On-body sensing technologies and signal processing techniques in addressing safety of human machine collaboration
Authors: Haratian Roya 
Published: November 2024

Abstract
Safety is a challenge in human machine collaboration despite of the advantages in achieving efficiency, cost reduction and productivity in a collaborative scenario between human and machine/robot. During collaboration with machines, the user might not be able to follow the collaborative tasks as expected due to the cognitive burden causing potential safety concerns such as collision. Addressing this challenge, the aim of this paper is to explore the potential of on-body sensing systems in study of user experience and the psychological condition during the collaboration between machines and human. As the psychological condition is reflected in physiological signals, sensing technologies and signal processing techniques to extract features from physiological signals are explored with applicability in human machine collaboration scenarios. An experiment is designed utilising an industrial collaborative robot arm while quantitative and qualitative data is gathered for this purpose exploring the problem to study user experience and impact of mental strain and cognitive workload on user performance and experience during human machine collaboration. Results show that an adaptive machine to user experience measured by on-body sensing systems during the collaboration has the potential to address safety in human machine collaboration while improving performance and user experience.

Published: November 2024

AbstractThis study aims to analyse the behaviour of asphalt concrete produced from recycled plastic-modified bitumen. This particular production process is known as the wet method, which involves the blending of low melting point recycled plastics, mostly polyolefins, in hot bitumen before mixing with preheated aggregate. Based on a comprehensive research study that investigated several recycled plastics for the wet method, two common low melting point plastics from two different collection streams were evaluated: a low-density polyethylene from post-industrial recycling operations and a source of commingled plastic (polyethylene and polypropylene) from the collection of post-consumer plastics. Plastic-modified bitumen was produced with different recycled plastic contents ranging from 0.5 to 6% of the bitumen weight. First, the storage stability of the plastic-modified bitumen was evaluated. Then, asphalt mixes were produced using the plastic-modified bitumen. The testing scheme included measurements of the compactability and densification behaviour of the mixes, moisture resistance, viscoelastic behaviour via the flexural stiffness test, IDEAL-CT test to evaluate cracking tolerance, fatigue resistance through the four-point bending beam test, and rutting resistance via Hamburg wheel tracking. The study found that adding a high plastic content significantly reduced the storage stability of the plastic-modified bitumen. Adding plastic was found to have a minor impact on the compactability, while it reduced the moisture resistance with increasing plastic addition and modified the viscoelastic behaviour of the asphalt mixtures. Finally, the study found that plastic provided benefits to the cracking and rutting resistance of asphalt mixtures to different extents depending on the plastic type and plastic content.

Abstract
Background
Airway management is a critical skill required in the Emergency Department (ED). We conducted an observational airway registry-based study to report the practice and outcome of endotracheal intubations in the ED at the national referral hospital in Thimphu.

Methods
All patients who were intubated in the ED and recorded on the registry data form between May 2020 to November 2022 were studied. Variables such as indications, type of physician performing intubations, success rate, complications, medications, and disposition were captured. Descriptive analysis was presented in frequency and proportions.

Results
There were a total of 336 intubations during the study period. First pass success rate was 87.80% and complication rate was 19.64%. 40 patients (11.90%) needed a second attempt and only 1 patient required a third attempt. Most intubations were performed by emergency medicine (EM) residents (54.17%), followed by medical officers (37.8%). Emergency Physician (EP) performed the least number of intubations, 27 (8.04%). During preoxygenation, 64.5% (n = 217) patients received positive pressure ventilations and 119 (35.42%) did not.

Conclusion
Physicians working in the ED are the primary airway provider. First pass success rate was 87.80%. 40 patients (11.90%) needed a second attempt and only 1 patient required a third attempt.
Behavioral strategies for reducing corruption: from regulation to choice architecture
Authors: Hortal Alejandro , Pérez Martínez Armenio 
Published: November 2024

Abstract
Traditionally, corruption is seen as a rational pursuit of profit, focusing on personal gain. However, this view overlooks other influences. This paper focuses on the behavioral aspects of corruption, providing a deeper understanding of its complexities, and addressing the factors overlooked by conventional approaches. Reviewing some of the literature, we highlight how researchers have approached corruption from the perspective of behavioral sciences. Additionally, we examine how the emerging discipline of Behavioral Public Policy (BPP) employs innovative methods to reduce corrupt practices, offering new strategies that transcend traditional perspectives. Our paper innovates by demonstrating how corruption can be reduced by substituting traditional regulations with nonregulatory tools like nudges and sludge audits, or by leveraging digital choice architectures to minimize human-to-human interactions, known corruption enablers. By reducing regulations and administrative red tape, and introducing digital frameworks, these tools simplify processes minimizing opportunities for corrupt behavior. In this paper, we aim to infuse corruption research with a behavioral twist, a digital approach, and a deregulatory perspective, offering policymakers an alternative path to foster transparency, accountability and ethical governance. While this approach will not completely eradicate corruption, it strives to show how BPP can reduce its occurrences.

