Published: December 2022

Aim. To estimate the 10-year survival, clinical and biochemical status of responders and nonprogressors to cardiac resynchronization therapy (CRT) using biomarkers of fibrogenesis, neuro-humoral, immune, sympatho-adrenal activation.

Methods. Eighty CRT patients (mean age 58.9±10.1 years; 90% men; 72.5% with coronary artery disease) with the best CRT response timing («best» timing), assessed by maximum decrease in left ventricle end-systolic volume (LVESV), were divided into groups: Gr.1 (n=42): non-progressors (decrease in LVESV by >0<15%), Gr.2 (n=38): responders (decrease in LVESV by >15<30%). At baseline, in the «best» timing and in the «end» timing (November 2020), parameters of echocardiography, NT-proBNP, epinephrine, norepinephrine (NAdr), IL 1β, 6, TNF-α, C-reactive protein, matrix metalloproteinase 9, tissue inhibitor of matrix metalloproteinases 1 in plasma were studied. Survival was estimated by Kaplan-Meier method. Logistic regression was used to assess relationship of studied factors with CRT efficacy, and Cox regression with survival.

Results. In Gr.1, greater heart failure functional class was revealed (p=0.042). In Gr.1, there was less reverse cardiac remodeling in the «best» timing and greater pulmonary artery systolic pressure (p=0.029), NT-proBNP (p=0.020) in the «end» timing. Immune activation and imbalance of fibrogenesis were found across all time points of the study. In Gr.1, increase in NAdr level was revealed only in the «end» timing (p=0.017), but in Gr.2 it already was in the «best» timing (p=0.003). Correlations of NAdr «best» with ΔLVESV (r=-0.245; p=0.038), Δ left ventricle end-diastolic volume (LVEDV) (r=-0.293; p=0.013) in general group; and with IL-1β «best» (r=0.363; p=0.032), TNF-α «best» (r=0.360; p=0.034) in responders group were registered. Responder’s survival was the best only at 2 and 3 years after CRT implantation, with comparable survival between groups in subsequent years. In Gr.1, significant factors associated with 2-3-year survival were LVEDV «best» (RR 0.831 (0.713-0.967), p=0.017), LVESV «best» (RR 1.245 (1.040-1.492), p=0.017); in Gr.2, NT-proBNP «end» (RR 1.001 (1.000-1.001), p=0.024) related to 10-year survival in the absence of significant factors.

Conclusion. Comparable 10-year survival rate of non-progressors and responders is probably due to immune, sympathetic-adrenal activation, fibrogenesis imbalance. In non-progressors group CRT response can be assessed as positive due to significant reverse cardiac remodeling and survival comparable to responders and associated with NT-proBNP level.

Teacher Incentives and Attendance: Evidence from Tanzania
Authors: Schipper Youdi , Rodriguez-Segura Daniel
Published: December 2022

We study early grade teacher attendance in a nationally representative sample of public primary schools in Tanzania. We document high and costly levels of absence: during unannounced school visits, only 38 percent of teachers are observed to be actively teaching in the classroom. We find that an experimental incentive program that provided test-based performance rewards improved classroom attendance and teaching among eligible early grade teachers, although it did not explicitly incentivize attendance. Using panel regressions across the full sample, we find that teacher attendance is positively associated with the probability of school inspections and that classroom attendance and teaching activity is substantially higher among female teachers. Traditional incentives such as school infrastructure quality and salary level do not correlate with attendance.

THE INFLUENCE OF THE INJECTION TIMING ON THE PERFORMANCE OF TWO-STROKE OPPOSED-PISTON DIESEL ENGINE
Authors: KARPIŃSKI Paweł
Published: December 2022

The performance of the engine strongly depends on the parameters of the combustion process. In compression ignition engines, the fuel injection timing has a significant influence on this process. The moment of its occurrence and its duration should be chosen so that the maximum pressure value occurs several degrees after TDC. In order to analyze the effect of the fuel injection timing on the performance of the tested two-stroke opposed-piston diesel engine, a zero-dimensional model was developed in the AVL BOOST program. Next, a series of simulations were performed based on the defined calculation points for maximum continuous power, which resulted in power, specific fuel consumption and mean in-cylinder pressure. Finally, the engine map was made as a function of the start of combustion angle.
NOVEL TECHNIQUE OF CUSTOMIZING THE AUDIO FADE-OUT SHAPE
Authors: LUPŞA-TĂTARU Lucian
Published: December 2022

The fade-out sound effect designates a strict decreasing of the volume of an audio signal, starting from the detected initial level down to silence. Audio fade-outs are usually processed in off-line mode that is within audio editors, by employing different transcendental functions to set the time-related evolution of the audio level. However, the proliferation of mobile devices as well as the increasing popularity of web applications, implemented in HTML5/JavaScript, press for computing techniques suitable for real-time processing. In this context, having in view that the computation of the outputs of transcendental functions is very time-consuming, in order to construct the audio fade-out profile, a technique suitable for real-time computing is developed in the present investigation. The suggested technique is validated by means of an implementation in pure JavaScript, put forward with the purpose of immediate testing.

