This paper examines the effects of current and conductance noises in a minimal Hodgkin–Huxley type model of a cold receptor neuron. Current noise enters the membrane equation directly while conductance noise is propagated through the activation variables. Compared with common used interspike interval method, ISI-distance is a simple complementary approach to measure the different effects of current and conductance noises. ISI-distance extracts information from the interspike intervals by evaluating the ratio of instantaneous firing rates, which is parameter-free, time scale-independent and easy to visualize. Simulation results show that the most significant differences between different noise implementations in a pacemaker-like tonic firing regime at the transition to chaotic burst discharges.

The COVID-19 pandemic has impacted all sectors of human life globally, including the world of education. The world of education is forced to adapt by implementing a distance learning system to limit the mobility of educators and students. Program Studi D4 Penyajian Musik ISI Yogyakarta is one of the educational institutions that conduct distance learning. As a vocational education institution, ISI Yogyakarta helds many music practice courses to support its students' skills. This research aims to determine the benefits, drawbacks, and challenges of the distance learning system in music practice courses. This research is a qualitative study with 2 methods of data collection, namely in-depth interviews and questionnaires. Questionnaires were distributed to the respondents which are active students of the Prodi D4 Penyajian Musik, ISI Yogyakarta and will be confirmed by the results of in-depth interviews with the subject lecturers. The research results were formulated using the Miles & Huberman concept, namely: (1) data reduction; (2) data presentation; and (3) drawing conclusions (Miles & Huberman, 1984). The results of the study are concluding sentences about the benefits, drawbacks, and challenges of the distance learning method. These conclusions will be the basis for developing recommendations for the most effective distance learning process for the form of music practice lectures.

We study the discrimination capability of spike time sequences using the Chernoff distance as a metric. We assume that spike sequences are generated by renewal processes and study how the Chernoff distance depends on the shape of interspike interval (ISI) distribution. First, we consider a lower bound to the Chernoff distance because it has a simple closed form. Then we consider specific models of ISI distributions such as the gamma, inverse gaussian (IG), exponential with refractory period (ER), and that of the leaky integrate-and-fire (LIF) neuron. We found that the discrimination capability of spike times strongly depends on high-order moments of ISI and that it is higher when the spike time sequence has a larger skewness and a smaller kurtosis. High variability in terms of coefficient of variation (CV) does not necessarily mean that the spike times have less discrimination capability. Spike sequences generated by the gamma distribution have the minimum discrimination capability for a given mean and variance of ISI. We used series expansions to calculate the mean and variance of ISIs for LIF neurons as a function of the mean input level and the input noise variance. Spike sequences from an LIF neuron are more capable of discrimination than those of IG and gamma distributions when the stationary voltage level is close to the neuron's threshold value of the neuron.

Abstract Purpose To analyze whether preoperative patellofemoral anatomy is associated with clinical improvement and failure rate after isolated patellofemoral arthroplasty (PFA) using a modern inlay-type trochlear implant. Methods Prospectively collected 24 months data of patients treated with isolated inlay PFA (HemiCAP® Wave, Arthrosurface, Franklin, MA, USA) between 2009 and 2016, and available digitalized preoperative imaging (plain radiographs in three planes and MRI) were retrospectively analyzed. All patients were evaluated using the WOMAC score, Lysholm score, and VAS pain. Patients revised to TKA or not achieving the minimal clinically important difference (MCID) for the total WOMAC score or VAS pain were considered failures. Preoperative imaging was analyzed regarding the following aspects: Tibiofemoral OA, patellofemoral OA, trochlear dysplasia (Dejour classification), patellar height (Insall–Salvati index [ISI]; Patellotrochlear index [PTI]), and position of the tibial tuberosity (TT–TG and TT–PCL distance). Results A total of 41 patients (61% female) with a mean age of 48 ± 13 years could be included. Fifteen patients (37%) were considered failures, with 5 patients (12%) revised to TKA and 10 patients (24%) not achieving MCID for WOMAC total or VAS pain. Failures had a significantly higher ISI, and a significantly lower PTI. Furthermore, the proportion of patients with a pathologic ISI (> 1.2), a pathologic PTI (< 0.28), and without trochlear dysplasia were significantly higher in failures. Significantly greater improvements in clinical outcome scores were observed in patients with a higher preoperative grade of patellofemoral OA, ISI ≤ 1.2, PTI ≥ 0.28, TT–PCL distance ≤ 21 mm, and a dysplastic trochlea. Conclusion Preoperative patellofemoral anatomy is significantly associated with clinical improvement and failure rate after isolated inlay PFA. Less improvement and a higher failure rate must be expected in patients with patella alta (ISI > 1.2 and PTI < 0.28), absence of trochlear dysplasia, and a lateralized position of the tibial tuberosity (TT–PCL distance > 21 mm). Concomitant procedures such as tibial tuberosity transfer may, therefore, be considered in such patients. Level of evidence Level III, retrospective analysis of prospectively collected data.

