Controllers to Chase a High-Speed Evader Using a Pursuer with Variable Speed

This paper proposes a chasing controller to enable a pursuer to chase a high-speed evader such that the relative distance between the evader and the pursuer monotonically decreases as time passes. Our controller is designed to assure that the angular rate of Line-of-Sight joining the pair (the pursuer and the evader) is exactly zero at all time indexes. Assuming that the pursuee can readily observe optical flow, but only poorly detect looming, this pursuer’s movement is hardly detected by the pursuee. Consider the terminal phase when the pursuer is sufficiently close to the evader. As we slow down the relative speed of the pursuer with respect to the evader, we can reduce the probability of missing the high-speed evader. Thus, our strategy is to make the pursuer decrease its speed in the terminal phase, while ensuring that the distance between the evader and the pursuer monotonically decreases as time passes. The performance of our controller is verified utilizing MATLAB simulations.

Inbreeding depression affects pollen performance in <i>Cucurbita texana</i>

Abstract Most studies of the effects of inbreeding focus on vegetative vigor and reproductive output through the female (fruit and seed) function. This study not only examines the effects of inbreeding on the female function but it also examines the effects of inbreeding on pollen performance both in vitro and in vivo . This study used Cucurbita texana , a wild gourd, and was performed under field conditions. In vivo performance was assessed by placing equal amounts of pollen from either the inbred or outcrossed plants onto a stigma together with pollen from a tester line. As with other studies, we found that outcrossed plants had greater reproductive output (male flowers and fruits) than plants produced from self pollinations. Unlike most studies of inbreeding depression, which mostly ignore the male function of plants, we also found that the pollen produced by outcrossed plants had faster pollen tube growth in vitro than the pollen produced on selfed plants. Moreover, pollen from selfed plants sired significantly fewer seeds than pollen from outcrossed plants under conditions of pollen competition (i.e. the number of pollen grains deposited onto the stigmas was larger than the number of available ovules). These findings indicate that inbreeding affects the performance of the resulting sporophytic generation and the microgametophytes they produce.

Pulsed EPR experiments on radical pairs in photosynthesis: Comparison of the donor‐acceptor distances in photosystem I and bacterial reaction centers

Abstract Pulsed EPR spectroscopy is applied to the radical pairs P Q in bacterial reaction centers of Rhodobacter sphaeroides R‐26 and P A in photosystem I from Synechococcus elongatus . For both radical pairs an out‐of‐phase echo was observed showing a deep modulation as a function of the spacing between the two microwave pulses. From the modulation frequency the dipolar and isotropic couplings between the radical pair spins were derived. For the bacterial reaction centers a dipolar coupling of D ≈︁ −121 μT was obtained, resulting in a distance of about 28.4 Å between the electron spins of the radical pair. This value is in good agreement with the distance derived from the x‐ray structure of Rhodobacter sphaeroides R‐26. From the faster modulation in the PS I sample we obtained a dipolar coupling of D ≈︁ −170μT, indicating a distance of 25.4 Å between the primary donor P 700 and the acceptor quinone A 1 . For both radical pairs, only a small isotropic coupling of J ≈︁ 1 μT, consistent with transient EPR spectra, was found.

Optimizing Bipartite Matching with Interleaved and Injective Mappings: Implementing and Evaluating the k-Swap Heuristic

Bipartite matching problems play a crucial role in various software engineering tools, including resource allocation and task assignment. In this paper, we address a specific variant of the bipartite matching problem, called the Double Assignment Problem (DAP), focusing on the allocation of machines to workers in a production environment. The objective is to maximize the number of worker-machine associations, subject to a second, orthogonal matching problem: associating some worker W to a machine M implies that the (ordered) list of servers employed by M are dedicated to the respective programs used by the worker W. Since DAP is, in general, NP-hard, we introduce a heuristic that quickly approximates candidate results. The heuristic is called k-swap stability and has originally been formalized to tackle a specific DAP instance arising in the niche field of anti-unification. We extend the definition to our more general setting and give promising preliminary results obtained by applying our k-swap implementation on a testbed of examples.

