The effect of language, spatial factors, masker type and memory span onspeech-in-noise thresholds in sequential bilingual children.

This study considers whether bilingual children listening in a second language are among those on which higher processing and cognitive demands are placed when noise is present. Forty-four Swedish sequential bilingual 15 year-olds were given memory span and vocabulary assessments in their first and second language (Swedish and English). First and second language speech reception thresholds (SRTs) at 50% intelligibility for numbers and colors presented in noise were obtained using an adaptive procedure. The target sentences were presented in simulated, virtual classroom acoustics, masked by either 16-talker multi-talker babble noise (MTBN) or speech shaped noise (SSN), positioned either directly in front of the listener (collocated with the target speech), or spatially separated from the target speech by 90° to either side. Main effects in the Spatial and Noise factors indicated that intelligibility was 3.8 dB lower in collocated conditions and 2.9 dB lower in MTBN conditions. SRTs were unexpectedly higher by 0.9 dB in second language conditions. Memory span significantly predicted 17% of the variance in the second language SRTs, and 9% of the variance in first language SRTs, indicating the possibility that the SRT task places higher cognitive demands when listening to second language speech than when the target is in the listener's first language.

Macaque parvocellular mediodorsal thalamus: dissociable contributions to learning and adaptive decision‐making

Distributed brain networks govern adaptive decision‐making, new learning and rapid updating of information. However, the functional contribution of the rhesus macaque monkey parvocellular nucleus of the mediodorsal thalamus (MDpc) in these key higher cognitive processes remains unknown. This study investigated the impact of MDpc damage in cognition. Preoperatively, animals were trained on an object‐in‐place scene discrimination task that assesses rapid learning of novel information within each session. Bilateral neurotoxic (NMDA and ibotenic acid) MDpc lesions did not impair new learning unless the monkey had also sustained damage to the magnocellular division of the MD (MDmc). Contralateral unilateral MDpc and MDmc damage also impaired new learning, while selective unilateral MDmc damage produced new learning deficits that eventually resolved with repeated testing. In contrast, during food reward (satiety) devaluation, monkeys with either bilateral MDpc damage or combined MDpc and MDmc damage showed attenuated food reward preferences compared to unoperated control monkeys; the selective unilateral MDmc damage left performance intact. Our preliminary results demonstrate selective dissociable roles for the two adjacent nuclei of the primate MD, namely, MDpc, as part of a frontal cortical network, and the MDmc, as part of a frontal‐temporal cortical network, in learning, memory and the cognitive control of behavioural choices after changes in reward value. Moreover, the functional cognitive deficits produced after differing MD damage show that the different subdivisions of the MD thalamus support distributed neural networks to rapidly and fluidly incorporate task‐relevant information, in order to optimise the animals’ ability to receive rewards.

Three-stage processing of category and variation information by entangled interactive mechanisms of peri-occipital and peri-frontal cortices

Object recognition has been a central question in human vision research. The general consensus is that the ventral and dorsal visual streams are the major processing pathways undertaking objects’ category and variation processing. This overlooks mounting evidence supporting the role of peri-frontal areas in category processing. Yet, many aspects of visual processing in peri-frontal areas have remained unattended including whether these areas play role only during active recognition and whether they interact with lower visual areas or process information independently. To address these questions, subjects were presented with a set of variation-controlled object images while their EEG were recorded. Considerable amounts of category and variation information were decodable from occipital, parietal, temporal and prefrontal electrodes. Using information-selectivity indices, phase and Granger causality analyses, three processing stages were identified showing distinct directions of information transaction between peri-frontal and peri-occipital areas suggesting their parallel yet interactive role in visual processing. A brain-plausible model supported the possibility of interactive mechanisms in peri-occipital and peri-frontal areas. These findings, while promoting the role of prefrontal areas in object recognition, extend their contributions from active recognition, in which peri-frontal to peri-occipital pathways are activated by higher cognitive processes, to the general sensory-driven object and variation processing.