Techniques for recording large-scale neuronal spiking activity are developing very fast. This leads to an increasing demand for algorithms capable of analyzing large amounts of experimental spike train data. One of the most crucial and demanding tasks is the identification of similarity patterns with a very high temporal resolution and across different spatial scales. To address this task, in recent years three time-resolved measures of spike train synchrony have been proposed, the ISI-distance, the SPIKE-distance, and event synchronization. The Matlab source codes for calculating and visualizing these measures have been made publicly available. However, due to the many different possible representations of the results the use of these codes is rather complicated and their application requires some basic knowledge of Matlab. Thus it became desirable to provide a more user-friendly and interactive interface. Here we address this need and present SPIKY, a graphical user interface that facilitates the application of time-resolved measures of spike train synchrony to both simulated and real data. SPIKY includes implementations of the ISI-distance, the SPIKE-distance, and the SPIKE-synchronization (an improved and simplified extension of event synchronization) that have been optimized with respect to computation speed and memory demand. It also comprises a spike train generator and an event detector that makes it capable of analyzing continuous data. Finally, the SPIKY package includes additional complementary programs aimed at the analysis of large numbers of datasets and the estimation of significance levels.

Abstract Introduction: Insomnia is a significant co-morbidity for cancer survivors, and can independently reduce lifespan, but there is currently no objective biochemical measure of insomnia. Circadian rhythms are 24 hour cycles that control physiologic processes including sleep. Disrupted circadian rhythms have been proposed as a cause of insomnia. Here, we describe the use of a novel biomarker, BloodCCD, to assess circadian rhythms from RNA-sequencing of blood samples from two independent clinical trials and one observational study. BloodCCD was adapted from Clock Correlation Distance (CCD), which assesses normal progression of the molecular circadian clock from gene expression in tissue samples. We used BloodCCD to interrogate whether 1) cancer patients and survivors with insomnia have disrupted circadian rhythms compared to healthy good sleepers, and 2) whether the degree of circadian disruption correlates with severity of insomnia in survivors. Methods: For BloodCCD analysis, time-series RNA-sequencing of human blood from healthy subjects were used to construct a reference correlation matrix of 42 genes which oscillate with 24-hour rhythms. To assess the Aims, RNA-sequencing from patient and survivor blood samples were compared to this reference correlation matrix to generate a BloodCCD score. A higher score indicates a further distance from a healthy clock, and thus clock disruption. For the first Aim, blood RNA-sequencing from cancer patients undergoing active treatment and survivors at least 2-months post-treatment and with insomnia were compared to healthy good sleepers. For the second Aim, blood RNA-sequencing from cancer survivors with insomnia were assessed, stratified by Insomnia Severity Index (ISI) Score into mild (ISI 10-14), moderate (ISI 15-21), and severe (ISI 22-28) insomnia. Results: Patients (n=28, 100% prostate cancer) and cancer survivors (n=497, ~72% breast cancer) had higher BloodCCD scores, indicating disrupted circadian clock, compared to healthy good sleepers (n=14), with scores of 9.98, 7.99, and 4.13, respectively. When cancer survivors were stratified by insomnia severity, those with severe insomnia (ISI 22-28) had the highest BloodCCD, 9.00, while those with moderate insomnia (ISI 15-21) had a score of 8.24 and those with mild insomnia (ISI 10-14) had the lowest score of 7.93, indicating that survivors with severe insomnia had a more disrupted circadian clock. All BloodCCD values were p < 0.001 for each value compared to reference correlation. Conclusions: BloodCCD shows promise as a biomarker to biochemically detect disrupted circadian rhythms in cancer patients and survivors, and as a readout for insomnia severity. Future studies should investigate whether BloodCCD improves in cancer survivors receiving interventions for insomnia.

Full textAbstract:
This paper discusses the enhancement of the wireless rake receiver for high speed and short distance indoor ultra wideband (UWB) propagation with line-of sight (LOS) and non line-of sight (NLOS) channel models. The proposed matched rake receiver uses three main combining techniques, maximum ratio combining (MRC), equal gain combining (EGC), and selective combining (SC) to capture most of the energy of the multi-path components (MPCs). When the wireless communication systems work with high capacity and high speed in transmission and reception scenarios, there will be a serious challenge defined as inter-symbol interference (ISI) during the reception process. The ISI causes increasing in the bit error rate (BER) when the wireless communication systems work with high bit rate propagation. The matched rake receiver scheme was designed to suppress ISI by maximizing the signal to noise ratio (SNR) before constructing the desired signal in decision circuit and effectively the system enhancement is improved. After adding additive white Gaussian noise (AWGN) to the received signal, the improvement is cleared comparing with the theoretical results that has no AWGN. During the comparison of the simulation results, MRC partial rake receiver of less complexity showed better performance than the EGC and SC rake receivers.

Fiber optic has characteristics for optical transmission system. One of optical characteristics is pulse broadening, known as dispersion. The dispersion is a condition where pulse in output side is larger than pulse in input side. It means that pulse broadening had happened. In the communication system, it’s known as inter symbol interference (ISI). Effect of Inter symbol interference increasing the error bit or BER value. In optical communication system, dispersion is most influence to the data rate that fiber can support. Besides, bandwidth, information capacity, transmission distance, wavelength and fiber type can also influenced by the dispersion.

