Acoustic Echo Suppression Using Speech Uncertainty In Modulation Domain
Authors: Shifas Muhammed PV , EP Jayakumar , PS Sathidevi
Published: June 2021

Quality degradation of near end speech in mobile communication or hands free devices is mainly due to acoustic echoes and background noises. The received far-end speech gets reflected from the obstacles present in the surroundings creating acoustic echo. All other disturbances from the near end environment are considered as background noises. A novel acoustic echo suppression scheme using speech uncertainty in modulation domain (MD) is proposed in this paper. State of the art acoustic echo suppression systems are based on either time domain or frequency domain analysis. In recent times, the modulation domain analysis is popularly used in speech processing, as it captures the human perceptual properties. Modulation domain provides the temporal variation of the acoustic magnitude spectra which acts as an information bearing signal. In this paper, a new method is developed and implemented to model the echo path and estimate the echo in modulation domain. Echo cancellation is done effectively by manipulating the modulation spectrum and employing speech uncertainty. In this method, the microphone input is modelled as a binary hypothesis process and the gain function is modified accordingly. The proposed method shows better performance as compared to other competitive methods for acoustic echo suppression with no audible degradation in the near end speech.
An Attention Based Hierarchical LSTM Architecture for ECG Biometric System
Authors: Jyotishi Debasish , Dandapat Samarendra
Published: June 2021

The electrocardiogram (ECG) based biometric sys-
tem has recently gained popularity. Easy signal acquisition and
robustness against falsification are the major advantages of the
ECG based biometric system. This biometric system can help
automate the subject identification and authentication aspect of
personalised healthcare services. In this paper, we have designed
a novel attention based hierarchical long short-term memory
(LSTM) model to learn the biometric representation correspond-
ing to a person. The hierarchical LSTM model proposed in this
paper can learn the temporal variation of the ECG signal in
different abstractions. This addresses the long term dependency
issue of the LSTM network in our application. The attention
mechanism of the model learns to capture the ECG complexes
that have more biometric information corresponding to each
person. These ECG complexes are given more weight to learn
better biometric representation. The proposed system is less
complex and more efficient as it does not require the detection
of any fiducial points. We have evaluated the proposed model for
both the person verification and identification problems using
two on-the-person ECG databases and two off-the-person ECG
databases. The proposed framework is found to perform better
than the existing fiducial and non-fiducial point based methods.

Published: June 2021

Artificial Intelligence (AI) models can learn from data and make decisions without any human intervention. However, the deployment of such models is challenging and risky because we do not know how the internal decision- making is happening in these models. Especially, the high-risk decisions such as medical diagnosis or automated navigation demand explainability and verification of the decision making process in AI algorithms. This research paper aims to explain Artificial Intelligence (AI) models by discretizing the black-box process model of deep neural networks using partial differential equations. The PDEs based deterministic models would minimize the time and computational cost of the decision-making process and reduce the chances of uncertainty that make the prediction more trustworthy.

Authors: Rajesh Sonkusare
Published: June 2021

In the history of a great country like India, there have been many rulers since ancient times who ruled different regions of India at different times. But few of these rulers are called great rulers. Maurya ruler Chandragupta Maurya and Emperor Ashoka, Gupta ruler Chandragupta II (Vikramaditya), Vardhana ruler Harshavardhana, Kushan emperor Kanishka, Satavahana ruler Gautamiputra Satkarni, Chalukya ruler Pulakeshi II, Chola rulers Rajaraja Chola and Rajendra Chola, Rashtrakuta ruler Amoghvarsh, Pratihar ruler Mihira bhoja, Mughal emperor Jalaluddin Muhammad Akbar are named.
Among these great rulers of India were two rulers whose lives and work were very similar. The rulers were the Gupta emperor Chandragupta II (Vikramaditya) and the Mughal emperor Jalaluddin Muhammad Akbar.
The similarity between Chandragupta II (Vikramaditya) and Jalaluddin Mohammad Akbar is that the grandfather of both the rulers was the real founder of their kingdom. Both the rulers came to power through struggle (war). Both the rulers were tolerant rulers. The empire of the two rulers extended from present day Pakistan in the north to the mouth of the river Narmada in the south and from the mouth of the river Ganga in the east to the mouth of the river Indus in the west. Art, architecture, etc. developed during the reign of both the rulers. Due to the excellent administrative system of both the rulers, their empire remained stable for many generations to come. The main similarity between the two rulers is that in the history of India, only this two rulars have the Navratna in their court.