Teacher’s feedback in teaching science in a bilingual Bruneian primary classroom

PurposeThe purpose of this study is to analyze the use of feedback to students by a primary teacher teaching the science topic “Life Cycle” in a Year 5 bilingual Bruneian science classroom.Design/methodology/approachThis study used a discourse analysis of one primary science teacher’s use of feedback to his students when teaching the topic “Life Cycle.” The participant was a male primary science teacher who taught a Year 5 science class in one of the government schools in the Brunei-Muara district. Direct observations and video recordings of the teacher’s three consecutive lessons on the topic “Life Cycle” were collected. The transcripts were developed from the teacher–student interactions in the three lessons. The “Questioning-based Discourse” approach (Chin, 2006) was used to analyze the different types of feedback, and the students’ cognitive processes that emerged from the lesson transcripts. The frequencies of the feedback and students’ cognitive processes were calculated using percentages.FindingsThe findings from the three lesson observations indicate that the teacher’s feedback showed a range of strategies which consisted mostly of accepting students’ answers and feedback to elicit, to focus, to probe, to clarify and to extend, respectively. The findings also reveal that the cognitive processes of the students ranged from recalling, predicting, hypothesizing, evaluating and explaining. The analysis shows that the teacher only practiced low-level questioning and the feedback given to the students was mostly for accepting the students’ answers rather than challenging students’ ideas.Practical implicationsThe findings reported in this study provide useful insights into the importance of teacher–student interactions in the teaching and learning of science. The “Questioning-based Discourse” analytical framework is worthwhile to analyze the science teacher’s talk and consequently to improve teachers” skills in giving feedback that fosters productive students’ responses.Originality/valueThis paper highlights the need for science teachers to analyze their classroom talk and it recommends how to give useful feedback to students to promote higher cognitive processes amongst students. Brunei has been described as a country where there is a linguistic divide determined by the quality of the school that a student attends (Deterding and Salbrina, 2013). Improving the quality of interaction between teacher and students in such circumstances is essential.

Формирование исполнительных функций как основа регулятивных УУД в начальной школе Монтессори

In the following article the questions of the development of regulative universal learning activities in the Elementary Montessori school are concerned. The author notes the connection of these universal learning activities to the operation of executive functions as the higher cognitive processes which are actively studied in the western neuroscience nowadays. In the article there are provided the references to the American and Canadian studies, which point out that Primary and Elementary Montessori schools have benefi cial infl uence on the executive functions. This fact allows us to suggest that the formation of the regulative universal learning activities will be more eff ective with the ultimate use of the executive functions.

Cerebellar Structural Abnormalities Associated With Cognitive Function in Patients With First-Episode Psychosis

Introduction: The fundamental role of the cerebellum in higher cognitive processing has recently been highlighted. However, inconsistent findings exist in schizophrenia with respect to the exact nature of cerebellar structural abnormalities and their associations with cognitive and clinical features.Materials and Methods: We undertook a detailed investigation of cerebellar lobular volumes in 40 patients with first-episode psychosis (FEP) and 40 healthy controls (HCs) using the spatially unbiased atlas template of the cerebellum (SUIT). We examined the functional significance of cerebellar structural abnormalities in relation to cognitive and clinical outcomes in patients.Results: We found that left cerebellar lobules VI and X volumes were lower in FEP patients, compared to HCs. Smaller left lobules VI and X volumes were associated with fewer number of categories completed on the Wisconsin Card Sorting Test (WCST) in patients. In addition, smaller left lobule X volume was related to performance delay on the Trail Making Test (TMT) Part B in patients.Conclusion: Our results demonstrate that cerebellar structural abnormalities are present at the early stage of schizophrenia. We suggest functional associations of cerebellar structural changes with non-verbal executive dysfunctions in FEP.

Is the concept of forgiveness universal? a cross-cultural perspective comparing western and eastern cultures

To understand the conceptualizations of forgiveness more comprehensively, both the cognitive and emotional aspects of forgiveness were investigated across different cultures. Two studies examined cultural similarities and differences in the conceptualizations of forgiveness. In Study 1, we compared idioms of the Chinese and English languages. In Study 2, we compared transgression-related writings between Hong Kong Chinese and Americans. In Study 1 (N = 204), we found that the basic presumptions of forgiveness (i.e., the recognition of transgression and the idea of cancelling debt) were similar across cultures. The cognitive dimension of forgiveness (which involves virtues that preserve social relationships) was more frequently observed in Chinese idioms than English idioms. In Study 2 (N = 68), we found that similar emotional responses (e.g., shame and guilt) arose across cultures following one’s own wrongdoing. Chinese writers were more likely to adopt higher cognitive processing in understanding forgiveness than American writers, as was reflected in their writings.

