Aerostatic and Aerodynamic Performance of an Out-Pump Spirally Grooved Thrust Bearing: Analysis and Comparisons to Static Load Experiments

Field: Engineering (Physical Sciences)

Abstract The combined effects of external pressurization and out-pump spiral grooves are studied according to the incompressible fluid Whipple analysis on spirally grooved gas bearings. The results are examined in terms of non-dimensional parameters that bring out the interaction between the action of spiral groove self-pressurization and external pressurization through orifices. It is found that interaction is beneficial when the supply pressure level to the orifices is near the peak pressure that can be reached by the spiral grooves alone. An optimized interacting design can improve the bearing stiffness and load carrying capacity. However, when the action of spiral groove self-pressurization dominates, the orifices are merely a resistance of inlet because of the strong out-pump action of spiral grooves. On the other hand, when the action of external pressurization dominates, the spiral grooves still add to the bearing stiffness and load-carrying capacity even though the action of the spiral groove self-pressurization is at a low level. The orifice flow tends to be saturated ahead because of the spiral grooves in stationary state and their out-pump self-pressurization in steady state. Out-pump spiral grooving is found to be the preferred configuration to combine aerostatic and aerodynamic actions. These predicted trends are qualitatively substantiated by static load tests without rotation.

Optimization of the K-Nearest Neighbor Algorithm to Predict Bank Churn

Field: Computer Science (Physical Sciences)

Bank churn occurs when customers switch from one bank to another. Although some customer loss is unavoidable, it is important for banks to avoid voluntary churn as it is easier and cheaper to keep an existing customer than to gain a new one. In our paper, we train and optimize a machine learning algorithm, specifically a k-nearest neighbors algorithm, to predict whether or not a customer will leave their bank using existing demographic and financial information. Bygiving banks a reliable method for predicting whether or not a customer will churn, they can prioritize certain groups in an effort to increase retention rates. We compare the accuracy of our algorithm to other types of machine learning algorithms, such as random forest and logistic regression models, and increase the accuracy of the k-nearest neighbor algorithm by optimizing the k value used in our model, as well as utilizing 10-folds cross-validation. We determine the most important attributes and weight them appropriately. After optimizing this model, we are able to predict with 85.72% accuracy whether or not the customer will churn.
Country Size and Strategic Trade Policy: A Model of a Dominant Country Facing a Competitive Fringe

Field: Economics, Econometrics and Finance (Social Sciences)

This paper develops a theory for why a large country might be special when it comes to pursuing strategic trade policy. Traditional theory holds that, a large country should hold back its exports to improve its terms of trade. However, if the learning-by-doing effect exists, then a large country has an incentive to subsidize exports. In this paper, I present a formal industrial organization (IO) model to capture this story. I embed this IO structure into a trade model with three goods. I also conduct some counter-factual analysis and welfare analysis about various trade policies of the importer countries.
Conventional weapons

Field: Social Sciences (Social Sciences)

All the military conflicts since 1945 have been fought with so-called conventional, or non-nuclear, weapons. The global annual military expenditure on such armaments and forces is generally estimated to account for over 80 per cent of the total annual military expenditure. Nevertheless, comparatively little attention has been paid to the conventional weapons aspect of the arms race in international disarmament efforts since the Second World War. The main reason for this is perhaps the wide recognition that conventional war does not threaten the survival of mankind as could a nuclear war. The international community has therefore focused on attempts to bring about nuclear disarmament and to prohibit various kinds of weapons of mass destruction. The potential destructiveness of conventional war has nevertheless been steadily rising, as ever more sophisticated conventional weapons have been developed and acquired by armed forces world-wide.
Perfect the Puff: Reinforcing Metered-dose Inhaler Excellence amongst Primary Care Trainees for Optimal Asthma Management

Field: Health Professions (Health Sciences)

