The School-Based Speech-Language Pathologist and Students With Concussion: An Examination of Evolving Knowledge and Confidence
Authors: O'Brien Katy H. , Lundine Jennifer P. , Pei Yalian , Kemp Amy M.
Published: July 2022

Purpose:

This study examines school-based speech-language pathologists' (SLPs’) experience, knowledge, and confidence in supporting students as they return to the classroom following concussion, with a particular focus on knowledge of new management guidelines over the last decade.

Method:

Participants were 74 school-based SLPs who completed an electronic survey about their knowledge and experiences serving students with concussion. We examined participants' accuracy and confidence across knowledge questions using Kruskal–Wallis tests. We also conducted linear regression to explore the relationships between training, work experiences, knowledge, and confidence.

Results:

Nearly half of participants who are currently working with students with concussion reported having no clinical or training experiences related to concussion. Participants who had more concussion-related training or working experiences reported higher confidence. Participants were confident about general concussion knowledge but less confident about providing assessment and supporting students with concussion as they returned to school. Participants had the lowest confidence and accuracy for the most recent guidelines around rest and activity, as well as the differential impact of concussion on children as compared to adults.

Conclusions:

Many school-based SLPs have limited training around concussion management and are often not specifically consulted to work with students following concussion. Despite this, SLPs have good awareness of their knowledge about concussion, but show gaps in knowledge surrounding more recent evidence-based guidelines. Additional investigation is needed to determine better ways to move research into clinical practice and to increase the involvement of SLPs in school-based concussion teams.

Infinite multidimensional scaling for metric measure spaces
Authors: Kroshnin Alexey , Stepanov Eugene , Trevisan Dario
Published: July 2022

For a given metric measure space (X, d,μ) we consider finite samples of points, calculate the matrix of distances between them and then reconstruct the points in some finite-dimensional space using the multidimensional scaling (MDS) algorithm with this distance matrix as an input. We show that this procedure gives a natural limit as the number of points in the samples grows to infinity and the density of points approaches the measure μ. This limit can be viewed as “infinite MDS” embedding of the original space, now not anymore into a finite-dimensional space but rather into an infinitedimensional Hilbert space. We further show that this embedding is stable with respect to the natural convergence of metric measure spaces. However, contrary to what is usually believed in applications, we show that in many cases it does not preserve distances, nor is even bi-Lipschitz, but may provide snowflake (Assouad-type) embeddings of the original space to a Hilbert space (this is, for instance, the case of a sphere and a flat torus equipped with their geodesic distances).
Selection of financing strategies and business modes for a capital-constrained manufacturer
Authors: Gao Yi , Fang Lei
Published: July 2022

E-commerce platforms adopt both reseller and agency business modes to achieve better performance, and also provide financing services for qualified manufacturers to alleviate their financial difficulties. This paper analyzes financing strategy (bank financing or platform financing) and business mode selection (reseller mode, agency mode or both of them) for a capital-constrained manufacturer. We find that no matter which business mode is adopted, the platform always provides lower interest rates than bank, which in turn makes retail prices lower. Meanwhile, the manufacturer and the platform can become more profitable under platform financing. In addition, compared with the manufacturer adopting bank financing, the manufacturer has different business mode preferences when adopting platform financing. We put forward business mode recommendations for the manufacturer under different financing strategies.
S2k-Leitlinie Hüftdysplasie Teil Säugling

