Design and development of an open-source framework for citizen-centric environmental monitoring and data analysis
Authors: Mahajan Sachit
Published: August 2022

Cities around the world are struggling with environmental pollution. The conventional monitoring approaches are not effective for undertaking large-scale environmental monitoring due to logistical and cost-related issues. The availability of low-cost and low-power Internet of Things (IoT) devices has proved to be an effective alternative to monitoring the environment. Such systems have opened up environment monitoring opportunities to citizens while simultaneously confronting them with challenges related to sensor accuracy and the accumulation of large data sets. Analyzing and interpreting sensor data itself is a formidable task that requires extensive computational resources and expertise. To address this challenge, a social, open-source, and citizen-centric IoT (Soc-IoT) framework is presented, which combines a real-time environmental sensing device with an intuitive data analysis and visualization application. Soc-IoT has two main components: (1) CoSense Unit—a resource-efficient, portable and modular device designed and evaluated for indoor and outdoor environmental monitoring, and (2) exploreR—an intuitive cross-platform data analysis and visualization application that offers a comprehensive set of tools for systematic analysis of sensor data without the need for coding. Developed as a proof-of-concept framework to monitor the environment at scale, Soc-IoT aims to promote environmental resilience and open innovation by lowering technological barriers.
Critical hydraulic gradient and fine particle migration of sand under upward seepage flow
Authors: Wang Bo , Chen Long-wei , Niu Zhen
Published: August 2022

In order to study the mechanism of seepage-induced geotechnical damage and characteristics of fine particle migration in sandy soil, a one-dimensional upward seepage test device was used and a series of upward seepage flow tests of sand were conducted. In these experiments, the permeability, fine particle migration and redistribution under different hydraulic gradients were investigated. The results show that local hydraulic gradient in the sand sample is larger than the critical hydraulic gradient calculated by the Terzaghi’s Equation. The seepage force will induce the fine soil particles to migrate along water flow direction and then cause the redistribution and reconsolidation of sand particles. Under the test condition, fine particles (< 0.075 mm) and fine sand particles (0.075–0.25 mm) dominate in the lost soil particles. Soil particles larger than 0.6 mm are hardly to lose.
Cloud and snow detection of remote sensing images based on improved Unet3+
Authors: Yin Meijie , Wang Peng , Ni Cui , Hao Weilong
Published: August 2022

Cloud detection is an important step in remote sensing image processing and a prerequisite for subsequent analysis and interpretation of remote sensing images. Traditional cloud detection methods are difficult to accurately detect clouds and snow with very similar features such as color and texture. In this paper, the features of cloud and snow in remote sensing images are deeply extracted, and an accurate cloud and snow detection method is proposed based on the advantages of Unet3+ network in feature fusion. Firstly, color space conversion is performed on remote sensing images, RGB images and HIS images are used as input of Unet3+ network. Resnet 50 is used to replace the Unet3+ feature extraction network to extract remote sensing image features at a deeper level, and add the Convolutional Block Attention Module in Resnet50 to improve the network’s attention to cloud and snow. Finally, the weighted cross entropy loss is constructed to solve the problem of unbalanced sample number caused by high proportion of background area in the image. The results show that the proposed method has strong adaptability and moderate computation. The mPA value, mIoU value and mPrecision value can reach 92.76%, 81.74% and 86.49%, respectively. Compared with other algorithms, the proposed method can better eliminate all kinds of interference information in remote sensing images of different landforms and accurately detect cloud and snow in images.
Deep belief rule based photovoltaic power forecasting method with interpretability
Authors: Han Peng , He Wei , Cao You , Li YingMei , Zhang YunYi
Published: August 2022

Accurate prediction of photovoltaic (PV) output power is of great significance for reasonable scheduling and development management of power grids. In PV power generation prediction system, there are two problems: the uncertainty of PV power generation and the inexplicability of the prediction result. The belief rule base (BRB) is a rule-based modeling method and can deal with uncertain information. Moreover, the modeling process of BRB has a certain degree of interpretability. However, rule explosion and the inexplicability of the optimized model limit the modeling ability of BRB in complex systems. Thus, a PV output power prediction model is proposed based on a deep belief rule base with interpretability (DBRB-I). In the DBRB-I model, the deep BRB structure is constructed to solve the rule explosion problem, and inefficient rules are simplified by a sensitivity analysis of the rules, which reduces the complexity of the model. Moreover, to ensure that the interpretability of the model is not destroyed, a new optimization method based on the projection covariance matrix adaptation evolution strategy (P-CMA-ES) algorithm is designed. Finally, a case study of the prediction of PV output power is conducted to illustrate the effectiveness of the proposed method.