The major objective of this study is to identify the impact of inland transport service quality on passengers' satisfaction. The present study has been attempted to understand and examine the factors influencing the passenger’s satisfaction in the Launch Service. The study is exploratory in nature and used factor analysis to identify the foremost significant factors of Passenger’s satisfaction with service quality. By questionnaire survey we put our survey into five category those are tangibility, reliability, responsiveness, assurance, empathy (24 type question). Also, we took a part in photography survey. From photography and questionnaire survey we made a data and put that data into analysis. By analysis the data we made some pie chat and find a result. Though the satisfaction level is not good. From the result it is shown that bollard quality, dock railing system, mooring ropes quality, staff accommodation; those four parts of the launch terminal is very poor. Although bollard quality, cleanliness, dock to dock joint, snapback zone, watchtower service; those five parts of launch terminal is poor. Also, the docking system, lighting system, loading and unloading system, security system for passenger’s, hawker’s volume, terminal maintenance is average; those five parts of launch terminal is good. It is disappointing to say that there isn’t any canteen facility for the passengers. The rest of the part of the launch terminal is good. We also recommended some suggestion which improvement could make a far better passenger’s satisfaction.

Deformability of Erythrocytes is maintained after Autologous Cell Salvage in Orthopedic Surgery
Authors: Kietaibl Sibylle
Published: June 2021

Background and Objective: Prerequisite for oxygen transport to the tissue is the ability of erythrocytes to change from a discoid into an elongated form in order to pass microvessels. Cell salvage is highly recommended to decrease blood loss and to avoid allogeneic transfusions in perioperative bleeding. The purpose of our study was to assess deformability of erythrocytes at re-transfusion.

Materials and Methods: After ethics committee approval and informed consent, blood was withdrawn from the autotransfusion system (Xtra, Sorin, Germany) of 24 patients undergoing joint arthroplasty 6 hours after cell salvage initiation. Deformability curves, elongation indices (EI) obtained at increasing shear stress (SS) were assessed by using Laser Optical Rotational Red Cell Analysis (LORRCA).

Results: Erythrocytes showed the typical sigmoid EI/SS curve with a mean maximum elongation index (EImax) of 0.593 ± 0.034 and mean half-maximal deformation (SS ½) of 1.186 ± 0.387 Pa. Irregular curve shapes and high variability in EI occurred at shear stress < 3 Pa. Recalculation of outcome parameters resulted in higher values (EImax 0.610 ± 0.035; SS ½ 1.562 ± 0.346 Pa).

Conclusion: Erythrocytes after autologous cell salvage are not stiff but elongate in response to shear stress. Erythrocytes showed the typical EI/SS-curve of human red cells, which indicates that the cells are able to uptake the hydrodynamic forces that act on them during the measurement. Further research is needed to investigate the effect of cell salvage processing on erythrocytes from patients with pre-existing hematological disorders.

Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Common signs of corona virus infection include respiratory symptoms, fever, and cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death. People who are suffering from prevailing chronic diseases such as cancer, heart disease, high blood pressure, diabetes, chronic kidney disease, etc. may die due to their weaker immunity system. Most of the people around the world died due to panic attack and due to extreme fear. A fear of not having vaccination for the virus infections has also taken a big death toll. Therefore, it is very important to build a stronger robust immune system and patients need to think positive and follow the positive approach to combat the disease.

