Validated measures of semantic knowledge and semantic control: normative data from young and older adults for more than 300 semantic judgements

Recent studies suggest that knowledge representations and control processes are the two key components underpinning semantic cognition, and are also crucial indicators of the shifting cognitive architecture of semantics in later life. Although there are many standardized assessments that provide measures of the quantity of semantic knowledge participants possess, normative data for tasks that probe semantic control processes are not yet available. Here, we present normative data from more than 200 young and older participants on a large set of stimuli in two semantic tasks, which probe controlled semantic processing (feature-matching task) and semantic knowledge (synonym judgement task). We verify the validity of our norms by replicating established age- and psycholinguistic-property-related effects on semantic cognition. Specifically, we find that older people have more detailed semantic knowledge than young people but have less effective semantic control processes. We also obtain expected effects of word frequency and inter-item competition on performance. Parametrically varied difficulty levels are defined for half of the stimuli based on participants' behavioural performance, allowing future studies to produce customized sets of experimental stimuli based on our norms. We provide all stimuli, data and code used for analysis, in the hope that they are useful to other researchers.
Clinical and Bacteriologic Characteristics of Six Cases of Bifidobacterium breve Bacteremia Due to Probiotic Administration in the Neonatal Intensive Care Unit

Background: Bifidobacterium breve is widely used as a probiotic in preterm infants and children with congenital surgical conditions, however, some cases of probiotics-induced bacteremia have been reported recently. Objectives: To examine the clinical and bacteriologic features of Bifidobacterium breve bacteremia caused by a probiotic (BBG-01) in term and preterm infants. Methods: We included 298 patients who were admitted to the neonatal intensive care unit of Miyagi Children’s Hospital and were given BBG-01 as a probiotic within the period June 2014 to February 2019. We experienced six cases of B. breve bacteremia and assessed their features retrospectively. Results: The incidence rate of B. breve bacteremia in our hospital was 2% (6/298), higher than reported previously. The median age at onset, corrected age, and weight of the patients was 8 days (range: 5–27 days), 35 weeks (range: 26–39 weeks), and 1,940 g (range: 369–2734 g), respectively. The bacteremia triggers were gastrointestinal perforations in two cases, food protein-induced enterocolitis syndrome in two cases, adhesive ileus in one case, ileal volvulus in one case, and aspiration pneumonia following esophageal atresia repair in one case. B. breve was detected on blood cultures after a median of 5 days 13 hours (range: 4 days 18 hours–9 days 13 hours). No patient demonstrated serious symptoms, such as septic shock. All patients received antibiotics and recovered without any sequelae. Conclusions: Ileus and intestinal mucosal damage, such as enteritis, can cause B. breve bacteremia. The incidence of B. breve bacteremia may be higher than reported previously and detection via culture may require a longer time than typically needed for more common bacteria. It is associated with a good prognosis.
Addressing the Theoretical and Experimental Aspects of Low-Dimensional-Materials-Based FET Immunosensors: A Review

Electrochemical immunosensors (EI) have been widely investigated in the last several years. Among them, immunosensors based on low-dimensional materials (LDM) stand out, as they could provide a substantial gain in fabricating point-of-care devices, paving the way for fast, precise, and sensitive diagnosis of numerous severe illnesses. The high surface area available in LDMs makes it possible to immobilize a high density of bioreceptors, improving the sensitivity in biorecognition events between antibodies and antigens. If on the one hand, many works present promising results in using LDMs as a sensing material in EIs, on the other hand, very few of them discuss the fundamental interactions involved at the interfaces. Understanding the fundamental Chemistry and Physics of the interactions between the surface of LDMs and the bioreceptors, and how the operating conditions and biorecognition events affect those interactions, is vital when proposing new devices. Here, we present a review of recent works on EIs, focusing on devices that use LDMs (1D and 2D) as the sensing substrate. To do so, we highlight both experimental and theoretical aspects, bringing to light the fundamental aspects of the main interactions occurring at the interfaces and the operating mechanisms in which the detections are based.
Comparing Concrete and Virtual Manipulatives to Teach Algebra to Middle School Students with Disabilities

