The coding of a media signal is rendered more efficient by describing the media signal using a sequence of samples and sequentially encoding this sequence by selecting, for a current sample, a set of quantization levels out of a plurality of quantization level sets depending on indices encoded into the data stream for previous samples of the sequence of samples, quantizing the current sample onto one level of the set of quantization levels, and encoding a quantization index to the one level for the current sample into the data stream. In other words, scalar quantization of the individual samples of the sequence of samples is used, but it is rendered dependent on quantization indices encoded into the data stream for previous samples of the sequence of samples. By this measure, it is possible to “construe” a grid of quantization points in the multi-dimensional space across which all possible settings of the sequence of samples are spread, onto which values of the samples are quantized according to the sequence of quantization indices coded into the data stream. This grid, in turn, reduces, statistically, a mean quantization error. |

Methods and systems for processing mass spectra
There is provided a method of identifying spurious peaks in a mass spectrum produced from a time-varying transient signal detected in a mass spectrometer. The method comprises the steps of generating, using a regularized inversion algorithm having one or more adjustable parameters, a first mass spectrum from the time-varying transient signal, according to a first set of values of said one or more adjustable parameters. Generating, using the regularized inversion algorithm, one or more perturbed mass spectra from the transient signal, according to one or more respective perturbed versions of the first set of values. Identifying one or more spurious peaks in the first mass spectrum by comparing the first mass spectrum with at least one of the perturbed mass spectra. There are also provided corresponding systems and computer readable media. |

Method for determining the integrity of a deposit of a complex based on a biological sample and system for carrying out said method
A method for determining the integrity of at least one complex based on at least one biological sample and at least one matrix, including at least the following steps:—acquiring at least one image,—analyzing the image sent by extracting light intensity values representative of at least one spectral band,—relating the light intensity values to one another to obtain representative spectral data,—determining a state of integrity of the complex by comparing each of the representative spectral data by similarity grouping with a determined similarity threshold,—triggering at least one first alert, by the analysis unit, when the representative data are similar to the first state of integrity or to the second state of integrity. |

Method and apparatus for metal and ceramic nanolayering for accident tolerant nuclear fuel, particle accelerators, and aerospace leading edges
A system is described that includes a sputter target and a magnetic element array including multiple sets of magnets arranged to have a Hall-Effect region that extends along a length of the sputter target. The elongated sputtering electrode material tube is interposed between the magnetic array and an object to be deposited with a sputtered material from the sputter target. During a direct current high-power impulse magnetron sputtering operation, the system performs a depositing on a surface of the object by generating and controlling an ion and neutral particle flux by: providing a vacuum apparatus containing a sputter target holder electrode; first generating a high-power pulsed plasma magnetron discharge with a high-current negative direct current (DC) pulse to the sputter a target holder electrode; and second generating a configurable positive voltage kick pulse to the sputter target holder electrode after terminating the negative DC pulse. |

Audio keyboard button with varying output
There is provided a button for varying output based on force applied. The button comprises: a contact pad with at least two contacts, the contacts being arranged in a complementary pattern of interdigitated fingers with a separation therebetween; and an actuator and a conductive layer, the conductive layer being located between a base of the actuator and the contact pad and being independent of the actuator and contact pad, the base of the actuator being shaped to increase the surface area of the conductive layer in contact with the contacts as the actuator is pushed towards the contact pad. This increases current flow between the contacts in use as the force applied to the actuator increases. |

Photovoltaic structure and method of fabrication
A photovoltaic device includes one or more features that taken alone or in combination enhance its efficiency. Some embodiments may comprise a tandem solar device in which a top PV cell is fabricated upon a front transparent substrate, that also serves as the top encapsulating substance. The top PV cell including the front encapsulating substance is then bonded (e.g., using adhesive) to a bottom PV cell in order to complete the tandem device. Using the same transparent, insulating element as both front encapsulating substance and a substrate for fabricating the top PV cell, obviates to the need to provide a separate structure (with resulting interfaces) to perform the latter role. For tandem and non-tandem PV devices, a Through-Substrate-Via (TSV) structure may extend through an insulating substrate in order to provide contact with an opposite side (e.g., back electrode). Embodiments may find particular use in fabricating shingled perovskite photovoltaic solar cells. |
