Wing-Beat Frequency and Its Acoustics in Birds and Bats
Authors: Boonman Arjan , Yovel Yossi , Eitan Ofri 
Published: June 2020

SynopsisAnimal flight noise can serve as an inspiration to engineering solutions to wind-noise problems in planes or wind turbines. Here we investigate the acoustics of wingbeats in birds and bats by co-registering wing-movement in natural flight with acoustic noise. To understand the relationships between wing movement and acoustics, we conducted additional acoustic measurements of single moving wings and other moving surfaces with accurately tracked motion paths. We found a correlation between wing-surface area and the sound pressure level of wingbeats; with bats tending to produce lower levels than birds. Measuring moving wings in isolation showed that a downstroke toward a microphone causes negative sound pressure that flips back into positive pressure at the reversal to the upstroke. The flip back to positive pressure is unrelated to the action of the upstroke, but occurs when the downward motion is halted. If the microphone is positioned above the downward wingbeat, then sound pressure instead quickly rises during the downward motion of the wing. The phase pattern of the impulse created by the wingbeat varies systematically with recording-angle. The curvature of the wing appears to be a determinant of the average frequency of the acoustic impulse. Our findings can be used to predict the acoustics of smaller flying animals where repetition pitch of similar underlying impulses, repeated at much higher wingbeat-rates become dominant.
Fishing for euros: how mapping applications can assist in maintaining revenues under the Landing Obligation

Published: June 2020

Abstract
With the introduction of the Landing Obligation (LO) in EU fisheries, there is an increasing need for fishers to avoid unwanted catches while maximizing revenues. Improving understanding of the spatio-temporal dynamics of unwanted catches could assist the fishing industry optimize catches by altering where they fish. How following such advice relates to revenues and fishery dynamics requires more consideration. We take an existing hotspot mapping methodology and examine how it could be used to identify fishing opportunities under the LO in Irish (Celtic Sea) and Danish (North Sea and Skagerrak) demersal fisheries. We consider if fishing effort can be relocated to avoid unwanted catches while maintaining revenues. The value per unit effort of fishing activity in both areas was often linked to high catch rates of key demersal species (cod, haddock, hake, and whiting). Our analyses indicated, however, that there are options to fish in areas that could provide higher revenues while avoiding below minimum conservation reference size catches and choke species. This was evident across both case study areas demonstrating that hotspot mapping tools could have wide applicability. There does, however, remain a need to explore how the displacement of vessels may further alter species distributions and fleet economics.
Double Jump Phase Transition in a Soliton Cellular Automaton
Authors: Levine Lionel , Lyu Hanbaek , Pike John 
Published: June 2020

AbstractIn this paper, we consider the soliton cellular automaton introduced in [ 26] with a random initial configuration. We give multiple constructions of a Young diagram describing various statistics of the system in terms of familiar objects like birth-and-death chains and Galton–Watson forests. Using these ideas, we establish limit theorems showing that if the 1st $n$ boxes are occupied independently with probability $p\in (0,1)$, then the number of solitons is of order $n$ for all $p$ and the length of the longest soliton is of order $\log n$ for $p&lt;1/2$, order $\sqrt{n}$ for $p=1/2$, and order $n$ for $p&gt;1/2$. Additionally, we uncover a condensation phenomenon in the supercritical regime: for each fixed $j\geq 1$, the top $j$ soliton lengths have the same order as the longest for $p\leq 1/2$, whereas all but the longest have order $\log n$ for $p&gt;1/2$. As an application, we obtain scaling limits for the lengths of the $k^{\textrm{th}}$ longest increasing and decreasing subsequences in a random stack-sortable permutation of length $n$ in terms of random walks and Brownian excursions.
Slow Progress on UN Rapid Deployment: The Pitfalls of Policy Paradigms in International Organizations
Authors: Coleman Katharina P , Lundgren Magnus , Oksamytna Kseniya 
Published: June 2020