ABSTRACT Manipulatives are an effective mathematical tool to support students with disabilities in the area of mathematics. Yet, there remain inconsistencies in terms of which type – concrete or virtual – is more effective for students with disabilities working on algebra related content and which type is preferred by students. The researchers used an alternating treatment single case research design to compare the effectiveness of each type of manipulative in terms of students’ accuracy and independence when using the tools. Results indicate both types of manipulatives were effective in terms of accuracy no notable differences when comparing independence. However, when reviewing social validity interview data, all three students preferred virtual algebra tiles.
Success Rate of Endoscopic Third Ventriculostomy (ETV) in Non-Communicating Hydrocephalus in Pediatric Age Group

Objective: To evaluate success rate of the endoscopic third Ventriculostomy (ETV) in non-communicating type of hydrocephalus in pediatric age group. Material and Methods: This study was carried in the department of neurosurgery at Liaquat university hospital, Jamshoro in which an endoscopic third Ventriculostomy procedure was performed in patients (n = 55) with non-communicating hydrocephalus from October 2016 to April 2017. Post-operative follow-up was done on the 15th day post-operative to assess clinical and radiological improvement. Results: 55 patients were included in this study, 26 (47.27%) males and 29 (52.73%) females. The mean age was 3.96 years. The most common etiology was aqueductal stenosis 28 (50.90%) patients followed by posterior fossa tumors in 18 (32.72%) patients. The operative technique was successful in 41 (74.55%) patients. Out of 41 successful patients, 34 (82.92%) patients had clinical as well as radiological improvement whereas 7 (17.07%) patients had clinical improvement only. Conclusion: The success rate of ETV was 74.55% in the non-communicating hydrocephalus in the pediatric age group in our study. Endoscopic third Ventriculostomy is an effective treatment for non-Communicating hydrocephalus in pediatric age groups by diversion of CSF intracranially. This procedure provides shunt freedom and can be used alternative to shunts in pediatric age groups with non-communicating hydrocephalus.
Effect of the nature of counterion on the micellar properties of cationic surfactants: a conductometric study

ABSTRACT Interaction of cationic surfactants, tetradecyltrimethylammium bromide (TTAB) and tetradecyltrimethylammonium chloride (TTAC) with anionic dye, tartrazine in aqueous solution has been investigated employing conductometric technique. The free energy of transfer of hydrophobic chain, , surface contribution, and their transfer values, and , free energy, , enthalpy, , and entropy, of micellisation have been calculated. A marked decrease in the critical micelle concentration for TTAB compared to TTAC indicates dramatic role of the smaller counterion Br− over the bigger counterion Cl−. Formation of dye–surfactant ion-pairs which behave as nonionic surfactant has been proposed. Higher negative and positive values for TTAB than TTAC are attributed to difference in the size and nature of the counterions Br− and Cl−. Negative and values clearly suggest that micellisation of TTAB and TTAC is thermodynamically spontaneous and exothermic in nature. As ), it suggests that the process of micellisation is entropy dominated for the two surfactants.
Exploring Grade 8 Students’ Errors When Learning About the Surface Area of Prisms

The calculation of the total surface area of prisms forms part of the Mathematics curriculum in South Africa. This paper explores Grade 8 students’ errors when learning about the surface area of prisms. The study was guided by the interpretive paradigm and adopted a qualitative approach in a form of a case study design. Data from diagnostic test’s responses were analysed using Newman’s theory of error analysis. The sample comprised 18 purposively selected Grade 8 students. The study revealed that students committed these errors: failure to differentiate 2-Dimensionals from 3-Dimensionals; calculated the Total Surface Area as the perimeter of polygons; used volume of prisms formula for Total Surface Area; and misunderstanding of mathematical terminology related to surface area of prisms. The study recommends the use of students’ errors as tools to guide in designing the intervention activities to remedy misconceptions that students hold when learning about the surface area of prisms.
Age, Gender Pattern and Liver Function Markers in Hepatitis B and C Seropositive Participants Attending a Health Facility in Yaba-Lagos, Nigeria

