THE TRIPLE EVOLUTION DYNAMICAL INSTABILITY: STELLAR COLLISIONS IN THE FIELD AND THE FORMATION OF EXOTIC BINARIES

Physical collisions and close approaches between stars play an important role in the formation of exotic stellar systems. Standard theories suggest that collisions are rare, occurring only via random encounters between stars in dense clusters. We present a different formation pathway, the triple evolution dynamical instability (TEDI), in which mass loss in an evolving triple star system causes orbital instability. The subsequent chaotic orbital evolution of the stars triggers close encounters, collisions, exchanges between the stellar components, and the dynamical formation of eccentric compact binaries (including Sirius-like binaries). We demonstrate that the rate of stellar collisions due to the TEDI is approximately 10−4 yr−1 per Milky Way Galaxy, which is nearly 30 times higher than the total collision rate due to random encounters in the Galactic globular clusters. Moreover, we find that the dominant type of stellar collision is qualitatively different; most collisions involve asymptotic giant branch stars, rather than main sequence or slightly evolved stars, which dominate collisions in globular clusters. The TEDI mechanism should lead us to revise our understanding of collisions and the formation of compact, eccentric binaries in the field.
An Efficient Algorithm for Maximum Trajectory Coverage Query With Approximation Guarantee

In this paper, we study the $k$ Maximum Trajectory Coverage Query, which aims to find $k$ routes in a public transport system that can serve the maximum number of users with given journey trajectories. In existing studies, they only consider independent service that includes no transfers, but overlooks the aggregative service that includes transfer of multiple routes, resulting in inferior results. In our study, we consider both independent and aggregative services, which can help provide more meaningful results. However, the problem is NP-hard and non-submodular. To address this problem, we propose a greedy algorithm that iteratively selects the route with the maximum marginal gain considering both independent and aggregative services, and show that it outperforms the competitor by up to 60% in terms of accuracy. Since the problem is non-submodular, the greedy algorithm typically does not provide any approximation guarantee. By a mild assumption, we show that our proposed solution provides a constant approximation with respect to the optimal one. Moreover, since we need to consider both the independent and aggregative service, our greedy algorithm becomes more complicated and brings additional time overheads. To overcome such a deficiency, we further accelerate our solution using several heuristics and present an efficient method for spatially associating trajectories and routes. Extensive experiments on real-world datasets demonstrate that our optimisation brings up to an order of magnitude speedup and even outperforms existing solutions (that consider no aggregative service) by 2–3 times.
Deterministic Dithering-Based 12-b 8-MS/s SAR ADC in 0.18-μm CMOS

This letter presents a 12-bit binary-weighted successive approximation register (SAR) ADC calibrated using self-subtractive deterministic dithering to determine the capacitor mismatch. A prototype 12-bit SAR ADC sampling at 8 MHz is realized in UMC 180-nm CMOS process and achieves an ENOB of 11.7-bits while consuming <inline-formula> <tex-math notation="LaTeX">${600~\mu }\text{W}$ </tex-math></inline-formula> of power from 1.8-V supply, thereby achieving a figure-of-merit of 22.5 fJ/conv-s and occupying only 0.13 mm2.
THE NUMBER DENSITY OF QUIESCENT COMPACT GALAXIES AT INTERMEDIATE REDSHIFT

Massive compact systems at 0.2 < z < 0.6 are the missing link between the predominantly compact population of massive quiescent galaxies at high redshift and their analogs and relics in the local volume. The evolution in number density of these extreme objects over cosmic time is the crucial constraining factor for the models of massive galaxy assembly. We select a large sample of ∼200 intermediate-redshift massive compacts from the Baryon Oscillation Spectroscopic Survey (BOSS) spectroscopy by identifying point-like Sloan Digital Sky Survey photometric sources with spectroscopic signatures of evolved redshifted galaxies. A subset of our targets have publicly available high-resolution ground-based images that we use to augment the dynamical and stellar population properties of these systems by their structural parameters. We confirm that all BOSS compact candidates are as compact as their high-redshift massive counterparts and less than half the size of similarly massive systems at z ∼ 0. We use the completeness-corrected numbers of BOSS compacts to compute lower limits on their number densities in narrow redshift bins spanning the range of our sample. The abundance of extremely dense quiescent galaxies at 0.2 < z < 0.6 is in excellent agreement with the number densities of these systems at high redshift. Our lower limits support the models of massive galaxy assembly through a series of minor mergers over the redshift range 0 < z < 2.
Search for supersymmetry in pp collisions with all-hadronic final states using the αT variable with the CMS detector at the LHC