Device-Detected Subclinical Atrial Fibrillation and Increased Stroke Risk
Authors: Vetta Francesco
Published: June 2021

Atrial fibrillation (AF) is one of the major causes of stroke. Data from the literature show that among the causes of stroke 60% is attributable to cerebrovascular diseases, 15% to AF, while about 25% of cases do not identify recognizable causes. The technological advancement of cardiac implanted electronic devices has enabled the identification of subclinical atrial fibrillation (SCAF). The literature shows that SCAF is very frequent in the elderly population and that it represents a risk factors for the onset of stroke or systemic embolic disease, regardless of other cardiovascular risk factors. While for clinical atrial fibrillation (AF) the advantages of anticoagulant therapy based on the CHA2DS2-VASCscore have been well established, much less is known about the usefulness of anticoagulant therapy in the case of SCAF. The role of the CHA2DS2-VASCscore is much debated, although recently a study has clearly shown that the number and duration of SCAF episodes together with the CHA2DS2-VASC score plays an important role in determining the risk of progression to a persistent AF. Based on these data, the ongoing ARTESIA and AFNET-NOAH studies will provide us with data to evaluate the net clinical benefit of anticoagulation in SCAF.

Published: June 2021

Pulmonary arterial hypertension is a progressive and ultimately fatal disease despite the availability of a number of new therapies, including endothelin receptor antagonists. Many side effects have been reported with the use of these drugs, such as hepatotoxicity, peripheral edema, anemia and other digestive reactions. Cardiac side effects have been rarely mentioned. We report the case of a 17-year-old girl with Eisenmenger syndrome secondary to double outlet right ventricle and sub-pulmonary ventricular septal defect, Macitentan treatment has been started, three days later, she presented a ST segment elevation in septo-apico- lateral territory which shortly complicated with cardiogenic shock and death. A coronary arteritis or acute myocarditis of toxic origin was the two evoked diagnoses. This is the first human case in the medical literature describing a relationship between initiation of Macitentan and the onset of this event. This case highlights a lethal side effect of Macitentan, which should prompt patients to notify their doctors of any symptoms suggestive of coronary or myocardial injury (chest pain, dyspnea, heart failure symptoms), and implementation of electrocardiogram in combination with a control in any patient who develops chest pain on Macitentan.

Published: June 2021

Oral anticoagulation based on anti-vitamin K is prescribed in the prevention and treatment of thromboembolic events, but it could bring up a significant hemorrhagic risk. This study aims at describing the epidemiological, clinical and evolutionary features of the hemorrhagic accidents to VKA. It is a retrospective descriptive study carried out at the Cardiology Department of Casablanca’s University Hospital of IbnRochd over a two-year period including 33 patients hospitalized for AVK-hemorrhagic accidents. Asymptomatic overdoses were excluded. In our sample the average age was 50 years with a sex ratio of 1.7 (21 Male/12 Female). There has been evidence of multi-morbid field of patients with several involved histories. Acenocoumarol was the prescribed molecule for all patients. Mechanical valve prostheses were the main indication of anticoagulant treatment (60%). More than half of patients were not regularly monitored. Polymedication was found in the majority of cases (78%), with an association with amiodarone in 20% of cases, and with anti-aggregation treatment in 10% of cases. Soft parts’ Hematomas and digestive hemorrhages were the most frequent forms of hemorrhagic accidents. Hemodynamic instability was found in two patients. The therapeutic conduct was different depending upon the case, but focused on stopping AVKs, administration of vitamin K, transfusion of blood cells and fresh frozen plasma. 86% of cases displayed a good evolution, with a mortality rate of 13% during the acute phase of the hemorrhagic accident. In conclusion, prevention of these accidents is the pillar of care, which puts forward the importance of informing and educating the various stakeholders in this potentially fatal iatrogenic complication. Considering the severity of bleeding under KVA, new direct oral anticoagulants may be a good alternative in some indications.

