A review of constant time headway policy for automatic vehicle following

This article reviews the relevant issues in constant time headway (CTH) schemes in adaptive cruise control (ACC) systems based on system-level considerations of stability, capacity and safety. From the perspective of stability, CTH schemes can be implemented autonomously while guaranteeing that errors in spacing do not amplify during any maneuver of the lead vehicle in the string. The corresponding control efforts of following vehicles are filtered versions of their immediately preceding vehicles. The primary benefit of ACC systems in terms of relieving congestion is the improvement of throughput; however, this will require a reliable distance regulation at traffic capacity.
Dimensions of learning organization: Implications for human resources effectiveness in commercial banks

This study examines the dimensions of learning organization essential in enhancing Human Resources (HR) effectiveness towards the attainment of the strategic objectives of commercial banks operating in Nigeria. This study adopted a survey research design following a quantitative approach for data collection and analysis procedure. The respondents (professional bankers) were selected using a convenience sampling technique. A structured questionnaire was designed and administered to 305 respondents in the participating commercial banks. The data was analysed using a variance-based structural equation modelling via SmartPLS, version 3.2. 9. The results showcased specific learning dimensions to consider in designing learning and development interventions for HR effectiveness in commercial banks. There is a dearth of literature on the specific learning dimensions that play a prominent role in ensuring HR effectiveness in the banking industry in developing countries, particularly in Nigeria. The outcomes of this study contribute to the extant literature and assist HR business partners in adding value to commercial banks through HR effectiveness.
Reduction of cogging force in slotless linear permanent magnet motors

There are two potential causes of cogging force in linear permanent magnet motors, resulting from the slotting and the finite length of the iron-cored armature. The paper is concerned with slotless motors, for which a technique is described for minimising the cogging force which is produced when the armature has a mild steel sleeve (yoke). By analysing the cogging-force waveform developed at one end of the sleeve and optimising its axial length so that an opposing cogging-force waveform is developed at the other end, it is possible to obtain nearly zero resultant force. The technique has been validated on a prototype motor and found to be effective and simple to implement.
Evaluation of Acute Glial Fibrillary Acidic Protein and Ubiquitin C-Terminal Hydrolase-L1 Plasma Levels in Traumatic Brain Injury Patients with and without Intracranial Lesions

This pilot study aimed to evaluate the association of plasma ubiquitin C-terminal hydrolase-L1 (UCH-L1), glial fibrillary acidic protein (GFAP), and S100 calcium-binding protein B (S100B) with intracranial abnormalities visible on a computed tomography (CT) scan (CT positive) and injury severity in acute traumatic brain injury (TBI). For these purposes, a cohort of 109 adult TBI patients was recruited within 6 h from the injury event. A hyperacute subcohort of 20 patients who had their blood collected within 2 h from injury was analyzed separately for early acute biomarker levels. Levels of GFAP and UCH-L1 were analyzed using the prototype Abbott i-STAT™ TBI Plasma Test (Abbott Laboratories, Abbot Park, IL), alongside S100B measurement (Elecsys; Roche Diagnostics, Penzberg, Germany). In the hyperacute subcohort, GFAP and UCH-L1, but not S100B, levels were significantly higher in the CT-positive group compared to CT-negative patients. AUC values for differentiation between CT-positive and CT-negative patients were 0.97 for GFAP, 0.87 for UCH-L1, and 0.60 for S100B. Severity discrimination, defined by Glasgow Coma Scale (GCS) score, was then analyzed in the total patient cohort. Levels of all three biomarkers were significantly different between mild (GCS, 13–15) and moderate/severe (GCS, 3–12) injury groups. UCH-L1 showed the highest area under the curve value for severity discrimination (0.94), followed by GFAP (0.91) and S100B (0.83). These results support the clinical utility of GFAP and UCH-L1 as TBI biomarkers able to rule out CT-positive injury in acute TBI. Moreover, excellent differentiation of GFAP and UCH-L1 between mild and moderate/severe TBI groups affirms their close association with the underlying pathology.
Integrating research into language teaching and learning: Learners and teachers as co-researchers exploring praxis

