Performance analysis of first order digital sigma delta adc

Ever-growing era of mobile and personal wireless networks, motivated research in several fields of engineering resulted in low power and low cost consumer products. The voice band processing required in mobile applications demand for architectures, which can easily be integrated in single chip SoC applications. The conventional approach is to have a dedicated IC outside the digital ICs to perform analog to digital conversion. The motivation of single chip radios demand for integration of such ADC modules on digital cellular related ICs. Mixed signal design is very challenging and hence usually it is preferred to have separate ADC chip before the ASIC/FPGA. In this paper we present a digital sigma delta ADC architecture, which can perfectly be integrated in any digital IC with a targeted sampling rate of 20 kS/s with more than 80 dB dynamic range.

A memetic algorithm for the inventory routing problem

In this article, we study an Inventory Routing Problem with deterministic customer demand in a two-tier supply chain. The supply chain network consists of a supplier using a single vehicle with a given capacity to deliver a single product type to multiple customers. We are interested in population-based algorithms to solve our problem. A Memetic Algorithm (MA) is developed based on the Genetic Algorithm (GA) and Variable Neighborhood Search methods. The proposed meta-heuristics are tested on small and large reference benchmarks. The results of the MA are compared to those of the classical GA and to the optimal solutions in the literature. The comparison shows the efficiency of using MA and its ability to generate high quality solutions in a reasonable computation time.

Pharmacognostic and preliminary phytochemical investigation of aerial parts of centella asiatica linn

In the Indo-Pak subcontinent, the traditional systems of medicine, both Ayurvedic and Unani, are primarily based on herbs and herb-based preparation for therapy. Therefore, the importance of the herbal identification process remains critical in achieving the desired and successful therapeutic effect. To support the manufacturers and practitioners of both systems, many herbs are still collected from wild sources, as herbal farming is not very developed in this part of the world. During a survey program conducted in different areas of Pakistan, significant lacks and gaps were noted to be present in the identification & characterization of herbs, which needs to be addressed and fulfilled as many species look alike apparently or physically but have different biological or pharmacological activity. Based on this objective and approach, Centella asiatica was selected for the pharmacognostic and preliminary phytochemical investigation to establish a better correlation and to provide useful methods in its identification as the use of Centella asiatica is very common in Pakistan and other South Asian countries for CNS disorders therapy. Therefore, this study aimed to develop & report some and rapid identification methods for Centella asiatica. The present study includes physical, physicochemical, preliminary phytochemical and fluorescence analysis. For the first time, in the present study, NIR and FT-IR spectra of Centella asiatica have been reported for identification. The findings of the present study are quite promising and can be helpful for the manufacturers and researchers in the identification and development of Centella asiatica-based new drugs or formulations.

Crude drug adulteration: a concise review

The adulteration and substitution of crude drugs is a burning problem. No doubt, substitution is helpful in places where the unavailability of particular oil drugs and or unwanted adverse effects of the desired crude drugs are there and have a choice of another drug with similar pharmacological effects and less unwanted aftereffects. However, in most cases, it is unacceptable because the conversion of authentic drugs into substandard medications may cause a variety of adverse effects, from mild and moderate to severe life-threatening reactions. So, understanding all the ways of adulteration and substitution is necessary to rectify this illegal act and maximize consumers' safety. At the end of this review, the Botanical Adulterant Program of the American Botanical Council is also highlighted.

Optimizing grid-connected photovoltaic (pv) battery energy storage through multi-objective ant-lion optimization (moalo)

As the demand for renewable energy continues to rise, it becomes crucial to discover effective ways to enhance grid-connected photovoltaic (PV) battery energy storage systems. The Institute of Petroleum Studies (IPS) complex at the University of Port Harcourt in Rivers State, Nigeria, embarked on a quest to determine the optimal approach for optimizing their PV battery energy storage system. This research aimed to fulfill this need by employing a diverse research methodology, incorporating the innovative MOALO theory. To begin with, the research gathered primary and secondary data to construct models for the power grid, solarPV, and battery. Furthermore, it meticulously analyzed the load profile of the IPS complex, at the University of Port Harcourt. Leveraging the power of the MOALO theory.The researchers accurately sized the system and evaluated the potential outcomes of simultaneously interconnecting all loads. To gauge the system's performance, there was a calculation of various parameters such as economics, random walk, boundary conditioning, entrapping ants, and ant trap development. Remarkably, the outcome showed that the fitness responses between the two trial runs, facilitated by the integration of MOALO, were strikingly similar, revealing a typical concaveconnected shape, which is characteristic of a multi-objective solver. The optimal multi-objective cost implication of the system was estimated to be around 4,300 USD, with a power mismatch performance of approximately -1.7819e+09. Based on these compelling findings, the study concluded that MOALO serves as an impressive optimization tool capable of minimizing power mismatches and optimizing costs. Moreover, it recommended the generation of excess power as a means to achieve sustainability.

