Due to the lack of channel reciprocity in frequency division duplexity (FDD) massive multiple-input multiple-output (MIMO) systems, it is impossible to infer the downlink channel state information (CSI) directly from its reciprocal uplink CSI. Hence, the estimated downlink CSI needs to be continuously fed back to the base station (BS) from the user equipment (UE), consuming valuable bandwidth resources. This is exacerbated, in massive MIMO, with the increase of the antennas at the BS. This paper propose a fully convolutional neural network (FullyConv) to compress and decompress the downlink CSI. FullyConv will improve the reconstruction accuracy of downlink CSI and reduce the training parameters and computational resources. Besides, we add a quantization module in the encoder and a dequantization module in the decoder of the FullyConv to simulate a real feedback scenario. Experimental results demonstrate that the proposed FullyConv is better than the baseline on reconstruction performance and reduction of the storage and computational overhead. Furthermore, the FullyConv added quantization and dequantization modules is robust to quantization error in real feedback scenarios.

The goal of this research is to evaluate the effects of applied kinesiological activities of different extensions on the transformation of basal-motor abilities of boys. The sample of respondents is represented by boys, students of VII, VIII and IX grades of primary school. „21. March "Matuzići - Doboj South. The total sample consists of a set of 76 respondents classified into three distinct groups. Based on the boys' statements about their participation in everyday physical activities, groups with the numbering were defined through non-athletes: non-athletes-1, recreational athletes-2 and athletes-3. To assess the basic motor skills of the respondents, the variables according to the Eurofit battery test program were used, as follows: Flamingo balance, endurance in the joint, lying-sitting, running 10 × 5m (back and forth), hand tapping, hand dynamometry, flexibility-mobility at the hip joint, jumping away from the spot and running 20m back and forth with progressive acceleration. The results of univariate covariance analysis showed high significance in endurance assessment tests (SHATL 20 and SHATL 10 × 5), followed by static arm strength (MSSIZG), and hand strength (MSSDIN) and torso flexibility (MFLPRK) and balance (MRFLAM). Statistically significant differences in effects did not occur with the three variables, namely hand tapping ( MBFTAR), long jump (MESSDM) or squat-sitting (MRSLSJ). Keywords: Boys, basic motor skills, kinesiological activities, extensibility
Self-inserted urethrovesical foreign bodies are rare in children. A 7-year-old boy inserted a hairpin into the urethra seven days before admission, a diagnosis that was made on the basis of the appearance of blood in the urine, palpation of the base of the penis and two directional X-ray imaging. Cystourethroscopy and suprapubic cystotomy were used to remove the foreign body.The presentation of urethrovesical foreign bodies can vary widely, as can the type of object inserted. Definitive treatment is usually the endoscopic removal, however occasionally surgical intervention may be required. Our novel approach enabled less traumatic removal of the hairpin
Introduction: Human papillomaviruses (HPVs), Epstein-Barr virus (EBV), and mouse mammary tumor virus-like virus (MMTV-like virus) can be present and contribute to breast cancer development and progression. However, the role of these oncoviruses and their crosstalk in breast cancer is still unclear. Methods: We explored the co-presence of high-risk HPVs, EBV, and MMTV-like virus in 74 breast cancer samples from Qatar using PCR. Results: We found the presence of HPV and EBV in 65% and 49% of our cancer sample cohorts; 47% of the samples are positive for both oncoviruses. The MMTV-like virus alone was detected in 15% of the samples with no significant association with clinicopathological features. The three oncoviruses were co-present in 14% of the cases; no significant association was noted between the co-presence of these viruses and the clinicopathological features. Conclusion: Despite the presence of the oncoviruses, additional studies are necessary to understand their interactions in human breast carcinogenesis.
Pathological gambling and alcoholism are addictions with many common characteristics. Unfortunately, this suggests that a person who is prone to developing an addiction very often develops another addiction, or addictive behavior, over time. In this way, a person with a gambling problem can very often develop an addiction to alcohol, just as an alcoholic can develop a pathological gambling problem over time. Factors influencing the development of addiction, alcoholism in gamblers or gambling in alcoholics, are not only characteristics of an individual prone to addiction, but also external, social factors; gambling sites most often include bars while many bars have gambling machines. In this case report, we present one such example, through all stages of its development to treatment, and this includes diagnosis, treatment and post-hospital follow-up. The treatment for these addictions differs, because alcoholism also requires detoxification. However, when realistic and achievable goals are set, as well as triggers identified and the person's awareness is enhanced, alongside educating and engagement of the individual through functional and adequate behaviors, treatment can be very successful. The probability of relapse exists in both forms of addiction, however, it increases significantly if a person has both addictions.
En-bloc tumor resection is the standard treatment for locally advanced colorectal cancer (CRC). An extensive histopathological assessment is necessary to evaluate the metastatic spread and adjuvant therapy. Sentinel lymph node biopsy decreases the histopathological burden when only sentinel lymph nodes (SLNs) are examined. This study aims to evaluate the spread of a magnetic tracer throughout the lymphatic system after ex vivo injection in en-bloc resected specimens of patients with CRC. To achieve this, lymph nodes (LNs) were quantified using a new magnetic detection method. Fifteen patients with CRC diagnosed with clinically negative LNs were included in this study and received 2–4 ex vivo magnetic tracer injections (total volume of 2[Formula: see text]mL). Magnetic sample series were acquired to create a look-up table for magnetic tracer quantification. In 80% of the patients, at least one magnetic LN was detected. A total of 33 LNs were marked as magnetic, containing an average of 8.1[Formula: see text][Formula: see text]g iron. In 71% of the patients, metastases were found in nonmagnetic LNs. Ex vivo injection leads to sub-optimal tracer spread and therefore inaccurate diagnosis. This study presents a novel magnetic detection method to quantify magnetic tracer in lymph nodes. Detecting the SLNs in en-bloc resected specimens and involving only these LNs in histopathological investigation enable a decrease in healthcare costs or an increased diagnostic potential.

<p>The paper focuses on the role of language in a specific socio-political context. It offers a critical<br />approach regarding the representation of political actors in Bosnia-Herzegovina (BiH) in press releases<br />of the Office of the High Representative in BiH, for the period 2006 - 2011. The aim of the linguistic<br />examination is to analyse the notion of the power imbalance between different actors and ideology which<br />is subtly interwoven in the investigated discourse. There are three stages of analysis in the process of<br />linguistic investigation. In the first stage of analysis, the linguistic investigation is carried out by the means<br />of language tools provided by systemic functional grammar. At this stage, the text is analysed at three<br />different levels: ideational, interpersonal, and textual. In the second stage, the logogentic patterns, which<br />emerge as a result of the lexico-grammatical investigation, are further sifted by the analytical framework<br />of critical discourse analysis. In the final stage of the investigation, the text, which is comprehended as a<br />structure realized by clauses, undergoes a pragmatic investigation of presuppositions. The paper shows<br />that the proposed threefold investigation of the text enables the deconstruction of the meaning of the text<br />and at the same time provides an insight into the nature of the relationship between different actors<br />involved in the discourse.</p>