Full textAbstract:
Using a single photon avalanche diode (SPAD) as a receiver in an optical wireless communications (OWC) system can effectively expand the transmission distance. However, the performance of the SPAD receiver is usually affected with the bit error rate (BER) lower bound determined by background light and the inter-symbol interference (ISI) distortion caused by dead time. In this paper, external time-gated technology is employed, and the SPAD is only activated within the set gate-ON time to alleviate the influence of background light and ISI distortion. The SPAD photon counting model and the communication BER model are established according to the external time-gated characteristics. Considering the functional relationship among the gate-ON time, signal light flux, background light flux and blocking time, we take the minimum BER as the optimization target, the optimal gate-ON time is derived. The numerical results show that whenever the signal light flux or the background light flux is higher, the BER performance of the time-gated mode is apparently better than the free-running mode. For example, when signal photons and background photons are 30 and 10 per symbol time, respectively, the BER of free-running SPAD converges to 0.1, while the BER of the time-gated scheme is about 10−6.

<span lang="EN-US">Visible Light Communication (VLC) has become an accolade to its radio frequency counterpart. In VLC system, orthogonal frequency division multiplexing (OFDM) has drawn much attention, because of simple equalization, high spectral efficiency, high data rate and robustness to intersymbol interference (ISI). Besides, there are emerging applications that ought to be gotten with low latency and high reliability. To diminish power requirements with no transmission capacity extension, Trellis coded modulation (TCM) is utilized as a part of the framework in which the free distance of trellis diagram is equivalent to the minimum distance between the points of constellation focuses in partitioned subsets, which augments the coding gain up i.e. the performance parameter viably. TCM together with VLC-OFDM enhances the transmission execution in reasonable frameworks. In this paper, we propose OFDM which is based on TCM and is planned and exeuted for digitized OFDM frameworks by presenting delta sigma modulation (DSM) considering VLC channel. Simulation results show that the proposed TCM based VLC-OFDM offers incredible robustness against noises and nonlinear degradation.</span>

Full textAbstract:
Bit-patterned media recording (BPMR) is proposed as a candidate for future magnetic data storage to overcome superparamagnetism. The distance between magnetic islands in BPMR must be reduced to increase the areal density (AD). As magnetic islands become closer, two-dimensional (2D) interference is increased, including intersymbol interference (ISI) based on the down-track direction and intertrack interference (ITI) from the cross-track direction. We propose an estimator to predict interference from neighboring (upper and lower) tracks. This estimator exploits the 2D Viterbi algorithm (VA) with reduced states. We removed the interference from the neighboring track and applied a simple 1D VA to detect the received signal. The simulation results show that our model performs better than previously proposed models.

The trend of high-speed optical communication is to realize large capacity, fast speed and long haul transmission. However, the dispersion in an optical fiber link can cause signals distortion or even inter symbol interference (ISI). With increasing signal rate and transmission distance in the optical communication system, the development of high-speed optical fiber communication is restricted seriously. This paper is focusing on the dispersion characteristics and compensation of the polarization multiplexing (POLMUX) coherent optical communication system: (i) to study on dispersion theoretically, e.g., chromatic dispersion (CD), polarization mode dispersion (PMD) and dispersion tolerance; (ii) to analyze and compare the performance of dispersion with various 16-ary modulation formats; (iii) to compensate dispersion by the classical dispersion compensation methods.

<span>A hybrid optical CDMA-DWDM system accommodating 12 optical CDMA users carried by 5 DWDM wavelengths at a data rate of 60Gb/s/wavelength with channel spacing of 0.4nm is implemented under the effect of four-wave mixing (FWM). It was found that the FWM effect could be minimized by the use of CDMA technology, where the energy of each bit is spread over the optical sequence code. Over a distance of 105.075km, significant performance of all optical CDMA users in terms of the BER is achieved. The results reveal that the inter-symbol interference (ISI) can be mitigated when the interval of optical signature sequence code is squeezed into 25% of the bit duration. </span>

Full textAbstract:
Walking performance of persons with multiple sclerosis (MS) is strongly influenced by the activation signals received by lower leg muscles. We examined the associations between force steadiness and motor unit discharge characteristics of lower leg muscles during submaximal isometric contractions with tests of walking performance and disability status in individuals who self-reported walking difficulties due to MS. We expected that worse walking performance would be associated with weaker plantar flexor muscles, worse force steadiness, and slower motor unit discharge times. Twenty-three individuals with relapsing-remitting MS (56 ± 7 yr) participated in the study. Participants completed one to three evaluation sessions that involved two walking tests (25-ft walk and 6-min walk), a manual dexterity test (grooved pegboard), health-related questionnaires, and measurement of strength, force steadiness, and motor unit discharge characteristics of lower leg muscles. Multiple regression analyses were used to construct models to explain the variance in measures of walking performance. There were statistically significant differences (effect sizes: 0.21–0.60) between the three muscles in mean interspike interval (ISI) and ISI distributions during steady submaximal contractions with the plantar flexor and dorsiflexor muscles. The regression models explained 40% of the variance in 6-min walk distance and 47% of the variance in 25-ft walk time with two or three variables that included mean ISI for one of the plantar flexor muscles, dorsiflexor strength, and force steadiness. Walking speed and endurance in persons with relapsing-remitting MS were reduced in individuals with longer ISIs, weaker dorsiflexors, and worse plantar flexor force steadiness.NEW & NOTEWORTHY The walking endurance and gait speed of persons with relapsing-remitting multiple sclerosis (MS) were worse in individuals who had weaker dorsiflexor muscles and greater force fluctuations and longer times between action potentials discharged by motor units in plantar flexor muscles during steady isometric contractions.