A search for supersymmetry in the exclusive hadronic and missing energy channel is presented on 5 fb 1 of data collected using the CMS detector at the LHC. The data were produced at a center-of-mass energy of 7 TeV. The kinematic discriminator ↵T is used to select signal events which are then binned in terms of the visible energy per event. The e ciency of the hadronic Level-1 triggers is measured though-out the data taking period and a scheme to reduce the e↵ects of multiple collisions per bunch crossing on the cross section of the trigger paths is studied, implemented and tested in situ. These e ciency measurements are considered in the development of an analysis specific trigger, the performance of which is measured in situ, with the final e ciencies taken into account in the presented analysis. A data driven background estimation method is used to predict the expected yield in the signal regions from Standard Model processes. In the absence of an observed excess, limits are set to the 95% confidence level on the production cross section and masses of new particles. In the context of the Constrained Minimal Supersymmetric Model (CMSSM), squarks and gluinos with a mass of up to 1 TeV are excluded. In terms of simplified models with various light and heavy flavour final states, squarks and gluinos are excluded at a mass of ⇡ 1 TeV for a Lightest Supersymmetric Particle (LSP) mass of up to ⇡ 500 GeV. Natural units (h̄ = c = 1) are used though-out.
Nutritional evaluation of chia (Salvia hispanica) seeds and oil in broiler diets

- Two experiments were carried with broilers from 29 to 42 days of age for the nutritional evaluation of dietary chia. Thus, the nitrogen-corrected apparent metabolizable energy (AMEn) and the apparent metabolizability coefficients of gross energy and ether extract of chia seeds and oil, toasted soybean grain (TSG), and soybean oil were determined in the experiment I, by total excreta collection method, using 120 broilers. Each experimental diet (reference diet [RD] and four diets with the tested feedstuffs) was evaluated in eight replicates of three broilers. The TSG and chia seeds replaced the RD in 250 g/kg, whereas soybean and chia oils replaced the RD in 100 g/kg. Simultaneously, a second experiment was carried subdivided into two trials. In the performance trial, we evaluated the dietary feedstuffs effects on performance, carcass and cut yields, blood parameters, and activity of lipogenic enzymes. The nutrient metabolizability coefficients and AMEn were evaluated in the metabolism trial. The AMEn values of 37.49, 37.35, 15.85, and 8.43 MJ/kg of dry matter were determined for chia oil, soybean oil, TSG, and chia seeds, respectively (experiment I). In the second experiment, the best feed conversion was observed in broilers fed diets containing chia oil and TSG. However, the diet formulated with chia seeds worsened broiler feed conversion, exhibited the smaller energy value and apparent metabolizability coefficient of the ether extract, and increased the activity of the malic enzyme and serum total cholesterol level. There was no difference for glucose-6-phosphate dehydrogenase activity and high-density lipoprotein cholesterol level. In general, chia oil showed to be efficient in replacing soybean oil in broiler diets.
Critical political consciousness within nepantla as transformative: The experiences and pedagogy of a Palestinian world history teacher

Abstract This case study of a Palestinian American social studies teacher in a predominantly affluent public school in New York City utilizes the Chicana/Latina feminist theoretical concept of nepantla and the literature on teachers of Color in social studies education. This article addresses how her critical political consciousness, identities, and experiences as a teacher of Color influenced the ways she navigated through the Orientalist and Eurocentric social studies curriculum in the United States. Findings show three tensions in her life contributed to the development of her political consciousness and further influenced her teaching through pedagogies of nepantla. This study provides a perspective on how teachers with politicized identities navigate through systems of oppression, including geopolitical realities and school curriculum and infrastructure, by teaching world history from critical perspectives and centering people and civilizations of Color.
Probing Gluon Helicity with Dijets from $\sqrt s$ = 510 GeV Polarized Proton Collisions at STAR

