The behavior of Bernoulli shifts relative to their factors

Field: Mathematics (Physical Sciences)

We present numerous examples of ways that a Bernoulli shift can behave relative to a family of factors. This shows the similarities between the properties which collections of ergodic transformations can have and the behavior of a Bernoulli shift relative to a collection of its factors. For example, we construct a family of factors of a Bernoulli shift which have the same entropy, and any extension of one of these factors has more entropy, yet no two of these factors sit the same. This is the relative analog of Ornstein and Shields uncountable collection of nonisomorphic $K$ transformations of the same entropy. We are able to construct relative analogs of almost all the zero entropy counter-examples constructed by Rudolph (1979), as well as the $K$ counterexamples constructed by Hoffman (1997). This paper provides a solution to a problem posed by Ornstein (1975).
Asymptotic Normality of Simple Linear Rank Statistics Under Alternatives

Field: Mathematics (Physical Sciences)

Results of Chernoff-Savage (1958) and Govindarajulu-LeCam-Raghavachari (1966) are extended from the two-sample case to the general regression case and, simultaneously, the conditions on the scores-generating function are relaxed. The main results are stated in Section 2 and their proofs are given in Section 5. Sections 3 and 4 contain auxiliary propositions, on which the methods of the present paper are based. Section 6 includes a counterexample, showing that the theorem cannot be extended to discontinuous scores-generating functions.
Comparing Interracial Couples' Experience of Belonging at Multiethnic Churches and at Mono-Ethnic Churches

Field: Social Sciences (Social Sciences)

This project looked at the experience of 14 interracial couples who are connected with Fort Lee Gospel Church and a second multiethnic church. The question being addressed was whether or not a multiethnic church was better positioned to minister to an interracial couple than a mono-ethnic church. The questions were organized around the topic of general opposition, or failure to belong, experienced by interracial couples, how interracial couples experienced various churches, and how they experienced belonging in a multiethnic church. The experience of belonging was organized around five constructs: verbal affirmation, sense of commonality, feelings of inclusion, feelings of positive regard, and absence of prejudice or racism. On each of these constructs it was determined that an ethnically diverse church is a better setting for interracial couples to experience belonging. In addition, the transcultural experience of interracial couples uniquely equips them to help overcome racial differences that naturally occur within a multiethnic church.
(‘opyright 1993 by The Journal of Bone and Joint Surgery. Incorporated 674 THE JOURNAL OF BONE AND JOINT SURGERY Long-Term Complications after Total Knee Arthroplasty with or without Resurfacing of the Patella*

Field: Medicine (Health Sciences)

ABSTRACT: The long-term complications related to the patella were retrospectively evaluated for 891 knees (684 patients) that had had a total arthroplasty, with or without resurfacing of the patella, with use of an unconstrained, condylar, posterior-cruciate-preserving prosthesis. The study population comprised two groups of patients who were similar in size, age, sex distribu-tion, and diagnosis. One group (396 knees 1303 pa-tientsl) had had a total knee arthroplasty with patellar resurfacing and the other group (495 knees 1381 pa-tientsj) had had the same procedure without resurfac-ing. The average duration of follow-up was six and one-half years (range, two to fifteen years). The deci-sion to resurface the patella was based on subjective inspection of the articular surface and on assessment
Nonmagnetic Elinvar-Type Alloys in Mn-Ni System

Field: Materials Science (Physical Sciences)

Measurements of Young’s modulus and thermal expansion at −150°∼400°C, and of rigidity modulus and hardness at room temperature have been carried out with Mn-Ni alloys subject to various heat-treatments and cold-works. It has been found that Mn-10.15∼35.30%Ni alloys slow-cooled after heating at 950°C for 1 hr had clear minimum or maximum in Young’s modulus-temperature curves, and there anomalies correspond to antiferromagnetic Néel points or fcc\ ightleftarrowsfct martensitic transformation. The values of Young’s modulus at room temperature did not show a great difference among the annealed state, the cold-worked state, the reheated state after cold-working, the water-quenched state and the reheated state after water-quenching, but the difference being large in the γ phase and the mixture phase on the Mn side. Besides, a large minimum value of Young’s modulus was recognized near 18.5% of nickel contents. The temperature coefficient of Young’s modulus at room temperature was affected largely by heat-treatment, cold-working and alloy composition, and the temperature coefficient vs. composition curves exhibit a large maxima and minima in positive and negative signs. The highest positive temperature coefficient of Young’s modulus in the annealed state is +119.50×10−5 for the alloy containing 20.30%Ni, thus showing the Elinvar property. Further, the variation in rigidity modulus and its temperature coefficient by heat treatment, cold-working and alloy composition bears a close resemblance to that in Young’s modulus and its temperature coefficient. The hardness in the annealed state, the water-quenched state and the reheated state after water-quenching was generally lower than that in the cold-worked state and reheated state after cold-working.
Prevalence and Associated Factors of Post-COVID-19 Syndrome in a Brazilian Cohort after 3 and 6 Months of Hospital Discharge

