The Validity of Hawkin Dynamics Wireless Dual Force Plates for Measuring Countermovement Jump and Drop Jump Variables

Force plate testing is becoming more commonplace in sport due to the advent of commercially available, portable, and affordable force plate systems (i.e., hardware and software). Following the validation of the Hawkin Dynamics Inc. (HD) proprietary software in recent literature, the aim of this study was to determine the concurrent validity of the HD wireless dual force plate hardware for assessing vertical jumps. During a single testing session, the HD force plates were placed directly atop two adjacent Advanced Mechanical Technology Inc. in-ground force plates (the “gold standard”) to simultaneously collect vertical ground reaction forces produced by 20 participants (27 ± 6 years, 85 ± 14 kg, 176.5 ± 9.23 cm) during the countermovement jump (CMJ) and drop jump (DJ) tests (1000 Hz). Agreement between force plate systems was determined via ordinary least products regression using bootstrapped 95% confidence intervals. No bias was present between the two force plate systems for any of the CMJ and DJ variables, except DJ peak braking force (proportional bias) and DJ peak braking power (fixed and proportional bias). The HD system may be considered a valid alternative to the industry gold standard for assessing vertical jumps because fixed or proportional bias was identified for none of the CMJ variables (n = 17) and only 2 out of 18 DJ variables.
A new evolutionary algorithm for solving constrained optimization problems

After analyzing the drawbacks of existing constrained optimization evolutionary algorithms(COEAs),a new algorithm,which effectively combines multi-objective optimization with global and local search,was proposed to handle constrained optimization problems(COPs). In the process of the global search,as a niching genetic algorithm(NGA),crowding operator accepts the winner of the similar parent and offspring as a member of the next population based on Pareto dominance.During the local search,firstly,Pareto strength value is computed for each individual,which depends on the number of individuals in the subpopulation dominated by the current individual,and subsequently the selection of individual is based on the Pareto strength value.The experimental results show that the algorithm proposed is very suitable for functions with high dimension and multimodality.In addition,it is clear that the new algorithm is steadier than other COEAs from the literature in dealing with COPs.

Application of atomic decomposition based on PSO in inter-harmonics analysis

Interharmonic is a kind of harmonic signal which is not an integer of the fundamental frequency component. It is harmful to power quality and reduces power system reliability, so measuring inter-harmonics accurately is important to power system safety and stability. This paper introduces the atomic decomposition based on particle swarm optimization to the measurement and analysis of inter-harmonics in power system for the first time, which can overcome the shortcoming such as long computing time of traditional matching pursuit algorithm. This method applies the particle swarm optimization to the atom decomposition iterative optimization process, selects the best matched atoms reflecting the signal feature by comparing the particles' best fitness values, extracts harmonics and inter-harmonics component, obtains the time-frequency distribution which has high time-frequency resolution and is independent of the cross-term interference, and finally analyzes the power system harmonic accurately. The two simulation examples indicate the method has high accuracy, better adaptivity and anti-noise abilities. It also provides a new way for the accurate analysis of power system inter-harmonics.

The Diagnostic English Language Tracking Assessment (DELTA) writing project: a case for post-entry assessment policies and practices in Hong Kong universities

This article describes undergraduate English language support in the context of universities in Hong Kong, with reference to early academic writing needs and support. It focuses specifically on the writing needs of post-entry year 1 students as reported in a series of Hong Kong based studies, and on the recent outcomes of a project funded by an Education Research Grant (ERG): The Diagnostic English Language Tracking Assessment (DELTA) – The Writing Assessment. These studies have revealed that many undergraduate students, whilst obtaining university mandated minimum entry levels for English, are challenged by the demands of academic writing when studying in Hong Kong EMI (English medium instruction) universities. This article reports on this situation and positions DELTA as a desirable post-entry assessment instrument, arguing that it is a critical part of a multilayered approach to addressing the poor English language levels of novice Hong Kong undergraduate students.
Fluorescence-Based Accurate Estimation of Chlorophyll in Tea Leaves Using Smartphone