Published: July 2022

Hüftreifungsstörungen stellen in Mitteleuropa die häufigste muskuloskelettale Erkrankung im Neugeborenalter dar. Der Begriff Hüftreifungsstörung umfasst dabei sowohl dysplastische als auch
luxierte Gelenke. Bei einem dysplastischen Gelenk kommt es aufgrund von Scherkräften zu einer Wachstumsstörung im Bereich der Hüftpfanne. Bei einem Fortbestehen der Wachstumsstörung im Bereich
der Hüftpfanne verdrängt der Hüftkopf den knorpelig präformierten Anteil der Gelenkpfanne erst nach kranial und luxiert schlussendlich nach dorsal in die Fossa glutealis. Der Hüftkopf verliert
bei der Luxation zunehmend den Kontakt zur Pfanne. Wir sprechen dementsprechend heute von einer Developmental Dislocation of the Hip und nicht mehr von einer Congenital Dislocation of the Hip.
Die verschiedenen Stadien der Hüftreifungsstörung lassen sich anhand einer Ultraschalluntersuchung des Säuglingshüftgelenks nach Graf ab dem 1. Lebenstag exakt klassifizieren. Die
Hüftultraschalluntersuchung nach Graf ist daher seit 1996 in Deutschland fester Bestandstandteil der Kinderrichtlinie. Alle Neugeborenen müssen im Rahmen der 3. Vorsorgeuntersuchung U3
idealerweise im Alter von 4–5 (maximal 8) Wochen einer Hüftultraschalluntersuchung nach Graf unterzogen werden. Bei Neugeborenen mit anamnestischen oder klinischen Risikofaktoren muss darüber
hinaus bereits bei der 2. Vorsorgeuntersuchung U2 in der 1. Lebenswoche neben einer klinischen Untersuchung der Hüftgelenke auch eine Ultraschalluntersuchung erfolgen. Basierend auf dieser
Frühestdiagnostik sollte bei pathologischen Befunden möglichst innerhalb 1 Woche eine dem Befund entsprechende Therapie eingeleitet werden. Luxierte Gelenke werden reponiert. Nach
Wiederherstellen des Kontakts von Hüftkopf und Pfanne ist es zwingend erforderlich, dass der Kopf sicher in der Pfanne gehalten wird. Nach dieser Phase der Retention schließt sich bei luxierten
Gelenken die für dysplastische Gelenke als Therapie ausreichende Nachreifungsphase an. Um eine Hüftkopfnekrose als Frühkomplikation oder eine erneute Hüftreifungsstörung im weiteren Wachstum zu
vermeiden, wird der Hüftkopf sowohl während der Retentionsphase als auch während der Nachreifungsphase tief in die Pfanne eingestellt. Dies gelingt bei Sicherstellung einer Hüftflexion von
100–110° bei gleichzeitiger Hüftabduktion von 50° bis maximal 60°.

Authors: Ye Shuming , Sun Jian , Jing Juehua
Published: July 2022

Background The purpose of this study was to evaluate the clinical outcomes of thoracic and lumbar spinal tuberculosis treated with isolated posterior instrumentation without radical
debridement.

Methods This study retrospectively analyzed 73 patients with thoracic and lumbar spinal tuberculosis who were treated using isolated posterior instrumentation without radical
debridement in our hospital between January 2012 to December 2019. The patient group was composed of 42 men and 31 women with a mean age of 67.3 ± 8.6 years. The tuberculosis spine
instability score (TSIS) was used to evaluate spine stability. All patients received chemotherapy for 18 months after surgery. The time of surgery, blood loss, visual analogue score (VAS),
kyphosis angle, Oswestry disability index (ODI), erythrocyte sedimentation rate (ESR), Frankel grading, SF-36 scores, and local recurrence and complications were analyzed to evaluate the
efficacy of isolated posterior instrumentation surgery in the treatment of thoracic and lumbar spinal tuberculosis.

Results All patients were followed up for 12 to 24 months (mean 14 ± 3.2 months). The mean surgical time was 1.2 ± 1.4 h (range, 1.2–1.6 h), and mean blood loss was 107 ± 18 mL. The
postoperative symptoms were obviously relieved. The VAS, kyphosis angle, DI, and ESR decreased, respectively, from 8.24 ± 1.32, 19.82 ± 3.42, 46.25 ± 3.62, and 49.64 ± 17.61 to 1.12 ± 0.21,
7.14 ± 0.81, 20.17 ± 5.11, and 0.35 ± 1.13 at final follow-up. In comparison to preoperative values, SF-36 scores were significantly improved at final follow-up and the differences were
statistically significant (p < 0.05). All patients achieved neurological recovery at the final follow-up. There were no recurrences or complications in any of the patients.