Background: There are key gaps regarding proper metered-dose inhaler (MDI) technique during Internal Medicine Residency training. Inhaler misuse remains common, underscoring the need for continued reinforcement. This study aims to assess the efficacy of one training session, which reviews the 8 steps for MDI use. Methods: We recruited 30 Internal Medicine resident volunteers at an urban medical center with a high community prevalence of asthma to participate in a teaching session that included 8 core steps for proper MDI use. We administered a pre-survey asked about trainees’ prior teaching and how they currently teach and assess the MDI technique. Participants completed a post-intervention survey listing the MDI steps. Results: Most were not previously taught the MDI technique (n=21), and whether one was previously taught the MDI technique did not differ by gender (p=0.94) nor class year (p>0.99). Of the participants who were previously taught the MDI technique (n=9), no participants were confident in assessing the technique (0%) nor providing a demonstration (0%), though most (67%) of these individuals felt they could verbally teach the MDI technique. Pre to post-survey findings demonstrated an average improvement of 3.6 to 6.6 MDI steps correctly identified (p< 0.01). The implications of these findings underscore the need to not only teach IM residents about the MDI technique but also ensure continuous reinforcement regardless of gender or level of training. Conclusion: Reinforcing the MDI technique through a training session is an intervention to enhance IM residents’ knowledge. Future studies can assess the impact of longitudinal training through digital education tools and assess the retention of MDI technique knowledge. Recommendations for future training sessions could assess the impact of digital education as well as other modalities such as visual aids and hands-on training.

Differences in Attitudes Toward Catalog Retailers of Apparel Among Social/Economic Risk Orientation Groups

Field: Business, Management and Accounting (Social Sciences)

This research examined whether perceived social/economic risk related to apparel products influenced attitudes about attributes of apparel catalog retailers, overall attitude toward apparel catalog retailers, and actual purchase of apparel from catalogs. Self administered questionnaires were mailed to a random sample of catalog shoppers resulting in 458 respondents. Data were collected on levels of economic and social risks perceived for purchasing apparel, the importance of various apparel shopping needs and wants, and the belief that catalog retailers possessed attributes that met apparel shopping needs and wants. Results revealed that level of social/ economic risk did influence attitudes toward catalog attributes of economic utility, home environment, merchandise assortment, catalog clientele, and interaction with catalog personnel. Levels of socialleconomic risk also influenced annual apparel expenditures from catalogs but did not affect overall attitude toward catalog retailers and number of annual apparel purchases from catalogs.
Outcome after treatment for sebaceous carcinoma: A multicenter study

Field: Medicine (Health Sciences)

Abstract Background Sebaceous carcinoma (SC) is a rare malignant tumour whereby, comprehensive long‐term data are scarce. This study aimed to assess the outcome of patients treated with resection for SC. Methods Patients treated at four tertiary centres were included. Cumulative incidence curves were calculated for recurrences. Results A total of 100 patients (57 males, 57%) were included with 103 SCs. The median age was 72 (range, 15–95) years with a median follow‐up of 52 (interquartile range [IQR], 24‐93) months. Most SCs were located (peri)ocular (49.5%). Of all SCs, 17 locally recurred (16.5%) with a median time to recurrence of 19 (IQR, 8–29) months. The cumulative incidence probability for recurrence was statistically higher for (peri)ocular tumours ( p = 0.005), and for positive resection margins ( p = 0.001). Two patients presented with lymph node metastases and additional seven patients (8.7%) developed lymph node metastases during follow‐up with a median time to metastases of 8 (IQR, 0.5–28) months. Three patients had concurrent in‐transit metastases and one patient also developed liver and bone metastases during follow‐up. Conclusion SC is a rare, yet locally aggressive tumour. Positive resection margins and (peri)ocular SCs are more frequently associated with local recurrence. SC infrequently presents with locoregional or distant metastases.

Field: Agricultural and Biological Sciences (Life Sciences)

Incidence of yellow vein net disease with leaf distortion was observed on Malva parviflora grown as a weed in Barkatullah University campus, Bhopal, India during the rainy session. The begomovirus disease was suspected on the basis of symptomatology and whiteflies insects’ population on the plant. The begomovirus was detected by the PCR with the begomovirus gene specific primers. The begomovirus under study showed highest nucleotide sequence identities and distinct phylogenetic relationships of coat protein gene (CP) with several isolates of Tomato leaf curl Kerala virus (ToLCKeV). This is the first report of ToLCKeV associated with yellow vein net disease on M. parviflora and it is a new host of begomovirus from India.
Newborn hypernatremic dehydration: A prospective study reducing the usage of intravenous liquids in moderate cases

