Low-power and high-speed approximate multiplier using higher order compressors for measurement systems
Authors: Prasad M. V. S. Ram , Kushwanth B. , Bharadwaj P. R. D. , Teja P. T. Sai 
Published: June 2022

At present, approximate multipliers are used in the image processing applications. These approximate multipliers are designed with the help of higher order compressors to decrease the number of addition stages involved for the lessening stages. The approximate computing is the best technique to improve the power efficiency and reduce delay path. With the use of approximate computing multiple compressors are designed. In this paper, 10:2 compressors are designed and implemented in the 32-bit multiplier and compared with the exact 32-bit multipliers. The proposed higher bit compressors along with the lower bit compressors are implemented to reduce the delay of the design. This type of digital circuits has much significance in measurement technologies, for enabling fast and accurate measurements. With the use of approximate compressors, the result may be ineffective, but the power consumption and delay are getting reduced. Hence, these proposed multipliers are only implemented the digital signal processing applications, where there is need for combining two or more signals. The proposed multiplier is used for implementing FIR filter resulted 27 ns delay which is far better than the exact multiplier having 119 ns. These multipliers also used in image processing applications and PSNR of image has been employed.
Hospital-Based Rapid Recovery Protocol in Knee Arthroplasty
Authors: Spadaccini Carmine J. 
Published: June 2022

This review aims to determine the elements a hospital-based knee arthroplasty program should consider when developing a rapid recovery protocol. It will examine the perioperative pathway and how a program can break down each phase for success. Secondary objectives of this review include how and why the culture surrounding knee arthroplasty has changed and why it is in a hospital's best interest to adopt a rapid recovery pathway in light of this new landscape. An extensive search was performed through databases which included Still OneSearch, EBSCOhost, and PubMed. Sources aligned with the review's objectives. Inclusion criteria involved primary sources, secondary sources, and peer-reviewed articles less than 5 years old. On finding primary and secondary sources, reference sections provided additional materials to ensure high-quality research.
Outpatient knee arthroplasty has gained interest in the past 10 years, and rapid recovery protocols have helped promote this likely development. The rapidly changing landscape surrounding knee arthroplasty was triggered by insurance companies and pushed even further because of the COVID-19 pandemic. Developing a rapid recovery protocol in the hospital setting involves a change in overall culture, interprofessional participation, and patient and family cooperation. Although not an easy task, adopting a rapid recovery protocol for knee arthroplasty has been shown to improve overall patient outcomes by decreasing length of stay, decreasing complications, and increasing discharge home rates. Along with improved outcomes, we have improvements in patient satisfaction and overall cost savings.
Origin of the Paleoproterozoic “Giant Quartz Reef” System in the Bundelkhand Craton, India: Constraints from Fluid Inclusion Microthermometry, Raman Spectroscopy, and Geochemical Modelling

Abstract
The Bundelkhand “giant quartz reef” (BGQR) system comprises 20 major quartz reefs which run for tens of km in strike length of average width of 40 m and occurs in spatial intervals of 12–19 km in the Bundelkhand craton, North Central India. The BGQR system is distinct from quartz vein systems originating from crustal scale shearing observed in ancient as well as modern convergent tectonic settings. Fluid inclusions studied in BGQR system are intriguingly diverse although dominated by aqueous fluid which exhibit a broad range of salinity from ~0 to 28.9 wt% NaCl equivalent and temperature of homogenization range of 58 to 385°C. Primary and pseudosecondary aqueous inclusions in assemblages in grain interiors and growth zones vary randomly in their Th—salinity characteristics that preclude identification of discrete fluid events. Aqueous fluid in the BGQR system evolved through mixing of two distinct sources of fluids—a meteoric fluid and a moderate temperature—moderate salinity fluid that was possibly derived from the Bundelkhand granodiorite based on an important clue provided by hydrous mineral bearing fluid inclusions detected by Raman microspectrometry. The results of modeling with PHREEQC indicate that mixing of fluids could be a suitable mechanism in formation of these giant reefs. The available 1-dimensional diffusive transport model for deposition of silica helps in putting constraints on the time span of deposition of silica in the context of the BGQR system. The BGQR system is a possible result of shallow-crustal sources of fluid and silica and could be visualized as a “Paleoproterozoic geothermal system” in a granitic terrane.
The Ultimate Breakthrough for Drilling Automation May Be Simply Finding a Business Case
Authors: Jacobs Trent 
Published: June 2022