Abstract

Background
The COVID-19 pandemic created stressors to daily living, leading to increased mental health problems. It is important to assess the influence of COVID-19 pandemic on mental health, specifically anxiety.

Objectives
The goal was to determine the prevalence and sociodemographic, clinical, and other correlates of likely Generalized Anxiety Disorder (GAD) among study subjects in Ghana.

Design
This study employed a cross-sectional approach, using an online survey administered primarily through social media platforms. The survey questions included the GAD-7 scale, which was used to assess likely GAD in respondents. Data were analyzed using descriptive statistics, chi-square tests, and logistic regression analysis.

Participants
Overall, 756 respondents completed the survey, mainly from Ashanti and Greater Accra, which were the hardest hit by COVID-19.

Results
The prevalence of likely GAD in our sample was 7.6%. Gender, loss of job due to COVID-19, and seeking mental health counseling were independently associated with increased likelihood of GAD.

Conclusions
The findings suggest that women, those who lost their jobs due to the COVID-19 pandemic, and those who sought mental health counseling were more likely to experience moderate to high anxiety symptoms as a result of the COVID-19 pandemic. Priority must be attached to psychological support measures for members of these groups.

Published: November 2024

Abstract
Femtosecond oscillators with gigahertz (GHz) repetition rate are appealing sources for spectroscopic applications benefiting from the individually accessible and high-power comb line. The mode mismatch between the potent pump laser diode (LD) and the incredibly small laser cavity, however, limits the average output power of existing GHz Kerr-lens mode-locked (KLM) oscillators to tens of milliwatts. Here, we present a novel method that solves the difficulty and permits high average power LD-pumped KLM oscillators at GHz repetition rate. We propose a numerical simulation method to guide the realization of Kerr-lens mode-locking and comprehend the dynamics of the Kerr-lens mode-locking process. As a proof-of-principle demonstration, an LD-pumped Yb:KGW oscillator with up to 6.17-W average power and 184-fs pulse duration at 1.6-GHz repetition rate is conducted. The simulation had a good agreement with the experimental results. The cost-effective, compact and powerful laser source opens up new possibilities for research and industrial applications.

Published: November 2024

Abstract
Er:CaF2 crystals are crucial gain media for producing 3 μm mid-infrared (MIR) lasers pumped by 976 nm continuous-wave (CW) lasers owing to their low phonon energy and high conversion efficiency. This study investigated the damage characteristics and mechanism of Er:CaF2 crystals irradiated with a 976 nm CW laser. The laser-induced damage threshold of Er:CaF2 crystals with different Er3+ doping levels was tested; the damage morphology consists of a series of regular 70° cracks related to the angle of the crystal slip system on the surface. A finite-element model was used to calculate the temperature and stress fields of the crystals. The results indicated that the damage can be attributed to surface tensile stresses caused by the temperature gradient, and crystals with higher doping concentrations were more susceptible to damage owing to stronger light absorption. These findings provide valuable insights into the development of high-power MIR lasers.
Ediacaran paleobiology and biostratigraphy of the Nama Group, Namibia, with emphasis on the erniettomorphs, tubular and trace fossils, and a new sponge, Arimasia germsi n. gen. n. sp.

Published: November 2024

AbstractEdiacaran fossils, obtained in stratigraphic context in 1993, 1995, and 1996, with the assistance of A. Seilacher, IGCP project 320 scientists, and the Geological Survey of Namibia, are described for the first time. Most are from the Kliphoek and Buchholzbrunn members of the Dabis Formation and the Huns and Spitskop members of the Urusis Formation, Witputs subbasin, but a significant number, including Pteridinium, are from the Kliphoek Member, Zaris Formation, and the Neiderhagen Member, Nudaus Formation, north of the Osis arch, which separates the two subbasins. We extend the stratigraphic ranges and geographic distributions of several important taxa, including Archaeichnium, Ernietta, Pteridinium, and Swartpuntia, provide reassessments of the paleobiology of these and other organisms, and describe a new sponge—possibly an unmineralized archaeocyath—Arimasia germsi n. gen. n. sp. We also describe and illustrate various ichnofossils (including the oldest known traces from the Nama Group), narrow down the first appearance of Treptichnus in the Nama succession, and reinforce the idea that there was a prolific infauna of micrometazoans during the latest Ediacaran by naming and describing previously reported microburrows found on the surfaces of gutter casts as Ariichnus vagus n. igen. n. isp.UUID: http://zoobank.org/8c267425-135a-4b0a-98b6-cf726515cbf2
HOW MANY TRIANGLES CAN A GRAPH HAVE?
Authors: KITTIPASSORN TEERADEJ , POPIELARZ KAMIL 
Published: November 2024