Field: Medicine (Health Sciences)

Objectives The rehydration approach for hypernatremic dehydration in newborns is challenging. A new treatment protocol was introduced in the NICU for moderate hypernatremic dehydrated (MHD) newborns to achieve safer and more effective serum sodium (Na+) correction. Methods A prospective study in a four-level NICU examined term and near term MHD (150–169 mEq/L) newborns. In a novel hypernatremic dehydration treatment protocol, 49 newly diagnosed MHD patients were in group 1, while 54 previously treated control MHD patients were in group 2. Results 49 neonates received the novel treatment protocol (group 1), and data from 54 neonates were obtained from hospital records (group 2). Serum Na+ correction rate was significantly lower in group 1 compared to group 2, with a median serum Na+ level of 0.66 versus 1.05 mEq/L/h, p = 0.001. The proportion of patients who were treated with pure oral rehydration was significantly higher in group 1 compared to group 2 (67.3% vs 25.9%, p<0.001 ). Multiple regression analysis was performed to determine factors associated with use of intravenous rehydration: initial serum Na+ [odds ratio (OR):1.515, 95% confidence interval (CI) 1.17–1.94, p <0.001] and serum uric acid [OR: 1.495, 95% CI 1.092–2.00, p = 0.012] in model 2; belonging to Group 2 [OR: 28.267, 95% CI 10.321–53.69, p <0.001]; each additional delay in the day of postnatal admission [OR: 1.381, 95% CI 1.011–1.888, p = 0.043]; and initial serum Na+ [OR: 1.574, 95% CI 1.216–2.037, p = 0.001] in model 4 were significantly associated with intravenous rehydration. Conclusions Oral rehydration therapy offers slower sodium reduction and has a low treatment failure rate in MHD newborns. It can be the primary treatment approach, while intravenous therapy should be considered based on the patient’s overall clinical and biochemical status, not just initial sodium levels.
Intrapancreatic Peristaltic Duodenal Duplication Cyst; Presenting with Acute Pancreatitis and Intraabdominal Bleeding

Field: Medicine (Health Sciences)

Congenital anomalies and variations should be kept in mind when evaluating diseases in the pediatric patient group. A 12 years old girl presented with findings of acut abdomen. Clinical and laboratory data were consistent with acute pancreatitis. Imaging findings showed a peristaltic cystic tissue with a thick wall and central lumen in the head of the pancreas. In the operation, it was shown that this cystic lesion was associated with the accessory pancreatic duct and had no duodenal connection. In the pathology report, the presence of duodenal intestinal tissue compatible with a duplication cyst located in the head of the pancreas was proven. By sharing this rare case, keeping in mind the underlying congenital anomalies in any pathology in children and emphasizing the importance of ultrasonographic dynamic real-time examination in abdominal imaging.
Second-harmonic generation from mixed crystals of p-nitroaniline with substituted benzenes studied by the powder method

Field: Chemistry (Physical Sciences)

Second-harmonic generation (SHG) from mixed crystals of p-nitroaniline (p-NA) as guest and various substituted benzenes as host has been measured by the powder method with a 1064 nm YAG laser source. The SH intensities, which varied with crystallization conditions as well as host and mixing ratio, were as high as 100–189 × urea with p-dihydroxybenzene or p-dicyanobenzene as host. The SH intensity tends to increase with the size of the powdered crystals, implying a phase-matchable feature. The SHG activities were stable only at low (5 °C) temperature. It is speculated that epitaxial growth of p-NA crystals on the surface of host crystals would lead to an SHG-activity morphology.
Morphological diversities and ecozones of Ethiopian horse populations

Field: Veterinary (Health Sciences)