Estimation of plant leaf chlorophyll is critical for the assessment of overall health condition of plants. The existing detection methods demand relatively expensive and bulky instruments, thus restricting their use for onsite investigations. The present work demonstrates a low-cost, compact fluorescence-based sensor using a smartphone to estimate the chlorophyll content in plant leaves. The extracted plant chlorophyll samples have been optically excited by using an external LED with a peak emission wavelength of 475 nm, and the corresponding emitted fluorescence signals at 679 nm have been recorded by the ambient light sensor of the phone. A 3-D printed compact setup has been designed to couple it with the phone to record the emitted fluorescence signal intensity from the sample. Chlorophyll concentrations in the range of 1–12 mg/g prepared from fresh tea leaves have been accurately estimated with a sensitivity of 0.068 AU g/mg and a limit of detection (LoD) of $0.618 \mu \text{g}$ /L. The performance of the proposed smartphone sensor has been assessed by comparing the data with the commercial chlorophyll meter.
Optical characterisation and analysis of multi-mode pixels for use in future far infrared telescopes

In this paper we present the development and verification of feed horn simulation code based on the mode- matching technique to simulate the electromagnetic performance of waveguide based structures of rectangular cross-section. This code is required to model multi-mode pyramidal horns which may be required for future far infrared (far IR) space missions where wavelengths in the range of 30 to 200 µm will be analysed. Multi-mode pyramidal horns can be used effectively to couple radiation to sensitive superconducting devices like Kinetic Inductance Detectors (KIDs) or Transition Edge Sensor (TES) detectors. These detectors could be placed in integrating cavities (to further increase the efficiency) with an absorbing layer used to couple to the radiation. The developed code is capable of modelling each of these elements, and so will allow full optical characterisation of such pixels and allow an optical efficiency to be calculated effectively. As the signals being measured at these short wavelengths are at an extremely low level, the throughput of the system must be maximised and so multi-mode systems are proposed. To this end, the focal planes of future far IR missions may consist of an array of multi-mode rectangular feed horns feeding an array of, for example, TES devices contained in individual integrating cavities. Such TES arrays have been fabricated by SRON Groningen and are currently undergoing comprehensive optical, electrical and thermal verification. In order to fully understand and validate the optical performance of the receiver system, it is necessary to develop comprehensive and robust optical models in parallel. We outline the development and verification of this optical modelling software by means of applying it to a representative multi-mode system operating at 150 GHz in order to obtain sufficiently short execution times so as to comprehensively test the code. SAFARI (SPICA FAR infrared Instrument) is a far infrared imaging grating spectrometer, to be proposed as an ESA M5 mission. It is planned for this mission to be launched on board the proposed SPICA (SPace Infrared telescope for Cosmology and Astrophysics) mission, in collaboration with JAXA. SAFARI is planned to operate in the 1.5-10 THz band, focussing on the formation and evolution of galaxies, stars and planetary systems. The pixel that drove the development of the techniques presented in this paper is typical of one option that could be implemented in the SAFARI focal plane, and so the ability to accurately understand and characterise such pixels is critical in the design phase of the next generation of far IR telescopes.
Effects of Plant-Based Diets on Anthropometric and Cardiometabolic Markers in Adults: An Umbrella Review

We conducted an umbrella review to consolidate the evidence of adopting plant-based diets on anthropometric and cardiometabolic outcomes. Six electronic databases (CINAHL, EMBASE, PubMed, Scopus, the Cochrane Library, and Web of Science) were searched for systematic reviews with meta-analysis (SRMAs) published from each journal’s inception until 1 October 2022. Effect sizes from SRMAs and primary studies were pooled separately using random effects models. Overlapping primary studies were removed for primary studies’ analyses. Seven SRMAs representing 51 primary studies were included, suggesting significant benefits of plant-based diets on weight (−2.09 kg, 95% CI: −3.56, −0.62 kg, p = 0.01, I2 = 95.6%), body mass index (−0.95 kg/m2, 95% CI: −1.26, −0.63 kg/m2, p = 0.002; I2 = 45.1%), waist circumference (−2.20 cm, 95% CI: −0.08, 0.00 cm, p = 0.04; I2 = 88.4%), fasting blood glucose (−0.11 mmol/L, 95% CI: −0.13, −0.09 mmol/L, p < 0.001, I2 = 18.2%), and low-density lipoprotein cholesterol (−0.31 mmol/L, 95% CI: −0.41, −0.20 mmol/L, p < 0.001, I2 = 65.6%). Changes in high-density lipoprotein cholesterol, triglycerides, and blood pressure were not statistically significant. Generally, plant-based diets were recommended to improve anthropometry, lipid profile, and glucose metabolism. However, findings should be interpreted with caution, because most of the reviews were rated to be of low credibility of evidence and were largely based on Western eating habits and traditions, which may limit the generalizability of findings.
Ergodic theorems with respect to lebesgue