Conclusion Isolated posterior instrumentation without radical debridement is a suitable minor surgical trauma that offers a remarkable advantage of effective pain relief, improvement
in neurological function and performance status, and no local recurrence for selected patients with thoracic and lumbar spinal tuberculosis.
Applying the Hearing Aid Fitting Standard to Selection for Adults
Authors: Picou Erin M. , Roberts Richard A. , Angley Gina , Ricketts Todd A.
Published: July 2022

The recent hearing aid fitting standard for adults outlines the minimum practice for audiologists fitting adult patients with hearing loss. This article focuses on three items of the standard (5, 6, and 7), which focus on the selection of unilateral/bilateral hearing aids, hearing aid style, and coupling, in addition to feature selection. The standard emphasizes that decisions around these three aspects should be recommended for a patient in an individualized manner, based on their needs assessment. For these decisions, the needs assessment might include measures of speech-in-noise ability, social network size, patient preference, and a trial period. Additional elements could include assessments of manual dexterity, binaural interference, and attitude toward hearing aids. However, there are a multitude of ways to practice clinically and still meet the items outlined in the standard. As long as the selection decisions consider individualized patient factors and are capable of meeting validated prescriptive targets, a clinician would be meeting the adult hearing aid fitting minimum standard guidance. In addition, despite the large number of past studies supporting these standards, additional, high-quality research including randomized, controlled, clinical trials are still needed to further support appropriate minimum standard recommendations.

Published: July 2022

The Audiology Practice Standards Organization (APSO) has published its second audiology standard. This second standard is focused on adult hearing aid fittings. These standards put forward information about verification that should be completed on hearing aids before, during, and after a fitting. Validation following the verification of the hearing aids to ensure patient satisfaction with the devices is also included in the standards. The goal of this article is to provide clinicians with the guidelines related to hearing aid verification and validation while also providing information about how to put these standards into clinical practice.

Published: July 2022

Acute myeloid leukemia (AML) are a diverse group of hematological malignancies, each with a distinct clinical, morphological, immunophenotypic, and molecular profile. The World Health Organization (WHO) classifies AML into various subtypes based on recurrent genetic abnormalities, each of which has clinico-pathological and prognostic significance. Inversion(16)(p13q22) or t(16;16)(p13q22) is a balanced structural chromosomal abnormality associated with complete remission and a favorable response to treatment. Trisomy 9 is a numerical chromosomal abnormality with an intermediate risk and is often seen in association with other cytogenetic abnormalities. We describe a case of a 36-year-old female patient who was diagnosed as AML-M4 on peripheral smear and bone marrow evaluation. Cytogenetic studies revealed concurrent presence of inv(16) and trisomy 9. To the best of our knowledge, this is the first case in published literature with simultaneous presence of inv(16)(p13q22) and trisomy 9 in de novo AML.
Impact of Pneumatic Transport System on Preanalytical Phase Affecting Clinical Biochemistry Results
Authors: Kumari Sweta , Kumar Santosh , Bharti Neha , Shekhar Ravi
Published: July 2022

Introduction PTS (pneumatic transport system) is extensively being used in modern hospitals for rapid transportation of blood samples and other specimens. However, it has a potential impact on blood components, which should be investigated and nullified accordingly. This study was part of a correction program aimed at reducing hemolysis. It was done by comparing paired samples transported manually and by PTS.

Materials and Methods This study was initiated to monitor the impact of PTS on hemolysis of clinical biochemistry blood samples. It was performed in two phases—before and after the corrective action taken. Phase I: done after PTS installation but before the corrective action was taken. Duplicate samples from 100 healthy individuals were collected, one set transported by PTS and the other by human carriers. Both sets were assessed for 25 biochemistry analytes, hemolysis index (HI), and acceleration profiles using a data logger. Corrective measures were then taken, followed by phase II of the study. In phase II, the sample size and study design remained the same as phase I. All the test results of PTS and hand-carried samples were statistically analyzed for any significant difference.