Pada perguruan tinggi, kasus plagiarisme menjadi satu hal yang paling disoroti khususnya pada kasus publikasi karya ilmiah. Di lingkungan perguruan tinggi, pencegahan terhadap kasus plagiarisme sudah dilakukan dengan melampirkan halaman surat pernyataan anti plagiarisme pada laporan karya ilmiah. Namun tindakan ini belum cukup menjamin tingkat originalitas suatu karya. Cara lain untuk mencegah tindakan plagiarisme adalah dengan mendeteksi adanya kemiripan dokumen sebelum dokumen tersebut diakui pihak kedua. Penelitian ini merancang dan membangun sistem untuk deteksi kemiripan isi teks dokumen pada jurnal publikasi skripsi karya mahasiswa dengan menggunakan metodeLevenshtein Distance dan Cosine Similarity. Aplikasi ini berbasis website dengan keluaran sistem berupa hasil prosentase kemiripan dokumen yang diunggah, yang mana akan ditampilkan dalam sebuah file lampiran pernyataan. File lampiran ini yang nantinya dapat dicetak dan digunakan sebagai surat jaminan originalitas karya ilmiah menggantikan surat pernyataan anti plagiarisme yang digunakan sebelumnya.

Inter symbol interference (ISI) caused by dispersion in optical fibers is the major limiting factor on the achievable data rate or transmission distance in high-speed fiber-optic interconnects1. Compared with optical-domain and other electrical-domain dispersion compensation methods, duobinary coding technology is used due to its higher spectral efficiency. In this paper, a monolithically integrated duobinary optical transmitter has be designed and fabricated in standard 0.18 μm CMOS technology. This transmitter consists of a duobinary encoder and a VCSEL driver. The master-slave D flip-flop structure is used to generate the wideband one bit delay which is important for the realization of duobinary signal. An open drain structure is used in VCSEL driver design to provide the higher current output in low supply voltage condition. This duobinary transmitter can operate up to 5 Gb/s with 20 mA current output. The current consumption is only 50 mA under 1.8 V supply voltage.

Full textAbstract:
Olfactory bulb plays an important part in signal encoding of olfactory system. The interaction between excitatory mitral cell (MC) and inhibitory granule cell (GC) is particularly crucial. In this paper, the current situation of synchronous oscillation in the network of olfactory system is firstly introduced. Then we set up a dynamical model of MC and GC in the olfactory bulb. The simulation shows the firing patterns of single MC and single GC, as well as these two kinds of cells having a coupling relationship. The results indicate that MCs have an excitatory effect on GCs, and GCs have an inhibitory effect on MCs. The firing pattern varies with different synaptic strength. In addition, we set up simple olfactory network models, discussing the influence of ring-like and grid-like neuronal networks of GCs on the synchronization of two MCs. Different types of firing synchronization are quantified by means of ISI-distance method. The numerical analysis indicates that grid-like neuronal network can make MCs synchronize better.

Full textAbstract:
Background: The etiology for recurrent patellar dislocations in children with patellofemoral instability (PFI) is not always apparent. Radiographic and other imaging measures help guide the clinician. However, the imaging parameters for pathologic pediatric PFI and the significance of these measures based on severity are not clearly defined. This study compares common imaging measures for PFI in a non-pathologic and known patellar dislocation pediatric population and determines the likelihood of symptoms based on the severity of each individual measure. Methods: An IRB-approved retrospective review of knee MRIs and radiographs at a single pediatric institution identified 108 limbs (102 patients) meeting inclusion criteria. Sixty-nine limbs had no known patellar pathology (control group) and 39 had surgery for recurrent patellar dislocations (surgical group). MRI measures included tibial tuberosity-trochlear groove distance (TT-TG), tibial tuberosity-posterior cruciate ligament distance (TT-PCL), and lateral trochlear inclination (LTI). Radiographic measures included the Caton-Deschamps Index (CDI) and Insall-Salvati Index (ISI). These measures are representative of PFI risk factors, specifically patellar tendon malalignment, trochlear dysplasia, and patella alta. Binomial logistic regression was used to relate the anatomical parameters to the probability of PFI. Results: The surgical and control groups were similar in terms of age, height and weight. The logistic regression analysis indicated that the TT-TG (p=0.001) and LTI (p<0.001) were correlated with PFI. The odds ratio (95% confidence interval) was 1.19 (1.07 -1.31) for TT-TG, giving the increased probability of a knee to experience PFI for each 1 mm increase. The odds ratio was 0.85 (0.77-0.93) for LTI, showing a decrease in the probability of instability with each 1° increase. Neither CDI nor ISI measures significantly correlated with probability of PFI (p=0.30 and p=0.18, respectively). The two parameters of TT-TG and LTI accounted for 42% (Nagelkerke R2) of the variance between the control and surgical groups. Conclusion/Significance: Comparing pediatric patients with recurrent patellar dislocations to controls, logistic regression analysis suggests the likelihood of PFI correlates with the severity of specific radiographic measures, specifically those representing the degree of patellar tendon alignment (TT-TG) and trochlear dysplasia (LTI). Knowing this correlation can help guide the treatment of PFI in pediatric patients by providing physicians and families with a continuum on which to base their decisions.