We study, from the ergodic viewpoint, the asymptotic dynamics in the future of a full Lebesgue set of initial states. The dynamical systems under research are deterministic and evolving with discrete time n ∈ N by the forward iterations of any continuous map f: M → M acting on a finite-dimensional, compact and Riemannian manifold M. First, we revisit the classic definition of physical or SRB probability measures, and its generalized notion of weak physical probabilities. Then, inspired in the statistical meaning of the ergodic attractors defined by Pugh and Schub, which support ergodic physical measures, we define the more general concept of ergodic-like attractor. We prove that any such generalized attractor is the support of weak physical probabilities and conversely. Then, we revisit the proof of existence of weak physical probabilities and conclude that any continuous dynamics exhibits at least one ergodic-like attractor.

Remembering the Past for Better Future: Positive Effect of Nostalgia on Hope

Living in uncertainty situation is not easy for some human being. It gives effect for mental health and decreasing hope for sustainability harmonize living. Surprisingly, some people could live positively during crisis. It becomes a model on ‘how can we live such a tough situation’. This study explored the positive effect of nostalgia on hope during crisis such as the COVID-19 pandemic. The research applied predictive-correlational quantitative method with 315 emerging adulthoods from Indonesia having an age range from 18-25 years. Hope was measured using The Herth Hope Index (HHI) developed by Herth, adapted to the Indonesian version in the COVID-19 pandemic context by the authors. Meanwhile nostalgia was measured using the Indonesian version of State Functions of Nostalgia Scale which was adapted by Abraham, Ali, Andangsari, and Hartanti from Hepper, Ritchie, Sedikides, and Wildschut. Result has shown that nostalgia had a significant positive effect on hope. It can be concluded that nostalgia significantly gave a positive effect on hope during the uncertainty situation like the COVID-19 pandemic. Reminiscing a nostalgic memory that happened before the pandemic occurred help young people to eliminate negative mood, increase self-esteem, increase a perception of social relationships, and develop a perception towards the meaning of life which make someone less anxious.
Sustainability Matters

The purpose of this study was to identify patterns of change in students’ awareness of, interest in and engagement with sustainability issues during the process of acclimatisation to their PBL engineering studies, and to look for differences between engineering disciplines with respect to these aspects. This study used a longitudinal qualitative approach with a theory-led thematic analysis. There were 16 participants in total, interviewed at 3 intervals during a period of 18 months at a faculty of engineering in Denmark. The authors found a pattern of increase in sustainability awareness, interest, and engagement throughout the three semesters of the study. Some differences between engineering disciplines were visible, especially between sustainability-oriented engineering and the others. Most students who increased their sustainability awareness and interest were also likely to engage further with the topic. That engagement built up from individual engagement, to professional engagement and for some, into institutional and public sphere engagement. The findings are timely given the pressure faced by engineering education to incorporate sustainability issues. It provides avenues for educating engineering graduates who will display interest, awareness, and engagement with sustainability issues. It suggests institutional engagement as a potential avenue to explore for engineering educators.
A Three-Dimensional low observable trajectory optimization method based on RCS

The method of finding an optimal aircraft trajectory to minimize the probability of detection by opponent radar detection systems is proposed.RCS data model,a three dimension(3D) aircraft and detection model,was established first.And then,the problem was described as an optimal control problem.The constraint functions were constructed by attitude control,trajectory constraints and boundary conditions.The cost function was formed to minimize both the probability of detection and the total flight time.After that,the continuous optimal control problem was parameterized to discrete nonlinear programming problem by Gauss pseudospectral method(GPM). Simulation results demonstrate the feasibility of the proposed method in low observable three-dimension trajectory optimization problem with monostatic radar and bistatic radar system,and it is also shown that the probability of detection and the exposure time decrease significantly.