Field: Medicine (Health Sciences)

(1) Objectives: To evaluate the frequency and factors associated with the Post-COVID-19 Syndrome (PCS) in COVID-19 survivors after 3 and 6 months of hospital discharge; (2) Methods: We conducted a cohort study with patients who were hospitalized with COVID-19 in a referral public hospital in Brasília, Federal District, Brazil. After 3 and 6 months of discharge, patients answered a questionnaire about PCS symptoms. Poisson regression with robust variance was used to estimate the crude and adjusted prevalence ratios (PR and aPR) of PCS. (3) Results: The prevalence of PCS was 81% and 61% after 3 and 6 months of hospital discharge, respectively. The main symptoms after 3 months of discharge were hair loss (44%), fatigue (42%), and memory loss (39%); while after 6 months, they were memory loss (29%) and fatigue (27%). In the multivariate analysis, the main factor associated with PCS was female gender (aPR): 1.28 (1.16–1.41) and 1.60 (1.34–1.90), 3 and 6 months after hospital discharge, respectively. Hypercholesterolemia was also associated with PCS after 3 months aPR of 1.15 (1.04–1.27). After 6 months of discharge, obesity [aPR: 1.22 (1.03–1.45)] and pronation [aPR: 1.15 (1.06–1.25)] were relevant associated factors. (4) Conclusions: The prevalence of PCS was high in COVID-19 survivors who had the moderate and severe forms of the disease. Memory loss was the most persistent symptom. Our data pointed to female gender, hypercholesterolemia, obesity, and pronation during hospitalization as relevant PCS-associated risk factors.
Effects of Gamma-Linolenic Acid Supplementation on Lipid Composition of Liver Microsomal Membranes

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

The effects of gamma-linolenic acid on essential fatty acid metabolism has been studied in fetuses from pregnant rats fed a zinc-deficient diet and in those from pregnant rats fed a balanced diet. Gamma-linolenic acid supplementation was in the form of evening primrose oil (EPO), and the study of lipid metabolism was carried out in liver microsomes. Pregnant rats were fed one of four diets: zinc-deficient (ZD), zinc-deficient+evening primrose oil (ZD+EPO), zinc-adequate (Control, C), and zinc adequate+evening primrose oil (C+EPO).In control groups (C and C+EPO) and deficient groups (ZD and ZD+EPO), gamma-linolenic acid supplementation had no effect on either zinc concentration in liver or Δ6 desaturation. All products of in vivo Δ6 desaturation were also not modified. Gamma-linolenic acid supplementation did not have much effect on essential fatty acid metabolism or on the distribution between n-6 and n-3 polyunsaturated fatty acid families. It was noticed, however, that the phosphatidylcholine level was enhanced and that the phosphatidylethanolamine level was decreased.The results indicate that in fetuses from pregnant rats fed a zinc-deficient diet the gamma-linolenic acid supplementation affects more the distribution of phospholipids in microsomal membranes than fatty acid profiles.
Antioxidant Property of an Ethanol Extract of the Stem of Opuntia ficus-indica var. Saboten

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

An ethanol extract of the stem of Opuntia ficus-indica var. saboten (OFS) was assessed to determine the mechanism(s) of its antioxidant activity. The ethanol extract exhibited a concentration-dependent inhibition of linoleic acid oxidation in a thiocyanate assay system. In addition, the OFS extract showed dose-dependent free-radical scavenging activity, including DPPH radicals, superoxide anions (O(2)(*-)), and hydroxyl radicals (*OH), using different assay systems. The OFS ethanol extract was also found to be effective in protecting plasmid DNA against the strand breakage induced by hydroxyl radicals in a Fenton's reaction mixture. Furthermore, the extract showed significant (p < 0.01) dose-dependent protection of mouse splenocytes against glucose oxidase-mediated cytotoxicity. Finally, the OFS extract was characterized as containing a high amount of phenolics (180.3 mg/g), which might be the active compounds responsible for the antioxidant properties of the OFS extract.
An unusual case: Ruptured and infected primary muscle cystic echinococcosis

Field: Medicine (Health Sciences)

