The present subject matter is related to deep learning-based centroiding of mass scan data generated by high-resolution mass spectrometry (HR-MS) instruments, operated in standalone mode or when connected to other devices including but not limited to gas or liquid chromatography, capillary electrophoresis or ion mobility separation devices. The raw data or analytical data that is received from the HR-MS instruments is first converted into an open source format such as the mzML format, obvious noise is removed by applying ad hoc filters, regions of interest (ROI) are built from the mass scans, ROIs are classified as peak or noise, peak boundaries identified if classified as peak, and centroids recorded as a tuple of median, mean or weighted average mass to charge ratio (denoted as m/z) and area under the curve. The ROI classification and peak boundary detection steps make use of specially trained deep learning methods.

A technique, suitable for real-time processing, is disclosed for pitch tracking by detection of glottal excitation epochs in speech signal. It uses Hilbert envelope to enhance saliency of the glottal excitation epochs and to reduce the ripples due to the vocal tract filter. The processing comprises the steps of dynamic range compression, calculation of the Hilbert envelope, and epoch marking. The Hilbert envelope is calculated using the output of a FIR filter based Hilbert transformer and the delay-compensated signal. The epoch marking uses a dynamic peak detector with fast rise and slow fall and nonlinear smoothing to further enhance the saliency of the epochs, followed by a differentiator or a Teager energy operator, and amplitude-duration thresholding. The technique is meant for use in speech codecs, voice conversion, speech and speaker recognition, diagnosis of voice disorders, speech training aids, and other applications involving pitch estimation.

Accordingly the embodiments herein provide a method for fabricating a neuron oscillator. The neuron oscillator includes a thermal insulating device connected with a resistor and a capacitor in series to produce self-sustained oscillations, where the resistor and the capacitor are arranged in parallel manner. The neuron oscillator eliminates a requirement of an additional compensation circuitry for a consistent performance over a time under heating issues. Additionally, an ON/OFF ratio of the neuron oscillator improves to a broader resistor range. Further, a presence of tunable synaptic memristor functionality of the neuron oscillator provides a reduced fabrication complexity to a large scale ONN. An input voltage required for the neuron oscillator is low (2-3 V) which makes it suitable to use with existing circuitries without using any additional converters. Additionally, an amplitude of the oscillations is a significant fraction of an applied bias which eliminates a need for an amplification.

The present invention provides an innovative reactor design based on coiled flow inverter geometry for carrying out continuous protein refolding reactions in-vitro by dilution method. The reactor consists of an inline mixer followed by a design to provide cross sectional mixing of diluted denatured proteins through flow inversion thereby changing the direction of centrifugal force in helically-coiled tube. The unique feature of Coiled Flow Inverter Reactor (CFIR) is that it improves contact amongst the various entities such as chaotropes, stabilizers, buffer ions, reducing and oxidizing agents and the protein molecules, within the cross section in a low shear environment, thus providing a sharp residence time distribution and stabilizing the refolding reaction by reducing the side reactions that otherwise result in formation of aggregates and oxidized impurities and result in reduced refolding yield. The reactor is also exemplified for its versatility of being applicable to other biotech unit operations by demonstration of continuous precipitation of impurities from cell culture harvest of a monoclonal antibody therapeutic. The proposed invention can be used for achieving homogeneity in concentrations of protein and other reactants throughout the process so as to achieve the desirable outcome of the resulting reaction for protein refolding, precipitation, viral inactivation etc.

Method and injector for controlling gas flow in a duct. The gas flow in the duct is energised by injecting an auxiliary gas into the duct at predetermined locations at the surface of the gas flow in the duct in the direction of the gas flow at an injection angle of 0 to 3° with respect to the axis of the duct and at a skew angle of 0 to 30° with respect to the axial and radial plane of the duct to prevent and/or reconstitute flow separation and to ensure smooth gas flow in the duct. The injector comprises an annular member having an inlet end and an outlet end and being disposed between and fixed to two duct elements forming a duct in a leak tight manner.

This invention includes a steering Mechanism for a vehicle capable of exhibiting four modes of steering, These steering modes include a 4-wheel steering mode for tight situations (wherein the front wheels steer opposite to the rear wheels), a 2-wheel steering mode for road travel (wherein only the front wheels are steered), and a 4-wheel crab steer mode (wherein the front and rear wheels turn in the same direction) and Zero turn radius. The steering action may be achieved by either solely by manual steering signals or automated steering signals or a combination of both. An electronic circuit monitors the position of the wheels at any time and provides required steering signals to the corresponding wheels to make the wheels turn according to the driver's requirements. One or more motors with one or more gear boxes may be used to induce required automated steering in the wheels.

Systems and techniques for processing and forwarding packets are described. During operation, a system can receive a packet on an input port. Next, the system can identify a set of bits in the packet that represents a route from a source node to a destination node in an n-ary tree. The system can then determine an output port based on a subset of the set of bits. Next, the system can determine whether the output port is free. If the output port is not free, the system can use a contention resolution mechanism to store the packet in an on-chip memory or an off-chip memory based on space availability and the packet's priority. If the output port is free, the system can send the packet through the output port.

Selector device for bipolar RRAM is disclosed. This invention relates to high density volatile and nonvolatile memories, and more particularly to selection devices in bipolar resistive random access memory. The present day technology uses positive and negative field on memory device to change resistance states. Various metal oxides used in bipolar RRAM operations display symmetric as well as asymmetric operation. However, there is no selection device which works close to symmetric or even some asymmetric operation. A memory element is proposed for providing high density volatile/non-volatile memory storage which comprises of memory element and bipolar vertical selector device. Further, the selector device is based on punch-through mechanism concept.