The Bayes risk of Bayesian and non-Bayesian estimators are obtained for comparison. Illustrative examples, using real data are included.
Search for supersymmetry in pp collisions at s p ¼ 8 TeV in final states with boosted W bosons and b jets using razor variables

A search for supersymmetry in hadronic final states with highly boosted W bosons and b jets is presented, focusing on compressed scenarios. The search is performed using proton-proton collision data at a center-of-mass energy of 8 TeV, collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19 . 7 fb − 1 . Events containing candidates for hadronic decays of boosted W bosons are identified using jet substructure techniques, and are analyzed using the razor variables M R and R 2 , which characterize a possible signal as a peak on a smoothly falling background. The observed event yields in the signal regions are found to be consistent with the expected contributions from standard model processes, which are predicted using control samples in the data. The results are interpreted in terms of gluino-pair production followed by their exclusive decay into top squarks and top quarks. The analysis excludes gluino masses up to 1.1 TeV for light top squarks decaying solely to a charm quark and a neutralino, and up to 700 GeV for heavier top squarks decaying solely to a top quark and a neutralino.
The Importance of Pictorial Description in Consumer Decision-Making Involving Decoys

: According to the previous research about consumer behaviour, adding a decoy option to a choice set often increases the individual’s preference for one option over the other original option. The literature discusses the information format as one of the moderating factors with qualitative and pictorial information possibly weakening the decoy effect. To test this, this contribution uses the washing machine scenario of decoy effect previously examined where the decoy effect was found to not influence the consumer behaviour. In this paper, the experimental conditions were broadened when it comes to the image format accompanying the alternative description to examine the influence of specific images on the consumer choices to explain the previously reported failure to detect the decoy effect. In total, choices of 959 respondents from a set of the washing machines were collected and analysed using Chi-squared test. The current results indeed indicate the positive decoy effect when the product image was variable in the study design. However, no evidence was found that respondents’ choices would be directly influenced by the product image.
Tensorformer: Normalized Matrix Attention Transformer for High-quality Point Cloud Reconstruction

Surface reconstruction from raw point clouds has been studied for decades in the computer graphics community, which is highly demanded by modeling and rendering applications nowadays. Classic solutions, such as Poisson surface reconstruction, require point normals as extra input to perform reasonable results. Modern transformer-based methods can work without normals, while the results are less fine-grained due to limited encoding performance in local fusion from discrete points. We introduce a novel normalized matrix attention transformer (Tensorformer) to perform high-quality reconstruction. The proposed matrix attention allows for simultaneous point-wise and channel-wise message passing, while the previous vector attention loses neighbor point information across different channels. It brings more degree of freedom in feature learning and thus facilitates better modeling of local geometries. Our method achieves state-of-the-art on two commonly used datasets, ShapeNetCore and ABC, and attains 4% improvements on IOU on ShapeNet. Code can be accessed https://github.com/THHHomas/Tensorformer6.
Study on wettability behavior and wear resistance mechanism of ZTA-ceramic-reinforced HCCI composites

ABSTRACT Zirconia-toughened alumina (ZTA)-reinforced high-chromium cast iron (HCCI) composite materials were prepared using pressureless sintering method, and the effects of the type (titanium (Ti), nickel (Ni)) and content (10%, 12%) of active additives on the wettability and wear resistance were systematically studied. Result showed that the additive can enhance the wettability capacity between ZTA/HCCI composites interface, especially Ti, which reacted the chemical reaction and formed a transition layer in metallurgical combination. When the content of the Ti additive was 10%, the Brinell hardness (HB) of ZTA/HCCI composite was 573.1 N/mm2 at room temperature, and the wear-resistant properties were more than 3.8 times of pure HCCI. After thermal treatment, the HB and wear resistance of 10% Ti-ZTA/HCCI composites increased significantly which could reach 629.8 N/mm2 and were more than 4.3 times of the pure HCCI, respectively.