The biggest meeting of the year dedicated solely to the topic of drilling automation revealed that the ultimate barrier facing this emerging development is not the technology. It’s how the business of drilling is done.
This is according to many of the technical professionals that participated in a recent symposium held jointly by SPE’s Drilling Systems Automation Technical Section (DSATS) and the IADC’s Advanced Rig Technology Committee.
The annual event held in conjunction with the IADC/SPE International Drilling Conference and Exhibition departed from its usual format of speakers issuing well-rehearsed presentations.
Instead, it took on the form of a multipronged focus group that saw dozens of participants hailing from operators, drilling contractors, and service companies who huddled into the four corners of a conference ballroom in Galveston, Texas. Their chief objective was to help update the DSATS’s “roadmap” that identifies which technological breakthroughs are needed to bring about a true step change in drilling automation by 2025.
But as that year draws near, the odds of reaching most of the key milestones are dimming, and so, the symposium leaders decided to instead look toward what should be achieved by 2030.
What DSATS wants to see become possible in the coming years is a rig in which “well plans are uploaded into an interoperable drilling system that automatically delivers a quality wellbore into the best geological location.”
Though we have seen pieces of drilling automation come together in recent years—among others, this includes automated rig floors and automated rotary steerable systems (RSS)—we have not seen a truly automated rig as outlined above.
And few of those attending the meeting expressed optimism that such a development is within reach.
“We are not trending toward hitting this vision in 2025,” said Esben Thorup, who was speaking from the perspective of an offshore drilling contractor. “We see pilot projects heading in the right direction, but wide adoption of automation is not happening.”
Thorup is the head of digital innovation with Maersk Drilling (and soon to be Noble Corp. upon the impending finalization of a $3.4 billion merger announced in November 2021). He was one of several panelists tapped to lead the four focus groups and offer back to the entire gathering some key points raised during those discussions.
For Thorup, the biggest thorn in the side of drilling automation is the business case, or lack thereof.
“We would absolutely love to put automation systems on all of our rigs,” he said while noting that some automated components have been deployed on Maersk’s rigs. “But we are not necessarily being rewarded often.”
Dan Hoffarth, CEO of onshore contractor Citadel Drilling, led another group and seemed to echo his offshore counterpart in asking the big question of the day: “Does our business model work as individual companies?”

Abstract
The nanoparticles of Polyaniline/Fe0.90Zn0.10Fe2O4 (PANI/Fe0.90Zn0.10Fe2O4) were synthesized by a co-precipitation method and an in-situ polymerization method. XRD patterns showed that the Fe0.90Zn0.10Fe2O4 grain size about 11.8 nm, while TEM image showed grain size from 10 to 18 nm. The results of FT-IR spectra and DTA analyses showed that PANI participated in nanocomposite samples. The grain size of PANI/Fe0.90Zn0.10Fe2O4 samples measured by SEM was about 35–50 nm. The magnetization measurements showed that the saturation magnetic moment of PANI/Fe0.90Zn0.10Fe2O4 samples at 300 K decreased from 71.5 to 43 emu/g when PANI/Fe0.90Zn0.10Fe2O4 mass ratio increased from 0–40%. The arsenic adsorption capacity of nanocomposite samples with different PANI concentration was investigated in solutions of pH 1 to pH 14. The qmax maximum arsenic adsorption capacities were calculated by the Langmuir isotherm equation at pH 7 and 300 K. The evaluated results show that with mass ratio of 0.9%, the sample S1 with qmax = 43.48 mg/g is higher than that Fe3O4 nanoparticles. In addition, the substitution of Fe2+ ions by Zn2+ ions in Fe0.90Zn0.10Fe2O4 and PANI coating were improving more magnetic and chemical stable of samples over time. Other hand, these materials could be reused after desorption in solution at pH 14.
Research plan for evaluating user satisfaction of public art museums through on-site survey using Indicators for Art Museums (IAM) scale with three question sections
Authors: Iwakiri Momone , Moteki Yasutoshi 
Published: June 2022