Background: Individuals with sero-positivity for Hepatitis B and C have been reported. Most seropositive individuals appear healthy. Liver function markers such as AST, ALT, ALP, Bilirubin and total protein levels are markers for assessing liver impairment. This study (i)assessed seroprevalence of HBV, HCV and both HBV and HCV (ii) HBV and or HCV seropositivity and age or gender, (iii) assess gender and liver function markers and (iv) update data on liver function and simple diagnostic markers. Materials and Methods: This was a prospective, cross sectional study of asymptomatic individuals presenting at the Clinical Diagnostic Laboratory of Nigerian Institute of Medical Research (NIMR), Yaba, Lagos, Nigeria from January 2018 to August 2020. Markers of liver function were investigated on hepatitis B and or C sero-positive and negative participants using TC Matrix Chemistry analyser (Teco Diagnostics, USA) and Biobase reagent Kits. Data were analyzed using descriptive and inferential statistics. Results: Out of 475 participants, 60.4% were males and 39.6% females. 53% of males and 32.5% of females were sero-positive for HBV while 32.5% of males and 14.5% of females were sero-positive for HCV. 75.3% and 76.1% of Age group 20 - 40 years were sero-positive for Hepatitis B and C respectively. Mean AST levels of 17.49 ± 13.69, 33.46 ± 93.42 and 19.82 ± 12.54 respectively among those sero-positive for HBV, HCV, and both HBV and HCV. Mean ALT levels of 17.68 ± 14.32, 40.26 ± 13.86 and 20.04 ± 12.78 respectively for HBV, HCV and both HBV and HCV sero-positive cases. Mean ALP levels were 77.52 ± 34.0 for HBV sero-positive cases, 82.04 ± 38.45 in HCV and 77.95 ± 30.48 in both HBV and HCV sero-positive cases. Mean Total Bilirubin levels of HBV, HCV and both HBV and HCV sero-positive cases were 13.25 ± 14.52, 14.98 ± 20.74, 10.58 ± 4.91 respectively while Mean Total protein levels were 77.24 ± 6.27 in HBV, 77.87 ± 5.56 in HCV and 77.0 ± 5.99 in both HBV and HCV sero-positive cases. ALP, bilirubin and total protein were all within normal reference values in HBV, HCV and HBV/HCV dual infections. AST and ALT values were significantly elevated in HCV seropositivity compared to HBV single and HBV/BCV dual seropositivity. Conclusion: 30% prevalence of HBV, HCV and both HBV and HCV were observed. Age 20 - 40 years was significantly higher in seropositivity for hepatitis B, C and B and C dual seropositivity. More males than females showed seropositivity for hepatitis B and C. There was no significant difference between gender and liver function markers. AST and ALT remain reliable markers of liver function.
Collective dynamics of liquid aluminium probed by Inelastic X-ray Scattering

An inelastic X-ray scattering experiment has been performed in liquid aluminum with the purpose of studying the collective excitations at wavevectors below the first sharp diffraction peak. The high instrumental resolution (up to 1.5 meV) allows an accurate investigation of the dynamical processes in this liquid metal on the basis of a generalized hydrodynamics framework. The outcoming results confirm the presence of a viscosity relaxation scenario ruled by a two timescale mechanism, as recently found in liquid lithium.
Charge transport mechanism in copper phthalocyanine thin films with and without traps

We investigate the charge transport mechanism in copper phthalocyanine thin films with and without traps. Previously, charge transport in polycrystalline thin films has been widely described by the multiple trapping and release (MTR) model, without emphasizing the origin of the traps. In this work, polycrystalline organic thin films with and without traps have been grown by engineering different growth conditions. We find that the density of interface states at the grain boundaries can decide the mechanism of charge transport in organic thin films and completely different charge transport mechanisms can be observed in thin films with and without traps.
Gemini Principles-Based Digital Twin Maturity Model for Asset Management