COMPARATIVE ANALYSIS OF THE IMPACT OF DIE DESIGN ON ITS LOAD AND DISTRIBUTION OF STRESS DURING EXTRUSION
Authors: NOWOTYŃSKA Irena , KUT Stanisław
Published: December 2022

In the paper a numerical comparative analysis of stresses in a steel die compressed by a ring during the extrusion process was presented. In the research, three design solutions of the die were used. The solutions vary depending on the quotient of the wall thickness of the die insert and the wall thickness of the compression ring while maintaining a constant tool diameter. The stresses occurring in the areas of the ring and the die were calculated depending on the design version of the tool and the pressure value. The analysis was carried out for the quotients of the die wall thickness to the ring wall thickness of 0.57, 1 and 1.75 and three press-in values of 0.004, 0.008 and 0.016 mm. The conducted research allowed determining the impact of the die design and assembly interference on the load bearing capacity. It was discovered that the use of a die insert with a smaller thickness compared to the thickness of the compression ring was the most advantageous from the point of view of the circumferential stresses.

IMPLEMENTING THE FADE-IN AUDIO EFFECT FOR REAL-TIME COMPUTING
Authors: LUPŞA-TĂTARU Lucian
Published: December 2022

Audio fading is performed in order to smoothly modify over time the level of an audio signal. In particular, the fade-in audio effect designates a gradually increase in the audio volume, starting from silence. In practice, audio fading is mostly carried out within audio editors i.e. in off-line mode by employing various transcendental functions to enforce the fade profile. Taking into account the increasing demand for interactive media services requiring real-time audio processing, the present approach advances an effective method of constructing the audio fade-in shape with a view to real-time computing. The paper encompasses plain and straightforward implementations in pure JavaScript, prepared precisely to validate the method of audio volume processing proposed here.

Now is the age of information technology. World is advancing day by day. At present in this progressing world communication from one place to another has become so easy, less costly, and faster. This modern life is almost impossible with the help of these communication technologies. People need to talk, need to share data, need to express their emotion from long distance. So they need to use technologies to communicate with one another. Nowadays the fields of MANET have yielded more and more popularity and thus MANET have become a subject of great interest for the researchers to enforce research activities. Mobile Ad Hoc Network (MANET) is the cooperative engagement of a collection of mobile nodes without the required intervention of any centralized access point or existing infrastructure. There is an increasing trend to adopt mobile ad hoc networking for commercial uses. Mobile Ad Hoc Network (MANET) is an emerging area of research to provide various communication services to the end users. But these communication services of Mobile Ad Hoc Network (MANET) use high capacity of bandwidth and a big amount of internet speed. Bandwidth optimization is indispensable in various communications for successful acceptance and deployment of such a technology. Thinking of this, I propose a New Bandwidth Optimization Technique that Enhance the Performance of Mobile Ad Hoc Network (MANET). The new Bandwidth optimization technique which is more efficient in terms of time delay in Mobile Ad Hoc Network (MANET) can redirect a new way towards optimization development in network communication and device junction technology.

Authors: ADEWUYI Saheed A. , AINA Segun , OLUWARANTI Adeniran I.
Published: December 2022

Electricity demand forecasting is a term used for prediction of users’ consumption on the grid ahead of actual demand. It is very important to all power stakeholders across levels. The power players employ electricity demand forecasting for sundry purposes. Moreover, the government’s policy on its market deregulation has greatly amplified its essence. Despite numerous studies on the subject using certain classical approaches, there exists an opportunity for exploration of more sophisticated methods such as the deep learning (DL) techniques. Successful researches about DL applications to com¬puter vision, speech recognition, and acoustic computing problems are motivation. However, such researches are not sufficiently exploited for electricity demand forecasting using DL methods. In this paper, we considered specific DL techniques (LSTM, CNN, and MLP) to short-term load fore¬casting problems, using tropical institutional data obtained from a Transmission Company. We also test how accurate are predictions across the techniques. Our results relatively revealed models appropriateness for the problem.

Published: December 2022

The rapid and uncontrollable cell division that spreads to surrounding tissues medically termed as malignant neoplasm, cancer is one of the most common diseases worldwide. The need for effective cancer treatment arises due to the increase in the number of cases and the anticipation of higher levels in the coming years. Oncolytic virotherapy is a promising technique that has shown encouraging results in several cases. Mathematical models of virotherapy have been widely developed, and one such model is the interaction between tumor cells and oncolytic virus. In this paper an artificially optimized Immune- Linear Quadratic Regulator (LQR) is introduced to improve the outcome of oncolytic virotherapy. The control strategy has been evaluated in silico on number of subjects. The crow search algorithm is used to tune immune and LQR parameters. The study is conducted on two subjects, S1 and S3, with LQR and Immune-LQR. The experimental results reveal a decrease in the number of tumor cells and remain in the treatment area from day ten onwards, this indicates the robustness of treatment strategies that can achieve tumor reduction regardless of the uncertainty in the biological parameters.

