title: Using Multisensory Haptic Integration to Improve Monitoring in the Intensive Care Unit

description: Alarm fatigue and medical alarm mismanagement reduces the quality of patient care and creates stressful work environments for clinicians. Here, the feasibility of a novel “pre-alarm” system that utilizes multisensory integration of auditory and haptic stimuli is examined as a possible solution. Three vital signs (heart rate, blood pressure, and blood oxygenation) were represented by three musically distinct sounds that were combined into soundscapes and progressed through five pre-alarm zones (very low to very high). Three haptic conditions were tested with the auditory stimulus to determine the best combination of auditory and haptic stimulation. Qualitative data was collected through surveys and the NASA TLX index. Alterations in frequency and timbre were most effective at transmitting information regarding changing vital sign zones with comparatively higher accuracy and quicker reaction time (RT), <i>p</i> p p The current study demonstrates that multisensory signals do not diminish the perception of transmitted information and suggest efficient training benefits over unimodal signals. Multisensory training may be beneficial over time compared to unisensory training due to a stronger consolidation effect. The potential integration of haptic input with existing auditory alarm systems and training is supported.

title: HUMAN4D: A Human-Centric Multimodal Dataset for Motions Immersive Media

description: We introduce HUMAN4D, a large and multimodal 4D dataset that contains a variety of human activities simultaneously captured by a professional marker-based MoCap, a volumetric capture and an audio recording system.nbsp;By capturing 2 female and 2 male professional actors performing various full-body movements and expressions, HUMAN4D provides a diverse set of motions and poses encountered as part of single- and multi-person daily, physical and social activities (jumping, dancing, etc.), along with multi-RGBD (mRGBD), volumetric and audio data.nbsp;Despite the existence of multi-view color datasets captured with the use of hardware (HW) synchronization, to the best of our knowledge, HUMAN4D is the first and only public resource that provides volumetric depth maps with high synchronization precision due to the use of intra- and inter-sensor HW-SYNC.nbsp;Moreover, a spatio-temporally aligned scanned and rigged 3D character complements HUMAN4D to enable joint research on time-varying and high-quality dynamic meshes.nbsp;We provide evaluation baselines by benchmarking HUMAN4D with state-of-the-art human pose estimation and 3D compression methods.nbsp;For the former, we apply 2D and 3D pose estimation algorithms both on single- and multi-view data cues.nbsp;For the latter, we benchmark open-source 3D codecs on volumetric data respecting online volumetric video encoding and steady bit-rates.nbsp;Furthermore, qualitative and quantitative visual comparison between mesh-based volumetric data reconstructed in different qualities showcases the available options with respect to 4D representations.nbsp;HUMAN4D is introduced to the computer vision and graphics research communities to enable joint research on spatio-temporally aligned pose, volumetric, mRGBD and audio data cues.The dataset and its code are available online.

title: High-level individuality in vocalizations of a well-known avian brood parasite: Asian koel (<i>Eudynamys scolopacea</i> L.)

description: The Asian koel (<i>Eudynamys scolopacea</i>) is a well-known brood parasitic bird that visits Pakistan every summer from India. This species produces at least five loud call types that are presumed to be used in territorial and mating behaviour. We noticed vocal differences among individuals in the wild and hypothesised that Asian koels produce individually distinct vocalizations. To test this, we recorded type 1 cooee calls, coe calls, type 1 coegh calls, type 2 coegh call and wurroo calls from 46 adult birds in the wild, and measured 15 different acoustic parameters, both spectral and temporal, for each vocalization type. We also measured the Potential of Individual Coding (PIC). Parameters having PIC values ≥1.1 were further analysed through stepwise cross-validated discriminant function analysis (DFA). The DFA accurately categorised 86.5% of the type 1 cooee calls, 95.7% of coe calls, 91.5% of the type 1 coegh calls, 82.2% of type 2 coegh calls and 83.3% of wurroo calls to the individuals from which these calls were recorded. Thus, consistent with our hypothesis, our results indicate that Asian koels produce individually distinct calls.

title: Social signatures in echolocation calls of a leaf-roosting bat, <i>Kerivoula furva</i>

description: Bats may use echolocation for social communication (e.g. group cohesion and individual recognition) although it has evolved primarily for orientation and foraging. This idea has been tested by using bats living in permanent roosts (e.g. caves) in large colonies. Here, we investigated social signatures in echolocation calls of a leaf-roosting bat, <i>Kerivoula furva</i>, which forms a small-sized group (2–10 individuals), roosts in furled banana leaves and switches roosts almost every day following foliation, but nevertheless, its group membership is largely fixed. We hypothesised that echolocation calls of <i>K. furva</i> differ significantly between groups and/or individuals, so that individuals can effectively find roost members, despite frequently changing roosts. Social structural and call analyses supported this hypothesis. Discriminant function analysis provided correct classifications significantly better than random ones, with 34.8% vs. 25% and 26.5% vs. 6.25% for group and individual signatures, respectively. Taken together with previous studies, our results suggest the possibility that, irrespective of the roost type, echolocation calls of bats generally contain enough information to be potentially useful for social communication. Future studies are encouraged to accumulate individual call data for a standardized comparison of context-dependent call signatures and to better understand social communication of bats.