Abstract
We examine the methods for evaluating user satisfaction in public art museums. Specifically, we will conduct a multi-group questionnaire survey of museum users on their satisfaction with the services provided by public museums. Using selective multigroup principal component regression analysis—which combines principal component analysis and multiple regression analysis—we will statistically examine the factors that public art museums should emphasize when providing services to their users. The four-page questionnaire will comprise three sections: hardware (building and interior), software (staff responses), and exhibition content. We named the survey scale the Indicators for Art Museums’ (IAM’s) user satisfaction scale. The eventual survey will be conducted at the Higashihiroshima City Museum of Art for six business days on the third week of August 2022. Self-administered questionnaires will be distributed to visitors to the special exhibition. Our proposed scale is simpler than the existing SERVQUAL-based survey framework, which is a 5-section scale, and can reduce the burden on respondents and increase the response rate. Learning the opinions of those in charge of art museums from the very beginning of the formulation of the research framework also aids in the accuracy of the analytical model to be applied.
Households’ Censored Mobile Phone Spending and Its Determinants in Turkey: An Inverse-Hyperbolic Sine Double-hurdle Model
Authors: Cengiz Vedat , urak faruk , Bilgic Abdulbaki , Yen Steven T , Efekan Erkan 
Published: June 2022

Abstract
The roles of socio-demographic and economic characteristics in the probability and levels of household mobile phone spending were determined by estimating the inverse hyperbolic sine double-hurdle model (IHS-DH). Data were obtained from the Household Budget Surveys conducted by the Turkish Statistical Institute (TSI) during 2019. The IHS-DH model has a statistical advantage over all other competing models. In addition, statistical test results have provided support for the heteroscedastic error specification and use of instruments in parameter identification. Findings suggest that most of the socio-demographic and economic characteristics of the household and the head of household have significant effects on the probability to spend and levels of spending on mobile phones. In particular, the creation of different policy and intervention structures suitable for the statistically significant characteristics of the family will both ensure the efficiency of resource allocation and facilitate the adoption of appropriate marketing strategies in the country. The Global System for Mobile Communications operators are thought to be one of the biggest beneficiaries of the returns to be received from all kinds of subventions or investment incentives made in areas where the telecommunication infrastructure is insufficient.
Compact modelling of nanocluster functionality as a higher-order neuron.
Authors: Lawrence Celestine 
Published: June 2022

Abstract
Disordered nanoclusters with multi-electrode input-output functionality had recently been experimentally realized with energy-efficient and emergent computational capacity, and thus an interconnected network of several such nanoclusters had been proposed to realize artificial neural networks. To aid that end, here we show that nanocluster functionality can be fit to the simplest dendritic neuron model, where the only form of nonlinearity is due to multiplicative interactions. This work brings in to the spotlight higher-order neural networks (known for their efficient encoding of geometric invariances) to serve as an explainable baseline model of nano-networks against which experimentalists can compare more sophisticated models (deep neural networks or physics-based models such as the lin-min network introduced here); and provides ground for designing novel approximate hardware and a statistical mechanics analysis of the learning performance of interconnected nanoclusters vs. perceptrons (where neurons output a nonlinear function of the weighted sum of their inputs). A network with just 10 higher-order neurons is shown to achieve a classification accuracy of more than 96% on the MNIST benchmark for handwritten digit recognition (which required 100 times more neurons in 3-layer perceptrons).
Development and validation of a quantitative food frequency questionnaire to assess free sugar intake among Sri Lankan preschool children
Authors: Mututanthri Shanika , Thoradeniya Tharanga , Samaranayake Anil , Harris Rebecca 
Published: June 2022