Various maturity models have been developed for understanding the diffusion and implementation of new technologies/approaches. However, we find that existing maturity models fail to understand the implementation of emerging digital twin technique comprehensively and quantitatively. This research aims to develop an innovative maturity model for measuring digital twin maturity for asset management. This model is established based on Gemini Principles to form a systematic view of digital twin development and implementation. Within this maturity model, three main dimensions consisting of nine sub-dimensions have been defined firstly, which were further articulated by 27 rubrics. Then, a questionnaire survey with 40 experts involved is designed and conducted to examine these rubrics. This model is finally illustrated and validated by two case studies in Shanghai and Cambridge. The results show that the digital twin maturity model is effective to qualitatively evaluate and compare the maturity of digital twin implementation at the project level. It can also initiate the roadmap for improving the performance of digital twin supported asset management.
Oral Health In Patients With COVID-19: A Literature Review

This article reviews the most common oral health problems, which could be associated with coronavirus disease 2019 (COVID-19). Several reports were published, which described various oral manifestations of COVID, including dysgeusia, petechiae, candidiasis, traumatic ulcers, herpesvirus infection, geographic tongue, thrush like ulcers, among others. Alterations of smell and taste seem to be the most common manifestations of COVID in the orofacial area, which could be directly related to the effect of the virus. Other oral conditions seem to be secondary to the decrease of host defense, or else caused by the drugs and intensive care used in the treatment of COVID-19.
Disagreement and Agonistic Chance in Peer Review

The purpose of grant peer review is to identify the most excellent and promising research projects. However, sociologists of science and STS scholars have shown that peer review tends to promote solid low-risk projects at the expense of more original and innovative projects that often come with higher risk. It has also been shown that the review process is affected by significant measures of chance. Against this background, the aim of this study is to theorize the notions of academic judgment and agonistic chance, and to present and analyze situations in which expert reviewers are faced with the challenge of trying to decide which grant proposals to select when there is strong disagreement. The empirical analysis is based on ethnographic observations of ten panel groups at the Swedish Research Council in the areas of natural and engineering sciences. By focusing on disagreement, the study provides a more in-depth understanding of how agonistic chance creeps into the peer review process and becomes part of the consensus that is created.

This paper examines the impact of risk willingness and opportunity recognition on business owners’ performance in Sabah, Malaysia. The paper adopts non-probability sampling, known as a purposive sampling method, in selecting business owners. A total of 600 surveys using self-conducted questionnaires structured on a 7-point Likert scale is distributed, and subsequently, 525 questionnaires are returned. The EAO dimensions assessed in the paper are risk willingness and opportunity recognition. Data collected are analysed using the SEM-PLS technique through the SmartPLS 3.3. 2 software. The study found a positive effect of risk willingness and opportunity recognition on the business owners’ performance. Accordingly, this paper’s theoretical and practical implication supports some of the previous findings and arguments that EAO plays an essential role in influencing micro-business owners’ performance.
Tame Algebras Have Dense g-Vector Fans

The $\textbf{g}$-vector fan of a finite-dimensional algebra is a fan whose rays are the $\textbf{g}$-vectors of its two-term presilting objects. We prove that the $\textbf{g}$-vector fan of a tame algebra is dense. We then apply this result to obtain a near classification of quivers for which the closure of the cluster $\textbf{g}$-vector fan is dense or is a half-space, using the additive categorification of cluster algebras by means of Jacobian algebras. As another application, we prove that for quivers with potentials arising from once-punctured closed surfaces, the stability and cluster scattering diagrams only differ by wall-crossing functions on the walls contained in a separating hyperplane. The appendix is devoted to the construction of truncated twist functors and their adjoints.