Abstract There are few case reports of primary muscle cystic echinococcosis in which a hot abscess developed at the site of the cyst following its perforation. Here, the author presents a 23-year-old female with a hydatid cyst of more than 15 years’ duration in her right quadriceps muscle. The cyst did not cause any complaints for years and grew very slowly, but eventually became infected and perforated. A large hot abscess was formed at its site. The patient was managed successfully by surgical and medical treatments. She was assessed carefully for clinical, radiological, surgical and histopathological findings. Investigations were made to differentiate the condition from classical hot abscesses and other soft tissue masses. In T1-and T2-weighted magnetic resonance images, a hypointense membranous structure (the perforated rim) within the mass of the lesion was significant for its differential diagnosis. In conclusion, especially in endemic regions, magnetic resonance imaging is a valuable tool in differentiating soft tissue cystic echinococcosis in the presence of infected and rapidly enlarging masses after long periods of dormancy.
Multi-sensor data fusion in sensor-based control: Application to multi-camera visual servoing

Field: Engineering (Physical Sciences)

A low-level sensor fusion scheme is presented for the positioning of a multi-sensor robot. This non-hierarchical framework can be used for robot arms or other velocity-controlled robots, and is part of the task function approach. A stability analysis is presented for the general case, then several control laws illustrate the versatility of the framework. This approach is applied to the multi-camera eye-in-hand/eye-to-hand configuration in visual servoing. Experimental results point out the feasibility and the effectiveness of the proposed control laws. Mono-camera and multi-camera schemes are compared, showing that the proposed sensor fusion scheme improves the behavior of a robot arm.
Gamification of Open Inquiry-based Learning of Blockchain Technologies

Field: Computer Science (Physical Sciences)

Inquiry-based Learning is an efficient learning method. This method is applied in many science courses. It is a research-oriented method which awakens personal curiosity of learners. Learners are motivated intrinsically, and they learn by research. Wide research areas can be investigated using Inquiry-based Learning. It can be applied to all learning areas. In the literature, Inquiry-based Learning is applied to science education. In this paper, Inquiry-based Learning is applied to a software engineering course. The application is novel because the area is a non-science area. Cryptocurrencies, which are applications of blockchain technologies, are selected as the research area. Research is done by students freely. Results of research are combined and shared among students. Students are assessed. Inquiry-based Learning is applied in a least structured way. In other words, open Inquiry-based Learning is applied. To empower it, gamification is used. A methodology for open Inquiry-based Learning is presented. The effect of gamification is measured.
Psychometric Validation of the Derogais' Brief Simptom Inventory (BSI)

Field: Psychology (Social Sciences)

Brief Simptom Inventory (BSI; Derogatis 1993) is a 53-item self-report inventory designed to assess current level of psychological symptoms and distress. To evaluate the applicability of this measure in croatian conditions, metric caracteristics have been verified and compared to norms. The BSI was administrated to 500 participants from general population and 159 persons who had traumatic experience, but never asked for professional help. Percentages symptomatic in general population were larger then american norms, but smaller then percetages of traumatized persons. Traumatised persons had statisticaly significant greater results on all dimensions and global indicies than general population. On separate dimensions, there was significant difference between the sexes in the general population which was, as expected, in favor of women. Compared with american adult nonpatient norms (Derogatis, 1993), both traumatised persons and members of general population scored higher. BSI indicated good sensitivity in consideration of the fact that it better discriminated the participants which experienced greater levels of distress. Discriminative validity of all of the items was good. Reliability of the whole BSI was very high and internal consistancy on separate dimensions ranged from A�Â±= .83 to A�Â±= .92 in the traumatised persons group and from A�Â±= .69 to A�Â±= .84 in general population. Principal components analysis revealed one dominant component that accounted for large majority of the variance and which had substantial loadings on all of the items in both samples. Unidimensionality of the BSI was corroborated by the homogenity of the Inventory and significant corelations among the dimensions. These findings indicate that the composite score on the Brief Symprom Inventory is a good indicator of distress and that it reflects the degree but not the precise nature of the psychopathology.
The Effect of Rhodamine B on the Cerebellum and Brainstem Tissue of Rattus Norvegicus