Normal Pregnancies after Treatment of Hyperprolactinemia with Bromoergocryptine, Despite Suspected Pituitary Tumors

Bromocryptine treatment was administered to 15 patients with amenorrhea and galactorrhea (AG) and to 1 patient with amenorrhea. All of them had increased plasma PRL levels. Of these 16 patients, 4 had a normal sella turcica (ST; group STO), 4 had a slight enlargement (group ST+), and 7 had a clear enlargement of ST (ST++) but no evidence of suprasellar extension. Ovulation was restored in 15 patients by bromocryptine treatment only. In one patient, ovulation resumed only after human pituitary gonadotropin treatment in combination with bromocryptine. There was no correlation between basal prolactinemia, PRL stimulability or suppressibility, the size of ST, or the efficiency of bromocryptine treatment. Every patient with normal LH response to either LRH or clomiphene or both resumed ovulation. Ovulation resumed in 3 patients among the 4 with abnormal LH response to either LRH or clomiphene or both. Among the 14 who desired pregnancy, 13 became pregnant. To date, 12 patients (ST++, 5; ST+, 3; STO, 4) have delivered normal babies. The courses of pregnancy were normal. During pregnancy, no change of ST was noted on lateral and frontal skull x-ray performed in every patient at trimonthly intervals. There was no change in the sellar index in 10 patients after pregnancy, as compared to the pretreatment status. In the presence of a pituitary adenoma or in patients with hyperprolactinemia and amenorrhea and galactorrhea, bromocryptine treatment may cure sterility without pituitary complication during pregnancy.

Monitoring and Tracking the Spread of SARS-CoV-2 in Asturias, Spain

Mutational analysis of SARS-CoV-2 can quantify their relative importance over time, enable the dominant mutations to be identified and facilitate near real-time detection, comparison, and tracking of evolving variants. Collected samples in Asturias an autonomous community of Spain with a large aged population, and high levels of migration and tourism was monitored and tracked from its beginning in February 2020 until its decline and stabilization in August 2021, were characterized using whole genomic sequence and single nucleotide polymorphism. Data held in the GISAID database was analyzed to establish patterns in the appearance and persistence of SARS-CoV-2 strains. Only 138 non-synonymous mutations occurring in more than 1% of the population of SARS-CoV-2 were found, identifying 10 major variants worldwide (7 arose before January 2021), 19 regional and 1 local. In Asturias only 17 different variants were found. After vaccination, no further regional majority variants were found. Only half of the defined variants circulated and no new variants were generated, indicating that infection control measures (fast diagnosis, prevention measures and vaccination) were efficient.

Intra-examiner reliability of measurements of ankle range of motion using a modified inclinometer: a pilot study.

A modified inclinometer was designed for measuring total ankle range of motion (ROM) in the standing position for a large future study. The purpose of this pilot study was to assess the intra-examiner reliability of this new device in order to see if the examiner would be able to produce equally reliable measurements with this instrument as with a routinely used goniometer. Nineteen young healthy individuals took part in the pilot. The same examiner took the ROM measurements using both devices twice on the same day and one further time 2 or 3 days later. Test-retest reliability was measured using the intraclass correlation coefficient (ICC). The ICC values were 0.86 (95% CI=[0.67; 0.94]) and 0.83 (95% CI=[0.61; 0.93]) for the measurements taken with the goniometer on the same day and for those on two different days. The corresponding values for the modified inclinometer were 0.88 (95% CI=[0.72;0.95]) and 0.81 (95% CI=[0.57; 0.92]). Both instruments were found to have very good test-retest reliability.