Abstract Classroom research has long been recommended as a fruitful avenue for English language teaching (ELT) in applied linguistics. Yet recognition of the value of practitioners exploring their own praxis has only recently come to the fore. In this plenary, I focus on Exploratory Practice, a form of ‘fully inclusive practitioner research’, in which learners as well as teachers are invited to integrate research and pedagogy. Drawing on studies from around the world, I spotlight the potential of learners and teachers to contribute to debates in the fields of language teaching and learning, applied linguistics and social sciences alike. This co-production between learners and teachers illuminates the nexus of research and pedagogy (praxis), providing plentiful puzzles for exploration.
Influence of Temperature on the Substitution of Quartz by Rice Husk Ash (RHA) in Porcelain Composition

Rice Husk Ash (RHA) is a by-product of the agricultural industry which contains high amount of silica. Active silica from RHA has been used progressively to substitute quartz in a porcelain composition and the effect this substitution in relation to temperature on physical and mechanical properties has been investigated. It was found that progressive substitution of RHA in a porcelain composition resulted in early vitrification of the mixture. The compressive strength was highest and the porosity was the least at a temperature of 1200°C on 20wt% substitution of RHA. The improvement in the properties could be attributed to sharp changes in the microstructural features as a result of increase in mullite and glassy phase simultaneously. Hence the extension of study on microstructure and morphology has influence on the physical and mechanical properties.
Evidence for Enzymatic Backbone Methylation of the Main Membrane Lipids in the Archaeon Methanomassiliicoccus luminyensis

Butanetriol and pentanetriol dibiphytanyl glycerol tetraethers are membrane lipids recently discovered in anoxic environments. These lipids differ from typical membrane-spanning tetraether lipids because they possess a nonglycerol backbone. ABSTRACT Butanetriol and pentanetriol dibiphytanyl glycerol tetraethers (BDGTs and PDGTs, respectively) are recently identified classes of archaeal membrane lipids that are prominent constituents in anoxic subseafloor sediments. These lipids are intriguing, as they possess unusual backbones with four or five carbon atoms instead of the canonical three-carbon glycerol backbone. In this study, we examined the biosynthesis of BDGTs and PDGTs by the methanogen Methanomassiliicoccus luminyensis, the only available isolate known to produce these compounds, via stable isotope labeling with [methyl-13C]methionine followed by mass spectrometry analysis. We show that their biosynthesis proceeds from transfer(s) of the terminal methyl group of methionine to the more common archaeal membrane lipids, i.e., glycerol dibiphytanyl glycerol tetraethers (GDGTs). As this methylation targets a methylene group, a radical mechanism involving a radical S-adenosylmethionine (SAM) enzyme is probable. Over the course of the incubation, the abundance of PDGTs relative to BDGTs, expressed as backbone methylation index, increased, implying that backbone methylation may be related to the growth shift to stationary conditions, possibly due to limited energy and/or substrate availability. The increase of the backbone methylation index with increasing sediment age in a sample set from the Mediterranean Sea adds support for such a relationship. IMPORTANCE Butanetriol and pentanetriol dibiphytanyl glycerol tetraethers are membrane lipids recently discovered in anoxic environments. These lipids differ from typical membrane-spanning tetraether lipids because they possess a non-glycerol backbone. The biosynthetic pathway and physiological role of these unique lipids are currently unknown. Here, we show that in the strain Methanomassiliicoccus luminyensis, these lipids are the result of methyl transfer(s) from an S-adenosyl methionine (SAM) intermediate. We observed a relative increase of the doubly methylated compound, pentanetriol dibiphytanyl glycerol tetraether, in the stationary phase of M. luminyensis as well as in the subseafloor of the Mediterranean Sea and thus introduced a backbone methylation index, which could be used to further explore microbial activity in natural settings.
Longhorned Beetles (Coleoptera: Cerambycidae and Disteniidae) Collected in the Canopy of a Dry Tropical Lowland Forest in Panama