Authors: Assouly Kelly K. S. , Arts Remo A. G. J. , Graham Petra L. , van Dijk Bas , James Chris J.
Published: August 2022

Tinnitus is a common symptom in cochlear implant (CI) recipients. There is no clear evidence of the influence of tinnitus on hearing-related quality of life (QoL) in this population. The aim of this study was to assess the relationship between hearing-related QoL measured by the Speech, Spatial and Qualities of Hearing scale (SSQ12) and tinnitus annoyance or perceived change in tinnitus annoyance after cochlear implantation. The study sample consisted of 2322 implanted adults across France, Germany, Ireland, Italy, the Netherlands, Sweden and the United Kingdom. Information relating to QoL measured using the SSQ12 and tinnitus annoyance and change in tinnitus annoyance, assessed using single-item questions, were collected one or more years post-implantation. The relationship between SSQ12 score and tinnitus annoyance or change in tinnitus annoyance was analysed using linear models adjusted for age and unilateral versus bilateral implants. Tukey pairwise tests were used to compare mean SSQ12 scores across levels of tinnitus annoyance and changes. Tinnitus prevalence was 33.9% post-implantation. Recipients with tinnitus had a significantly lower SSQ12 score than recipients without tinnitus. SSQ scores varied significantly with tinnitus annoyance, age and unilateral versus bilateral implants. Overall, CI recipients who experienced less bothersome tinnitus reported better hearing-related QoL. Healthcare professionals should be aware of the influence of tinnitus on CI recipients’ hearing to manage patient expectations.

Published: August 2022

Purpose:

Military service personnel are at increased risk for developing tinnitus due to heightened exposure to acoustic trauma. The auditory disorder is the leading service-connected disability among veterans and is highly comorbidly diagnosed with posttraumatic stress disorder (PTSD). The biopsychosocial model illustrates that chronic health conditions are exacerbated or maintained by psychiatric distress. Therefore, alleviation of such psychiatric distress can have beneficial impacts on health conditions, such as tinnitus. The aim of this study was to determine whether individuals with both disorders who receive evidence-based therapy for PTSD will experience decreases in both PTSD and tinnitus-related distress.

Method:

Veterans with comorbid bothersome tinnitus and PTSD received cognitive processing therapy and were assessed for PTSD, tinnitus-related distress, and depression at baseline and 1 month posttreatment follow-up.

Results:

At posttreatment follow-up, participants demonstrated significant decreases in PTSD symptoms compared to their baseline scores. Participants also demonstrated decreased tinnitus-related distress and depression, with high effect sizes.

Conclusions:

This pilot study demonstrated that clinical management addressing psychiatric distress, as associated with PTSD, may simultaneously provide benefit for patients with bothersome tinnitus. Although not statistically significant due to the small sample size, large effect sizes indicate that tinnitus-related distress decreased as a function of receiving evidence-based therapy for PTSD. Future clinical trials should increase sample sizes and compare effects to control conditions.
Null Controllability of the Parabolic Spherical Grushin Equation
Authors: Tamekue Cyprien
Published: August 2022

We investigate the null controllability property of the parabolic equation associated with the Grushin operator defined by the canonical almost-Riemannian structure on the 2-dimensional sphere 𝕊2. This is the natural generalization of the Grushin operator 𝒢 = ∂x2 + x2∂y2 on ℝ2 to this curved setting and presents a degeneracy at the equator of 𝕊2. We prove that the null controllability is verified in large time when the control acts as a source term distributed on a subset ω̅ = {(x1, x2, x3) ∈ 𝕊2 | α < | x3 | < β} for some 0 ≤ α < β ≤ 1. More precisely, we show the existence of a positive time T* > 0 such that the system is null controllable from ω̅ in any time T ≥ T*, and that the minimal time of control from ω̅ satisfies Tmin ≥ log(1/√(1 - α2)) . Here, the lower bound corresponds to the Agmon distance of ω̅ from the equator. These results are obtained by proving a suitable Carleman estimate using unitary transformations and Hardy-Poincaré type inequalities to show the positive null-controllability result. The negative statement is proved by exploiting an appropriate family of spherical harmonics, concentrating at the equator, to falsify the uniform observability inequality.