Result In phase I, all the hemolysis-manifesting parameters, LDH (lactate dehydrogenase), potassium, AST (aspartate transaminase), and phosphorus, were raised in PTS samples as compared with the manual samples. Their differences were significant as the p-values were 0.001, 0.000, 0.025, and 0.047, respectively. The differences for LDH and potassium were clinically significant as well. HI (9%) and peak acceleration (15.7 g) were high in PTS samples.

In phase II, no statistically significant difference between paired samples was found for all biochemistry parameters except for a few which were clinically nonsignificant. For PTS samples, HI was 2.5% and the peak acceleration was 11.2 g, whereas for manual samples, HI was 2%.

Conclusion Evidence of hemolysis was found in PTS samples as compared with handheld samples, which was resolved after several corrective actions were taken. Thereafter, PTS became reliable for sample delivery in a routine biochemistry laboratory. Hence, each hospital should scrutinize their PTS for its effects on sample integrity to get rid of PTS-induced preanalytical errors.
Posttreatment Persistence of Monoclonal Protein on Immunofixation Electrophoresis but Absence on Serum Protein Electrophoresis in a Case of Solitary Bone Plasmacytoma
Authors: Kumar Visesh , Rani Priti , Rai Neha , Kumar Subhash , Mahto Mala
Published: July 2022

Laboratory investigations for any suspected case of solitary plasmacytoma of bone include routine biochemical and hematological investigations along with β2-microglobulin, electrophoresis of serum protein and/or 24-hour urine protein, serum protein immunofixation (IFE), and nephelometric quantification of total immunoglobulin isotype and serum free light chain levels. Bone marrow aspirate and trephine biopsy are mandatory to confirm the absence of clonal plasma cells (for solitary plasmacytoma) or the presence of less than 10% clonal cells (solitary plasmacytoma with minimal bone marrow involvement). Imaging studies such as X-ray, computed tomography (CT), magnetic resonance imaging, and positron emission tomography/CT should be used to complement laboratory tests in diagnosis, staging, and defining the local extent of the plasmacytoma. However, guidelines regarding choice of technique for the detection of M band when monitoring a follow-up case of operated plasmacytoma are still not clear. Through this case study, we try to highlight the role of IFE in a follow-up case of operated solitary plasmacytoma of the bone.

Published: July 2022

With the increasing exhaustion of the traditional fossil energy and ongoing enhanced awareness of environment protection, research works on electrochemical energy storage (EES) devices have been indispensable. Now, a significant amount of works (design and fabrication of electrode materials, electrolytes, separators, etc.) devoted to improving energy and power density, safety, and service life of EES devices are under way to meet the demand for various applications. However, besides the intrinsic factors, the service environments of EES devices, such as ultra-low or ultra-high temperatures, external magnetic field, external stress, severe radiation, and other factors (electric field, light, etc.) in practical applications, will greatly affect their performance, particularly when applied to aerospace, submarine, polar scientific research, and so on. Yet, research works on EES devices in the extreme environments are limited, and enormous efforts are highly needed to overcome the existing fundamental and technological barriers. Herein, we mainly focus on the EES devices under particular service environments. On the one hand, we present a comprehensive analysis into the inherent effects of external service environments on electrochemical behaviors of EES devices and underlying effect mechanisms. On the other hand, a summary of recent progress in EES devices under particular service environments, including systematic experiments and simulations, is provided along with the well-established strategies/methodologies toward enhanced electrochemical properties under these external environments. Finally, current challenges and future perspectives are proposed. The review is of enormous significance for the development of advanced EES devices especially under particular service environments.
How important is fire-induced disturbance in the maintenance of a threatened perennial forb,
Authors: Osazuwa Omofomwan Kingsley , Dwyer John Matthew , Fensham Roderick John
Published: July 2022