Abstract This study characterizes the abundance and richness of longhorned beetles (Coleoptera: Cerambycidae and Disteniidae) collected in the canopy of a dry tropical lowland forest in Panama. The nine tree species sampled included Enterolobium cyclocarpum (Jacq.) Griseb. (Fabaceae), Pseudobombax septenatum (Jacq.) Dugand (Malvaceae), Luehea seemannii Triana & Planch. (Malvaceae), Cordia alliodora (Ruiz. & Pav.) Oken (Boraginaceae), Castilla elastica Sessé ex Cerv. (Moraceae), Anacardium excelsum (Bertero & Balb. ex Kunth) Skeels (Anacardiaceae), Cecropia peltata L. (Urticaceae), Zuelania guidonia (Sw.) Britton & Millsp. (Flacourtiaceae) and Ficus insipida Willd. (Moraceae). A total of 227 specimens of Cerambycidae and Disteniidae were collected. The most abundant species was Trestonia pulcherrima Dillon and Dillon, 1946 (23%), followed by Compsibidion vanum (Thomson, 1867) (16%). The greatest abundance and richness of beetles were recorded in the canopy of L. seemannii (90 individuals = 39%). The presence of these beetles in the forest canopy is associated with their general preference for large trees, highly complex foliar canopy architecture, and the availability of resources for the development and feeding of larvae and adults. Synchronization with plant phenology may explain the greater abundance and richness observed in L. seemannii.
Multi-tier service restoration through network reconfiguration and capacitor control for large-scale radial distribution networks

A fast and effective service restoration algorithm allowing multi-tier or system-wide switching and capacitor control actions is developed for large-scale, radial distribution networks. The service restoration problem is formulated as a constrained multiple-objective optimization problem. A solution algorithm designed to consider networks with predominately manual switches is developed which utilizes information calculated from three-phase power flow analysis to restore as much priority and total load as possible while requiring a minimal number of control actions and amount of geographic travel distance. Simulation results are presented for a 399 bus distribution network and compared to a service restoration algorithm which avoids multi-tier switching.

Nucleotide excision repair is carried out by DNA helicase encoded by xeroderma pigmentosum group D (XPD) genes and aberrations in the XPD gene predisposes to increased risk of cancer. The present study aimed to investigate GSTT1, GSTM1 and XPD polymorphisms in newly diagnosed chronic myeloid leukemia (CML) patients and to examine the association of these polymorphisms with the risk of developing CML. Patients and Methods: This case–control study was carried out from June 2019 to August 2021 involving 150 newly diagnosed patients with CML and an equal number of randomly selected ageand sex-matched healthy individuals. A multiplex-PCR assay was used to genotype GSTT1 null and GSTM1 null polymorphisms. XPD gene polymorphism was detected by PCR-RFLP using predesigned gene-specific primers. Results: GSTT1 and GSTM1 null polymorphisms were detected in 42.7% and 61.3% of cases, respectively, compared to 18% and 35.3% for controls. The combination of both GST null polymorphisms revealed a significant association with CML. Frequencies of XPD Lys751Gln genotypes in cases were 62.7% heterozygous Lys/Gln, 24% homozygous Lys/ Lys and 13.3% homozygous Gln/Gln, while in the controls were 74.7%, 20%, and 5.3%, respectively. Significant differences were also noted regarding the combination of GSTT1/ GSTM1 null with XPD Lys/Lys, and GSTM1 null with XPD Lys/Lys. Conclusion: In conclusion, GSTT1 null, GSTM1 null and XPD polymorphisms showed positive association with the risk of development of CML. Furthermore, age and gender did not exhibit any association with the studied polymorphisms, while CML phases were associated with GSTT1 null polymorphism.
Pressure transient control: Part I — criteria for transient analysis and control

Pressure transient propagation is a wholly natural consequence of any change in operating conditions for a fluid carrying system. Rapid changes in flow conditions generate surge conditions that may result in system failure. The analysis of these phenomena has progressed over the past 100 years from empirical research aimed at the protection of large-scale pipeline and plant networks to the development of computing simulations to support system design. Pressure surge analysis is therefore a consideration in the design and operation of all fluid systems: the objective of such an analysis being the prediction, control and suppression of transients. This paper presents the background to the development of surge alleviation, from traditional pipeline protection to applications within building drainage and vent systems, thereby stressing that the system failure consequences of transient propagation are dependent on the particular system, independent of absolute surge pressure, and that system protection criteria may be developed that apply regardless of the system or the severity of the transient. Practical application: The control of air pressure transients in building drainage systems has been limited due to the need to attenuate positive pressure propagation via an open termination at roof level - a poor solution as the transient will have affected all system trap seals before reaching the relief vent. The Positive Air Pressure Attenuator - an expandable bag that controls the rate of change of entrained airflow within the system - reduces the possibility of trapseal loss due to positive transient propagation. Potentially this is a major contribution to vent system design that could revolutionize 150 years of design methodology.