Ionospheric irregularities impair Global Navigation Satellite System (GNSS) signals and, in turn, affect the performance of GNSS positioning. Such effects are especially evident at low and high latitudes, which are currently gaining the attention of research and industry sectors. This study evaluates the impact of ionospheric irregularities on GNSS positioning in Greenland. We assess the performance of positioning methods that meet the demands of a wide range of users. In particular, we address the needs of the users of mass-market single-frequency receivers and those who require a solution of high precision provided by geodetic dual-frequency receivers. We take advantage of the datasets collected during three ionospheric storms: the St. Patrick’s Day storm of March 17, 2015, the storm on June 22, 2015, and another on August 25–26, 2018. We discover a significant impact of the ionospheric disturbances on the ambiguity resolution performance and the accuracy of the float solution in Real Time Kinematics (RTK) positioning. Next, assessing the single-frequency ionosphere-free Precise Point Positioning (PPP), we demonstrate that the model is generally unaffected by ionospheric disturbances. Hence, the model is predestined for the application by the users of single-frequency receivers in the areas of frequent ionospheric disturbances. Finally, based on the observation analyses, we reveal that phase signals on the L2 frequency band are more prone to cycle slips induced by ionospheric irregularities than those transmitted on the L1. Such signal properties explain a noticeable decline in the dual-frequency RTK performance during the ionospherically disturbed period and merely no effect for the single-frequency ionosphere-free PPP model.

Long-Delayed Manifestation of COVID-19 Coagulopathy Presenting with Severe Cerebral Venous Thrombosis Causes Massive Brain Hemorrhage
Authors: Tjahjadi Mardjono , Caropeboka Sinatrya , Permana Christian , Susanto Krisandi , Susanto Eka
Published: August 2022

COVID-19 infection causes coagulopathy, which may lead to cerebral venous thrombotic (CVT) event. It usually occurs in patients with higher severity level of infection and manifests mostly within a month after the infection. However, in rare cases, the CVT may happen long after the infection and unrelated to the degree of the infection severity. We present the case of a previously healthy 62-year-old male patient with very mild COVID-19 symptoms that resolved in 3 weeks of home isolation treatment. Immediately after the infection, he developed hypercoagulability and was treated routinely with a novel oral anti-coagulant drug. Four months after the infection, he developed a worsening headache which, in several days, deteriorated to cause reduction in his consciousness level. Imaging showed a right temporoparietooccipital massive brain hemorrhage with right transverse and sigmoid sinus thrombosis. Emergency decompressive craniectomy was performed and the patient recovery was excellent. In patients with a hypercoagulable state after COVID-19 infection, the possibility of CVT event should be observed. It may not be related to the severity of the infection, and it may happen long after the infection.
Numerical characterization of optical properties of tapered plasmonic structure on a cantilever pyramidal tip for plasmon nanofocusing
Authors: Yadav Ravi , Umakoshi Takayuki , Verma Prabhat
Published: August 2022

The plasmon nanofocusing process has been widely implemented in near-field scanning optical microscopy (NSOM) recently because it allows generating a background-free nanolight source at the apex of a metallic tip, enabling high contrast imaging at the nanoscale. In plasmon nanofocusing-assisted NSOM, the metallic tip properties play a vital role in generating an intense and well-confined nanolight source by controlling the plasmons’ behavior. This is why various tip designs have been developed so far. Recently, our group has also developed a metallic tapered tip, composed of a dielectric pyramidal base and a thin metallic layer coated on one side of the pyramid, using a novel fabrication method that allows tuning the optical properties of a tip depending on the requirement. Although our metallic tip has a unique advantage of tuning its optical properties, it has not yet been well studied. In this work, we present a thorough study of the optical properties of our metallic tip that depends on its parameters, such as the dielectric material, metal thickness, and cone angle, using finite-difference time-domain simulations. This particular study will allow us to understand controlling the tip’s optical properties and expand it for a wide range of applications.
Interfacial mixing effect in a promising skyrmionic material: Ferrimagnetic Mn4N
Authors: Ma Chung T. , Zhou Wei , Kirby Brian J. , Poon S. Joseph
Published: August 2022