The production of jets in polarized proton collisions at STAR is dominated by quark-gluon and gluon-gluon scattering processes. The dijet longitudinal double-spin asymmetry $(A_{LL})$ is sensitive to the helicity distributions and may be used to extract information about the gluon helicity contribution $\Delta{g(x,Q^2)}$ to the spin of the proton. Previous STAR jet measurements at $\sqrt s$ = 200 GeV show evidence of polarized gluons for gluon momentum fractions above 0.05. The measurement of dijet $A_{LL}$ at $\sqrt s$ = 510 GeV will extend the current constraints on $\Delta{g(x,Q^2)}$ to lower gluon momentum fractions and allow for the reconstruction of the partonic kinematics at leading order. These proceedings present preliminary results from the dijet $A_{LL}$ measurement from $\sim50 pb^{-1}$ of $\sim50 \%$ polarized proton data taken during the 2012 RHIC run.
Empirical Analysis of Data Streaming and Batch Learning Models for Network Intrusion Detection

Network intrusion, such as denial of service, probing attacks, and phishing, comprises some of the complex threats that have put the online community at risk. The increase in the number of these attacks has given rise to a serious interest in the research community to curb the menace. One of the research efforts is to have an intrusion detection mechanism in place. Batch learning and data streaming are approaches used for processing the huge amount of data required for proper intrusion detection. Batch learning, despite its advantages, has been faulted for poor scalability due to the constant re-training of new training instances. Hence, this paper seeks to conduct a comparative study using selected batch learning and data streaming algorithms. The batch learning and data streaming algorithms considered are J48, projective adaptive resonance theory (PART), Hoeffding tree (HT) and OzaBagAdwin (OBA). Furthermore, binary and multiclass classification problems are considered for the tested algorithms. Experimental results show that data streaming algorithms achieved considerably higher performance in binary classification problems when compared with batch learning algorithms. Specifically, binary classification produced J48 (94.73), PART (92.83), HT (98.38), and OBA (99.67), and multiclass classification produced J48 (87.66), PART (87.05), HT (71.98), OBA (82.80) based on accuracy. Hence, the use of data streaming algorithms to solve the scalability issue and allow real-time detection of network intrusion is highly recommended.
One Year Survival of Wild-Type Adenocarcinoma Lung Cancer Patients Receiving Chemotherapy at dr. Saiful Anwar Hospital, Malang

Background: Lung cancer is one of the most common malignancies that leads to mortality. In Indonesia, lung cancer ranks first in men and third in women. The most common histological type of lung cancer is adenocarcinoma. Adenocarcinoma lung cancer is divided into 2 types, namely EGFR mutations and no mutations (wild-type). Chemotherapy is the treatment of choice for advanced wild-type adenocarcinoma lung cancer. This study aimed to assess the one-year survival of wild-type adenocarcinoma lung cancer patients receiving chemotherapy. Method: This study used a cross-sectional study design.Data were taken from the medical records of cancer patients at Dr. Saiful Anwar Hospital Malang in 2018-2019. Data were processed and analyzed by chi-square test. Results: Of the 54 subjects, 24 patients received carboplatin/ pemetrexed (44.4%), 15 patients received carboplatin/paclitaxel (27.8%), 9 patients received carboplatin/gemcitabine (16.7%), 2 patients received pemetrexed (3.7%), and 4 patients received gemcitabine (7.4%). The chemotherapy drug regimen had no correlation with one-year survival (P=0.899). Conclusion: There wasno significant difference between one-year survival andchemotherapy drug regimens. This study required a larger sample to minimize bias.
Isotopic Niche Analysis of Long-Finned Pilot Whales (Globicephala melas edwardii) in Aotearoa New Zealand Waters

