Radio Over Fiber Downlink Design for Spatial Modulation and Multi-Set Space-Time Shift-Keying

open access: yesIEEE Access, 2018
Spatial modulation (SM) and multi-set space-time shift-keying (MS-STSK) are capable of striking a flexible design trade-off between the multiplexing and diversity gains attained.

Predictive ECG coding using linear time-invariant models [PDF]

open access: yesArchive of Oncology, 2004
Electrocardiogram (ECG) signal compression suffers of lack of standards for analogue-digital conversion. Results of this study have shown that 8 bits/sample, although frequently in use, does not satisfy quality criteria for medical doctors.

Measurement of definite integral product of two more signals using two-bit ADCs [PDF]

open access: yesZbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2012
This paper presents the two-bit stochastic converter theory of operation. This converter could be used for the precise measurement of the effective (root-mean-square) value of voltage, current, electric power or energy and thus, could be applicable to ...

A 10 MHz‐BW 85 dB‐SNDR 4th‐order sturdy MASH 2‐0 noise shaping SAR ADC with 2nd‐order gain‐error‐shaping technique

open access: yesElectronics Letters
The multi‐stage noise shaping (MASH) ΣΔ ADC has a good potential to achieve high‐order noise shaping (NS) and high resolution. However, it suffers from quantization noise leakage caused by the mismatch between the analogue NS filter and the digital ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

A bridged‐switch energy‐efficient switching scheme for SAR ADCs with 2× input range

open access: yesElectronics Letters
In recent years, successive approximation register (SAR) analogue‐to‐digital converters (ADCs) have been widely applied in Internet of Things (IoT) sensor devices.

A Simplified Method of Pure Time Delay Generation

open access: yesMeasurement + Control, 1978
A method of time delay generation is described that is not dependent on a Pade or similar approximation. It is shown that the use of a serial analogue to digital conversion technique known as Delta Modulation can result in a simple and low cost ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Energy‐efficient switching method using input‐swapping for high‐resolution successive approximation register analog‐to‐digital converters

open access: yesElectronics Letters
This paper presents an energy‐efficient digital‐to‐analog converter (DAC) switching method with low common‐mode variations for high‐resolution successive approximation register (SAR) analog‐to‐digital converters (ADCs), while enabling to implement ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...