Context Many grassland forb populations have greatly diminished because their habitat coincides with prime agricultural land and remnants lack appropriate disturbance regimes. Aim The aim of the current study is to examine the survivorship, vegetative recruitment, biomass and sexual reproduction of S. papaverifolium in response to burning in one of a few natural surviving populations in Queensland. Methods We monitored the survivorship, vegetative recruitment, and reproduction of a rare native forb, Solanum papaverifolium, within a randomised replicated experiment by using 14 circular plots measuring 12.56 m2 (2 m radius). Key results Plant survival rate after 5 months was greater in the burnt plots (56%) than the unburnt plots (44%). Vegetative recruitment from suckers in the burnt plots was almost twice that in the unburnt plots. The probability of flowering was also enhanced by burning. Fruit set in new recruits was higher in the burnt plots (20%) than in the unburnt plots (5%). Whereas fruiting did not occur in unburnt plots for surviving plants that flowered, only 1% fruited in the burnt plots. Seedling production was not observed. Conclusion Previous studies have demonstrated that the subtropical grassland flora in the study region is unaffected by burning, whereas the present study suggests that some grassland species respond positively to burning. Implications Although fire increased flowering in this species, suggesting that fire may be a useful tool to stimulate sexual reproduction, ongoing research is required to understand the precise factors that promote flowering after burning and the barriers to seedling reproduction.
Coastal wetland rehabilitation first-pass prioritisation for blue carbon and associated co-benefits

Published: July 2022

Context The Australian Government has developed a methodology for payment for carbon services provided by blue carbon ecosystems that focuses on avoided emissions and carbon additionality resulting from tidal restoration of coastal wetlands. Aims This study is a first-pass prioritisation for tidal restoration of coastal wetlands in New South Wales (NSW). Methods A pixel-based approach was applied using readily available datasets, with particular focus on watersheds above in-stream tidal barriers. Key results Many sites were identified, to investigate in detail, opportunities to restore tidal flows to coastal wetlands. More were associated with the broad coastal floodplains of northern NSW than narrower floodplains of southern NSW. Conclusions Information is needed about the location, ownership, land tenure, structure, condition and height of in-stream and over-land flow barriers, particularly in the context of rising sea levels. Decisions about managing in-stream drainage and flood mitigation infrastructure should be made cognisant of opportunities to increase blue carbon, and provide associated co-benefits, including mitigating other deleterious impacts from coastal wetland drainage. Implications Decision support tools for evaluating economic and environmental costs and benefits of tidal barriers will assist decision-makers assessing future proposals to repair or remove aging barriers, or create new tidal barriers.

Published: July 2022

Vatica venulosa is one of the Dipterocarpaceae species that is threatened with extinction. Distributed in Peninsular Malaysia, Sumatra and Borneo, the tree is classified as Critically Endangered by IUCN Red List (International Union for Conservation of Nature) based on an assessment conducted in 1998. This assessment, however, was only based on the populations in Sumatra and Peninsular Malaysia. Therefore, this study aims to update the global conservation status of V. venulosa using all the occurrence records across the species’ natural distribution. Reduction analysis and geographic range of the species were calculated based on the occurrence data stored in the Global Biodiversity Information Facility and scientific publications. Following IUCN Red List Categories and Criteria, the category Vulnerable (VU A4c) was proposed as the new global conservation status of the species. Under this category, V. venulosa is facing a high risk of extinction in the wild. Therefore, comprehensive conservation action is needed to prevent it from extinction.
PRD-2 mediates clock-regulated perinuclear localization of clock gene RNAs within the circadian cycle of
Neurospora
Authors: Bartholomai Bradley M. , Gladfelter Amy S. , Loros Jennifer J. , Dunlap Jay C.
Published: July 2022