AbstractWhen reform negotiations in international organizations (IOs) produce limited substantive progress, the diagnosis is typically a lack of political will. We identify a different dynamic: in protracted negotiations, international policy paradigms can emerge that enshrine a politically realistic but incomplete issue definition and thereby focus the debate on a subset of policy instruments that do not fully address the underlying problem. We draw on the multilateral negotiations literature to show how policy paradigms—which are widely explored in Comparative Politics, but largely neglected in International Relations—can emerge even in heterogenous IOs, where deep cognitive cohesion is unlikely. The risk of negotiation failure incentivizes negotiators to adopt and maintain “achievable” issue and goal definitions, which over time are accepted as axiomatic by diplomats, IO officials, and policy experts. The resulting international policy paradigms help avoid institutional paralysis, but can also impede more ambitious reforms. To establish the empirical plausibility of this argument, we highlight the contemporary international policy paradigm of rapid deployment in UN peacekeeping, which focuses more on establishing an initial brigade-sized presence than on rapid deployment of the full peacekeeping force. Drawing on primary documents and interviews, we identify the roots of this First Brigade policy paradigm in reactions to the UN's failure to respond to the 1994 Rwandan genocide and trace its consolidation during UN reform negotiations in the 2000s and early 2010s. We also demonstrate that an alternative explanation of the paradigm as reflecting operational lessons-learned does not hold: a brigade-sized initial presence is rarely sufficient for mandate implementation, does not reliably speed up full deployment, and creates risks for peacekeepers. By highlighting the existence and impact of international policy paradigms, our study adds to scholarship on the role of ideas in International Relations and provides a novel perspective on reform negotiations in IOs.
Cannula complications using elastomeric infusers in Hospital in the Home
Authors: Ryan Damian , Miller Jennifer , Campbell Joanne 
Published: June 2020

Abstract

Objectives
Comparison of the short peripheral cannula (SPC) complication rate of patients with cellulitis receiving IV cefazolin via an elastomeric infuser with those receiving twice-daily bolus treatment (control group) in the Hospital in the Home service.

Methods
A randomized controlled study using elastomeric infuser versus bolus delivery of IV cefazolin via an SPC of patients referred to the Hospital in the Home service in the Northern Illawarra for treatment of cellulitis. A total of 104 patients were enrolled during the time period of May 2018 to January 2019. Primary outcome measures were SPC complications including phlebitis with a secondary outcome of patient satisfaction.

Results
A total of 104 patients enrolled. After randomization there were 60 in the infuser group and 44 in the bolus group. Patient characteristics of age, gender, weight and mobility were similar for the two groups. There was no statistically significant difference between the groups for the endpoint of cannula complication rates. Patient satisfaction scores showed patient acceptance of both forms of treatment.

Conclusions
This study suggests that using elastomeric infusers to deliver cefazolin via a short peripheral IV catheter has similar complication rates to traditional bolus delivery. Patients surveyed showed high levels of satisfaction with both forms of antibiotic delivery.

AbstractA new genus and new species of pilumnid crab, Ericiolumnus symbioticus (Decapoda: Brachyura), is described from the sponge Callyspongia Duchassaing & Michelotti, 1864 (Porifera: Callyspongiidae) in reefs in Lombok, Indonesia. The new taxon is characterized, among several characters, by the unusual shape of the carapace, which possesses sharp anterolateral teeth armed with secondary spinules, and prominently spinulous ambulatory legs. Another pilumnid, Pseudactumnus pestaeBalss, 1933, is shown to be a junior synonym of Actumnus asper (Rüppell, 1830). The pilumnid genus PseudactumnusBalss, 1933 is additionally synonymised with ActumnusDana, 1851. A review of symbiosis in Pilumnidae is also presented.
Patient comprehension of hip arthroscopy: an investigation of health literacy

Published: June 2020

Abstract
Several studies have demonstrated that patients have significant impairments in understanding their injury and appropriate course of management in orthopedic surgery. The purpose of this investigation is to determine if patients are able to obtain a fundamental understanding of the requisite care associated with hip arthroscopy. Any patient who elected to have hip arthroscopy was prospectively recruited to participate in the study. All patients were told they would be asked to complete a questionnaire about their surgery and post-operative instructions. The answers to each question of the questionnaire they would receive at the first post-operative visit were verbally given to each patient during the pre-operative visit. They were also given a post-operative instruction sheet on the day of surgery that contained answers to the questionnaire. At the first post-operative visit, all patients were then asked to complete a multiple-choice questionnaire prior to seeing the surgeon. A total of 56 patients (14 males, 42 females) were enrolled. All patients reported they had read the post-operative instruction sheet. The average number of correct answers was 6.5 ± 0.6 (95% CI 6 − 7) out of 11 questions (59% correct response rate ±18% [95% CI 52 − 66%]). Although we made significant pre-operative oral and written efforts to help patients achieve an elementary level of health literacy regarding their forthcoming hip arthroscopy, many patients did not achieve satisfactory comprehension. Even with instruction and information given verbally and physically (via post-operative instruction sheet) patients did not obtain satisfactory comprehension of their surgical procedure. New ways (through video, simplified cartoons or verbal explanations) must be considered in educating patients concerning surgical procedures to increase comprehension and health literacy.
New Light on the Emergence of Māturīdism: Abū Shakūr al-Sālimī (fifth/eleventh century) and his Kitāb al-Tamhīd fī bayān al-tawḥīd
Authors: Brodersen Angelika 
Published: June 2020