Effective coverage of essential inpatient care for small and sick newborns in a high mortality urban setting: a cross-sectional study in Nairobi City County, Kenya

BackgroundEffective coverage requires that those in need can access skilled care supported by adequate resources. There are, however, few studies of effective coverage of facility-based neonatal care in low-income settings, despite the recognition that improving newborn survival is a global priority.MethodsWe used a detailed retrospective review of medical records for neonatal admissions to public, private not-for-profit (mission) and private-for-profit (private) sector facilities providing 24×7 inpatient neonatal care in Nairobi City County to estimate the proportion of small and sick newborns receiving nationally recommended care across six process domains. We used our findings to explore the relationship between facility measures of structure and process and estimate effective coverage.ResultsOf 33 eligible facilities, 28 (four public, six mission and 18 private), providing an estimated 98.7% of inpatient neonatal care in the county, agreed to partake. Data from 1184 admission episodes were collected. Overall performance was lowest (weighted mean score 0.35 [95% confidence interval or CI: 0.22–0.48] out of 1) for correct prescription of fluid and feed volumes and best (0.86 [95% CI: 0.80–0.93]) for documentation of demographic characteristics. Doses of gentamicin, when prescribed, were at least 20% higher than recommended in 11.7% cases. Larger (often public) facilities tended to have higher process and structural quality scores compared with smaller, predominantly private, facilities. We estimate effective coverage to be 25% (estimate range: 21–31%). These newborns received high-quality inpatient care, while almost half (44.5%) of newborns needed care but did not receive it and a further 30.4% of newborns received an inadequate service.ConclusionsFailure to receive services and gaps in quality of care both contribute to a shortfall in effective coverage in Nairobi City County. Three-quarters of small and sick newborns do not have access to high-quality facility-based care. Substantial improvements in effective coverage will be required to tackle high neonatal mortality in this urban setting with high levels of poverty.

New Visuality in Art/Science: A Pedagogy of Connection for Cognitive Growth and Creativity

ABSTRACTNew visuality in art/science pedagogies challenges teachers to rethink their curriculum and the role of digital new media in facilitating conceptual thinking and the role of the creative representation of knowledge. Recent neuroscientific research on cognition, perception, memory, and emotion inform and provoke implications for 21st-century learning. Analysis of student artwork uncovers pedagogical challenges for teachers. Teachers use visual learning and its forms of higher process thinking to allow students to make cognitive connections with images, giving them the capacity to integrate concepts for the communication of art/science learning. Examples of student learning from years 3–5 and 15–17 illustrate these ideas.

Neurobiology of Craving: Current Findings and New Directions

This review seeks to provide an update on the current literature on craving and its underlying neurobiology, as it pertains to alcohol and drug addiction. Studies on craving neurobiology suggest that the brain networks activated by conditioned cues in alcohol- and drug-dependent populations extend far beyond the traditional mesolimbic dopamine system and suggest that the early neurobiological theories of addiction, which heavily relied on dopamine release into the nucleus accumbens as the primary mechanism driving cue-induced craving and drug-seeking behavior, are incomplete. Ongoing studies will advance our understanding of the neurobiological underpinnings of addiction and drug craving by identifying novel brain regions associated with responses to conditioned cues that may be specific to humans, or at least primates, due to these brain areas’ involvement in higher cognitive processes. This review highlights recent advances and future directions in leveraging the neurobiology of craving as a translational phenotype for understanding addiction etiology and informing treatment development. The complexity of craving and its underlying neurocircuitry is evident and divergent methods of eliciting craving (i.e., cues, stress, and alcohol administration) may produce divergent findings.

Cognitive-Motor Interference in an Ecologically Valid Street Crossing Scenario.

Laboratory-based research revealed that gait involves higher cognitive processes, leading to performance impairments when executed with a concurrent loading task. Deficits are especially pronounced in older adults. Theoretical approaches like the multiple resource model highlight the role of task similarity and associated attention distribution problems. It has been shown that in cases where these distribution problems are perceived relevant to participant's risk of falls, older adults prioritize gait and posture over the concurrent loading task. Here we investigate whether findings on task similarity and task prioritization can be transferred to an ecologically valid scenario. Sixty-three younger adults (20–30 years of age) and 61 older adults (65–75 years of age) participated in a virtual street crossing simulation. The participants' task was to identify suitable gaps that would allow them to cross a simulated two way street safely. Therefore, participants walked on a manual treadmill that transferred their forward motion to forward displacements in a virtual city. The task was presented as a single task (crossing only) and as a multitask. In the multitask condition participants were asked, among others, to type in three digit numbers that were presented either visually or auditorily. We found that for both age groups, street crossing as well as typing performance suffered under multitasking conditions. Impairments were especially pronounced for older adults (e.g., longer crossing initiation phase, more missed opportunities). However, younger and older adults did not differ in the speed and success rate of crossing. Further, deficits were stronger in the visual compared to the auditory task modality for most parameters. Our findings conform to earlier studies that found an age-related decline in multitasking performance in less realistic scenarios. However, task similarity effects were inconsistent and question the validity of the multiple resource model within ecologically valid scenarios.