The aim of this study is to investigate empirically the factors that determine the level of automobile trade in East Asian countries by taking into account government policies as well as the role of MNEs. To do so, in this study we include dummies of import substitution industrialisation (ISI) and export orientation industrialisation (EOI) policies as well as Japanese FDI as additional explanatory variables in our augmented gravity models. We found that GDPs, distance, per capita income, FTA, government policies, language and FDI are the determinants for the development of automobile industry in each country in East Asia. In the case of auto P&C, apart from economic size, the role of government through trade policy (i.e., FTA) and industrial policies as well as the role of MNCs are the major contributors to the development both exports and imports of East Asian countries. In the case of final automobiles, the role of FTA and language seems to be unimportant. Nonetheless, the role of government policies and MNCs seem to be important.

Full textAbstract:
Recently, unmanned aerial vehicles (UAVs) have been widely used in various industries. However, the communication links of UAVs are also threatened by eavesdropping. To enhance physical layer security (PLS) for UAV communications, a time-division multiarray beamforming (TDMB) scheme is proposed. Multiple antenna arrays steer their beamforming vectors based on their position relative to the legitimate user (LU). Thus, angle-distance-dependent directional modulation (DM) can be achieved. Time-division means multiple antenna arrays take turns transmitting different symbols from a same packet. The receiver in undesired directions suffers from intersymbol interference (ISI) because of the path differences between the receiver and different antenna arrays. This paper shows the signal-to-interference-plus-noise ratio (SINR) distribution with the proposed method in a 2-dimensional plane. Also, the improvement of the secrecy rate with the proposed method under different total antennas and artificial noise power is studied. Overall, these results indicate that the security rate has improved more with the proposed method, where the numbers of antennas and the power of AN are limited. Therefore, this method is suitable for UAV security communication.

Full textAbstract:
Wireless communication is one of the speedily evolving and dynamic technology areas in the realm of communication. OFDM is an acronym for Orthogonal Frequency Division Multiplexing. It is a version of FDM in which orthogonal subcarriers are closely spaced to maximize bandwidth consumption. By decreasing Inter Symbol Interference (ISI) and increasing the Signal-to-Noise ratio (SNR), it has enhanced the quality of long-distance communication. It’s commonly employed in digital communication systems to safeguard digital data from noise and interference while also reducing bit mistakes. Convolutional codes, Block codes, are the two fundamental forms of channel codes. Block codes are based on abstract algebra and finite field arithmetic. They are capable of detecting and correcting faults. This category includes LDPC and Reed Solomon codes. Convolution codes, alternatively are created using a distinct strong mathematical framework and are generally utilised for real-time error correction. They combine all of the data into a single codeword. Reed-Solomon codes are block-based error correcting codes used in digital communications, storage, and ADSL, among other uses. The BER performance of an OFDM system is investigated in this paper using various channel coding algorithms.

Full textAbstract:
This article investigates the technical efficiency in German higher education while accounting for possible heterogeneity in the production technology. We investigate whether a latent class model would identify the different sub-disciplines of life sciences in a sample of biology and agricultural units based on technological differences. We fit a latent class stochastic frontier model to estimate the parameters of an output distance function formulation of the production technology to investigate if a technological separation is meaningful along sub-disciplinary lines. We apply bootstrapping techniques for model validation. Our analysis relies on evaluating a unique dataset that matches information on higher educational institutions provided by the Federal Statistical Office of Germany with the bibliometric information extracted from the ISI Web of Science Database. The estimates indicate that neglecting to account for the possible existence of latent classes leads to a biased perception of efficiency. A classification into a research-focused and teaching-focused decision-making unit improves model fit compared to the pooled stochastic frontier model. Additionally, research-focused units have a higher median technical efficiency than teaching-focused units. As the research focus is more prevalent in the biology subsample an analysis not considering the potential existence of latent classes might misleadingly give the appearance of a higher mean efficiency of biology. In fact, we find no evidence of a difference in the mean technical efficiencies for German agricultural sciences and biology using the latent class model.

Odia character is a usually handwritten, which was generally occupied by scanner into machine readable form. In this regard several recognition technique have been evolved for variance kind of languages but writing pattern of odia character is just like as curve appearance; Hence it is more difficult for recognition. In this article we have presented the novel approach for Odia character recognition based on the different angle based symmetric axis feature extraction technique which gives high accuracy of recognition pattern. This empirical model generates a unique angle based boundary points on every skeletonised character images. These points are interconnected with each other in order to extract row and column symmetry axis. We extracted feature matrix having mean distance of row, mean angle of row, mean distance of column and mean angle of column from centre of the image to midpoint of the symmetric axis respectively. The system uses a 10 fold validation to the random forest (RF) classifier and SVM for feature matrix. We have considered the standard database on 200 images having each of 47 Odia character and 10 Odia numeric for simulation. As we have noted outcome of simulation of SVM and RF yields 96.3% and 98.2% accuracy rate on NIT Rourkela Odia character database and 88.9% and 93.6% from ISI Kolkata Odia numerical database.</span>