Abstract
We investigate the set

$T_{n}$

of the possible number of triangles in a graph on n vertices. The first main result says that every natural number less than

$\binom {n}{3} - (\sqrt {2}+o(1) )n^{3/2} $

belongs to

$T_{n}$

. On the other hand, we show that there is a number

$m = \binom {n}{3}-( \sqrt {2} +o(1))n^{3/2}$

that is not a member of

$T_{n}$

. In addition, we prove that there are two interlacing sequences

$\binom {n}{3} - ( \sqrt {2} + o(1) )n^{3/2} = c_{1} \le d_{1} \le c_{2} \le d_{2} \le \cdots \le c_{s} \le d_{s} = \binom {n}{3}$

with

$| c_{t} - d_{t}| = n-2-\binom {s - t +1}{2}$

such that

$( c_{t}, d_{t} ) \cap T_{n} = \emptyset $

for all t. Moreover, we obtain a generalisation of these results for the set of the possible number of copies of a connected graph H in a graph on n vertices.

Playful framings of social robots in dementia care: reconsidering the principle of transparency in interactions with robot animals
Authors: Iversen Clara , Persson Marcus , Redmalm David 
Published: November 2024

Abstract
Research on social robots in dementia care has focused on their effects, for example in relation to the patients’ wellbeing or the care-givers’ working environment. Such approaches to social robots treat them as stable objects with a singular function. Combining social gerontology with social studies of science, the current study offers a new angle by asking: How do patients and care-givers in care homes for older people establish a shared definition of the situation in interactions involving robot animals? Drawing on ethnography and multimodal conversation analysis of 211 minutes of video recordings in two care homes in Sweden, we demonstrate the embodied work by which participants in interactions establish activities with robot animals. In contrast to the ideal of transparency in social robotics, we show that a central affordance of the robots is their vagueness, which allows for their inclusion in playful interactions. Playful framings of the robots highlight their social functions and downplay care-giver–patient asymmetries. However, situations where patients resist a playful frame actualise a dilemma of social inclusion, on the one hand, and the right to not participate in play, on the other. Showing this, the article contributes to knowledge on how people age with technology; in particular, it draws attention to the limits of an ideal of transparency when social robots are included in dementia care.

Abstract
Uncaria rhynchophylla (Rubiaceae), a woody liana with significant medicinal value, has been used as a traditional Japanese and Chinese medicine. While effective seed production is required for breeding and efficient seedling production, the physiology of sexual reproduction remains largely unknown in this species. Therefore, we first observed the flowering behaviour, and next attempted artificial pollination using flowering individuals in a greenhouse. In this study it became clear that this species sets seeds by allogamy, but not by autogamy. The obtained seeds showed about a 90% germination rate. We also examined seed desiccation tolerance and storage conditions which are important to preserve the genetic resources. Seeds of this species were found to have a characteristic of the orthodox type, having high desiccation tolerance. Seeds after 6 months of storage at + 22, −20 and −160°C showed comparable germination rates to the seeds before storage.
Walter Lippmann: an institutionalist for our times?
Authors: Hargreaves Heap Shaun P. , Lewis Paul 
Published: November 2024

Abstract
Although Lippmann's The Good Society was written to address the crisis in liberal democracies in the 1930s, we argue that it offers a novel and plausible institutionalist account of the productivity slowdown and the increase in the experience of insecurity that has characterised most liberal democracies over the last 20–40 years. Central to Lippmann's account is a Smithian-institutionalist model of growth where property rights have to evolve both to encourage continued levels of risk taking in the face of new uncertainties and also to offset new sources of unequal bargaining power that the very process of growth itself creates. When property rights fossilise and fail to evolve, as in the 1930s and plausibly also now, productivity growth slows down, insecurity rises, and illiberal political creeds prosper. To avoid this, Lippmann's analysis suggests that property rights have to change to re-energise risk taking and to offset the new sources of unequal bargaining power. For example, in current circumstances, new ‘positive’ property rights arising from the development of social insurance might encourage risk taking and new ‘negative’ property rights in personal data might help offset the new sources of unequal bargaining power that have emerged.
Substrate integrated waveguide differential antenna for full duplex applications
Authors: Srivastava Gunjan , Singh Shalini 
Published: November 2024

