heights (taper angles) and different orientation angles of the carbon prepreg layers were determined as variable parame-ters. For all these parameters, finite element analyses were made for the carbon prepreg material in the ANSYS Workbench module, and the disc springs de-signed using these analyses were produced by the autoclave method in a closed mold and tested. As a result of compression tests, spring characteristics of steel and composite disc springs were obtained and compared. The results reveal that composite disc springs produced in certain parameters have more suitable characteristics than steel disc springs.

Recursive identification algorithms for the parameter estimation of linear systems from multilevel quantized outputs are introduced in this paper. The proposed algorithms are proved to be optimal in the sense that they minimize the a posteriori parameter estimation error covariance matrix. Numerical simulations are carried out to illustrate their performance for different quantization steps and Signal-to-Noise Ratios, as well as their capability to track time varying parameters.
A GROUP MANAGEMENT SCHEME OF VEHICLE NETWORKING BASED ON HIERARCHICAL DISTRIBUTION
Authors: Wang Xiaoliang , Yue H. , She Xinhui
Published: July 2023

We introduce and implement a new centralized distribution algorithm and apply it to the vehicle networking environment, reconstruct the principle structure of the one-way function binary tree based on the Chinese remainder theorem, and generate the final group key from the bottom up. The analysis shows that the final data distribution can be reduced to the logarithmic level of the traditional centralized distribution data. In the aspect of authentication, we use the elliptic curve signature algorithm (ECDSA), which is more lightweight than RSA and DSA signature algorithm, which makes it more able to adapt to the fast-moving vehicle network environment, faster and more convenient to authenticate and manage the vehicles in the coverage area. Experiments show that our model can be applied to mobile and large number of node environments, and can achieve anonymity, traceability, non-repudiation and backward security in terms of security.