Evidence-Based Policy Learning

The past years have seen the development and deployment of machine-learning algorithms to estimate personalized treatment-assignment policies from randomized controlled trials. Yet such algorithms typically optimize expected outcomes without taking into account that treatment assignments are frequently subject to hypothesis testing. In this article, we explicitly take signiﬁcance testing of the effect of treatment-assignment policies into account, and consider assignments that optimize the probability of ﬁnding a subset of individuals with a statistically signiﬁcant positive treatment effect. We provide an efﬁcient implementation using decision trees, and demonstrate its gain over selecting subsets based on positive (estimated) treatment effects. Compared to standard tree-based regression and classiﬁcation tools, this approach tends to yield substantially higher power in detecting subgroups affected by the treatment.
Low-frequency Flux Density Measurements and Pulsars with GHz-peaked Spectra

We have estimated flux densities of several pulsars from radio interferometric observations mainly at 325 MHz using the Giant Metrewave Radio Telescope. The new observations allowed us to update the spectral nature of the observed pulsars, and in six sources we identified relatively high frequency turnovers, which can be classified as new GHz-peaked spectrum (GPS) pulsars. For such objects the turnover in the spectrum is most likely caused by absorption in the immediate vicinity of the pulsar (or in the interstellar medium). We modeled the turnover spectra using the thermal free–free absorption model and the physical parameters obtained from the fits enabled us to identify the environments that could potentially be responsible for the observed absorption, such as pulsar wind nebulae, supernova remnant nebulae or H ii regions. The discovery of 6 new GPS pulsars brings the total number of such objects to 33 and we discuss the properties of the entire sample.
ON THE STRUCTURE OF EQUIVARIANT FORMAL GROUP LAWS

We give a new proof of Greenlees’s conjecture stating that for an abelian compact Lie group G, the stable G-equivariant complex cobordism ring MU ∗ is the G-equivariant Lazard ring, i.e. the ring representing universal G-equivariant formal group laws. In the process, we give a presentation of MU ∗ as a deformation of the non-equivariant Lazard ring L =MU∗.
Characterization of the palladium plasma produced by nanosecond pulsed 532 nm and 1064 nm wavelength lasers

Palladium plasma produced by nanosecond pulsed 532 nm and 1064 nm wavelengths lasers is studied with the help of planer Langmuir probe. The experiment is conducted over a wide range of the laser fluence (1.6–40 J cm−2). The measured time of flight ions distributions are used to infer total charge, kinetic energy of the palladium ions and plasma parameters. Our results indicate that the ion charge produced by both laser wavelengths is an increasing function of the laser fluence. Initially, the ion charge produced by 1064 nm is lower than 532 nm, but it increases at much faster rate with the rise of laser fluence as the inverse bremsstrahlung plasma heating prevails at higher plasma densities. The most probable kinetic energy of the Pd ions produced by 1064 nm wavelength is also lower than that of 532 nm. The time varying plasma electron temperature and electron density are derived from the current–voltage plots of the two plasmas. For both wavelengths, the electron temperature and electron density rapidly climb to a maximum value and then gradually decline with time. However, in case of the 532 nm, the electron temperature and electron density remain consistently high throughout the laser plasma. The results are compared the available literature and discussed by considering surface reflectivity, ablation rate of the Pd target and laser plasma heating. The results presented in this work will provide more insight into the process of laser ablation and can be useful for the development of laser-plasma ion sources.
Appendix for “R-Drop: Regularized Dropout for Neural Networks”

For all the NMT tasks, we use the public datasets from IWSLT competitions1 and WMT competitions2. We tokenize all the datasets with byte-pair-encoding (BPE) [11] approach with the dictionary built jointly upon the source and target sentence pairs except the IWSLT17 En↔Zh translation dataset that is built separately. After tokenization, the resulted vocabularies for IWSLT datasets are near 10k, while for WMT datasets, the vocabulary size is about 32k.