Using standard survey approaches, we carried out a nationwide survey to morphologically characterize and identify ecozones of Ethiopian horse populations. Accordingly, we explored one new feral horse population previously unreported and seven other distinct horse populations. A total of 17 selected morphological variables were recorded on 503 horses (293 stallions and 210 mares) that belong to ﬁve out of eight identiﬁed horse populations. Pair-wise multiple mean comparisons (PMMC) using one-way analysis of variance and multivariate analyses were performed separately for each sex and least-squares means was used in the case of aggregated sexes. Results of PMMC showed that there were signiﬁcant differences (P < 0.05) between the means for most of the variables recorded. Principal component analysis showed that height at wither, height at back, height at rump, body length, back length and \nbarrel length jointly account for about 80 percent of the variations. All squared Mahalanobis distance between populations were signiﬁcant (P < 0.01). The greatest phenotypic divergence was observed between Bale and Selale horse populations and the least phenotypic divergence was between Horro and Kafa populations. Canonical discriminant function analysis showed that 77.05 percent of individuals were correctly categorized into their respective populations. Moreover, cluster analysis based on squared Mahalanobis distances grouped the ﬁve measured Ethiopian horse populations into three major breed groups and ﬁve distinct horse populations.

PCA for gender estimation: which eigenvectors contribute?

Field: Computer Science (Physical Sciences)

A pruning schema is applied to multi-layer perceptron (MLP) gender classifier MLP uses eigenvector coefficients of the face space created by principal component analysis (PCA). We show that pruning improves the initial MLP performance by preserving the most effective input while eliminating most of the units and connections. Pruning is also used as a tool to monitor which eigenvectors contribute to gender estimation. In addition, by usage of FERET face database, we test the PCA approach on gender estimation task in a bigger setting than the previous experiments.
A colorimetric method for the determination of chloral hydrate

Field: Chemistry (Physical Sciences)

A specific colorimetric method for the determination of chloral hydrate is described. The method is based on the measurement of the pink colour formed when chloral hydrate is treated with 2-thiobarbituric acid. It is specific for chloral hydrate as no other related compounds tested, such as chloroform, trichloroacetic acid, trichloroethylene, carbon tetrachloride, 2,2-dichloroethanol and 1,1,2,2-tetrachloroethane, give any coloration with 2-thiobarbituric acid. The method is sensitive to concentrations as low as 50 µg ml–1 of chloral hydrate with a reproducibility of ±2 per cent.

Fluorescence lifetime sorting reveals tunable enzyme interactions within cytoplasmic condensates

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Ribonucleoprotein (RNP) condensates partition RNA and protein into multiple liquid phases. The multiphasic feature of condensate-enriched components creates experimental challenges for distinguishing membraneless condensate functions from the surrounding dilute phase. We combined fluorescence lifetime imaging microscopy (FLIM) with phasor plot filtering and segmentation to resolve condensates from the dilute phase. Condensate-specific lifetimes were used to track protein–protein interactions by measuring FLIM–Förster resonance energy transfer (FRET). We used condensate FLIM-FRET to evaluate whether mRNA decapping complex subunits can form decapping-competent interactions within P-bodies. Condensate FLIM-FRET revealed the presence of core subunit interactions within P-bodies under basal conditions and the disruption of interactions between the decapping enzyme (Dcp2) and a critical cofactor (Dcp1A) during oxidative stress. Our results show a context-dependent plasticity of the P-body interaction network, which can be rewired within minutes in response to stimuli. Together, our FLIM-based approaches provide investigators with an automated and rigorous method to uncover and track essential protein–protein interaction dynamics within RNP condensates in live cells.
Research in Practice: Preservice Teachers of the Deaf Action Research With DHH K–12 Learners and Self-Graphing

Field: Social Sciences (Social Sciences)

Abstract: When an instructional strategy lacks evidence of its effectiveness with certain learner groups, educators can conduct action research in their classroom to determine strategy effectiveness. In the present study, seven preservice teachers of the deaf (TODs) implemented self-graphing interventions with deaf/hard of hearing (DHH) learners to change target on- and off-task behaviors. Preservice teachers were master's-level candidates in a university teacher preparation program. DHH learners were 5–16 years old, attended general education classrooms at their local schools or schools for the deaf, and used multiple forms of communication/language. Candidates successfully completed ABAB design studies, and three candidates collected maintenance data after the interventions were withdrawn. They conducted their studies with high interobserver agreement. All DHH learners changed their target behavior when self-graphing was introduced. This study expands self-graphing evidence from high-incidence disability groups to a diverse group of DHH students.
