Digital signal propagation delay in a nano-circuit containing reactive and resistive elements

The transient switching delay in a micro/nano-scale circuit containing resistive and reactive elements are sternly affected by the surge in the resistance arising from sub-linear current-voltage (I-V) characteristics limited by the velocity and current saturation. The saturation arises due to the realignment of randomly oriented velocity vectors to the unidirectional streamlined ones in a high electric field when voltage applied across a resistor exceeds its decreasing critical value with reduced channel length. The frequency response f = 1/2πτt is affected by a transit time delay τt is lower than that predicted from the application of Ohm's law. The resistance surge dramatically boosts the RC time constant and switching delay and attenuates the L/R time constant and switching delay

Cyclic oxidation behaviour of low alloy steel And aisi 304 steel inair at 900oc

The oxidation behaviour of Low alloy steel its German designation (20mnmoni55) and AISI 304 steel has been studied in air under cyclic conditions at 900°C for 50 hr cyclic. Oxidation kinetics was established by thermogravimetric technique. Each cycle consisted of 1 hour heating at 900°C followed by 20 min of cooling in air. Low alloy steel sample followed somewhat linear rate of oxidation with more weight gain while AISI 304 sample followed the non-linear rate law of oxidation with less weight gain. The microstructural feature and phase transformation of oxide scales were characterise by X-ray diffraction (XRD) and field emission scanning electron microscopy/energy dispersive X-ray (FESEM/EDAX) techniques

Forens(om)ic medicine: omics in forensic medicine

The branch of science informally known as ‘omics’ are various branches in biology whose names end in the suffix omics such as proteomics, metabolomics, genomics, transcriptomics. The studies regarding the role of omics in various branches of medical field have become an upcoming area and its rising trend has been observed in the last decade. Omics has very recently emerged as an uprising field in forensic medicine also which is already known for its great participation with other branches like forensic toxicology, biochemistry, psychiatry, genetics. The use of state- of-the-art omics technologies has been explored in forensic medicine and sciences in establishing post mortem interval, drugs of abuse, intoxication and cause of death. The various forensic studies presently are aiming omics for future prospective. An elementary attempt has been made in this review article to briefly present the role and advantages of omics in forensic medicine. We, hereby, propose to call it forensomic medicine, to draw attention of the forensic professionals to this novel branch of science in order to encourage new studies to be used in medico legal applications

FUTURISTIC SCPOPE OF BIOMARKERS IN TUBERCULOSIS

ABSTRACTOne of the major causes of the mortality from single infectious agent, tuberculosis (TB) is prevalent worldwide. India has the highest number of TBcases in the world. It is the leading cause of death, because of its high mortality and morbidity because of the disease. Reason lies in the emergenceof multidrug-resistant TB strains, and the HIV infection, which reactivates the latent TB making it more severe. Moreover, failure to diagnose TBearly remains one of the primary hurdles in controlling of the disease. TB is a potentially hazardous infectious disease attacks various organs, mainlyaffecting lungs. The bacteria causing TB are spread from one person to another. Tiny droplets released into the air via coughs and sneezes lead to thepassage of infection. The disease is generally diagnosed by its symptoms, radiographic methods, and sputum smear microscopy and by cultivation ofthe Mycobacterium tuberculosis, which is considered as gold standard. Current advances in molecular biology and molecular epidemiology and a betterunderstanding of drug resistance in TB have given a new horizon to its rapid diagnosis. However, the cost-effective techniques, and their requirementfor sophisticated equipment and skilled personals have excluded their implementation on a routine basis, especially in low-income countries.Keywords: Biochemical markers, Tuberculosis, Microbiological tuberculosis

Concentration dependence of drift and magnetoresistance ballistic mobility in a scaled-down metal-oxide semiconductor field-effect transistor

The degradation of ballistic mobility in a metal-oxide semiconductor field-effect transistor is attributed to the nonstationary ballistic injection from the contacts as the length of a channel shrinks to the length smaller than the scattering-limited mean free path. Apparent contradiction between the rise of magnetoresistance mobility and fall of drift mobility with increasing channel concentration is attributed to scattering-dependent magnetoresistance factor. The ballistic mean free path of injected carriers is found to be substantially higher than the long-channel drift mean free path. Excellent agreement with the experimental data on length-limited ballistic mobility is obtained