Autophagy mechanism, regulation, functions, and disorders

Autophagy is a self-digesting mechanism responsible for removal of damaged organelles, malformed proteins during biosynthesis, and nonfunctional long-lived proteins by lysosome. Autophagy has been divided into three general types depending on the mechanism by which intracellular materials are delivered into lysosome for degradation that is, microautophagy, chaperone-mediated autophagy (CMA), and macroautophagy. In microautophagy cytoplasm material is sequestered through direct invagination to the lysosomal membrane. Whereas in CMA proteins flagged with pentapeptide motif (KFERQ) were selectively degraded through direct translocation into lysosome. Macroautophagy involves the formation of subcellular double-membrane-bound structures called autophagosomes that contain degradable contents of cytoplasm materials and deliver them into lysosomes for breakdown by lysosomal enzymes. The molecular mechanism of autophagy involves several conserved Atg (autophagy-related) proteins. Systems produce modified complexes Atg8-PE and Atg5-Atg12-Atg16 as autophagy regulators. Autophagy is activated in response to diverse stress and physiological conditions. For example, food deprivation, hyperthermia, and hypoxia are mediated by factors like insulin/IGF-1, m-TOR signaling, FOXO transcription factors, and chaperones. The perturbance in autophagy may lead to several types of cancers, myopathies, and neuromuscular disorders. Several autophagy inducers and inhibitors like 3-methyladenine (3-MA), bafilomycin A1, LY294002 (LY), and Velcade have been used to treat disease is an intense field of study.

Employment status of persons living with mental illness in india: ground reality

The main aim of rehabilitation is vocational independence and community integration. Rehabilitation is complete with the person being a productive member within the community. But this is quite a challenging task as can be vouched by any of the professionals working in this field. What are the barriers and facilitators towards employment or return to work in case of persons living with mental illness? Literature shows that multiple factors are governing the ability to take up gainful employment. Most of this literature is about the western world where the social fabric is more supportive of individual autonomy. India lags in its rehabilitation efforts for mental illness. There is still stigma and lack of awareness about mental illnesses. This increases the problem of unemployment within persons living with mental illness manifold. There are very few detailed investigations into the vocational status of persons with mental illness and almost negligent literature existing in the Indian context. Hence, the current review article tries to examine the factors prevailing in the Indian scenario that influences the employment status.

Regards croisés sur les processus d’apprentissage/acquisition implicite des constituants linguistiques des langues par des apprenants

Cet article vise à mettre en évidence les expériences et points de vue de certains auteurs sur l’apprentissage implicite du langage humain. L’apprentissage implicite est une procédure fondamentale. Le comportement devient sensible aux caractéristiques structurales. Dans le premier point de vue, il y a eu trois expériences qui ont montré que les jeunes apprenants sont sensibles aux régularités lexicales qui n’ont pas été explicitement enseignées; la deuxième expérience portait sur l’utilisation de la répétition des lettres quant à la troisième, elle portait sur la préférence des consonnes uniques ou doublées. Les résultats de ces expériences ont montré que les jeunes apprenants sont sensibles à la fréquence de doubles consonnes, à l’identité des consonnes qui peuvent ou ne peuvent pas se répéter. Les difficultés innées à l’apprentissage de la langue ont fait l’objet du deuxième point de vue. Elles sont de deux ordres: la langue en tant qu’un ensemble de séquences sonores et les indices de découverte d’un mot dans un discours. Les enfants segmentent les mots à partir de huit mois. Les connaissances procédurales se mettent en place par la répétition mentale et pratique. Les propriétés structurelles et statistiques sont à la base de l’apprentissage de la langue.