Abstract
Background
Monitoring the free sugar intake of preschool children is important for population health surveillance and evaluation of community-wide efforts at noncommunicable diseases and dental caries prevention. Appropriate dietary assessment tools are also needed to underpin clinical prevention for patients. Thus, an appropriate dietary assessment tool applicable for large-scale, community-based studies without an excessive participant burden is needed, such as a quantitative food frequency questionnaire (FFQ) that assesses dietary data retrospectively. Such tools also need to be tailored and validated for the cultural context and population concerned. Sri Lanka is currently lacking such a tool for use among its preschool population.
Methods
In the development phase, a sample of 518 preschool children and their caregivers were selected from preschools in the District of Colombo, Sri Lanka. Three 24-hour dietary recalls (24hDR) were collected from each child and based on that, a 67-item FFQ was developed, including commonly consumed free sugar-containing food items. In the validation phase, 108 pairs of preschool children aged 04-05-years, and their caregivers participated. The relative validity of the FFQ was assessed by comparing it with three, (24hDRs). The test-retest reliability was assessed by repeated application of the FFQ to the same population after six weeks.
Results
The free sugar intake values calculated from the FFQ when compared with three, 24hDRs indicated a good correlation, good agreement in cross classifying participants to tertiles based on their free sugar intake levels and a good agreement in bland and Altman graphs at different food group levels and total free sugar intake. The FFQ measured sugar intake levels slightly higher than three 24-hour dietary recalls. Similarly, the free sugar intake values calculated by repeated application of the FFQ also showed a good agreement at the group and individual levels as well as a good correlation.
Conclusion
The newly developed quantitative FFQ was found as a valid and reliable instrument to assess the free sugar intake among preschool children quantitatively as a total or by different food and beverage group levels.

Published: June 2022

Abstract
Objective
Optic nerve head drusen (ONHD), peripapillary hyperreflective ovoid mass like structures (PHOMS) and horizontal hyperreflective lines (HHL) are commonly seen in eyes with pseudopapilledema on enhanced depth imaging (EDI) spectral domain optical coherence tomography (SDOCT) .The objective of this study is to assess the frequency of ONHD, PHOMS and HHL on spectral domain OCT in the eyes diagnosed to pseudopapilledema
Methods
A retrospective case control study included patients diagnosed as pseudopapilledema and EDI SD OCT imaging of the optic nerve head (n = 48 eyes) and controls (n = 20 eyes) Volumetric OCT scans through the optic nerve head were studied to diagnose ONHD, HHL and PHOMS. One proportion z test was used to find the difference in proportions .
Results
48 eyes of 27 subjects were studied. ONHD as described by the optic disc drusen study consortium was noted in 19 eyes (39.48%), p value-0.032 ,PHOMS in 31 eyes (64.6%),p value 0.043,HL in 19 eyes (39.48%) ,p value-0.032, and none of the normals had ONHD,PHOMS and HHL.
Conclusions
PHOMS are more frequently seen than ONHD and HHL in eyes with pseudopapilledema.

Authors: wang jing , Hu Bin-Fei , Wang Guan-Ling 
Published: June 2022

Abstract
Purpose: Anthracyclines are indispensable drugs for induction therapy in childhood acute lymphoblastic leukemia (ALL). Idarubicin (IDA) and Epirubicin (EPI) are the most frequently used anthracyclines agents. Here, we report a retrospective study comparing the acute toxicities of the two drugs in pediatric ALL. Methods: From April 2018 to 2021, we enrolled forty-one children with untreated ALL. Patients were assigned to induction therapy, consisting of either EPI (30 mg/m2 ) or IDA (8 mg/m2). Acute hematological and cardiac toxicities which consisted of brain natriuretic peptide (BNP), Echocardiography, Peripheral blood cell count,and minimal residual disease (MRD) were evaluated. Results: Ultrasound cardiography and BNP revealed no significant difference in terms of cardiac function between groups. What’s more, acute hematological toxicity during the early stage was similar between the two groups. Further, MRD between the two groups were identical.Conclusions: We found that acute hematological and cardiac toxicity were approximately the same between the two groups during induction chemotherapy.