Full textAbstract:
As synchronized activity is associated with basic brain functions and pathological states, spike train synchrony has become an important measure to analyze experimental neuronal data. Many measures of spike train synchrony have been proposed, but there is no gold standard allowing for comparison of results from different experiments. This work aims to provide guidance on which synchrony measure is best suited to quantify the effect of epileptiform-inducing substances (e.g., bicuculline, BIC) in in vitro neuronal spike train data. Spike train data from recordings are likely to suffer from erroneous spike detection, such as missed spikes (false negative) or noise (false positive). Therefore, different timescale-dependent (cross-correlation, mutual information, spike time tiling coefficient) and timescale-independent (Spike-contrast, phase synchronization (PS), A-SPIKE-synchronization, A-ISI-distance, ARI-SPIKE-distance) synchrony measures were compared in terms of their robustness to erroneous spike trains. For this purpose, erroneous spike trains were generated by randomly adding (false positive) or deleting (false negative) spikes (in silico manipulated data) from experimental data. In addition, experimental data were analyzed using different spike detection threshold factors in order to confirm the robustness of the synchrony measures. All experimental data were recorded from cortical neuronal networks on microelectrode array chips, which show epileptiform activity induced by the substance BIC. As a result of the in silico manipulated data, Spike-contrast was the only measure that was robust to false-negative as well as false-positive spikes. Analyzing the experimental data set revealed that all measures were able to capture the effect of BIC in a statistically significant way, with Spike-contrast showing the highest statistical significance even at low spike detection thresholds. In summary, we suggest using Spike-contrast to complement established synchrony measures because it is timescale independent and robust to erroneous spike trains.

Background: Osteopathic manual procedures called pump techniques include thoracic, abdominal, and pedal pumps. Similar techniques, called pompages, are also addressed to joints and muscles. Despite their widespread use, no systematic review has been published on their effectiveness. (2) Methods: CINAHL, Cochrane Controlled Trials Register, ISI Web of Science, PEDro, PubMed, and Scopus databases were searched until July 2020. Randomized Controlled Trials (RCTs) on adults were included. Subjective (e.g., pain, physical function) and objective (e.g., pulmonary function, blood collection) outcomes were considered. The Risk of Bias tool (RoB 2) and the GRADE instrument were used to evaluate the quality of evidence. (3) Results: 25 RCTs were included: 20 concerning the pump techniques and five concerning pompages. Due to the extensive heterogeneity of such studies, it was not possible to perform a meta-analysis. The risk of bias resulted from moderate to high and the quality of the evidence was from very low to high. Singular studies suggested some effectiveness of pump techniques on pain and length of hospitalization. Pompage seems also to help improve walking distance and balance. (4) Conclusions: Although several studies have been published on manual pump techniques, the differences for population, modalities, dosage, and outcome measures do not allow definite conclusions of their effectiveness.

Full textAbstract:
This paper presents a rolling shutter orthogonal frequency-division multiplexing (RS-OFDM) optical camera communication higher rate longer range proposed in IEEE 802.15.7a Task Group (TG7a) using an image sensor as a receiver. OFDM is a digital multi-carrier modulation scheme deployed for broadband wireless communication to resolve the inter-symbol interference (ISI) effect caused by the multipath channel. In optical wireless communication systems, OFDM was applied widely for indoor applications: internet of things, e-health, vehicular, and localization systems. The mobility scenario is a big problem for OWC systems, which reduces the system performance due to the optical channel variation in the processing time. In addition to that, signal detection should be considered in the mobility environment to improve the signal-to-noise ratio of OWC systems. In this paper, we proposed the convolution neural network (CNN) for LED detection in the RS-OFDM system, considering the mobility effect. In addition to that, the deep neural network was applied to detect the start of OFDM frame instead of conventional technology (Van De Beek algorithm). By applying our approach, the RS-OFDM system can achieve long communication (18 m distance) with a low error rate in the 2 m/s velocity environment.

Full textAbstract:
It is well known that, typically, saccadic eye movements precede goal-directed hand movements to a visual target stimulus. Also pointing in general is more accurate when the pointing target is gazed at. In this study, it is hypothesized that saccades are not only preceding pointing but that gaze also is stabilized during pointing in humans. Subjects, whose eye and pointing movements were recorded, had to make a hand movement and a saccade to a first target. At arm movement peak velocity, when the eyes are usually already fixating the first target, a new target appeared, and subjects had to make a saccade toward it ( dynamical trial type). In the statical trial type, a new target was offered when pointing was just completed. In a control experiment, a sequence of two saccades had to be made, with two different interstimulus intervals (ISI), comparable with the ISIs found in the first experiment for dynamic and static trial types. In a third experiment, ocular fixation position and pointing target were dissociated, subjects pointed at not fixated targets. The results showed that latencies of saccades toward the second target were on average 155 ms longer in the dynamic trial types, compared with the static trial types. Saccades evoked during pointing appeared to be delayed with approximately the remaining deceleration time of the pointing movement, resulting in “normal” residual saccadic reaction times (RTs), measured from pointing movement offset to saccade movement onset. In the control experiment, the latency of the second saccade was on average only 29 ms larger when the two targets appeared with a short ISI compared with trials with long ISIs. Therefore the saccadic refractory period cannot be responsible for the substantially bigger delays that were found in the first experiment. The observed saccadic delay during pointing is modulated by the distance between ocular fixation position and pointing target. The largest delays were found when the targets coincided, the smallest delays when they were dissociated. In sum, our results provide evidence for an active saccadic inhibition process, presumably to keep steady ocular fixation at a pointing target and its surroundings. Possible neurophysiological substrates that might underlie the reported phenomena are discussed.