The Sliding Mode Controllers (SMCs) are considered among the most common stabilizer and controllers used with robotic systems due to their robust nonlinear scheme designed to control nonlinear systems. SMCs are insensitive to external disturbance and system parameters variations. Although the SMC is an adaptive and model-based controller, some of its values need to be determined precisely. In this paper, an Optimal Sliding Mode Controller (OSMC) is suggested based on Whale Optimization Algorithm (WOA) to control a two-link lower limb rehabilitation robot. This controller has two parts, the equivalent part, and the supervisory controller part. The stability assurance of the controlled rehabilitation robot is analyzed based on Lyapunov stability. The WO algorithm is used to determine optimal parameters for the suggested SMC. Simulation results of two tested trajectories (linear step signal and nonlinear sine signal) demonstrate the effectiveness of the suggested OSMC with fast response, very small overshoot, and minimum steady-state error.

Stuttering is a speech impediment that is a very complex disorder. It is difficult to diagnose and treat, and is of unknown initiation, despite the large number of studies in this field. Stuttering can take many forms and varies from person to person, and it can change under the influence of external factors. Diagnosing and treating speech disorders such as stuttering requires from a speech therapist, not only good profes-sional preparation, but also experience gained through research and practice in the field. The use of acoustic methods in combination with elements of artificial intelligence makes it possible to objectively assess the disorder, as well as to control the effects of treatment. The main aim of the study was to present an algorithm for automatic recognition of fillers disfluency in the statements of people who stutter. This is done on the basis of their parameterized features in the amplitude-frequency space. The work provides as well, exemplary results demonstrating their possibility and effectiveness. In order to verify and optimize the procedures, the statements of seven stutterers with duration of 2 to 4 minutes were selected. Over 70% efficiency and predictability of automatic detection of these disfluencies was achieved. The use of an automatic method in conjunction with therapy for a stuttering person can give us the opportunity to objectively assess the disorder, as well as to evaluate the progress of therapy.

Published: December 2022

Introduction: Tailgut cysts are rare congenital entity that arises from the embryological hindgut and
usually located in presacral space. Here we report a case of tail gut cyst which is an infrequent condition.
Case report: Here, we report a nineteen year old male with lower abdominal pain. The relevant investigations were performed.
The CT abdomen revealed a well-dened cystic lesion in the pelvis in lower presacral region and posterior to rectum with small
calcied foci suggestive of tail gut cyst with scalloping of sacrum. MRI pelvis suggested large well dened unilocular cystic
lesion in the retro-rectal and pre-sacral region extending from S2 to mid coccygeal level showing thin imperceptible walls few
tiny projections and small rounded non enhancing nodule along its posterior wall with thin focal calcication seen in its wall
with no evidence of malignancy and no signs of osseous destruction. The patient was explored and intraoperatively ndings
revealed a cyst of size 8 cm * 5 cm behind the rectum and in front of sacrum which was densely adhered to the posterior wall of
rectum but free from sacrum. The mass was resected as a whole and sent for histopathological exam which was suggestive of
tailgut cyst. Tailgut cysts is infrequent condition which manifests as chronic lower abdominal pai Conclusion: n. It is crucial that
such entity be diagnosed and surgically excised early in its presentation. It is important to rule out malignancy in the post
operative biopsy

Background: One of the most prevalent abdominal crises is acute appendicitis. Many efforts have been
directed towards early diagnosis and intervention. Delay in diagnosis leads to increase morbidity and
costs. Present study was aimed to evaluate the correlation of CRP and PCT with perioperative ndings in suspected cases of
acute appendicitis and to nd whether they can aid in the diagnosis of acute appendicitis. Material and Methods: Present
study was hospital based screening test study, conducted patients of age > 18 years, either gender, who presented with right
iliac fossa pain lasting < 48 hours and were tentatively diagnosed with acute appendicitis, underwent surgery. Results: Among
115 patients with acute appendicitis, most of patients belong to age group of 21 to 30 years (45.2 %) followed by 31 to 40 and 10 to
20 years (18.3 %). Out of 115 patients 40 (34.8%) patients were females and 75 (65.2%) patients were males. CRP was positive in
84 (73.04%) and procalcitonin was positive in 66 (57.39%) patients with acute appendicitis. CRP had a sensitivity of 72.82%, a
specicity of 25%, a positive predictive value of 89.29%, and a negative predictive value of 9.68 %. Procalcitonin had a sensitivity
of 57.28 %, a specicity of 41.67 %, a positive predictive value of 89.39 %, and a negative predictive value of 10.20%.
Conclusion: Elevation in CRP as well as procalcitonin levels only cannot be used for nal diagnosis of acute appendicitis, but it
can act as an adjunct when evaluating the available clinical and laboratory