Interfacial mixing of elements is a well-known phenomenon found in thin film deposition. For thin-film magnetic heterostructures, interfacial compositional inhomogeneities can have drastic effects on the resulting functionalities. As such, care must be taken to characterize the compositional and magnetic properties of thin films intended for device use. Recently, ferrimagnetic Mn4N thin films have drawn considerable interest due to exhibiting perpendicular magnetic anisotropy, high domain-wall mobility, and good thermal stability. In this study, we employed x-ray photoelectron spectroscopy (XPS) and polarized neutron reflectometry (PNR) measurements to investigate the interfaces of an epitaxially grown MgO/Mn4N/Pt trilayer deposited at 450 °C. XPS revealed the thickness of elemental mixing regions of near 5 nm at both interfaces. Using PNR, we found that these interfaces exhibit essentially zero net magnetization at room temperature. Despite the high-temperature deposition at 450 °C, the thickness of mixing regions is comparable to those observed in magnetic films deposited at room temperature. Micromagnetic simulations show that this interfacial mixing should not deter the robust formation of small skyrmions, consistent with a recent experiment. The results obtained are encouraging in terms of the potential of integrating thermally stable Mn4N into future spintronic devices.
Numeral form selection and accommodation in Gulf Pidgin Arabic
Authors: Alshammari Wafi Fhaid
Published: August 2022

This study deals with the creation of cardinal numerals and accommodation in Gulf Pidgin Arabic (GPA) as it is spoken among foreign workers (FWs) and native Saudi Arabic speakers (Ss) in Saudi Arabia. Under theFeature Pool Hypothesis(Mufwene, 2001) and theMutual Accommodation Theory(Thomason & Kaufman, 1988), this study looks at the features of gender and number agreement, and word order of the cardinal numeral and the noun. Data comes from interviews between Ss and FWs in GPA, and photo elicitation interviews used with Ss to identify how cardinals are used in Najdi Arabic. Through the lens of the Feature Pool Model, I offer a brief account of how cardinal numeral forms are selected in GPA. In particular, I examine how well cognitive factors account for the development and restructuring processes of the cardinal numeral system in GPA by taking into account factors such as frequency, perceptual salience (detectability), and pattern regularization, as well as the Foreigner-Talk register and accommodation. The results reveal strong tendencies of accommodation and conventionalization in numeral form selection.
Controlled assembly of gold nanoparticles in resonant gold nanoapertures for SERS applications
Authors: Pillanagrovi Jayakumar , Dutta-Gupta Shourya
Published: August 2022

The controlled assembly of plasmonic nanoparticles is vital for realizing low-cost, high efficiency plasmonic substrates with tunable resonances. Here, we present a strategy to assemble gold nanoparticles (AuNPs) in resonant gold nanoapertures (NAs) to enable coupling-mediated near-field enhancement. The NAs templates are fabricated using shadow sphere lithography on polyelectrolyte (PE) coated substrates. Subsequently, AuNPs are assembled in the resonant NA templates via a simple immersion step. The PE layer, AuNP concentration, NaCl concentration, incubation time, and template thickness are used to control the particle number per aperture and the interparticle distance of the AuNP assemblies. The fabricated AuNP-NA substrates are evaluated for their SERS potential using 4-Mercaptobenzoic acid (MBA) as a Raman reporter molecule. The SERS intensity of the AuNP-NA templates can be enhanced by ten times by controlling the AuNP and NA template parameters as compared to the bare NA templates. Numerical simulations show that the coupling between the various plasmonic modes is crucial for this SERS enhancement. The proposed strategy can be used to fabricate hybrid AuNP-NA based SERS substrates with improved sensitivity.

Published: August 2022

Strong nonlinear interactions between single photons have important applications in optical quantum information processing. Demonstrations of these interactions in cold atomic ensembles have largely been limited to exploiting slow light generated using electromagnetically induced transparency (EIT). However, these EIT implementations have limited achievable phase shifts due to spontaneous emission. Here, we demonstrate and characterize a scheme free from these limitations using gradient echo memory with inferred single photon phase shifts of 0.07 ± 0.02 μrad. Excellent agreement with theoretical modelling was observed. Degradation of memory efficiency was observed for large phase shifts but strategies to overcome that are presented.