Microcircuit modeling and simulation beyond Ohm's law

Circuit theory textbooks rely heavily on the applicability of Ohms law, which collapses as electronic components reach micro-and nanoscale dimensions. Circuit analysis is examined in the regime where the applied voltage V is greater than the critical voltage $Vc, which triggers the nonlinear behavior. The critical voltage is infinity in the Ohmic regime, but is as low as a fraction of a volt when linear currentvoltage characteristics become sublinear and the resistance surges due to current saturation effects. For two resistors of the same Ohmic values but of differing lengths, the shorter resistor is more susceptible to this effect. In addition, the power consumed in this regime is a linear function of voltage as compared to quadratic behavior in the Ohmic regime. Several possible applications are suggested

Diversity of 4-Chloro-2-nitrophenol-Degrading Bacteria in a Waste Water Sample

Eighteen bacterial strains, isolated from a waste water sample collected from a chemically contaminated site, Patancheru (17°32′N 78°16′E/17.53°N 78.27°E), India, were able to decolorize 4-chloro-2-nitrophenol (4C2NP) in the presence of an additional carbon source. These eighteen 4C2NP-decolorizing strains have been identified as members of four different genera, including Bacillus, Paenibacillus, Pseudomonas, and Leuconostoc based on the 16S rRNA gene sequencing and phylogenetic analysis. Most of the bacteria (10) belonged to the genus Bacillus and contributed 56% of the total 4C2NP-degrading bacteria, whereas the members of genera Paenibacillus and Pseudomonas represented 22% and 17%, respectively, of total 4C2NP-degrading isolates. There was only one species of Leuconostoc capable of degrading 4C2NP. This is the first report of the diversity of 4C2NP-decolorizing bacteria in a waste water sample. Furthermore, one bacterium, Bacillus aryabhattai strain PC-7, was able to decolorize 4C2NP up to a concentration of 2.0 mM. Gas chromatography-mass spectrometry analysis identified 5-chloro-2-methylbenzoxazole as the final product of 4C2NP decolorization in strain PC-7

Ballistic mobility and saturation velocity in low-dimensional nanostructures

Ohm's law, a linear drift velocity response to the applied electric field, has been and continues to be the basis for characterizing, evaluating performance, and designing integrated circuits, but is shown not to hold its supremacy as channel lengths are being scaled down. In the high electric field, the collision-free ballistic transport is predicted, while in low electric field the transport remains predominantly scattering-limited in a long-channel. In a micro/nano-circuit, even a low logic voltage of 1 V gives an electric field that is above its critical value εc (εnot double greater-than signεc) triggering non-ohmic behavior that results in ballistic velocity saturation. The saturation velocity is an appropriate thermal velocity for a non-degenerate and Fermi velocity for a degenerate system with given dimensionality. A quantum emission may lower this ballistic velocity. The collision-free ballistic mobility in the ohmic domain arises when the channel length is smaller than the mean free path. The results presented will have a profound influence in interpreting the data on a variety of low-dimensional nanostructures

Role of Human Oral Microbiome in Diseases

The human oral microbiome represents a diverse and intricate ecosystem comprising bacteria, fungi, viruses, and protozoa. It plays a vital role in numerous physiological processes, ranging from digestion to immunity. Recent research endeavors have focused on delineating the composition and functions of the oral microbiome. Changes in the oral microbiome have been associated with both oral diseases (such as dental caries, periodontitis, halitosis) and systemic conditions (including cardiovascular disease, diabetes, and cancer). Despite significant advancements, numerous questions about the role of the oral microbiome in health and disease remain unanswered. Further research is imperative to explore the intricate interactions between the oral microbiome and other microbiomes within the body. Additionally, there is a need to develop targeted interventions capable of selectively modulating the oral microbiome without disrupting other beneficial microorganisms. In summary, delving into the study of the human oral microbiome has the potential to revolutionize our comprehension of health and disease, opening avenues for innovative approaches to preventive and therapeutic medicine
