The Effects of Captioning Errors, Background Noise, and Hearing Loss on Memory for Text-Captioned Speech
Authors: Crandell Hannah A. , Silcox Jack W. , Ferguson Sarah H. , Lohani Monika , Payne Brennan R. 
Published: May 2022

Purpose:
Previous studies have suggested that the negative effects of acoustic challenge on speech memory can be attenuated with assistive text captions, particularly among older adults with hearing impairment. However, no studies have systematically examined the effects of text-captioning errors, which are common in automated speech recognition (ASR) systems.

Method:
In two experiments, we examined memory for text-captioned speech (with and without background noise) when captions had no errors (control) or had one of three common ASR errors: substitution, deletion, or insertion errors.

Results:
In both Experiment 1 (young adults with normal hearing) and Experiment 2 (older adults with varying hearing acuity), we observed similar additive effects of caption errors and background noise, such that increased background noise and the presence of captioning errors negatively impacted memory outcomes. Notably, the negative effects of captioning errors were largest among older adults with increased hearing thresholds, suggesting that older adults with hearing loss may show an increased reliance on text captions compared to adults with normal hearing.

Conclusion:
Our findings show that even a single-word error can be deleterious to memory for text-captioned speech, especially in older adults with hearing loss. Therefore, to produce the greatest benefit to memory, it is crucial that text captions are accurate.
Reevaluating the Use of Sound Therapy for Tinnitus Management: Perspectives on Relevant Systematic Reviews
Authors: Henry James A. , Carlson Kathleen F. , Theodoroff Sarah , Folmer Robert L. 
Published: May 2022

Purpose:
Tinnitus is a highly prevalent condition that can severely reduce health functioning. In spite of extant clinical practice guidelines (CPGs), implementation of these CPGs is relatively uncommon. As a result, patients seeking professional services for tinnitus often have no assurance of receiving evidence-based care. The purpose of this tutorial was to clarify the evidence for sound therapy so that it may be included in future CPGs for tinnitus.

Method:
“Best clinical evidence” is obtained from high-quality systematic reviews, which are generally considered the highest level of evidence. Our review of recent, comprehensive, high-quality systematic reviews of interventions for tinnitus concludes that cognitive behavioral therapy is the only effective intervention, though the strength of evidence was generally rated as low in these reviews. Although trials of sound therapy for tinnitus have been included in these reviews, they have been rated as having high risk of bias (RoB) and not included in syntheses or rated as insufficient strength of evidence.

Results:
Conclusions from these and other reviews have influenced recommendations made in CPGs for tinnitus. These conclusions, however, can make it appear that an intervention for tinnitus is not effective, even if the opposite is true. We contend that the strict inclusion criteria for these reviews are counterproductive and have the effect of obscuring decades of evidence demonstrating the clinical effectiveness of sound therapies for tinnitus. Ultimately, this process has resulted in many patients not receiving sound therapy, despite what should be sufficient evidence that this is an effective form of intervention.

Conclusion:
If we rely on systematic reviews using contemporary RoB assessment criteria for studies published prior to these reporting guidelines, then we risk excluding important conclusions regarding interventions that could help patients in need.

AbstractOne of the critical challenges in multicarrier‐based systems is peak to average power ratio (PAPR). Recently, Filter Bank Multicarrier (FBMC) is proved to be a promising candidate that can replace the traditional orthogonal multiplexing division (OFDM) scheme due to its better spectral efficiency, reducing both inter‐channel interference (ICI) and PAPR. Due to their advantages in reducing the PAPR without impacting the BER, the Hadamard transform was used in the proposed FBMC based VLC system. Furthermore, here, the discreet cosine transform (DCT) precoding is also used to boost the potential for PAPR reduction and the BER efficiency. The negative signals are not clipped off as in traditional asymmetrically‐clipped optical OFDM (ACO‐OFDM) signals to reduce the impact of large‐amplitude signal reduction nor add dc biasing for cancelling negative signals as in traditional DC‐biased optical OFDM (DCO‐OFDM) signals. Furthermore, a Clipping ratio is introduced to allow a trade‐off between bit error rate (BER) and PAPR reduction, and the optimal PAPR reduction is investigated. The obtained results show that the proposed FBMC based VLC system with DCT and clipping technique can reduce the PAPR and achieve good BER efficiency compared to the OFDM based VLC system.