Cognitive Rehabilitation in Bilateral Vestibular Patients: A Computational Perspective.

There is evidence that vestibular sensory processing affects, and is affected by, higher cognitive processes. This is highly relevant from a clinical perspective, where there is evidence for cognitive impairments in patients with peripheral vestibular deficits. The vestibular system performs complex probabilistic computations, and we claim that understanding these is important for investigating interactions between vestibular processing and cognition. Furthermore, this will aid our understanding of patients’ self-motion perception and will provide useful information for clinical interventions. We propose that cognitive training is a promising way to alleviate the debilitating symptoms of patients with complete bilateral vestibular loss (BVP), who often fail to show improvement when relying solely on conventional treatment methods. We present a probabilistic model capable of processing vestibular sensory data during both passive and active self-motion. Crucially, in our model, knowledge from multiple sources, including higher-level cognition, can be used to predict head motion. This is the entry point for cognitive interventions. Despite the loss of sensory input, the processing circuitry in BVP patients is still intact, and they can still perceive self-motion when the movement is self-generated. We provide computer simulations illustrating self-motion perception of BVP patients. Cognitive training may lead to more accurate and confident predictions, which result in decreased weighting of sensory input, and thus improved self-motion perception. Using our model, we show the possible impact of cognitive interventions to help vestibular rehabilitation in patients with BVP.

The stressed brain of humans and rodents.

After stress, the brain is exposed to waves of stress mediators, including corticosterone (in rodents) and cortisol (in humans). Corticosteroid hormones affect neuronal physiology in two time‐domains: rapid, non‐genomic actions primarily via mineralocorticoid receptors; and delayed genomic effects via glucocorticoid receptors. In parallel, cognitive processing is affected by stress hormones. Directly after stress, emotional behaviour involving the amygdala is strongly facilitated with cognitively a strong emphasis on the “now” and “self,” at the cost of higher cognitive processing. This enables the organism to quickly and adequately respond to the situation at hand. Several hours later, emotional circuits are dampened while functions related to the prefrontal cortex and hippocampus are promoted. This allows the individual to rationalize the stressful event and place it in the right context, which is beneficial in the long run. The brain's response to stress depends on an individual's genetic background in interaction with life events. Studies in rodents point to the possibility to prevent or reverse long‐term consequences of early life adversity on cognitive processing, by normalizing the balance between the two receptor types for corticosteroid hormones at a critical moment just before the onset of puberty.

De Novo Transcriptome Profiling of Buasbuas (Premna pubescens. Blume)

Buasbuas is the one of the medicinal plants in Indonesia that contains bioactive compounds potential as antimicrobial, antioxidant, antidiabetes, antiinflammation and anticancer. Exploring the pathway and gene related of buasbuas bioactive compounds production has led to the renaissance of understanding buasbuas molecular mechanism database. The aim of this study was to developed data-mining framework of buasbuas to study plant specialized metabolism for phytochemical biosynthesis. Material and Methods: This project was started by collecting shoots and leaves of Buasbuas. Focus of the project was exploring the molecular mechanisms on biosynthesis phytochemical of Buasbuas. Illumina Mi-Seq Next Generation Sequencing was utilized to understand the molecular mechanisms of biosynthesis. Transcriptomes then trimmed and assembled with CLCBio genomic software. Assembled contigs then annotated towards Arabidopsis thaliana using CLC Bio genomic software. Digital Gene Expression was performed to analyze the transcriptional changes in control culture and treatment. Results: There were 5.342 unigenes that expressed only in treatment shoot cultures. Annotation with Gene Ontology showed that 57.9% (3.446) unigenes play role in Biological Process, 56.7% (3.375) unigenes play role in Cellular Components and 63.4% (3.772) unigenes play role in Molecular Functions. Annotation with Kyoto Encyclopedia of Genes and Genomes shows 853 unigenes essentially have role in 24 biological pathways. Highest process with highest unigenes involvement is biosynthesis of plant hormones and biosynthesis of alkaloids. Conclusion: This study showed that phytochemical biosynthesis in buasbuas induces level expression of several genes involved in the jasmonic acid, cytokinin, gibberellin, salicylic acid and ethylene biosynthesis pathway.