Mutualistic association between Azteca Forel, 1878 ants and Cecropia Loefl. plants are one of the most studied interactions in Neotropics, however, natural history studies of Azteca species still poorly investigated due to the great effort required to conduct detailed descriptive studies. Here, we describe biological aspects of Azteca muelleri Emery, 1893 nesting in Cecropia glaziovii Snethl. in a fragment of Atlantic Forest, addressing (a) colony size; (b) nest distribution on the tree; and (c) worker and queen morphometrics. We collected two C. glaziovii saplings and counted characteristics of the nests and plants. We randomly selected 140 workers to measure and to determine whether intraspecific polymorphism occurs. Workers, immatures, and mealybugs were present in all hollow internodes of plant, and a queen was found. We found isometric morphological variation in A. muelleri. Our study provides new data to understand the biology of A. muelleri nesting in C. glaziovii, one of the most species-rich genera of arboreal ants known for the neotropics.

Demencijos sindromas – tai lėtinis progresuojantis neurodegeneracinės kilmės pažeidimas, kuris pasireiškia laipsnišku kognityvinių funkcijų netekimu bei galimu elgesio sutrikimu. Laiku pradėtas gydymas ir tam tikri gyvenimo būdo pokyčiai prailgina pradines ligos stadijas bei lėtina kognityvinių funkcijų netekimą. Lietuvoje gyventojų amžiaus struktūros tipas yra regresyvus, todėl tiksli demencijos sindromo diagnostika bei sergančiųjų skaičius tampa labai aktualūs siekiant pagerinti sveikatos bei socialinės priežiūros paslaugas. Tyrimo tikslas. Apskaičiuoti tikėtinai nediagnozuotų demencijos atvejų skaičių Lietuvoje ir įvertinti sveikatos priežiūros paslaugų poreikį sergantiesiems demencija. Metodai. Demencijos sindromo epidemiologijos Lietuvoje analizei taikyti Higienos instituto sveikatos statistinių duomenų portalo bei Lietuvos statistikos departamento – oficialiosios statistikos portalo duomenys. Tikėtinai nediagnozuotų demencijos sindromu sergančiųjų skaičius buvo apskaičiuotas naudojantis EuroCoDe 2008 projekto rezultatais. Rezultatai. Lietuvoje užregistruotų sergančiųjų demencija skaičius nuo tikėtinai nediagnozuotų skiriasi net 17857 atvejais. Būtina nuolatinė priežiūra ir globa, tikėtinai, reikalinga 10860 registruotų sergančiųjų, o jei Lietuvoje demencijos sindromo diagnostika būtų pakankama, tikėtina, tokių ligonių, kuriems reikalinga nuolatinė priežiūra, globa ir slauga, būtų 1,7 karto daugiau. Išvados. Lietuvoje demencijos sindromo atpažinimas ir diagnozavimas nepakankami.