title: Individual variation in two types of advertisement calls of Pacific tree frogs, <i>Hyliola (=Pseudacris) regilla</i>, and the implications for sexual selection and species recognition

description: Anuran advertisement calls play a fundamental role in social interactions related to reproduction, like territory defence and mate attraction. As such, advertisement calls are often shaped by natural and sexual selection. Therefore, to understand the evolution, function, and mechanisms of signal production and perception, it is important to characterise sources and patterns of variation in call properties. We recorded and analysed the two types of advertisement calls produced by Pacific tree frogs, <i>Hyliola regilla</i>: diphasic and monophasic calls. Specifically, we examined (i) the relationship between call properties and both body size and physical condition, (ii) patterns of within- and among-individual variation in call properties, and (iii) acoustic differences between diphasic and monophasic calls. While only one property of diphasic calls correlates with physical condition, spectral properties of both types of calls correlate with body size. Patterns of within- and among-individual variation were similar between call types and, overall, consistent with patterns reported for closely related species. Monophasic calls have lower frequencies, are delivered faster, and have higher call effort and duty cycle than diphasic calls. We discuss our results in relation to sexual selection and formulate hypotheses about the evolution, function, and mechanisms of acoustic communication in Pacific tree frogs.

title: Sounds produced by bottlenose dolphins (<i>Tursiops</i>): a review of the defining characteristics and acoustic criteria of the dolphin vocal repertoire

description: Bottlenose dolphins make many different sounds that have been recorded and described by researchers for over 60 years. This species, <i>Tursiops truncatus</i>, is arguably the most studied marine mammal. They have the ability to hear and produce sounds over a range of at least 150 kilohertz (kHz). Although the human hearing is limited in bandwidth to less than 20 kHz, dolphin sounds have historically been described as humans perceive them (e.g. whistles, squeals, buzzes, barks, quacks, pops, etc.). Often the same names have been used for different sounds and different names have been used for sounds that are apparently the same. In this review, we try and summarize the dolphin sound literature and provide standardized spectrograms where possible. Our goal is to provide a foundation for future research to build upon by providing a tool for identifying whether a sound has been described before. Novel sound types can then be recognized. Also, we encourage future studies that show when dolphins perceive two sound types as different. Detailed reports linking sound and behaviour are also essential. Only then can we have a complete idea of the dolphin repertoire and begin to understand how they use sound for communication.

title: Anti-predator function of not covering eggs in the initial phase of nesting in Grey Partridge <i>Perdix perdix</i>: a field experiment

description: <b>Capsule:</b> An experiment in the field supports the hypothesis that Grey Partridges <i>Perdix perdix</i> purposely expose their first laid eggs in order to test the predation risk at their nest site. <b>Aims:</b> To test the hypothesis that female Grey Partridges leave first laid eggs uncovered to assess the predation risk at their chosen nesting site. <b>Methods:</b> Four area-independent experiments with artificial nests were used. Predation risk was estimated by daily nest failure rate. Generalized linear mixed-effects models were used in statistical analysis. <b>Results:</b> We found that Grey Partridge females could predict nest site safety. At nest sites where the first uncovered egg was depredated, there was a higher predation risk for the whole clutch. <b>Conclusion:</b> Our data statistically support the hypothesis that leaving the first egg uncovered serves to provide a more conspicuous bait for potential predators and could be a female tactic for better recognizing predation risk at a nesting site. Thus, if the first uncovered egg is depredated, the female may start a new clutch elsewhere without wasting investment in the clutch at a site under high predation risk.

title: Optimal sampling design to survey riparian bird populations with low detection probability

description: <b>Capsule:</b> Linear censusing and occupancy models based on fixed sampling points are alternative widely used techniques to determine bird densities in riparian ecosystems, although it cannot be always properly executed. <b>Aims:</b> The aim is to assess the survey efficiency for river birds using occupancy models in contexts of impaired visibility owing to dense vegetation along the banks. <b>Methods:</b> We tested whether increasing sampling periods within each survey unit (point) at occupancy models would result in increasing detection probability values. We used two approaches in order to identify the ‘best’ design for White-throated Dippers <i>Cinclus cinclus</i> along forested river stretches: minimizing survey effort of standard single-season site occupancy modelling and exploratory power analysis. <b>Results:</b> With a detection probability of 0.26 (i.e. much lower than in previous studies), a design with 60 sites surveyed 10 min 6 times a year would be the option to survey White-throated Dippers in forested habitats if an acceptable power is required. Simulations further revealed the consistency of the results. <b>Conclusion:</b> We provide guidelines to establish a cost-effective survey design for any long-term monitoring citizen-based programme of a White-throated Dipper population when detection probabilities are low. A strength and novelty of the method is to take advantage of advanced probabilistic approaches (e.g. GRTS) to select the survey sites providing, among other major interests, a spatially balanced geographic coverage.

title: Structural study of letrozole and metronidazole and formation of self-assembly with graphene and fullerene with the enhancement of physical, chemical and biological activities

description: Letrozole and metronidazole are two commonly used drugs for the management of breast cancer and parasitic infections, respectively. This manuscript attempts to study their structure, geometry, search for stable conformers using relaxed potential energy scan, spectral properties, quantum mechanical properties like energy and reactivity descriptors, intra molecular electron transfer properties, non-linear properties etc using various computational tools. It is found that these compounds will form a self-assembly with graphene sheets and fullerenes and exhibit a surface-enhanced Raman spectra and enhancement in non-linear optical properties when compared to the single molecule. The electronic absorption behavior of the compounds was studied using TD-DFT method. Global chemical reactivity descriptors and activity sites toward electrophilic and nucleophilic attack have been discussed. Studies of intra molecular electron transfer gave information about the relative stability of the compounds. Molecular docking studies indicate that the pure compounds and their self-assemblies with graphene have excellent biological activities. Communicated by Ramaswamy H. Sarma