Full textAbstract:
We explore the feasibility of Terrestrial Broadcasting in a Single-Frequency Network (SFN) with standard 5G New Radio (5GNR) numerology designed for uni-cast transmission. Instead of the classical OFDM symbol-by-symbol detector scheme or a more complex equalization technique, we designed a Recurrent-Neural-Network (RNN)-based detector that replaces the channel estimation and equalization blocks. The RNN is a bidirectional Long Short-Term Memory (bi-LSTM) that computes the log-likelihood ratios delivered to the LDPC decoder starting from the received symbols affected by strong intersymbol/intercarrier interference (ISI/ICI) on time-varying channels. To simplify the RNN receiver and reduce the system overhead, pilot and data signals in our proposed scheme are superimposed instead of interspersed. We describe the parameter optimization of the RNN and provide end-to-end simulation results, comparing them with those of a classical system, where the OFDM waveform is specifically designed for Terrestrial Broadcasting. We show that the system outperforms classical receivers, especially in challenging scenarios associated with large intersite distance and large mobility. We also provide evidence of the robustness of the designed RNN receiver, showing that an RNN receiver trained on a single signal-to-noise ratio and user velocity performs efficiently also in a large range of scenarios with different signal-to-noise ratios and velocities.

The foundation is a construction at the base of the building, which functions to transmit the load from the top of the building structure to the soil layer at the bottom. The pile type foundation is a foundation that is often planned in such conditions. Therefore it is necessary to calculate incorrectly in foundation planning. The method used is the method of description and observation. From the calculation results, the optimal foundation is obtained using a diameter of 40 cm with screw reinforcement D16 distance 125 with the content of 5 reinforcement. When calculating piles, it is better to use pile group control and lateral force control so that the planned foundation construction is able to support the planned load.Pondasi merupakan suatu konstruksi pada bagian dasar bangunan yang berfungsi meneruskan beban dari bagian atas struktur bangunan ke lapisan tanah yang berada di bagian bawahnya Pondasi jenis tiang merupakan pondasi yang sering kali direncakan pada kondisi yang demikian, maka dari itu perlu perhitungan yang tidak tepat pada perencanaan pondasi, metode yang digunakan ialah metode penjabaran dan pengamatan Dari hasil perhitungan, didapat pondasi yang optimal mengunakan diameter 40 cm dengan tulangan besi ulir D16 jarak 125 dengan isi 5 tulangan.

ABSTRACT
Online learning can shorten learning time and of course can save costs incurred by educational institutions. The success of distance learning does not only depend on the material or content presented by the educator, but on how the material is delivered, so that students can understand the material presented by the teacher. The learning model that can be done in elementary schools during the Covid-19 pandemic is distance learning, learning which ideally has interactivity between educators and students even though it is not in the same place, with video conferencing it will help the learning process carried out, because educators will be directly involved with students. Media zoom is one of the choices of learning media in the midst of the Covid-19 pandemic. This research will be conducted at SDN 117 Leppangeng. The objectives of this study are to determine the effectiveness of using zoom media for learning in the midst of the Covid-19 pandemic. The approach used in this research is qualitative.

This article analyzes the indicators of knowledge generation in sugarcane biomass. The impact of the FAPESP research program on bioenergy (BIOEN) is also analyzed, with a focus on the division of biomass and its subareas. Using detailed information from scientific articles in the subareas of Enzymatic hydrolysis, molecular markers, delignification, genotypes, enzymatic conversion, gene expression, nitrogen and photosynthesis, an evaluation of the international insertion of research and collaboration networks of Brazilian researchers is carried out. The methodology, which was based on the works of Verspagen (2007) and Dal Poz (2006), consists of the formation of clusters of publications indexed on the ISI Web of Science database. The selection of publications is guided by search queries based on keywords related to the subareas of biomass division. The software programs VantagePoint and Pajek are used to support the analysis of the information. The principle objective of the study is to identify the global incorporation of efforts to generate knowledge and technological progress in sugarcane biomass carried out by BIOEN. It was possible to identify a number of factors that influence scientific collaboration in the area of biomass, such as geographic distance and the dynamics of scientific collaboration between countries. An analysis of the biomass division of BIOEN, from a global perspective, showed little cooperation between Latin American countries. The results illustrate that Brazil generates the greatest amount of scientific knowledge regarding sugarcane biomass, however, when the subareas are analyzed separately, scientific publications from the US and China are also predominant.