A BP Network Control Approach for QoS-Aware MAC in Cloud Robotics

The basic idea of Cloud Robotics is dynamically uploading the compute-intensive applications to the cloud, which greatly enhances the intelligence of robots for the high processing and parallel ability of cloud. However, for the nature of uncertainty of mobility, different kinds of applications on robot may have different Quality of service (QoS). The paper proposes a BP network for QoS-aware MAC(BPFD-MAC) in Cloud Robotics form a view control theory, which can support both absolute and relative QoS guarantees while the energy saving. The hard and soft QoS constraints are de-coupled by normalized into a two-level cascade feedback loop. The former is Active Time Loop (AT-Loop) to enforce the absolute QoS guarantee for real-time application and the later is Contention Window Loop (CW-Loop) to enforce the relative QoS guarantee for Best Effort traffics. Finally, the Back-propagating (BP) neuron network based PID is used for self-tuning parameters and controller design. The hardware experiments demonstrate the feasibility of BPFD-MAC. Comparing with FD-MAC, BPFD-MAC has new feature of absolute QoS support and further developed two advantages:In the condition of heavy loads, BPFD have about 18% great throughput and 14% great power efficient; and in light load, BPFD have lower total energy consumption.

Actual and Perceived Questions Asked by Preceptors with and Without the Use of Bug-in-Ear Technology

Context:Questioning is an instructional strategy used by preceptors to assess knowledge and improve clinical reasoning in students. Preceptors face challenges asking high-level questions, and bug-in-ear (BIE) technology may be one way to address these challenges.Objective:Assess the cognitive level of questions asked by preceptors with and without the use of BIE technology.Design:Mixed methods.Setting:Seven clinical education sites affiliated with 3 Commission on Accreditation of Athletic Training Education–accredited undergraduate athletic training programs.Patients or Other Participants:A total of 13 athletic training students and 8 preceptors.Main Outcome Measure(s):Preceptor-student interactions were observed and audio recorded for 2 days without and 2 days with the availability of BIE technology. Cognitive levels of questions were analyzed using the Question Classification Framework and a 2 (Intervention) × 3 (Question Type) analysis of variance. Interviews were conducted to obtain participants' experiences with and perceptions of questioning and BIE technology. Interviews were analyzed by 2 individuals using an inductive coding process. Trustworthiness was established with member-checking, multiple-analyst triangulation, and data-source triangulation.Results:Preceptors asked 1044 questions, including 46.94% low-level (n = 557), 2.38% high-level (n = 24), and 50.69% other (n = 463), such as yes/no questions, during 149 hours of observation. Preceptors asked more questions during the control sessions than when they used BIE technology (39.1 ± 31.7 versus 26.1 ± 20.4 questions; F1,7 = 6.3; P = .04), although participants perceived the opposite. Two themes emerged from the interview data: (1) Preceptors use questioning to develop clinical reasoning in students, and (2) BIE technology facilitates low-level questioning.Conclusions:Although preceptors primarily asked low-level and basic recall questions of their students during clinical education, participants described the use of strategic sequencing of questions to facilitate clinical reasoning. Preceptors should be encouraged to ask more high-level questions and sequence them to target higher cognitive processing. Bug-in-ear technology was not effective at facilitating effective questioning in clinical education.

Truth is in the head. A nod and shake compatibility effect

Studies from the embodiment perspective on language processing have shown facilitation or interference effects depending on the compatibility between verbal contents, concrete or abstract, and the motion of various parts of the body. The aim of the present study was to test whether such compatibility effects can be found when a higher cognitive process like truth evaluation is accomplished with head movements. Since nodding is a vertical head gesture typically performed with positive and affirmative responses, and shaking is a horizontal head gesture associated with negative and dissenting contents, faster response times can be expected when true information is evaluated by making a vertical head movement and false information by making a horizontal head movement.Three experiments were designed in order to test this motor compatibility effect. In the first experiment a series of very simple sentences were asked to be evaluated as true or false by dragging them vertically and horizontally with the head. It resulted that truth-value was assessed faster when it was compatible with the direction of the head movement, compared to when it was incompatible. In the second experiment participants were asked to evaluate the same sentences as the first experiment but by moving them with the mouse. In the third experiment, a non-evaluative classification task was given, where sentences concerning animals or objects were to be dragged by vertical and horizontal head movements. In the second and third experiment no compatibility effect was observed. Overall results support the hypothesis of an embodiment effect between the abstract processing of truth evaluation and the direction of the two head movements of nodding and shaking. Cultural aspects, cognitive implications, and the limits of these findings are discussed.