Abstract
The present paper focuses on the Arabic theological work al-Tamhīd fī bayān al-tawḥīd (‘Introduction to the Explanation of Monotheism’), authored by the Transoxanian scholar, Abū Shakūr al-Sālimī (fifth/eleventh century). A jurist and theologian, he belonged to the kalām-school in the succession of Abū Manṣūr al-Māturīdī (d. 333/944), and which, based on Ḥanafī tradition, forms the second pillar of the Sunni confession alongside the doctrines of Abū l-Ḥasan al-Ashʿarī (d. 324/935) and his followers. Despite increasing activities in the field of editions during the last few decades, details of Māturīdī speculative theology (kalām) still remain insufficiently studied. This deficiency applies, on the one hand, to the utilization of texts, partially or not yet available in text-critical and analytically focused editions. On the other hand, a profound and pressing need for systematic research remains, particularly with regards to the relationship between Māturīdism and Ashʿarism, given that the latter has been studied in much greater detail. Against this background, al-Sālimī is presented in his historical and intellectual milieu. It is shown that his treatise is in the Ḥanafī–Māturīdī tradition, but his doctrines sometimes differ from other Māturīdī teachings. Subsequently, some key topics of the Tamhīd are addressed. A special focus is on the beginning of the dispute between Māturīdī theologians and the Ashʿariyya, where issues of epistemology, prophecy, the doctrine of God’s names and attributes, and the conception of faith that serve as typical examples of Ḥanafī jurisprudence and theology are also treated. Finally, a case study illuminates important issues at the heart of Māturīdī theology, as well as the integration of juridical topics into kalām. Through this approach, this paper intends to introduce the text as a valuable source for the study of Sunni theology in a more comprehensive sense than has previously been considered.
Does latitudinal migration represent an advantage in the decrease of ectoparasitic loads in Leptonycteris yerbabuenae (Chiroptera)?

Abstract
Latitudinal migration increases fitness of migrants by allowing them to exploit favorable conditions in nonadjacent geographic regions. Other consequences also may follow, such as interactions with parasites. Migrants may have lower parasite prevalence and abundance than resident individuals because of their ability to abandon infested areas or due to mortality of highly infested hosts. To further understand whether variation in ectoparasite loads is influenced by migration, we investigated whether prevalence and abundance of two species of obligate ectoparasites, the wing mite Periglischrus paracaligus (Mesostigmata: Spinturnicidae) and the bat fly Nycterophilia coxata (Diptera: Streblidae, Nycterophiliinae), of the lesser long-nosed bat, Leptonycteris yerbabuenae, varied between migratory and resident populations throughout their range in Mexico. We examined the presence or absence of migratory behavior, as well as sex and reproductive status of the host because ectoparasitism differentially affects the sexes. Our results showed that the prevalence of both ectoparasites did not vary between migrant and resident females or males, but abundance of the wing mite P. paracaligus was lower in migrant females compared with resident females, with an important influence from the reproductive status of the host. A partial negative relationship between ectoparasite loads and latitudinal migration therefore was demonstrated.
Organizational and Individual Innovation Decisions in an Interorganizational System: Social Influence and Decision-Making Authority
Authors: Fu Jiawei Sophia , Shumate Michelle , Contractor Noshir 
Published: June 2020

AbstractThis study examines the processes of complex innovation adoption in an interorganizational system. It distinguishes the innovation adoption mechanisms of organizational-decision-makers (ODMs), who make authority adoption decisions on behalf of an organization, from individual-decision-makers (IDMs), who make optional innovation decisions in their own work practice. Drawing on the Theory of Reasoned Action and Social Information Processing Theory, we propose and test a theoretical model of interorganizational social influence. We surveyed government health-care workers, whose advice networks mostly span organizational boundaries, across 1,849 state health agencies in Bihar, India. The collective attitudes of coworkers and advice network members influence health-care workers’ attitudes and perceptions of social norms toward four types of innovations. However, individuals’ decision-making authority moderates these relationships; advisors’ attitudes have a greater influence on ODMs, while perceptions of social norms only influence IDMs. Notably, heterogeneity of advisors’ and coworkers’ attitudes negatively influence IDMs’ evaluations of innovations but not ODMs’.