Skiepo nuo COVID–19 sukūrimo greitis tapo precedento neturinčiu reiškiniu medicinos istorijoje [7, 8]. Tiek klinikinių tyrimų metu, tiek pradėjus rizikos grupių asmenų skiepijimą, labai daug diskusijų kelia nepageidaujamos reakcijos, jų dažnis ir sunkumas. Žiniasklaidoje analizuojami sunkių sveikatos sutrikimų atvejai, siejami su skiepais, didina visuomenės baimę skiepytis, o oficiali Lietuvoje registruojamų nepageidaujamų reakcijų į skiepus statistika, galimai netiksli. Šiomis aplinkybėmis šeimos gydytojams labai svarbūs klinikinės praktikos mokslinių tyrimų duomenys, kurie leistų numatyti nepageidaujamas reakcijas pacientams bei veiksmingai jas valdyti. Tyrimo tikslas. Nustatyti nepageidaujamas reakcijas, jų pasireiškimo aplinkybes po COVID–19 skiepų. Tyrimo uždaviniai. 1. Nustatyti nepageidaujamų reakcijų į COVID–19 vakciną pasireiškimo laiką ir intensyvumą. 2. Įvertinti nepageidaujamų reakcijų įtaką darbingumui. Metodika. Tyrimas vykdytas Lietuvos sveikatos mokslų universiteto ligoninėje Kauno klinikų (toliau – Kauno klinikos) laikinai įkurtame vakcinavimo nuo COVID–19 centre 2021 m. vasario–kovo mėn. Tyrimo dalyviai: antrajai vakcinos dozei atvykę suaugusieji, informuoti apie tyrimo tikslą bei eigą, savanoriškai užpildę anoniminę anketą apie patirtas nepageidaujamas reakcijas po pirmosios vakcinos dozės. Anketą sudarė 20 įvairaus tipo klausimų, pateiktos pasireiškusių nepageidaujamų reakcijų vertinimo skalės su įverčiais nuo 1 (pasireiškė nežymiai) iki 5 (pasireiškė labai stipriai). Statistinė analizė atlikta naudojant „SPSS 26.0 for Windows“ duomenų apdorojimo paketą. Rezultatai ir išvados. 1. Iš 4344 apklaustųjų simptomai po skiepo pasireiškė 2305 (53,1 proc.) (19,2 proc. vyrų ir 80,8 proc. moterų). 2. Daugiausia nepageidaujamų reiškinių po skiepo teigė jautę 25–34 metų amžiaus asmenys, iš jų – 46,3 proc. vyrų. Mažiausiai nepageidaujamų reiškinių patyrė vyresni nei 65 metų asmenys. 3. Po pirmosios vakcinos nebuvo nė vienos ūminės alerginės reakcijos į skiepą, į gydymo įstaigą, dėl tam tikrų simptomų po skiepo pasireiškimo, kreipėsi 4,8 proc. asmenų. 4. Dažniausias simptomas – skausmas injekcijos vietoje, pasireiškė 94,4 proc. asmenų, jautusių nepageidaujamą poveikį.

The present study is an attempt to investigate the changes in serum cardiac troponin (cTn) and HighsensitivityC-reactive protein (HsCRP) markers levels in Iraqi ischemic heart disease (IHD) patientsincluding stable angina (SA), unstable angina (UA) and myocardial infarction (MI) compared to the healthycontrols (HC), and to evaluate the importance of the HsCRP between these diseases combination groupsfrom the dignostic point of view, in addition to find a significant correlation between HsCRP level and someIHD risk factors. The IHD’s mortality surpass that of every major disease, so it is important that to getsuch research especially among Iraqi patients. IHD is defined as blood flow reduction to the heart muscledue to build-up of fatty strips (plaque) in the coronary arteries, it exists when the coronary blood flowbecomes incapable of both delivering sufficient oxygen (O2) to the myocardium and taking away the carbondioxide (CO2) from the cells. Collecting the blood samples from one hundred thirty IHD patients (during theperiod from October 2020 to February 2021) with ages ranged (30-80) years, of both genders, investigatedfor HsCRP by enzyme linked immune sorbent assay (ELISA) technique and cardiac Troponin (cTn I) byimmunochromography method. This study observed that the HsCRP marker is a reliable diagnostic indicatorin both MI and UA groups (but not in SA patients), and in all diseases combination groups, and that therewas significant correlations between each of the triglyceride level and the hypertension, and the HsCRPmarker level, only in the MI group, but not in SA and UA patients.

Atherosclerosis is a serious disease that threatens the lives of both male and female. The risk of this diseaseincreases with age. In the current study, we attempted to estimate the most important indicators affected byheart disease, such as Hepcidin , iron, and sex hormones , 40 men and 20 women participated in this work,with age in range (45-75) years, all of them suffering from atherosclerosis . on the other hand, 15 healthymen and 15 healthy women participated as a control group The results have shown a significant change inthe level of Hepcidin among the patients compared to the control group. Additionally, the results of the studyalso proved that men with atherosclerosis suffer from a deficiency of the sexual hormone(testosterone).Remarkably , the present study has reported that patients with atherosclerosis are more susceptible tooxidative stress due to an increase in iron level on the other hand, men with atherosclerosis are more probableto have sexual dysfunction with age.