Story Theatre in Improving the Students’ Speaking Skills in English

This study was conducted to determine the effectiveness of story theatre in improving speaking skills in English to Grade 12 General Academic Strand (GAS) students, University of Cebu- Main Campus, S.Y. 2020-2021. The result was used as a basis for a proposed action plan. Specifically, the study sought answers to the pretest scores of the control and experimental groups, the posttest scores of the control and experimental groups, the significant difference between their pretest scores, the significant difference between their pretest-posttest scores, and the significant difference between their posttest scores. A quasi-experimental design was used for the control and experimental groups. There were 40 Grade 12 students as subjects of the study. The experimental group was treated with the use of story theatre, while the control group was taught using the lecture method. Pretest and posttest evaluations were used to measure the academic performance of the students for both groups. The findings of the study revealed that most of the students had good level performances. The posttest scores of both groups marked an increase, and the posttest mean value of the experimental group was significantly higher than that of the control group. Student’s speaking skills in the English language are effectively enhanced with the use of story theatre. The interest, retention and learning ability of the students are better realized when they are actively involved with a combination of the written word, acting, movement and characterization.

Hepatic involvement with typhoid fever: a report of nine patients.

Salmonella typhi has been reported to cause hepatic involvement. We studied nine patients with positive blood cultures in order to identify characteristic features of typhoid hepatitis which may help in early diagnosis. Patients who had an illness resembling enteric fever but negative cultures for Salmonella typhi were excluded. No specific clinical features were found consistently and liver function tests were widely variable. Other biochemical abnormalities occurred due to vomiting and renal involvement. Liver biopsy showed focal hepatocellular necrosis and non specific inflammation. Although most responded to conventional antibiotics, it was generally a delayed response. It is recommended that patients with fever greater than 38.5 degrees C and liver abnormalities should undergo blood, urine, stool and/or bone marrow cultures. Liver biopsy may help to differentiate typhoid hepatitis from acute viral hepatitis.

Tranquilizer misuse among active cocaine users: Predictors of initiation

Abstract Introduction and Aims Tranquilizer use is associated with negative health outcomes among people who use drugs. This paper aims to estimate the incidence rate (initiation) and identify predictors of tranquilizer misuse (TM) among cocaine users. Design and Methods A prospective cohort study was conducted in Montreal, Canada. Interviewer‐administered questionnaires were carried out at 3‐month intervals. Initiation was defined as misusing a tranquilizer for the first time during follow‐up. ‘Lasting‐initiation’, defined as reporting TM at the next visit following first use, was also examined. Cox proportional hazard regression analyses were carried out to assess predictors of initiation to TM. Results Among the 245 participants who were eligible for the initiation analyses, 123 started TM during follow‐up for an incidence rate of 40.49 per 100 person‐years (95% confidence interval, CI: 33.80–48.15). Of the 123 initiates, 35.7% were still using at the interview following initiation for an incidence rate of 14.70 per 100 person‐years (95% CI: 10.82–19.56). Multivariate models showed that independent predictors of initiation and ‘lasting initiation’ were identical as having had a criminal activity as the main source of income, having been recently in treatment for a substance use disorder (SUD) and reporting non‐medical use of prescription opioids. Discussion and Conclusions The incidence rate of TM initiation was high among a sample of cocaine users. Initiation was predicted by a problematic drug use pattern involving polydrug use, involvement in the street economy and having been in treatment for a SUD. These findings have implications for prevention and harm reduction strategies.

Effect of magnetic water on strength and workability of high performance concrete

Nowadays, concrete is one of the most important and widely used human product. Improving concrete characteristics have always been one of the fundamental subjects for engineers. Improve the physical properties of water, as one of the main elements of concrete, is one way to improve the characteristics of the concrete. When water passes through the magnetic field, its physical quality has changed, it is called Magnetic water. This study examines the effect of the use of magnetized water (MW) with a solenoid current-carrying, on the compressive strength and workability of high performance concrete. The variables of this study were the intensity of magnetic field, the silica fume replacement level and water to cement ratio in different mixes. The results show that using MW increases the workability of concrete about 36% in average.MW in combination with superplasticizer is more effective than MW on workability and compressive strength of concrete. MW had more positive effects on the samples without silica fume. Increasing the intensity of magnetic field improved the workability, 28 and 90 days compressive strength concrete.