Published: May 2022

AbstractPoint cloud data in the real world is often affected by occlusion and light reflection, leading to incompleteness of the data. Large‐region missing point clouds will cause great deviations in downstream tasks. A dual feature fusion network (DFF‐Net) is proposed to improve the accuracy of the completion of a large missing region of the point cloud. First, a dual feature encoder is designed to extract and fuse the global and local features of the input point cloud. Subsequently, a decoder is used to directly generate a point cloud of missing region that retains local details. In order to make the generated point cloud more detailed, a loss function with multiple terms is employed to emphasise the distribution density and visual quality of the generated point cloud. A large number of experiments show that the authors’ DFF‐Net is better than the previous state‐of‐the‐art methods in the aspect of point cloud completion.
A memristor‐based associative memory circuit considering synaptic crosstalk
Authors: Li Zhijun , Yi Zhaowei 
Published: May 2022

AbstractSynaptic crosstalk, which characterises the interaction between synapses when the neighbouring neurons are activated at the same time, plays an important role in the transmission of neural signals. To discover the effect of synaptic crosstalk on associative memory, a memristor‐based associative memory circuit considering synaptic crosstalk is proposed in this letter. The inhibitory effect of negative crosstalk on associate memory in the initial learning stage and the consolidation influence of positive crosstalk on associate memory when the synaptic weight exceeds its critical value are revealed. Pspice simulations are conducted on the resultant circuit to verify its correctness.

Published: May 2022

AbstractThis paper demonstrates how to consider thermal reserves of overhead lines in optimization problems for congestion management with preventive (pre‐fault) and curative (post‐fault) actions effectively to ensure N‐1 security. Solving congestions curatively allows for higher base loadings and reduced congestion management volumes. At the same time, assets are exposed to higher risks of damage. The two proposed methods incorporate precise permanent and temporary admissible loading constraints for base and contingency situations already at the operational planning stage. The methods ensure that conductor temperatures stay below the assets’ thermal limits at all times. The benefits of exploiting thermal reserves are analyzed in a case study to the future German transmission grid of 2030.

Published: May 2022

AbstractThis paper investigates the problem of robust dynamic output feedback control of 3‐phase 4‐wire converter with neutral bridge arm in the application of smart grid and distributed generation. Based on Lyapunov functions, a novel sufficient Linear Matrix Inequality condition analysis was performed on the dynamic output feedback stabilisation controllers. Meanwhile, some auxiliary slack variables with special structure and well‐established performance conditions are employed to reduce design conservatism. This topology along with the controller can solve the DC link balancing problem and maintain the deviation between the neutral point and the midpoint of DC supply very small. The achievable performance is analysed quantitatively and the controller design method was conducted and verified both in MATLAB simulation and the real‐time simulation platform built by StarSim and MT, respectively.

Published: May 2022

AbstractRenewable generation uncertainty, dynamic load change, and system parameter variation play a significant role in the performance degradation of non‐linear multi‐microgrid (MMG) systems. As a result, intelligent control becomes the need of the hour for assisting superlative attribute‐ based consistent electric power. The application of marine predator algorithm (MPA)‐based cascaded PD‐(1+PI) controller for Automatic Generation Control (AGC) of MMG system is a novel work. A maiden attempt of the MPA is proposed to optimize the parameters of the cascaded PD‐(1+PI) controller using the integral time absolute error criterion. To demonstrate its superiority, the proposed algorithm is compared to the genetic algorithm, differential evolution, and grey wolf optimization. MPA then applied to conventional controller PID, cascaded PD‐PI controller and proposed PD‐(1+PI) controller for frequency control in multi‐microgrid system. The robustness of the suggested controller is verified over PID and PD‐PI controller by taking step and random load perturbation and integrating the renewable sources like solar and wind with their uncertain nature. The simulation of the investigated interconnected microgrid is carried out in MATLAB/SIMULINK environment. Finally, detailed simulation and hardware in the loop experimental results are presented to confirm the practicality of the proposed approach.
Stochastic forecast error estimation of high PV penetration system considering net‐load/PV decoupling for microgrid operation

Published: May 2022

AbstractThe increase of distributed Photovoltaic (PV) generators in the power system changes the load demand pattern as some of them are located behind the meter (BtM). As known as BtM PV generators, the impact on netload demand pattern increases the uncertainty of scheduling and balancing of the power system. The distortion of load demand by BtM PV must be decoupled to make an accurate forecast model for the load. In this paper, the impact of BtM PV on stochastic forecast error (SFE) is analyzed and verified how they change the efficiency of microgrid operation. The net load pattern and solar irradiation data are collected and used to decouple BtM PV distortion by using K‐mean clustering and support vector machine regression analysis. Then, the baseload demand and solar irradiation forecast model is built using recurrent neural networks with external input parameters. Using the forecast model, the correlation between distributions of forecast and forecast error is built as a joint probability distribution. The SFE is modeled as conditional forecast error in a form of a probability density function and used for microgrid scheduling optimization. Case studies are based on data acquired from global data assimilation and prediction system (GDAPS) and local transmission system operator (TSO) at Jeju island in Korea.