The structural, electronic, optical, elastic, and thermoelectric (TE) characteristics of Na2YCuX6 (X = Br, Cl) halide double-perovskites (HDPs) were investigated by using first principle approach within WIEN2K code. Perdew, Burke and Ernzerhof generalized-gradient approximation (PBEsol-GGA) with modified Becke-Johnson (mBJ) potential were used in the current investigations. Enthalpy of formation energies (Ef) determined for Na2YCuBr6 and Na2YCuCl6 were −2.29 and −1.955 eV, correspondingly which verify the stability of both compounds. Na2YCuBr6 is discovered to be semiconducting with indirect bandgap (Eg) of 2.492 and Na2YCuCl6 has direct Eg of 2.571 eV. Absorption coefficient shows largest values at 5.74 and 6.92 eV for Na2YCuBr6 and Na2YCuCl6, correspondingly, which lie in UV range. Pugh’s ratio (B/G) values were calculated as 2.00 and 4.62 for Na2YCuCl6 and Na2YCuBr6, correspondingly which ensure the ionic bond and ductile characteristics of the compounds. From the TE calculations, ZT shows maximum values of 0.74 and 0.73 for Na2YCuBr6 and Na2YCuCl6, respectively. Results showed that investigated materials are efficient candidates for optoelectronic and TE appliances.
Observational Hubble parameter data constraints on the interactive model of

gravity with particle creation
Authors: Ganjizadeh S. , Amani Alireza , Ramzanpour M. A.
Published: August 2022

In this study, we consider an open system from the thermodynamic perspective for an adiabatic FRW universe model in which particle creation occurs within the system. In this case, the modified continuity equation is obtained, and then, we make it correspond to the continuity equation of

gravity. Therefore, we take

gravity with a viscous fluid in the flat-FRW metric, where T is the torsion scalar. We assume the contents of the universe to be dark matter and dark energy and consider an interaction term between them. An interesting point of this study is that we make the modified continuity equation resulting from particle creation equivalent to the matter continuity equation resulting from

gravity. The result of this evaluation establishes a relationship between the number of particles and scale factor. In what follows, we write the corresponding cosmological parameters in terms of the number of particles and also reconstruct the number of particles in terms of the redshift parameter. We then parameterize the Hubble parameter derived from power-law cosmology with 51 data points from the Hubble observational parameter data. Next, we plot the corresponding cosmological parameters for dark energy in terms of the redshift to investigate the accelerated expansion of the universe. In addition, by using the sound speed parameter, we discuss the stability and instability analyses of the present model in different eras of the universe. Finally, we plot the density parameter values for dark energy and dark matter in terms of the redshift parameter.

Published: August 2022

Metallic nanoparticles find tremendous applications in every field. The surface morphology of these metallic nanoparticles drives their properties and is usually regulated by their mode of synthesis. Apart from chemical and physical methods available for producing metallic nanoparticles, ‘plant-mediated synthesis’ is considered advantageous mainly because of its eco-friendly nature and cost-effectiveness. Plant-based materials have been successfully incorporated in food, pharmaceuticals as well as in tissue engineering applications. The secondary metabolites in plants are of prime importance as they play a major role as reducing agents. Therefore, numerous plants bearing diversified phytochemical profiles have been explored for the synthesis of metallic nanoparticles. The current review attempts to encompass available information about the synthesis and application of different metallic nanoparticles employing herbal extracts. Further, critical insights about the properties of metallic nanoparticles, their morphology, and anticipated applications (e.g. antimicrobial, anticancer, anti-diabetic, photo-catalytic, etc) with a futuristic approach are discussed.
Smooth weight structures and birationality filtrations on motivic categories
Authors: Bondarko M. , Kumallagov D.
Published: August 2022