The transcription–translation negative feedback loops underlying animal and fungal circadian clocks are remarkably similar in their molecular regulatory architecture and, although much is understood about their central mechanism, little is known about the spatiotemporal dynamics of the gene products involved. A common feature of these circadian oscillators is a significant temporal delay between rhythmic accumulation of clock messenger RNAs (mRNAs) encoding negative arm proteins, for example,
frq
in
Neurospora
and
Per1-3
in mammals, and the appearance of the clock protein complexes assembled from the proteins they encode. Here, we report use of single-molecule RNA fluorescence in situ hybridization (smFISH) to show that the fraction of nuclei actively transcribing the clock gene
frq
changes in a circadian manner, and that these mRNAs cycle in abundance with fewer than five transcripts per nucleus at any time. Spatial point patterning statistics reveal that
frq
is spatially clustered near nuclei in a time of day–dependent manner and that clustering requires an RNA-binding protein, PRD-2 (PERIOD-2), recently shown also to bind to mRNA encoding another core clock component, casein kinase 1. An intrinsically disordered protein, PRD-2 displays behavior in vivo and in vitro consistent with participation in biomolecular condensates. These data are consistent with a role for phase-separating RNA-binding proteins in spatiotemporally organizing clock mRNAs to facilitate local translation and assembly of clock protein complexes.
Study of EIT line shape in optically thin and thick media using 87Rb D1 and D2 lines: theory and experiment
Authors: Das Chandan , Dey Sekhar , Ray Biswajit
Published: July 2022

In this work, we have presented the variation of the amplitude of electromagnetically induced transparency (EIT) resonances with the density of the atom in a V-type system using 87Rb D1 and D2 lines both theoretically and experimentally. Up to the value of atomic density 18.1 × 1010 cm−3, the amplitude of the EIT resonance gradually increases with the increase of atomic density and then it decreases with the increase of the density of the atom. We have also found the radiation trapping effect in this experiment. We observe the effect of the atomic density on the electromagnetically induced transparency when the systems act as a thin optical media as well as thick optical media. We have found that the amplitude of EIT also depends on pump laser Rabi frequency. Numerical simulations are agreed well with the experimental observations.
Efficient ILC analysis on polarization maps after EB leakage correction

Published: July 2022

The Internal Linear Combination (ILC) is widely used to extract the cosmic microwave background (CMB) signal from multi-frequency observation maps, especially for Satellite experiments with quasi-full sky coverage. We extend ILC method to CMB polarization map analysis with a small sky patch which is especially typical for ground-based experiments, by combing ILC with a template cleaning method which can give pure B map free from EB leakage caused by partial sky coverage. The feature of our methods is that we do the ILC analysis on pseudo-scalar B maps, and the advantage is that it totally avoids the impact of EB leakage on ILC, so that it can improve the efficiency of component separation dramatically. We demonstrate our methods with mock data of a future ground-based experiment with a deep survey on a clean patch in the northern sky, and the results show that the level of foreground residual can be well controlled, it biases the tensor to scalar ratio (r) at the order of 10-3 which is comparable to the statistical error by noise.
Glauber gluon effects in soft collinear factorization
Authors: Zhou Gao-Liang , Yan Zheng-Xin , Zhang Xin , Li Feng
Published: July 2022

Effects of Glauber gluons, which cause the elastic scattering process between different jets, are studied in the frame of soft-collinear effective theory. Glauber modes are added into the action before being integrated out, which is helpful in studies on the Glauber couplings of collinear and soft particles. It is proved that the final state interactions cancel out for processes inclusive enough. So are interactions with the light cone coordinates x
+ and x
− greater than those of the hard collision. The eikonalization of Glauber couplings of active particles and absorption of these couplings into soft and collinear Wilson lines are discussed, which is related to the loop level definitions of Glauber gluons here. The active-spectator coherence is proved to be harmless to the inclusive summation of spectator-spectator and spectator-soft Glauber exchanges. Based on this result, spectator-spectator and spectator-soft Glauber exchanges cancel out in the processes considered here. Graphic aspects of the cancellation are also discussed to explain relations between the graphic and operator level cancellation of Glauber gluons.