Increase of EEG Alpha3/Alpha2 Power Ratio Detects Inferior Parietal Lobule Atrophy in Mild Cognitive Impairment.

The inferior parietal lobule (IPL) has been implicate in many higher cognitive processes, as visuo-motor transformations, tool use or tool making. In subjects with mild cognitive impairment (MCI) at major risk to develop Alzheimer' Disease (AD) an impairment of subtle visuomotor or praxic abilities is a well-known clinical feature. Enhance of the ratio of EEG alpha3/alpha2 frequency power was detected in subjects with MCI who will transform in Alzheimer's disease (AD). We explored of the association of alpha3/alpha2 power ratio with cortical size of IPL in patients with MCI. 74 subjects with MCI undergone EEG recording and MRI scans. Alpha3/alpha2 power ratio in addition to cortical size had been computed for each patient. Three MCI groups had been acquired in keeping with growing tertile values of alpha3/alpha2 ratio. Huge difference of cortical thickness among the groups was calculated. Higher alpha3/alpha2 power ratio group had broader cortical loss compared to other teams on the IPL, particularly in the Supramarginal Gyrus, and Precuneus on both hemispheres. Our results unveil the possible part that the IPL could play in determining the classic alterations of early Alzheimer's disease (AD). Finally, the rise of alpha3/alpha2 power ratio detected a focused anatomo-functional association that could be a reliable marker of incipient AD.

Harnessing functional segregation across brain rhythms as a means to detect EEG oscillatory multiplexing during music listening

Objective. Music, being a multifaceted stimulus evolving at multiple timescales, modulates brain function in a manifold way that encompasses not only the distinct stages of auditory perception, but also higher cognitive processes like memory and appraisal. Network theory is apparently a promising approach to describe the functional reorganization of brain oscillatory dynamics during music listening. However, the music induced changes have so far been examined within the functional boundaries of isolated brain rhythms. Approach. Using naturalistic music, we detected the functional segregation patterns associated with different cortical rhythms, as these were reflected in the surface electroencephalography (EEG) measurements. The emerged structure was compared across frequency bands to quantify the interplay among rhythms. It was also contrasted against the structure from the rest and noise listening conditions to reveal the specific components stemming from music listening. Our methodology includes an efficient graph-partitioning algorithm, which is further utilized for mining prototypical modular patterns, and a novel algorithmic procedure for identifying ‘switching nodes’ (i.e. recording sites) that consistently change module during music listening. Main results. Our results suggest the multiplex character of the music-induced functional reorganization and particularly indicate the dependence between the networks reconstructed from the δ and βH rhythms. This dependence is further justified within the framework of nested neural oscillations and fits perfectly within the context of recently introduced cortical entrainment to music. Significance. Complying with the contemporary trends towards a multi-scale examination of the brain network organization, our approach specifies the form of neural coordination among rhythms during music listening. Considering its computational efficiency, and in conjunction with the flexibility of in situ electroencephalography, it may lead to novel assistive tools for real-life applications.

Design and development of high performance MOS current mode logic (MCML) processor for fast and power efficient computing

Power dissipation and delay product have emerged to be crucial issue, which prove to decrease the performance of microprocessor. The MOS current mode logic (MCML) is an evolving logic family that is attracting interest owing to its high speed operation, reliable performance in comparison to the CMOS logic family. However, the MCML suffers from constant static power dissipation, which, if left unmanaged, would result in an inordinate energy requirement in large scale ICs. In order to resolve this challenge, the newly introduced system designed a modified MOS current mode logic (modified MCML) that has remarkable characteristics of lesser power dissipation, better switching frequency and greater processing speed. With the aim of achieving low power dissipation, the dynamic MOS current mode logic (dynamic MCML) is proposed. Dynamic MCML circuits integrate the benefits of MCML circuits with those that of the dynamic logic families for achieving great performance using a low-supply voltage along with low-power dissipation. The results obtained from simulation show that the newly introduced design model of dynamic MCML yields greater power conservation and higher processing speed in comparison with conventional CMOS technology, MCML and modified MCML with regard to power dissipation and power delay product.
