Although noise-based logic shows potential advantages of reduced power dissipation and the ability of large parallel operations with low hardware and time complexity the question still persist: Is randomness really needed out of orthogonality? In this Letter, after some general thermodynamical considerations, we show relevant examples where we compare the computational complexity of logic systems based on orthogonal noise and sinusoidal signals, respectively. The conclusion is that in certain special-purpose applications noise-based logic is exponentially better than its sinusoidal version: Its computational complexity can be exponentially smaller to perform the same task.

Objective: To compare the clean intermittent self-catheterization (CISC) with continuous indwelling catheterization (CIDC) in relieving acute urinary retention (AUR) due to benign enlargement of prostate (BEP). Materials and Methods :A total 60 patients attending in urology department of Dhaka Medical college hospital were included according to inclusion criteria ,Patients were randomized by lottery into two groups namely group –A and group –B for CISC and IDC drainage respectively . Thus total 60 patients 30 in each group completed study. Results : Most men can safely be managed as out-patients after AUR due to BPH. The degree of mucosal congestion and inflammation within the bladder was found to be lower in those using CISC and the bladder capacity in these patients was also found higher.Patients with an IDC had a high incidence of UTIs then that of patients with CISC. During the period of catheterization the incidence of UTI was 43.3% in group B in comparison to 40% in group A; before TURP 36% in group B in comparison to 10% incidence in group A.According to patient’s opinion CISC is better than IDC in the management of AUR. Experiencing bladder spasm, reporting blood in urine, management difficulties, incidence and severity of pain were less in CISC group, and the method of CISC was well accepted by patients as well as their family members. Conclusion: From the current study it may be suggested that CISC is better technique for management of AUR patient due to BPH than IDC. It can also be very helpful when surgery must be delayed or avoided due to any reasons in this group of patients. Bangladesh Journal of Urology, Vol. 21, No. 2, July 2018 p.105-110

In telemedicine, medical images are always considered very important telemedicine diagnostic evidences. High transmission delay in a bandwidth limited network becomes an intractable problem because of its large size. It’s important to achieve a quality balance between Region of Interest (ROI) and Background Region (BR) when ROI-based image encoding is being used. In this paper, a research made on balancing method of LS-SVM based ROI/BR PSNR prediction model to optimize the ROI encoding shows it’s much better than conventional methods but with very high computational complexity. We propose a new method using extreme learning machine (ELM) with lower computational complexity to improve encoding efficiency compared to LS-SVM based model. Besides, it also achieves the same effect of balancing ROI and BR.

Loiss is a novel byte-oriented stream cipher proposed in 2011. In this paper, based on solving systems of linear equations, we propose an improved Guess and Determine attack on Loiss with a time complexity of 2231and a data complexity of 268, which reduces the time complexity of the Guess and Determine attack proposed by the designers by a factor of 216. Furthermore, a related key chosenIVattack on a scaled-down version of Loiss is presented. The attack recovers the 128-bit secret key of the scaled-down Loiss with a time complexity of 280, requiring 264chosenIVs. The related key attack is minimal in the sense that it only requires one related key. The result shows that our key recovery attack on the scaled-down Loiss is much better than an exhaustive key search in the related key setting.

Before chatbots there were simply bots: The invention of a chatbot brought us to the new era of technology, the era of conversation service. A chatbot is a virtual person that can effectively talk to any human being with the help of interactive conversion textual skill. Now a days there are many cloud-based platforms available for developing and deploying the chatbot such as Microsoft bot framework, IBM Watson, Kore, AWS lambda, Microsoft Azure bot service, Chatfuel, Heroku and many more but all those techniques has some drawbacks such as built-in Artificial Intelligence, NLP, conversion service, programming etc. This paper represents the comparison between all cloud-based chatbot technologies with some constraint such as built-in AI, setup time, completion time, complexity etc. Finally, by the comparison, we will get to know that which cloud platform is efficient and suitable for developing chatbot.

Multilevel thresholding is a popular image segmentation technique. However, computational complexity of multilevel thresholding increases very rapidly with increasing number of thresholds. Metaheuristic algorithms are applied to reduce computational complexity of multilevel thresholding. A new method of multilevel thresholding based on Moth-Flame Optimization (MFO) algorithm is proposed in this paper. The goodness of the thresholds is evaluated using Kapur's entropy or Otsu's between class variance function. The proposed method is tested on a set of benchmark test images and the performance is compared with PSO (Particle Swarm Optimization) and BFO (Bacterial Foraging Optimization) based methods. The results are analyzed objectively using the fitness function and the Peak Signal to Noise Ratio (PSNR) values. It is found that MFO based multilevel thresholding method performs better than the PSO and BFO based methods.

Eleven laboratories across Canada took part in a comparative study of modified versions of the “FDA” and “USDA” methods for the detection of Listeria monocytogenes in foods and environmental samples. Both were modified by the inclusion of additional plating media and the use of modified Fraser broth in the modified “FDA” method. Approximately 92% of the positive samples were detected after 24 h of enrichment. Testing of routine samples by the participating laboratories showed no significant difference (p<0.05) in ability to isolate L. monocytogenes by either the modified “FDA” or “USDA” methods. However, the modified “FDA” method isolated significantly more positives (16.8%) from the spiked foods/controls than the modified “USDA” method (p<0.05). For all samples tested by both methods in the same laboratory, again the modified “FDA” method significantly out performed the “USDA” version by approximately 6% (p<0.05). However, the spiked foods/controls tested by both methods in the same laboratory showed no difference (p<0.05) in their ability to isolate L. monocytogenes. Overall, the modified “FDA” and “USDA” methods were comparable (within 1.0%) in their ability to isolate this microorganism. The “USDA” preenrichment broth maintained its initial pHbetter. Modified Fraser broth, in principle, proved to be useful as a screening tool but is not very selective. Oxford agar proved to be marginally better than lithium chloride-phenylethanol-moxalactam medium and significantly (p<0.05) better than modified Oxford agar in isolating L. monocytogenes.

The aim of this study is to compare the tissue response between the ridgelap pontic and modified ridgelap pontic. Total patients were 40. The fixed prosthesis were cemented by temporary cementing material. After providing the treatment, instruction on maintenance of prosthesis. Patients were visited and studied after 6 weeks, 12 weeks and 6 months to observe the condition of tissue response beneath pontic. The following necessary data were collected in respect of the condition of tissue beneath the pontic, color of gingiva. The modified ridgelap pontic is better than ridgelap pontic regarding tissue response. The tissue response with the ridgelap surface of the pontic of fixed partial denture in 1st molar missing tooth enhanced the condition of the mucous membrane beneath the tissue surface of the pontic, condition of the abutment tooth, between ridge surface of the pontic and mucosa overlying the edentulous ridge achieved better success regarding fixed partial denture.Update Dent.