Simple Summary Isotopic niche analyses can elucidate a species’ foraging ecology. Using isotopic values of δ13C, δ15N and δ34S, the isotopic niche of long-finned pilot whales (Globicephala melas edwardii) in Aotearoa New Zealand was investigated for animals that stranded in six different events across two locations between 2009 and 2017. Generalised additive models revealed that stranding event was a stronger predictor for δ13C and δ15N values than body length, sex, or reproductive status, indicating that spatiotemporal differences explained isotopic variation of G. m. edwardii in New Zealand waters better than ontogenetic factors. Abstract The quantification of a species’ trophic niche is important to understand the species ecology and its interactions with the ecosystem it resides in. Despite the high frequency of long-finned pilot whale (Globicephala melas edwardii) strandings on the Aotearoa New Zealand coast, their trophic niche remains poorly understood. To assess the isotopic niche of G. m. edwardii within New Zealand, ontogenetic (sex, total body length, age, maturity status, reproductive group) and spatiotemporal (stranding location, stranding event, and stranding year) variation were investigated. Stable isotopes of carbon (δ13C) and nitrogen (δ15N) were examined from skin samples of 125 G. m. edwardii (67 females and 58 males) collected at mass-stranding events at Onetahua Farewell Spit in 2009 (n = 20), 2011 (n = 20), 2014 (n = 27) and 2017 (n = 20) and at Rakiura Stewart Island in 2010 (n = 19) and 2011 (n = 19). Variations in δ34S values were examined for a subset of 36 individuals. General additive models revealed that stranding event was the strongest predictor for δ13C and δ15N values, whilst sex was the strongest predictor of δ34S isotopic values. Although similar within years, δ13C values were lower in 2014 and 2017 compared to all other years. Furthermore, δ15N values were higher within Farewell Spit 2017 compared to any other stranding event. This suggests that the individuals stranded in Farewell Spit in 2017 may have been feeding at a higher trophic level, or that the nitrogen baseline may have been higher in 2017 than in other years. Spatiotemporal differences explained isotopic variation of G. m. edwardii in New Zealand waters better than ontogenetic factors.
Scoring rules and the inevitability of probability

Abstract : Let a person express his uncertainty about an event E, conditional upon an event F, by a number x and let him be given, as a result, a score which depends on x and the truth or falsity of E when F is true. It is shown that if the scores are additive for different events and if the person chooses admissible values only, then there exists a known transform of the values x to values which are probabilities. In particular, it follows that values x derived by significance tests, confidence intervals or by the rules of fuzzy logic are inadmissible. Only probability is a sensible description of uncertainty.
Methane Extraction and Resource Utilization Based on Multisource Data Fusion

Gas clusters can reprove the sewage ability of flame-permeability char joint, but the interaction motion between proposed vapor molecules and gasoline-confine charcoal during the wind enema advance is still unclear. For this consideration, supported by the surface assimilation figure of qualifier-enclose char, the magnificent orthodox whole Monte Carlo (GCMC) manner was interesting to ponder the elution conduct of CH4 in the wind-confine charcoal configuration after the farding bag of N2/CO2 under distinct enema stamp. The clockwork of N2/C advances the elution of CH4 in charcoal. The examination ensues showed the following: (1) Compared with the enema of N2, the gasoline-restrain charcoal has more familiar CH4 molecules after CO2 enema, and the constituting force of the CH4-CO2 system is everywhere more humble than that of the CH4-N2 system, the former is more fix. (2) In the same enema pattern, obtained with the CH4-N2 system, the CH4 grout indicated more regular distribution in the CH4-CO2 system. CH4 heptane is more active, the expansion cooperation of CH4 in the CH4-CO2 system is more, and the effect of CO2 in promoting the elution of CH4 is better. (3) After CO2/N2 is interjected into the fart-hold charcoal construction, as the enema compression extension, the referring concentrations of CO2, N2, and CH4 in the coping wax, the opposite to major of CH4 in the CH4-CO2 system is the zenith everywhere. In the CH4—N2 system, the opposite to major of CO2 in the CH4 and CH4—CO2 system is in the centric, and the opposite to major of N2 in the CH4—N2 system is the lowermost. (4) The reasonably enema affliction for N2 to raise CH4 elution is between 2 and 4 MPa, and CO2 is honest to advance CH4 elution. The enema urgency is between 3 and 4 MPa. Based on this data, methane extraction and resource utilization can be improved to a certain extent. The result has shown that the inquiry effect can condition speculative uphold for the research studies of char cicatrix petrol enema irritation technology.
Green synthesised CuNPs using Alhagi maurorum extract and its ability to amelioration of Mycoplasma pneumoniae infected pneumonia mice model