In various triangulated motivic categories, a vast family of aisles (these are certain classes of objects) is introduced. These aisles are defined in terms of the corresponding “motives” (or motivic spectra) of smooth varieties; it is proved that they are expressed in terms of the corresponding homotopytt-structures. The aisles in question are described in terms of stalks at function fields, and it is shown that they widely generalize the ones corresponding to slice filtrations. Further, the filtrations on the “homotopy hearts”Ht_homeff{\underline {Ht}}_{\mathrm {hom}}^{\mathrm {eff}}of the corresponding effective subcategories that are induced by these aisles can be described in terms of (Nisnevich) sheaf cohomology as well as in terms of the Voevodsky contractions−−1-_{-1}. Respectively, the condition for an object ofHt_homeff{\underline {Ht}}_{\mathrm {hom}}^{\mathrm {eff}}to be weakly birational (i.e., for its(n+1)(n+1)st contraction to be trivial, or equivalently, its Nisnevich cohomology to vanish in degrees strictly greater thannnfor somen≥0n\ge 0) are expressed in terms of these aisles; this statement generalizes well-known results of Kahn and Sujatha. Next, these classes give rise to weight structureswSmoothsw_{\mathrm {Smooth}}^{s}(where thes=(sj)s=(s_{j})are nondecreasing sequences parametrizing our aisles) that vastly generalize the Chow weight structureswChoww_{\operatorname {Chow}}defined earlier. By using general abstract nonsense, the correspondingadjacenttt-structurestSmoothst_{\mathrm {Smooth}}^{s}are constructed and it is proved that they give the birationality filtrations onHt_homeff{\underline {Ht}}^{\mathrm {eff}}_{\mathrm {hom}}.

Moreover, some of these weight structures induce weight structures on the correspondingnn-birational motivic categories (these are the localizations by the levels of the slice filtrations). The results also yield some new unramified cohomology calculations.

A role for Wnt/Ror2 signaling in the regulation of tumor cell-extracellular matrix interactions during cancer invasion is uncovered. The noncanonical Wnt receptor Ror2 regulates integrin-matrix adhesions, with important implications for tumor cell mechanotransduction and ECM architecture in cancer metastasis.
Ultrastructure of COPII vesicle formation in yeast characterized by correlative light and electron microscopy
Authors: Melero Alejandro , Boulanger Jerome , Kukulski Wanda , Miller Elizabeth A.
Published: August 2022

CLEM in yeast cells was used to characterize the formation of COPII vesicles. Their analysis suggests that the COPII inner coat defines the radius of curvature, whereas the outer coat facilitates vesicle fission. Coat organization and membrane biophysical properties determine the ultrastructure of vesicles and protein transport efficiency.
Does the Critical Scrutiny of Drill Constitute an Epistemic Injustice?
Authors: Omar Jalloh Tareeq
Published: August 2022

In this paper, I look to draw novel connections between critiques of drill and epistemic injustice by addressing the question of whether the critical scrutiny of drill constitutes an epistemic injustice. I argue that these critiques constitute two types of epistemic injustice: testimonial injustice and contributory injustice. We see testimonial injustice in how courts and police do not give credibility to drill artists’ testimonies about the storylike nature of their songs, and these credibility deficits are based in racist stereotypes about black criminality and believability. We see contributory injustice in how courts and police, through wilful ignorance, see drill music as violent and criminal rather than expressive and fictional – as drill artists do – which thwarts drill artists’ ability to contribute to shared knowledge.
Monument Gallery
Authors: Getachew Adom , Kebede Naomi
Published: August 2022

These capsule case studies of contestations over monuments illuminate the global iconoclasm that has marked our recent past and attend to the many registers and settings in which publics are challenging seemingly settled historical narratives. They take readers to monumental public campaigns in South Africa, the United Kingdom, Mexico, Belgium, and the United States. Each capsule includes an image, a short description and suggestions for further reading. We hope that these might prove useful as teaching texts, and we have where possible included multimedia sources.

Published: August 2022

Objectives

We aimed to better understand the histologic changes in vaginectomy specimens in transgender and gender-diverse (TGD) individuals after prolonged androgen administration.

Methods

After obtaining institutional review board approval, we reviewed clinical records for all TGD individuals who underwent vaginal tissue resection at our institution between January 2002 and July 2020.

Results

Ten transgender males who underwent vaginectomy for gender affirmation were identified. All patients had been assigned female gender at birth, and the median age at surgery was 41 years (range, 22-74 years). All 10 patients had received androgen for 2 to 10 years preoperatively. The corresponding pathology specimens were examined grossly and microscopically, including with immunohistochemical stains for NKX3.1, prostate-specific antigen (PSA), p501s, and androgen receptor (AR). No gross lesions were identified. Microscopically, prostate-like glands (8/10), urothelial metaplasia (4/10), and vaginal atrophy (8/10) were identified. Seven cases with prostate-like glands showed positive staining with PSA, NKX3.1, p501s, and AR in both squamous and glandular components.