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Background Rhodamine B is a component of xenobiotic substance metabolized by cytochrome P450 in the body to produce free radicals, which affects the activity of Superoxidase Dismutase (SOD), thereby, leading to oxidative stress, injury, increase in cell apoptosis and brainstem. This study aims to determine the effect of Rhodamine B on BAX and BCL-2 in the cerebellum and brainstem tissue of Rattus norvegicus. Design and methods The True Experimental Design was used to carry out a post-test examination on the control group of twenty-eight Wistar female Rattus norvegicus mice between the ages of 10-12 weeks. Then, samples were categorized into 4 groups in body weight doses of 4.5 mg/200g, 9 mg/200g, and 18 mg/200g. They were administrated with Rhodamine B personde for 36 days. Results The results showed that Rhodamine B had a direct and indirect effect on BAX and BCL-2 expressions, respectively, in the cerebellum tissue and wistar strain of Rattus norvegicus. In addition, the positive path coefficient of BAX expression has a positive effect on BCL-2. This means that an increase in BAX has a direct impact on decreasing BCL-2 expression in cerebellum tissue and brainstem of Rattus norvegicus wistar strain along with an increased dose of Rhodamine B. Conclusions In conclusion, Rhodamine B tends to increase BAX expression which directly decreases BCL-2 in Cerebellum tissue and Brainstem in Rattus norvegicus along with increasing doses.
Security Through Deception

Field: Computer Science (Physical Sciences)

ABSTRACT For each layer of information security there is a number of techniques and tools that can be used to ensure information superiority. Indeed some experts would argue that you cannot have the former without the latter. In today's technological & interconnected world, however, information superiority is very hard to achieve and almost impossible to maintain. This paper will argue that the art of deception is a reliable and cost effective technique that can assure the security of an infrastructure. The paper will conclude by presenting a technical solution of the above statement.
Rif1 regulates the fate of telomere entanglements during M-phase

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

The protection of chromosome ends, and in turn genome stability, is intimately linked with the ability of telomeres to replicate and segregate with high fidelity. It has been shown previously that Taz1, the fission yeast ortholog of mammalian TRF1 and TRF2, is critical for promoting passage of the replication fork through telomere sequences. Deletion of taz1+ results in stalled telomeric replication forks that fail to resume. These defective replication intermediates lead to telomere entanglements that fail to be resolved in mitosis at cold temperatures, leading taz1Δ cells to be cold sensitive. It is not yet known exactly what entanglements are, why they occur at cold temperatures, and how (or if) they are resolved. In this thesis telomere entanglements are further investigated. We found that in taz1∆ cells grown in the cold, entangled telomeres can be visualized as DNA masses persisting between separating sister chromatids during M-phase. We have observed sister chromatid masses which remain connected either by histone bound DNA resulting in aberrant chromosome segregation morphologies, or by ssDNA coated with Rad11RPA and Rad22Rad52. The former was observed to be highly dangerous, the latter can be processed and cells can continue to the next cell cycle. Rif1, a conserved replication/repair protein sparked our interest when we observed that rif1+ deletion suppresses taz1Δ cold sensitivity. However, the function of Rif1 was a mystery; revealing the role of Rif1 in cells lacking taz1+ formed the next part of this thesis. We have found that Rif1 acts in removal of telomeric entanglements rather than at the fork-stalling events that generate them. Although Rif1 is reported to bind telomeres in a Taz1-dependent manner, we observe Rif1 at the mid-zone during anaphase in wild type and taz1∆ cells, associated to thin DNA stretches. Artificially recruiting Rif1 to a taz1∆ telomere is lethal in the cold, indicating that the departure of Rif1 from the telomere is essential for viability and presumably for entanglement resolution. We propose a newly identified role for Rif1 in regulating the resolution of entangled DNA during M-phase.

ARITHMETIC IN EXCEL: MICROSOFT'S SILENCE ON GLOBAL EDUCATION

Field: Computer Science (Physical Sciences)

Licensed Microsoft Excel is one of the most widely used tools in the world for calculations, financial analysis, and data manipulation. Despite its apparent precision, Excel is not infallible. There are situations where it can present arithmetic errors, especially due to internal limitations of numerical representation, rounding, and the peculiarities of its formulas. Understanding these factors is essential to avoid flawed conclusions in critical spreadsheets. Using a practical example, this article discusses the pedagogical implications of a multiplication error in Excel, highlighting how recurring inaccuracies can compromise mathematics education. Such flaws can seriously harm data analysis, leading to incorrect interpretations and decisions. Excel uses floating-point representation based on the IEEE 754 standard to store decimal numbers, which can prevent the accuracy of certain values. Although this phenomenon is not exclusive to Excel, its widespread adoption makes the effects more noticeable. For example, operations like 0.1 * 0.2 can result in 0.20000000000000004 instead of 0.2 — a typical inaccuracy of floating-point arithmetic. Although generally not visible in the standard interface, these flaws can affect logical comparisons and chained calculations. In the pedagogical context, similar errors in multiplication operations can compromise the teaching of fundamental mathematical concepts. Errors derived from floating-point representation can occur in various software. In the case of Excel, its widespread adoption and lack of transparency make the impact of these problems even more severe, which accentuates the pedagogical risks of the uncritical use of a tool widely adopted as a reference by students and professionals.