Comparisons of childrens level of recall: Stories told through e-book and picture book

Preschool period covers the years when the child is in a rapid change and development in every aspect. The learning experiences in this period affect children's development. The developments in knowledge technologies affect the child's environment and children's books. This rapid change brings with it some discussions. "Do either traditional methods or digital applications affect children's level of recalling more positively?" This question was the starting point of the research. Thus, the aim of this study is to compare the effect of stories told through e-books and picture books on children's level of recall. The research is based on random design with post-test control group from real experimental designs of quantitative research model. The groups were determined by simple random sampling method and each group consisted of 10 children. The research data were collected by asking the children various questions about the stories and the characters in the stories by the researchers after storytelling through e-book and pictures book. Mann Whitney U test was used to analyze the data. As a result of the study, it was discovered that the children in the group that the story was told by using pictures book have higher level of recall. Key words: Preschool education, story, story book, e-book, recall.

Enabling knowledge brokerage intermediaries to be evidence-informed

Target audience: What Works Centres; other intermediary brokerage agencies; their funders and users; and researchers of research use. Background: Knowledge brokerage and knowledge mobilisation (KM) are generic terms used to describe activities to enable the use of research evidence to inform policy, practice and individual decision making. Knowledge brokerage intermediary (KBI) initiatives facilitate such use of research evidence. This debate paper argues that although the work of KBIs is to enable evidence-informed decision making (EIDM), they may not always be overt and consistent in how they follow the principles of EIDM in their own practice. Key points for discussion: Drawing on examples from existing brokerage initiatives, four areas are suggested where KBIs could be more evidence-informed in their work: (1) needs analysis: evidence-informed in their analysis of where and how the KBI can best contribute to the existing evidence ecosystem; (2) methods and theories of change: evidence-informed in the methods that the KBI uses to achieve its goals; (3) evidence standards: credible standards for making evidence claims; and (4) evaluation and monitoring: evidence-informed evaluation of their own activities and contribution to the knowledge base on evidence use. For each of these areas, questions are suggested for considering the extent that the principles are being followed in practice. Conclusions and implications: KBIs work with evidence but they may not always be evidence-informed in their practice. KBIs could benefit from more overtly attending to the extent that they apply the logic of EIDM to how they work. In doing so, KBIs can advance both the study, and practice, of using research evidence to inform decision making.

Geology and Petrography of Revaites

The contribution deals with theme of revaite, a raw material
for chipped industry in prehistoric times. The authors try to
characterized the rock and determine its source. It has been
known that the revaite pebbles are secondarily deposited in
fluvial gravels. The raw material was found in a gravel pit at
Ostrožska Nova Ves (Matl 2000), on alluvial terraces near
Ostrožska Nova Ves, thence in the sand pit of Hulin and also in
the south-west of Kroměřiž. A rare finding we have from
glacifluvial gravels in Opole-Groszowice in Poland. The authors
also present the qualities of revaites – shape, color,
concentric zoning of partially transported fragments and size
of pebbles. The revaites were used for chipped tools in
prehistoric times. These artifacts are likely in the wider area
of Uherske Hradistě, in the Napajedla Hills and around
Kroměřiž. Revaite artifacts have been described at the
Paleolithic stations Kvasice and Karolin in the Kroměřiž area
in the Přerov area (Vokac et. al. 2001), and at an Aurignacian
station Borsice near Buchlovice (Skrdla et. al. 2003). We have
investigated also thin sections of revaites that yielded relics
of microfossils (algea diatoms). On the basis of the
microfossil findings, the Dynow marlstone and menilite cherts
with layers of silicified shale are supposed to be the source
rocks for revaites. Using the laser ablation (LA–ICP–MS,
carried out by S. Huskova) we have determined chemical
composition of revaites and supposed source rocks to deal with
the question of revaite origin.