Likewise, the characteristics of the majority of fitness center members are individuals who feel quite happy with the situation and conditions provided by the manager, thereby indicating that the Service Quality at the current Fitness Center business in East Java has not been able to encourage an increase in customer delight. The results of this study also show that Service Quality has a significant effect on Customer Loyality, thus Service Quality at the current Fitness Center business in East Java can encourage the increase in Customer Loyality. Given the large role of service quality on customer loyalty, it is recommended that companies always maintain and improve service quality at the Fitness Center business in East Java.
Statistical analysis of maximum runoff of the Southern Buh River using the method of ‘Indicators of Hydrologic Alteration’

Knowledge of maximum river runoff trends is of great practical importance, especially for design and operation of hydraulic structures. This article presents the results of the research of the Southern Buh River's maximum runoff. The water of the river is widely used for hydropower engineering, industrial and municipal water supply, agriculture, irrigation, shipping, tourism etc. The research of the maximum runoff was based on the Indicators of Hydrologic Alteration (IHA) method which is widely used in the whole world. This method enables calculation of quantitative statistical characteristics of rivers', lakes', reservoirs' runoff and determination of the degree of their hydrological regime changes. The IHA is used for water bodies having natural or regulated runoff. However, the IHA method was not widely used in Ukraine before. The purpose of this publication is using the Indicators of Hydrologic Alterations method in order to study the characteristics of maximum runoff and their changes along the Southern Buh River. The research was carried out based on the data of observations at 5 gauge stations located along the Southern Buh River. The research uses the mean daily discharges that has been recorded since the beginning of observations up to 2018 and 2019 inclusive. The river's runoff at each of gauge stations was divided into five components: "Extremely low runoff", "Low runoff", "High runoff pulses", "Small floods", "Large floods". This made it possible to separate three classes of high (maximum) runoff, for which the IHA statistics were calculated, from the total runoff. It was discovered that the long-term high runoff changes differed in each of its three components, although they had general trends. The most significant changes were found for large floods, with no significant changes found for high runoff pulses. General trends of high runoff showed that over time the values of maximum discharges tend to decrease, with the increasing duration of high runoff periods. The values of the main statistical indicators of high runoff gradually increase from the river's source to its mouth, which fully corresponds to the physical and geographical conditions of its formation. Nevertheless, some features of high runoff were still found. Thus small floods and high runoff pulses have the largest duration in the upper reach of the river. On average, the Southern Buh River experiences large floods once in every 10 years, small floods - once in every 2 years, high runoff pulses - 4-8 times a year in its upper reach and 9-14 times a year in its middle reach.
Low-Power High-Linearity Mixer-First Receiver Using Implicit Capacitive Stacking With 3× Voltage Gain

In this article, we present a passive mixer-first receiver front end providing a low-power integrated solution for high interference robustness in radios targeting Internet-of-Things (IoT) applications. The receiver front end employs a novel N-path filter/mixer, a linear baseband amplifier, and a step-up transformer to realize sub-6-dB NF and >20-dBm OB-IIP3 concurrently. The proposed N-path filter/mixer exploits an implicit capacitive stacking principle to achieve passive voltage gain of 3 during down-conversion and high out-of-band linearity simultaneously while using at least 2 $\times $ less total capacitance for the same RF bandwidth compared to a conventional switch-capacitor N-path filter. Fabricated in 22-nm complementary metal–oxide–semiconductor (CMOS) fully depleted silicon on insulator (FDSOI), the receiver prototype—including a 2:6 transformer—occupies only 0.2 mm2 of active area. Operating in the frequency range of 1.8–2.8 GHz, the front end provides a 45–47-dB conversion gain and a baseband bandwidth of 2 MHz. Due to passive voltage gain in the filter/mixer and transformer, the implemented front end consumes only 1.7–2.5 mW of power to achieve < 6-dB NF, ~24/60/1 dBm out-of-band IIP3/IIP2/B1dB, respectively.