Conclusions

Recognition of these androgen-related changes enables pathologist to avoid the overdiagnosis of dysplasia. Long-term follow-up is needed to thoroughly understand any potential future implications of these androgen-related changes.
Evaluation of a Newly Implemented Critical Thromboelastography (TEG) Value Callback System
Authors: Yang Shanna , McRae Hannah L , Terry Treyc , Cahill Christine M , Refaai Majed A
Published: August 2022

Objectives

Thromboelastography (TEG) measures whole blood coagulation kinetics in real time and is useful in guiding blood product transfusion. At our institution, providers have immediate remote access to TEG results. However, some critical values are occasionally missed. Our patient blood management program implemented a critical TEG value callback system to improve patient management and blood product utilization.

Methods

This retrospective, observational study assessed the data of trauma and critical care patients preimplementation (n = 20) and postimplementation (n = 100) of the callback system. Provider responses to callbacks and changes in TEG parameters after subsequent testing were compared between the two groups.

Results

In response to callbacks, 42% provided appropriate management and 42% ordered a repeat TEG vs 28% and 33% in the historical group (P < .0001 and P = .0002, respectively). Following callback, 90% of the TEG parameters in the study group showed an improvement vs 57% in the control group (P = .011).

Conclusions

The increase in appropriate management and the improvement in TEG parameters upon repeat testing in the study group compared to the control group demonstrate the efficacy of the TEG callback system. Further studies are needed to evaluate the callback system effect on patient outcome.
Triparental ageing in a laboratory population of an insect with maternal care

Published: August 2022

Parental age at reproduction influences offspring size and survival by affecting prenatal and postnatal conditions in a wide variety of species, including humans. However, most investigations into this manifestation of ageing focus upon maternal age effects; the effects of paternal age and interactions between maternal and paternal age are often neglected. Furthermore, even when maternal age effects are studied, pre- and post-natal effects are often confounded. Using a cross-fostered experimental design, we investigated the joint effects of pre-natal paternal and maternal and post-natal maternal ages on five traits related to offspring outcomes in a laboratory population of a species of burying beetle, Nicrophorus vespilloides. We found a significant positive effect of the age of the egg producer on larval survival to dispersal. We found more statistical evidence for interaction effects, which acted on larval survival and egg length. Both interaction effects were negative and involved the age of the egg-producer, indicating that age-related pre-natal maternal improvements were mitigated by increasing age in fathers and foster mothers. These results agree with an early study that found little evidence for maternal senescence, but it emphasizes that parental age interactions may be an important contributor to ageing patterns. We discuss how the peculiar life history of this species may promote selection to resist the evolution of parental age effects, and how this might have influenced our ability to detect senescence.
Pathway integration and annotation: building a puzzle with non-matching pieces and no reference picture
Authors: Agapito Giuseppe , Pastrello Chiara , Niu Yun , Jurisica Igor
Published: August 2022

Biological pathways are a broadly used formalism for representing and interpreting the cascade of biochemical reactions underlying cellular and biological mechanisms. Pathway representation provides an ontological link among biomolecules such as RNA, DNA, small molecules, proteins, protein complexes, hormones and genes. Frequently, pathway annotations are used to identify mechanisms linked to genes within affected biological contexts. This important role and the simplicity and elegance in representing complex interactions led to an explosion of pathway representations and databases. Unfortunately, the lack of overlap across databases results in inconsistent enrichment analysis results, unless databases are integrated. However, due to absence of consensus, guidelines or gold standards in pathway definition and representation, integration of data across pathway databases is not straightforward. Despite multiple attempts to provide consolidated pathways, highly related, redundant, poorly overlapping or ambiguous pathways continue to render pathways analysis inconsistent and hard to interpret. Ontology-based integration will promote unbiased, comprehensive yet streamlined analysis of experiments, and will reduce the number of enriched pathways when performing pathway enrichment analysis. Moreover, appropriate and consolidated pathways provide better training data for pathway prediction algorithms. In this manuscript, we describe the current methods for pathway consolidation, their strengths and pitfalls, and highlight directions for future improvements to this research area.