Published: May 2022

AbstractThis paper introduces a discrete Fourier transform (DFT)‐based method for estimating the amplitudes and frequencies of interharmonics, which arise from the interaction between wind power generators and electric power systems. This method exploits the synergy of choosing signal enhancement, mains frequency estimation, and re‐sampling techniques. Consequently, it accomplishes a cost‐effective estimation process. The performance results show that signal enhancement and re‐sampling techniques are necessary to establish suitable conditions for performing amplitude and frequency estimation. Furthermore, numerical results show that the proposed method, relying on low‐cost digital signal processing techniques, offers competitive performance and significant computational complexity reduction compared to a previous DFT‐based method.

Abstract
Objective The presence of an extensive intraductal component is associated to an increasing risk of relapse in the nipple-areola complex. The aim of the present study was to evaluate the outcomes of patients diagnosed with ductal carcinoma in situ (DCIS) who underwent nipple-sparing mastectomy (NSM) with immediate breast reconstruction using silicone implants.
Methods We retrospectively analyzed the postoperative complications and oncological safety of 67 breast cancer patients diagnosed with pure DCIS who underwent NSM with immediate breast reconstruction using silicone implants between 2004 and 2018.
Results Among the 127 NSM procedures performed, 2 hematomas (1.5%) and 1 partial nipple necrosis (0.7%) were observed. After a mean follow-up of 60 months, the local recurrence rate was of 8.9%, the disease-free survival rate was of 90%, and 1 of the patients died.
Conclusion Despite the local recurrence rate, we showed that NSM with immediate breast reconstruction using silicone implants is a feasible surgical approach, with a low rate of complications and high survival rates for patients with a diagnosis of pure DCIS when breast-conserving surgery is not an option.

Published: May 2022

AbstractPulmonary infections are the major cause of morbidity and mortality in immunocompromised patients and almost one-third of intensive care unit patients with pulmonary infections belong to the immunocompromised category. Multiple organisms may simultaneously infect an immunocompromised patient and the overwhelming burden of mixed infections further predisposes critically ill patients to acute hypoxemic respiratory failure. Notwithstanding that lung ultrasound is coming into vogue, the primary imaging investigation is a chest radiograph, followed by thoracic CT scan. This review based on our experience at tertiary care teaching hospitals provides insights into the spectrum of imaging features of various pulmonary infections occurring in immunocompromised patients. This review is unique as, firstly, the imaging spectrum described by us is categorized on basis of the etiological infective agent, comprehensively and emphatically correlated with the clinical setting of the patient. Secondly, a characteristic imaging pattern is emphasized in the clinical setting-imaging-pattern conglomerate, to highlight the most likely diagnosis possible in such a combination. Thirdly, the simulating conditions for a relevant differential diagnosis are discussed in each section. Fourthly, not only are the specific diagnostic and tissue sampling techniques for confirmation of the suspected etiological agent described, but the recommended pharmaco-therapeutic agents are also enumerated, so as to provide a more robust insight to the radiologist. Last but not the least, we summarize and conclude with a diagnostic algorithm, derived by us from the characteristic illustrative cases. The proposed algorithm, illustrated as a flowchart, emphasizes a diagnostic imaging approach comprising: correlation of the imaging pattern with clinical setting and with associated abnormalities in the thorax and in other organs/systems, which is comprehensively analyzed in arriving at the most likely diagnosis. Since a rapid evaluation and emergent management of such patients is of pressing concern not only to the radiologist, but also for the general physicians, pulmonologists, critical care specialists, oncologists and transplant surgery teams, we believe our review is very informative to a wide spectrum reader audience.