Published: July 2022

Deep learning techniques have been applied to the detection of gravitational wave signals in the past few years. Most existing methods focus on the data obtained by a single detector. However, the signal-to-noise ratio (SNR) of gravitational wave signals in a single detector is pretty low, making it hard for deep neural networks to learn effective features. Therefore, how to use the observation signals obtained by multiple detectors in deep learning methods is a serious issue. We simulate binary neutron star signals from multiple detectors, including the Advanced LIGO and Virgo detectors. We calculate coherent SNR of multiple detectors using a fully coherent all-sky search method and obtain the coherent SNR data required for our proposed deep learning method. Inspired by the principle of attention network Squeeze-and-Excitation Networks (SENet) and the soft thresholding shrinkage function, we propose a novel Squeeze-and-Excitation Shrinkage (SES) module to better extract effective features. Then we use this module to establish a gravitational wave squeeze-and-excitation shrinkage network (GW-SESNet) detection model. We train and validate the performance of our model on the coherent SNR data set. Our model obtains satisfactory classification accuracy and can excellently complete the task of gravitational wave detection.

Objective. The force that an electrocorticography (ECoG) array exerts on the brain manifests when it bends to match the curvature of the skull and cerebral cortex. This force can negatively impact both short-term and long-term patient outcomes. Here we provide a mechanical characterization of a novel liquid crystal polymer (LCP) ECoG array prototype to demonstrate that its thinner geometry reduces the force potentially applied to the cortex of the brain. Approach. We built a low-force flexural testing machine to measure ECoG array bending forces, calculate their effective flexural moduli, and approximate the maximum force they could exerted on the human brain. Main results. The LCP ECoG prototype was found to have a maximal force less than 20% that of any commercially available ECoG arrays that were tested. However, as a material, LCP was measured to be as much as 24× more rigid than silicone, which is traditionally used in ECoG arrays. This suggests that the lower maximal force resulted from the prototype’s thinner profile (2.9×–3.25×). Significance. While decreasing material stiffness can lower the force an ECoG array exhibits, our LCP ECoG array prototype demonstrated that flexible circuit manufacturing techniques can also lower these forces by decreasing ECoG array thickness. Flexural tests of ECoG arrays are necessary to accurately assess these forces, as material properties for polymers and laminates are often scale dependent. As the polymers used are anisotropic, elastic modulus cannot be used to predict ECoG flexural behavior. Accounting for these factors, we used our four-point flexure testing procedure to quantify the forces exerted on the brain by ECoG array bending. With this experimental method, ECoG arrays can be designed to minimize force exerted on the brain, potentially improving both acute and chronic clinical utility.

Herein we report variation in Tunnelling magneto resistance (TMR) of TM-porphyrin against increase in d electrons from n=1 to 8; as the transition metal changes across the periodic table from Sc to Ni. We observed that highest value of TMR is observed for d5 system the TMR becomes gigantic (1022) at the equilibrium and on either side of it we need to apply certain amount of energy to reach appreciable TMR. An even-odd oscillation of TMR is observed against the number of electrons in d orbital. We also observed that with even number of d electrons TMR values is on lower side and in many cases below the accepted range (150%) of an efficient TMR device. In fact, to achieve an acceptable range we need to apply relatively larger energy (as large as 0.7 eV for Ni) probably due to preference of low spin states in presence of even number of electrons in an atom. Observed feature has been explained using molecular orbital obtained in each case.

Lung carcinoma, generally known as lung cancer, is the most common cause of cancer which is related to mortality worldwide. Lung carcinoma is an extremely complex problem to solve and Lung cancer patients appear to be the most vulnerable to SARS-CoOVID-19 infection early discovery, on the other hand, has a high rate of survivability. Lung carcinoma detection in computed tomography (CT) has emerged as an emerging research subject in the field of medical imaging systems in recent years. The ability to accurately detect the size and location of lung cancer plays a critical role in lung cancer diagnosis. As a result, there is a requirement to rapidly read, detect, classify and evaluate CT scans. In this paper, we suggest a method for detecting and classifying lung nodules (or lesions) using a multi-strategy system. It has two parts: nodule detection (finding nodules) and classification (classifying nodules into Benign / non-cancerous or Malignant / cancerous). Lung CT scan images are utilized to detect and classify lung nodules in this work. U-Net architecture is used to segment CT scans, while VGG Net is tested on 3D images derived from LUNA 16 and LIDC - IDRI. The U-Net and the VGG-Net results are combined in the final findings.