Camera is the main tool for monitoring shrimp underwater with a noninvasive method. Distance of the shrimp underwater with the varying camera causes the monitoring of the estimated shrimp size to be less accurate. This study provides a new solution to detect the distance of shrimp underwater with a camera using the Euclidian distance and triangle similarity algorithm. The problem raised in this study is how to measure the distance of a shrimp underwater with a camera. The method used has several stages, including using the grayscale image method, image thresholding, edge detection, detection of Region of Interest (ROI), determining the position of shrimp coordinates, calculating the length of shrimp coordinates, camera calibration using the triangle similarity algorithm, calculating the estimated distance of shrimp with the camera. The study results obtained a focal length value of 1298.58, the value of the distance between the shrimp and the camera (D') for 5 positions of shrimp underwater from 50 cm – 19.86 cm, and the RE value from 0% - 0.13%. In conclusion, this method can be used to measure the estimated distance between of moving shrimp and a camera with a low error rate.

The development of technology brings impacts in many aspects, include education. The presence of internet rise the access and opportunity for getting the study anywhere and everywhere. Islamic education occupies a strategic position for responding to the development of technology and takes advantage of these opportunities to further innovate in learning to create a conducive, interactive, and acceptable by the challenges and demands of internet generation. The study uses library research with descriptive-analytical method. The data would be displayed and analyzed critically through primary and secondary resources of the topics. The results show that distance and online learning in PAI provide convenience for both students and teachers to carry out the process of learning from anywhere and anytime. Distance and online learning in PAI also cultivate the moral knowing and feeling of PAI materials but in the dimensions of behavior, conventional method is more appropriately. Therefore, the concepts of distance and online learning in PAI have to be combined with conventional learning so that student mastery is not only limited in knowing and feeling but also in behavior. Thus, it is expected that students can master all aspects of PAI include moral knowing, feeling, and behavior.

Full textAbstract:
Morphological features of oospores of <em>Chara baueri </em>A. Braun, one of the rarest charophyte species worldwide, were studied based on 100 oospores collected from a small and temporarily dried mid-field pond near Cedynia, Western Poland. This is the first Polish and fifth presently known locality of this species. For comparison 67 oospores from a German population (similar pond localized near Batzlow, Germany) were also measured. So far, data on morphology of <em>C. baueri </em>oospores as well as the species ecology are limited. The only more detailed study of oospores for this species was earlier performed on 15 oospores from Kazakhstan. Largest polar axis (<em>LPA</em>, length), largest equatorial diameter (<em>LED</em>, width), isopolarity index (<em>ISI </em>= <em>LPA</em>/<em>LED </em>× 100), number of ridges, width of fossa, distance from apical pole to <em>LED </em>(<em>AND</em>) and anisipolarity index (<em>ANI </em>= <em>AND</em>/<em>LPA </em>× 100) were measured. The comparative analysis revealed that the oospores from Poland are generally bigger and more prolate than the German ones. The differences for most of studied parameters were statistically significant. The finding is discussed in the context of habitat differentiation of both studied sites. Moreover, the results obtained of oospore measurements for both populations differs from most of the data known so far from the literature.

Students can study whenever and wherever they want using online learning, which is a popular technique for distance education. However, the students' drive and enthusiasm for learning goes down when they study at home, which is a problem. Students become bored because they do not have time to meet their friends and because there is not enough variety in assignments and learning materials. Because of the importance of motivating children to learn, this KKN focuses on providing knowledge and technical assistance to the instructors of SDN Curahsawo 3 Kabupaten Probolinggo who use a Game-Based Learning approach. The contents of the lectures, questions and answers, and the practice of using the Kahoot program are used to start community service activities. By using Kahoot as a game-based learning tool, participants will be able to produce their own game-based educational materials as a consequence of this community project. An innovative way to motivate children to learn has been developed. Abstrak: Siswa dapat belajar kapan pun dan di mana pun mereka mau menggunakan pembelajaran online, yang merupakan teknik populer untuk pendidikan jarak jauh. Namun, dorongan dan semangat siswa untuk belajar turun ketika mereka belajar di rumah, yang menjadi masalah.

Since 25 March 2020, all schools, colleges, and universities in Poland have indefinitely closed and, where possible, have activated distance learning because of the COVID-19 pandemic. Considering that the undergraduate years are usually characterized by a high prevalence of emotional disorders and sleep problems, it can be expected that the current situation may have a remarkable impact on the student population. This study aimed to investigate the occurrence of sleep problems among Polish university students as well as the relationship of insomnia symptoms severity with psychopathological symptoms, posttraumatic stress disorder (PTSD) symptoms, and behavioral factors, such as substance use, changes in the amount of sleep, and the level of physical activity during the COVID-19 pandemic. Data were collected from 1111 Polish university students via an online survey conducted between IV and VI 2020. The survey included demographic variables, the level of psychopathological symptoms (General Health Questionnaire, GHQ-28), insomnia (Insomnia Severity Index, ISI), and symptoms of posttraumatic stress (Impact of Events Scale-Revised, IES-R). The results showed that over half of the studied group of students had some form of sleep disturbances during the period of data collection, with moderate-to-severe insomnia symptoms noted in 21.6%. At the same time, the majority of the sample declared they slept more during the pandemic. A significant positive correlation was observed between the severity of insomnia symptoms and PTSD symptoms, as well as GHQ scores, increased substance use, and decreased physical activity. An additional association between the presence of dreams related to the event and insomnia symptoms as well as GHQ scores has been found. The results suggest that sleep problems may be prevalent among university students during the pandemic. Moreover, although the symptoms of insomnia, as well as the severity of sleep disturbance, significantly correlated with all the investigated variables, the direction of those associations remains to be established.