Abstract
Most cases of peritoneal dissemination of colorectal cancers are from T3 or T4 tumors. A 61-year-old woman was admitted for examination of a positive fecal occult blood test. Colonoscopy showed an ascending colon tumor that was diagnosed as an adenocarcinoma with massive submucosal invasion. Imaging modality revealed numerous nodules throughout the abdominal cavity. Peritoneal dissemination of the ascending colon or ovarian cancer and pseudomyxoma peritonei were considered in the preoperative differential diagnoses, and laparoscopic ileocecal resection was performed. Intraperitoneal observation revealed numerous white nodules in the peritoneum, omentum and Douglas fossa. Both the nodules and tumor were diagnosed as mucinous carcinoma based on a pathology report. The tumor invasion depth was limited to muscularis propria, and no regional lymph node metastasis was detected. Peritoneal dissemination of the ascending colon cancer was considered. We report a rare case of multiple peritoneal dissemination of T2 colorectal cancer without lymph node metastases.
Galaxy mass profiles from strong lensing II: The elliptical power-law model
Authors: O’Riordan C M , Warren S J , Mortlock D J 
Published: June 2020

ABSTRACT
We present a systematic analysis of the constraints σγ on the mass profile slope γ obtainable when fitting a singular power-law ellipsoid model to a typical strong lensing observation of an extended source. These results extend our previous analysis of circular systems, Paper I. We draw our results from 676 mock observations covering a range of image configurations, each created with a fixed signal to noise ratio S = 100 in the images. We analyse the results using a combination of theory and a simplified model which identifies the contribution to the constraints of the individual fluxes and positions in each of the lensed images. The main results are: 1. For any lens ellipticity, the constraints σγ for two image systems are well described by the results of Paper I, transformed to elliptical coordinates; 2. We derive an analytical expression for σγ for systems with the source aligned with the axis of the lens; 3. For both two-image systems and aligned systems, σγ is limited by the flux uncertainties; 4. The constraints for off-axis four-image systems are a factor of two to eight better, depending on source size, than for two-image systems, and improve with increasing lens ellipticity. We show that the constraints on γ in these systems derive from the complementary positional information of the images alone, without using flux. The complementarity improves as the offset of the source from the axis increases, such that the best constraints σγ &lt; 0.01, for S = 100, occur when the source approaches the caustic.
Study of the departures from LTE in the unevolved stars infrared spectra

Published: June 2020

ABSTRACT
We present a study of departures from Local Thermodynamic Equilibrium (LTE) in the formation of infrared (IR) lines of Na i, Mg i, Al i, S i, K i, and Sr ii in unevolved stars of spectral types F, G, K and metallicities around the solar metallicity. The purpose of this investigation is to identify lines of these species that can be safely treated with the LTE approximation in the IR spectra of these types of stars. We employ a set of 40 stars observed with the GIANO spectrograph at the 3.5 m Telescopio Nazionale Galileo and previously investigated by Caffau et al. We were able to identify many lines that can be treated in LTE for all the above-mentioned species, except for Sr ii. The latter species can only be studied using three lines in the J band, but all three of them display significant departures from LTE. With our small-size, but high-quality sample, we can determine robustly the trends of the abundance ratios with metallicity, confirming the trends apparent from a sample that is larger by several orders of magnitude, but of lower quality in terms of resolution and S/N ratio.
Environments of dwarf galaxies with optical AGN characteristics
Authors: Kristensen Mikkel T , Pimbblet Kevin , Penny Samantha 
Published: June 2020

ABSTRACT
This study aims to explore the relation between dwarf galaxies (M* ≤ 5 × 109 M⊙) with active galactic nuclei (AGNs) and their environment by comparing neighbourhood parameters of AGN and non-AGN samples. Using the NASA-Sloan Atlas, both the local environment and the immediate environment of dwarf galaxies with z ≤ 0.055 are analysed. Of the 145 155 galaxies in the catalogue, 62 258 of them are classified as dwarf galaxies, and by employing two AGN selection methods based on emission-line fluxes (BPT and WHAN), 4476 are found to have AGN characteristics in their optical spectra. Regardless of selection method, this study finds no discernible differences in environment between AGN and non-AGN host dwarf galaxies and these results indicate that environment is not an important factor in triggering AGN activity in dwarf galaxies. This is in line with existing literature on environments of regular galaxies with AGNs and suggests universality in terms of reaction to environment across the mass regime. The biases of AGN selection in low-mass galaxies, and the biases of different measures of environment are also considered. It is found that there are several mass trends in emission-line ratios and that the SDSS fibre covers galaxies non-uniformly with redshift. These biases should be accounted for in future work by possibly including other wavelength regimes or mass weighting of emission-line ratios. Lastly, a discussion of the environment estimation methods is included since they may not gauge the desired properties due to factors such as time delay or using loosely constrained proxy parameters.