Abstract
Background: Chronic obstructive pulmonary disease (COPD) is a highly morbid and heterogenous disease. While COPD is defined by spirometry, many COPD characteristics are seen in cigarette smokers with normal spirometry. The extent to which COPD and COPD heterogeneity is captured in omics of lung tissue is not known. Methods: We clustered gene expression and methylation data in 78 lung tissue samples from former smokers with normal lung function or severe COPD. We applied two integrative omics clustering methods: 1) Similarity Network Fusion (SNF) and 2) Entropy-Based Consensus Clustering (ECC). Results: SNF clusters were not significantly different by percentage of COPD cases (48.8% vs. 68.6%, p = 0.13), though were different according to median forced expiratory volume in one second (FEV1) % predicted (82 vs. 31, p=0.017). In contrast, the ECC clusters showed stronger evidence of separation by COPD case status (48.2% vs. 81.8%, p = 0.013) and similar stratification by median FEV1 % predicted (82 vs. 30.5, p=0.0059). ECC clusters using both gene expression and methylation were identical to the ECC clustering solution generated using methylation data alone. Both methods selected clusters with differentially expressed transcripts enriched for interleukin signaling and immunoregulatory interactions between lymphoid and non-lymphoid cells. Conclusions: Unsupervised clustering analysis from integrated gene expression and methylation data in lung tissue resulted in clusters with modest concordance with COPD, though were enriched in pathways potentially contributing to COPD-related pathology and heterogeneity.

Abstract
High levels of circulating adiponectin are associated with increased insulin sensitivity, low diabetes prevalence, and low BMI; however, high levels of circulating adiponectin are also associated with increased mortality in the 60s and 70s. This study analyzes the characteristics and physiological significance of circulating high-molecular-weight (cHMW) adiponectin levels in the very old (85–89 years old) and centenarians. We found that cHMW adiponectin levels increased significantly beyond 100 years of age, were negatively associated with diabetes prevalence, and were associated with single nucleotide variants in CDH13 and ADIPOQ. Multivariate regression analysis revealed that genetic variants, BMI, and lipids were major factors associated with cHMW adiponectin levels in the very old. However, the same factors showed less or no association in centenarians. High levels of cHMW adiponectin in very older men with low BMI were significantly associated with mortality, while no such relationship was found for very older women or centenarians.
Salinity causes widespread restriction of methane emissions from inland waters

Published: June 2022

Abstract
Inland waters are the largest natural source of methane (CH4), a potent greenhouse gas, but models and estimates of aquatic CH4 cycling and emissions were developed in soft-water ecosystems and may not apply to globally abundant salt-rich inland waters. Here we show that elevated salinity constrains microbial CH4 cycling restricting aquatic emissions at large scales. Our survey of the Canadian Prairie ecozone demonstrates that salinity interacts with organic matter availability to shape CH4 patterns across aquatic networks (rivers, lakes, wetlands, and agricultural ponds). Current empirical models, biased toward solute-poor surface waters, overestimated CH4 concentrations and emissions measured in hardwater systems by up to several orders of magnitude, with discrepancies strongly linked to salinity. Models were particularly inaccurate for bubble-mediated emissions from small lentic systems, one of the largest sources of aquatic CH4 globally. Elevated salinity reduced aquatic CH4 emissions by an estimated 81 % in the Canadian Prairies, and could result in a 7.8 % overestimation of global lentic emissions. Widespread salinization of inland waters under future land use and climate regimes could further restrict methane emissions.