Encryption of remote sensing images is always required as this type of images carry sensitive data. It is the primary criteria to hide it in case of a country’s border image or video. Nowadays development in networking improves communication systems. Unfortunately, intruders are misusing this advantage and try to intrude into the network whose security is weak. During secure communication of remote sensing images, encryption is done before sending to a long distance. Here, we have discussed a new method of remote sensing image encoding with the help of hamming code. During analyzation, we have showed that it is not easy to decode the main image from encrypted data in the most popular mode of attacking- known plaintext attack. Moreover, we have also calculated that this system can detect the error in an effective way. The presented method is also applicable for effective encryption of more than one remote sensing images.

In recent years the realization and growing awareness of energy consumers regarding the environmental issues, economic and climatic challenges have accelerated a strong sustain impact in developing power technologies. To mitigate the detrimental impacts of the conventional energy resources, this paper provides an idea about an off-grid, distributed solar-piezo power generating technique usable for residential & isolated area applications. The primary power is supplied by the solar panel, and the subordinate power can be added by the produced energy from the piezoelectric modules, and the battery model is employed for continuous power supply in the suggested hybrid renewable power system.Furthermore, the dc-dc boost converter for PV and piezoelectric modules is designed to connect two power inputs in parallel. The present study focuses upon the design of the proposed system & scopes of the proposed system in Tripura, a hilly state in the North-Eastern Province of India.Tripura has ranked 56th amongst 100 smart cities in the countryaccording to Smart City rankings released in July 2020 & also 1st among all the North-Eastern states. Thus, the motto of the paper is to draw attention towards implementation of green energy harvesting techniques in Tripura which will certainly help to mitigate the techno-economic barriers in the region &successfully mitigating the energy requirements. The modelling and simulation of the proposed hybrid arrangement has been carried out in MATLAB/SIMULINK. The analysis of the proposed system portrays the effectiveness of the proposed system.

Published: July 2022

During the COVID-19 pandemic lockdown, Italian schools and Universities were closed. In this scenario, teachers, in order to continue their work, had to manage the didactics by themselves, carrying out Distance Learning, thanks to the technology support. Nevertheless, teachers had some methodological and technical difficulties. This situation required the replanning of some physics contents, trying to include laboratory activities, too. A teachers’ training was organized in order to support the teachers both for effective and meaningful use of ICT and to carry out some laboratory activities in Distance Learning mode. The training aimed to investigate leading technologies relevant to physics teaching, the competencies that a physics teacher has to acquire to use digital technologies, and the effective approaches to develop these competencies. The course was organized into four webinars, timing 10 hours. Teachers became confident with ICT for communication, sharing, and documentation. Moreover, teachers approached the IBSE methodology, as modified by adding a further E-laboratory phase to the 5E cycle, promoted by Bybee, by planning a learning chunk, including a laboratory activity in synchronous e-learning mode. 20 High School Physics teachers were involved in the training.

Published: July 2022

From a physicist point of view, Virtual Reality setups are high-precision, low-cost, 6 degrees-of-freedom, high-speed, multiple-objects tracking devices. These setups prove to be very high-quality sensors that are well suited to be used in the physics laboratory for tracking in motion experiments. Augmented Reality can be achieved by attaching a stereo to the headset to allow students to see the 3D tracking of the experiment in the physical world. A series of Augmented Reality Active Learning (AnReAL) activities are presented, while also comparing this setup to more traditional ones, i.e. ultrasonic motion sensors and video tracking analysis software. Virtual and augmented reality setups, such as the presented one, are likely to prove very beneficial for information retention, following the emerging theory of embodied cognition.