Published: May 2022

AbstractAs one of the fatal complications, venous thromboembolism (VTE) is associated with increased mortality. However, the combined effects of adopting multiple healthy lifestyles have not been firmly demonstrated. This study was to evaluate the association of combined healthy lifestyles and genetic risk factors with VTE and to investigate their interaction. A prospective cohort study from UK Biobank with a total of 442,963 men and women aged between 38 to 73 years were recruited from 2006 to 2010 and followed up through 2017 or 2018. A polygenic risk score was constructed and a weighted healthy lifestyle score, including no current smoking, regular physical exercises, healthy diet, and healthy body mass index, was categorized. During a median follow-up 9.0 years (3,912,396 person-years), there were 6,736 (172 per 100,000 person-years) incident VTE cases recorded. Among the participants with an unfavorable lifestyle, 1.80% developed VTE, versus 1.03% of the participants with a favorable lifestyle (hazard ratio [HR]: 1.58; 95% confidence interval [CI]: 1.48–1.68). Of the participants with high genetic risk, 2.42% developed VTE, versus 0.97% of the participants with low genetic risk (HR: 2.60; 95% CI: 2.39–2.81). Moreover, of the participants with high genetic risk and unfavorable lifestyle, 2.90% developed VTE, versus 0.66% of the participants with low genetic risk and favorable lifestyle (HR: 4.09; 95% CI: 3.48–4.79). No significant interaction between genetic risk and lifestyle factors was observed (p for interaction = 0.727). An unfavorable lifestyle was associated with a substantially higher risk of VTE, regardless of the genetic risk strata.

Published: May 2022

Objective The aim of this study was to quantify the influence of maternal sociodemographic, medical, and pregnancy characteristics on not receiving maternal and neonatal interventions with deliveries occurring at 22 to 23 weeks of gestation.
Study design This was a case–control study of U.S. live births at 220/6 to 236/7 weeks of gestation using vital statistics birth records from 2012 to 2016. We analyzed births that received no interventions for periviable delivery. Births were defined as having no interventions if they did not receive maternal (cesarean delivery, maternal hospital transfer, or antenatal corticosteroid administration) or neonatal interventions (neonatal intensive care unit admission, surfactant administration, antibiotic administration, or assisted ventilation). Logistic regression estimated the influence of maternal and pregnancy factors on the receipt of no interventions when delivery occurred at 22 to 23 weeks.
Results Of 19,844,580 U.S. live births in 2012–2016, 24,379 (0.12%) occurred at 22 to 23 weeks; 54.3% of 22-week deliveries and 15.7% of 23-week deliveries received no interventions. Non-Hispanic Black maternal race was associated with no maternal interventions at 22 and 23 weeks. Private insurance, singleton pregnancy, and small for gestational age were associated with receiving no neonatal interventions at 22 and 23 weeks of gestation.
Conclusion Withholding or refusing maternal and neonatal interventions occurs frequently at the threshold of viability. Our data highlight various sociodemographic, pregnancy, and medical factors associated with decisions to not offer or receive maternal or neonatal interventions when birth occurs at the threshold of viability. The data elucidate observed practices and may assist in the development of further research.

Unicortical Bone Necrosis of the Fibula Free Flap Associated to the Fixation with a Nonlocking 2.0-mm Reconstruction Plate and Screws
Authors: Pereira Gustavo N. , Ribeiro Diogo , Saraiva Luís , Freitas Hugo , Santos Ana R. 
Published: May 2022

AbstractThe authors present a unique case of osteonecrosis of a cortical half of a fibula free flap that has not been reported in the literature yet. This complication was associated with the impairment of the vascularization of periosteum in the cortical half of fibula that was fixated with a nonlocking reconstructive 2.0-mm plate and screws but other factors could have been involved. The patient was submitted to excision of a cemento-ossifying fibroma that resulted in a left hemimaxilectomy mesoinfrastructure defect classified as the Cordeiro type 2B. The 42-year-old female patient was submitted to reconstruction with an osteomusculocutaneous fibula free flap plus a segment of fibula graft. The two bone segments of the free flap used to reconstruct the anterior and left alveolar crest were fixated with a reconstructive 2.0-mm plate of matrixMANDIBLE system. The only reported complication was an oronasal fistula that healed with conservative treatment and the referred osteonecrosis of the external cortical half of the fibula free flap with plate exposure at 2.5 years postoperatively. Surgical excision of the osteonecrosed cortical half of the fibula with the plate and screws was performed, while the other cortical underwent bone union as corroborated by computed tomography scans.