Abstract In this study, copper nanoparticles were synthesised according to green chemistry rules using the aqueous extract of Alhagi maurorum. The green-synthesised CuNPs were characterised using different techniques such as EDX, FE-SEM, XRD and FT-IR. The FE-SEM results confirm spherical morphology for the nanoparticles with a size of 42.68–68.87 nm. In vivo, the Mycoplasma pneumonia injection was applied for inducing pneumonia in the BALB/c mice, also the treatment was with CuNPs. The serum parameters such as inflammatory mediators (IL-6, TNF-α, IL-8, TGF and IL-1), total cell counts, and total protein content levels were evaluated. CuNPs regulated the levels of the inflammatory mediators in the infected mice. The cellular arrangements at the histopathological images were ameliorated with the administration of CuNPs. At the antioxidant test, the CuNPs and BHT removed 50% of free radicals at the concentrations of 181 and 110 µg/ml. In conclusion, the results revealed the ameliorative property of CuNPs green-formulated by A. maurorum aqueous extract on M. pneumoniae infected pneumonia mice model.
Determinants Of Muslim Intention In Yogyakarta To Pay ZIS Online During The Covid-19 Pandemic

The Covid-19 pandemic has become a period of crisis that has brought many changes to people's lifestyles. The Covid-19 pandemic makes people afraid of being infected by physical contact in every activity. Lack of research on this topic, so this study aims to find out how the determinants of people in Yogyakarta to pay zakat infaq and or alms online during the Covid-19 pandemic were modified based on previous research. This study examines data from 119 respondents with a sample of people living or domiciled in DI Yogyakarta, having income and being Muslim, and having paid zakat infaq and or alms online which was taken by random sampling which was then tested using SEM-PLS analysis with analytical tools. WarpPLS 7. The results of the analysis show that the perceived risk (PR) variable can affect all variables in the UTAUT 2 model to pay zakat, infaq, and sedekah or alms (ZIS) online, but cannot influence interest or behavioural intention. Then in the analysis to determine interest, the variables of performance expectancy, effort expectancy, social influence, and price value cannot influence people's interest in paying zakat infaq and alms online, while facilitating conditions, hedonic motivation and habit can influence it.
The Diagnostic Value of Bedside Echocardiography and Lower Extremity Blood Vessels in Acute Pulmonary Embolism

Objective The study aimed to evaluate the value of bedside echocardiography (TTE) and lower extremity blood vessels in diagnosis and prognosis of acute pulmonary embolism (APE). Methods A retrospective study was performed on 53 patients with APE diagnosed by CT pulmonary angiography (CTPA) (systemic systolic blood pressure was >90 mmHg at time of consultation, and systemic systolic blood pressure decreased by <40 mmHg compared with basic value in those with hypertension). All patients underwent TTE examination before treatment. The high-risk factors, clinical manifestations, laboratory tests, and prognosis were retrospectively analyzed. Results The rate of PE-related deterioration (cardiopulmonary resuscitation, tracheal intubation, cardiogenic shock, and death) within 14 days of hospitalization in RVD was 28%, and mortality rate (sudden death) was 20%, compared with non-RVD (both 0%). TTE examination showed that RVD as a predictor of pulmonary embolism-related death had a sensitivity of 100%, a specificity of 58%, a positive predictive value of 20%, and a negative predictive value of 100%. Conclusions (1) TTE has increasingly shown obvious advantages in diagnosis of APE. It can detect direct or indirect signs of pulmonary embolism, confirm diagnosis or suspected diagnosis, and noninvasively and dynamically observe hemodynamic changes of heart in patients with acute PTE before and after treatment. (2) The PE-related exacerbation rate (28%) or mortality (20%) of APE patients in normotensive with RVD was higher without RVD (0%). RVD is an independent predictor of poor prognosis in normotensive acute PTE. TTE tests allow people to identify people at risk of early death. The short-term prognosis of patients without RVD was better (14 days).