Abstract
This paper presents a substrate-integrated waveguide (SIW) differential antenna for full duplex applications. The proposed antenna consists of two square SIW cavities named as outer and inner. The inner cavity is nested into the outer cavity. The outer cavity is differentially excited with a pair of coaxial feed lines, while the inner square patch is orthogonally excited with another pair of differential coaxial feed lines. This orthogonal feeding arrangement results in high isolation between the differential ports. The modified hybrid TE130/310 mode of the outer cavity radiates through a pair of arc-shaped slots at 9.35 GHz, while the TM01 mode of the inner square patch is responsible for the radiations at 8.65 GHz. The proposed antenna prototype is fabricated and measured for validation. Moreover, the designed antenna has a front-to-back ratio better than 22 dB and measured maximum gain values of 6.1 dBi and 7.6 dBi at 8.65 GHz (Port 2 ON) and 9.35 GHz (Port 1 ON), respectively.

Abstract
Insomnia’s impact on psychological functioning is known to increase suicide risk. The underlying mechanisms of this association are unclear. This study explored psychological factors including depression, emotion dysregulation, perceived burdensomeness and thwarted belongingness as possible mechanisms in the association between insomnia and suicidal ideation in a nationally representative sample for age, sex and race in the United States. Participants (N = 428) completed a Qualtrics survey of demographics, Insomnia Severity Index, Difficulties in Emotion Regulation Scale, Interpersonal Needs Questionnaire, Frequency of Suicidal Ideation Inventory and PROMIS-Depression and PROMIS-Anxiety short forms. Regression analyses and structural equation modeling were used. Insomnia severity was associated with greater suicidality (p < 0.001, CI = 0.19–0.31). When accounting for depression severity, emotion dysregulation and perceived burdensomeness fully mediated insomnia–suicidal ideation frequency association (β = 0.04, p = 0.045; β = 0.24, p < 0.001). Insomnia has major implications on psychological functioning, which may serve as mechanisms through which insomnia confers risk for suicidality. Our model posits that insomnia prevents regional sleep restoration in brain regions involved in psychological functioning, thereby conferring risk for suicidality. Insomnia may be an ideal upstream target for reducing suicidality and its risk factors, including depression, emotion dysregulation and perceived burdensomeness.
Integrating sequential applications of residual and postemergence herbicides for controlling Carolina redroot (Lachnanthes caroliniana) in cranberry beds
Authors: Besançon Thierry E. , Erndwein Lindsay 
Published: November 2024

Abstract
Carolina redroot (LAHTI) is a perennial weed of New Jersey cranberry beds. It is associated with “stand opening” areas that result from fairy ring dieback or other conditions of natural and anthropogenic origin. LAHTI accounts for significant yield reduction through direct competition with cranberry for nutritional resources. Field experiments were conducted from 2017 to 2022 on ‘Ben Lear’ and ‘Early Black’ cranberry beds in Chatsworth, NJ, to determine 1) the efficacy of residual herbicides labeled for use on cranberry, and subsequently, 2) to evaluate the value of overlapping preemergence applications of napropamide and postemergence applications of mesotrione for LAHTI control while minimizing crop phytotoxicity. Treatments in the first experiment included preemergence applications of dichlobenil or norflurazon at 2.2 and 4.5 kg ha−1 and napropamide a 6.7 kg ha−1. In the second trial, napropamide was applied preemergence annually to plots at 6.7 or 10.1 kg ha−1 either as a single or as two equally or unequally split applications spaced 30 d apart, followed by or not followed by mesotrione applied postemergence at 280 g ha−1 when LAHTI leaves emerged above the cranberry canopy. The preemergence herbicides dichlobenil applied at 4.5 kg ha−1 and napropamide provided ≥48% LAHTI control and ≥40% LAHTI biomass reduction 112 d after treatment (DAT), whereas norflurazon had no significant effect on LAHTI biomass. Less than 4% of crop injury and liquid formulation adapted to chemigation identified napropamide as an effective preemergence herbicide for LAHTI control. In the second trial, napropamide applied at 10.1 kg ha−1 followed by an application of mesotrione reduced LAHTI biomass by ≥73%. Splitting napropamide application reduced yield by 36% and berry weight by 12% compared with a single application at the dormant stage. Compared with the nontreated control, a single napropamide application at 10.1 kg ha−1 followed by an application of mesotrione increased yield by 38%. Information derived from these studies is already being used by growers to enhance the productivity and profitability of New Jersey cranberry fields.
