Speech Scrambling based on Particle Swarm Optimisation

Securing any communication system where important data may be transmitted through the channel is a very crucial issue. One of the good solutions in providing security for the speech is to use speech scrambling techniques. The chaotic system used in security has properties that make it a good choice for scrambling speech signal and the optimisation algorithm can provide a perfect performance when used to enhance the hybrid of more than one method. In this paper, we suggest a system that uses an optimisation method, namely, particle swarm optimisation. The evaluation measures prove that the output of the optimisation method has better performance among the methods used in the comparison, including chaotic maps and hybrid chaotic maps.

PPARγ Targets-Derived Diagnostic and Prognostic Index for Papillary Thyroid Cancer

In most cases, papillary thyroid cancer (PTC) is highly curable and associated with an excellent prognosis. Yet, there are several clinicopathological features that lead to a poor prognosis, underscoring the need for a better genomic strategy to refine prognostication and patient management. We hypothesized that PPARγ targets could be potential markers for better diagnosis and prognosis due to the variants found in PPARG in three pairs of monozygotic twins with PTC. Here, we developed a 10-gene personalized prognostic index, designated PPARGi, based on gene expression of 10 PPARγ targets. Through scRNA-seq data analysis of PTC tissues derived from patients, we found that PPARGi genes were predominantly expressed in macrophages and epithelial cells. Machine learning algorithms showed a near-perfect performance of PPARGi in deciding the presence of the disease and in selecting a small subset of patients with poor disease-specific survival in TCGA-THCA and newly developed merged microarray data (MMD) consisting exclusively of thyroid cancers and normal tissues.

Feature Counting Is Impaired When Shifting Attention Between the Eyes in Adults With Amblyopia

BackgroundFeature counting requires rapid shifts of attention in the visual field and reflects higher-level cortical functions. This process is drastically impaired in the amblyopic eye of strabismic amblyopes. In this study, we hypothesized that feature counting performance in anisometropic and strabismic amblyopes is further impaired when shifts in attention is required between the eyes.Materials and MethodsThrough a mirror stereoscope, highly visible Gabor patches were presented to the same eye within a block or randomly presented to the left eye or to the right eye with an equal probability within a block. The task was to report the number of Gabors (3 to 9) as accurately as possible. Counting performance was compared between the amblyopes and the normal-vision observers and between the viewing conditions (shifting attention between the eyes versus maintaining attention in the same eye).ResultsWhen attention was maintained in the same eye, the amblyopic eye of both anisometropic and strabismic groups undercounted the number of Gabors, but achieved near-perfect performance with their fellow eye, compared to normal-vision observers. In contrast, when shifting attention randomly to the left or to the right eye, the amblyopic eye further undercounted the number of Gabors. Undercounting was also found in the fellow eye of strabismic amblyopes, but was not in the fellow eye of anisometropic amblyopes. Performance in normal-vision observers did not differ between shifting attention between the eyes and maintaining attention in the same eye.ConclusionOur data showed that the amblyopic eye of both anisometropic and strabismic amblyopes further undercounted features when shifting attention between the eyes, compared to when maintaining attention in the same eye. This suggests that the ability to quickly redirect attention, particularly under interocular suppression, is impaired in amblyopia. The fellow eye of strabismic amblyopes also undercounted features when shifting attention between the eyes. However, such fellow eye abnormality was not found in anisometropic amblyopes, suggesting that different patterns of visual deficits are associated with amblyopia of different etiologies. The inability to count multiple features accurately reflects dysfunctions of high-level cortices in the amblyopic brain.

German Language Adaptation of the NAVS (NAVS-G) and of the NAT (NAT-G): Testing Grammar in Aphasia

Grammar provides the framework for understanding and producing language. In aphasia, an acquired language disorder, grammatical deficits are diversified and widespread. However, the few assessments for testing grammar in the German language do not consider current linguistic, psycholinguistic, and functional imaging data, which have been shown to be crucial for effective treatment. This study developed German language versions of the Northwestern Assessment of Verbs and Sentences (NAVS-G) and the Northwestern Anagram Test (NAT-G) to examine comprehension and production of verbs, controlling for the number and optionality of verb arguments, and sentences with increasing syntactic complexity. The NAVS-G and NAT-G were tested in 27 healthy participants, 15 right hemispheric stroke patients without aphasia, and 15 stroke patients with mild to residual aphasia. Participants without aphasia showed near-perfect performance, with the exception of (object) relative sentences, where accuracy was associated with educational level. In each patient with aphasia, deficits in more than one subtest were observed. The within and between population-groups logistic mixed regression analyses identified significant impairments in processing syntactic complexity at the verb and sentence levels. These findings indicate that the NAVS-G and NAT-G have potential for testing grammatical competence in (German) stroke patients.

URBAN SPORTS SERVICE STRUCTURE FROM THE PUBLIC HEALTH CONTEXT

ABSTRACT With the improvement of the quality of life, the residents’ requirements for the construction of urban public sports services have gradually improved. In order to improve the current urban public sports service system, this study analyzes the existing public sports service through the construction of public sports service model. The results show that the current construction of public sports service has some defects, such as single construction subject, unbalanced regional development of sports service, lack of perfect performance evaluation mechanism of sports public service, and so on. Therefore, in the process of public sports service construction, we need to pay attention to the diversification of construction subjects, the cultivation of residents’ awareness of physical exercise, the improvement of performance evaluation mechanisms of sports public services, and the broadening of investment channels. These measures can improve the urban public sports service system from the perspective of public health, and create better quality public sports services. This study analyzes the problems existing in the construction of public sports service by building a model, and puts forward some suggestions for improvement, hoping to provide ideas for scholars who study related experiments.

Secure User Authentication using Captcha as Passwords based on Graphical Methods

An alternative to traditional text-based password is being proposed. This aims to enhance the safety and security of the current system by adding a layer of additional security, the proposed system uses FIDO (Fast Identity Online) which unlike password catalogue, stores personally recognizing information data locally on the handler's device to defend it. FIDO's personal identification and local storing of biometric is an intended way to ease user apprehensions about personal data. Image-captchas have lately developed into a very prevalent and extensively organized crossways throughout the online networks to guard from the offensive things. Still, the developing competence in the system field has steadily weakened the safety of Image-captcha and has exposed them to attacks. Built on our valuation, we roughly recognize the defects in these methods of prominent structures, laterally with the perfect performance and plan. Ideologies for more secure captchas are formed from our findings which lean-to light on the considerate of measure and impact, for captcha solving.

Maimonides and his Predecessors on Dying for God as “Sanctification of the Name of God”

Maimonides’ view of the significance of dying for God, I will argue, is his understanding of the phrase that the rabbis appropriated (at least by the Middle Ages) for dying in martyrdom scenarios—namely, “Qiddush HaShem,” literally: “Sanctification of the Name [of God].” For Maimonides, a holy life is no more but also no less than a life constituted by perfect performance of all commandments in the Mosaic Law without exception. Does this ideal allow for—indeed mandate in specific circumstances—transgressing rather than dying, especially when coerced? Or does a truly holy life require nothing less than perfect performance of all commandments allowing for no violations under any circumstances? The view that demands perfect observance of all commandments in all circumstances, I will call “holiness perfectionism.” Maimonides, I shall argue, offers a critique of this view.
