Advancements in stem cell technology together with an improved understanding of in vitro organogenesis have enabled new routes that exploit cell-autonomous self-organization responses of adult stem cells (ASCs) and homogenous pluripotent stem cells (PSCs) to grow complex, three-dimensional (3D), mini-organ like structures on demand, the so-called organoids. Conventional optical and electrical neurophysiological techniques to acquire functional data from brain organoids, however, are not adequate for chronic recordings of neural activity from these model systems, and are not ideal approaches for throughput screenings applied to drug discovery. To overcome these issues, new emerging approaches aim at fusing sensing mechanisms and/or actuating artificial devices within organoids. Here we introduce and develop the concept of the Lab-in-Organoid (LIO) technology for in-tissue sensing and actuation within 3D cell aggregates. This challenging technology grounds on the self-aggregation of brain cells and on integrated bioelectronic micro-scale devices to provide an advanced tool for generating 3D biological brain models with in-tissue artificial functionalities adapted for routine, label-free functional measurements and for assay's development. We complete previously reported results on the implementation of the integrated self-standing wireless silicon micro-devices with experiments aiming at investigating the impact on neuronal spheroids of sinusoidal electro-magnetic fields as those required for wireless power and data transmission. Finally, we discuss the technology headway and future perspectives. [ABSTRACT FROM AUTHOR]

This letter describes a single-transistor oscillator implemented on a paper substrate at the operating frequency of 24 GHz, based on a design procedure that makes it possible to overcome the limitations caused by thin high-loss substrates and package parasitics of commercial components. The commercial transistor adopted in the oscillator is led to instability by exploiting its parasitic gate inductance. The drain network compensates for the parasitic inductance of the transistor package and connects the oscillator circuit to a 50- $\Omega $ load resistance. Finally, an external inductor at the source terminal is used to resonate out the capacitive contribution of the circuit at the oscillation frequency. Overall, the active device appears in a quasi-common-drain stage. Experimental results on prototype show that the oscillator exhibits an output power of +6.2 dBm at 24 GHz, with a dc power consumption of 72.5 mW. [ABSTRACT FROM AUTHOR]

River discharge is an important variable to measure in order to predict droughts and flood occurrences. Once the cross-sectional geometry of the river is known, discharge can be inferred from water level and surface flow velocity measurements. Since river discharges are of particular interest during extreme weather events, when river sites cannot be safely accessed, noncontact sensing technologies are particularly appealing. To this purpose, this work proposes a prototype of a low-cost continuous wave (CW) Doppler radar sensor, which is able to monitor the surface flow velocity of rivers. The prototype is tested at two gauged sites in central Italy, along the Tiber River. The surface flow velocity distribution across the river is monitored by means of the analysis of received Doppler signal. The surface velocity statistics are then extracted using a novel algorithm that is optimized to run on a microprocessor platform with minimal computing power (ArduinoUNO). In particular, the radar measurements are used to initialize a 2-D entropy-based velocity model (EVM) that is able to estimate river discharges in any flow condition. Finally, the results concerning the observed discharge provided by the EVM prove to be comparable with those obtained with more expensive commercial solutions. The results are important since the described methodology can be extended to small-size Doppler radar sensors onboard unmanned aerial vehicles (UAVs), the latter providing a method for mapping surface velocity of rivers.

Summary: We propose a novel CMOS differential voltage‐controlled equivalent active resistor based on a modified common‐source cross‐coupled pair. The equivalent resistance exhibited by the circuit can be tuned to be either positive or negative through the tail current, which is controlled by a bias voltage. The complete cell comprises four transistors, two resistors in addition to the bias voltage, and tail current source. Application to the design of oscillators is demonstrated by theoretical analysis, circuit simulations, and verified experimentally through measurements on prototypes implemented using discrete transistors. In this work, we propose a novel tunable negative or positive differential resistance implemented using four transistors, which offers an advantage over the conventional cross‐coupled differential pair. The advantage being that the equivalent resistance exhibited by the circuit can be tuned to be either negative or positive through a tail current as well as via a bias voltage. Its linearity and range of operation are examined, and applications to oscillators are demonstrated through simulations and experiments. [ABSTRACT FROM AUTHOR]

This paper reports the analyses of the inductive degeneration, noise filter, and optimum current density techniques for phase noise reduction in the CMOS Hartley oscillator circuit topology. The design of the circuit topology is carried out in 28 nm bulk CMOS technology in a range of common conditions adopted also for a previous study on the Colpitts topology, so complementing the previous study on Colpitts topology and allowing a direct comparison between the Hartley and Colpitts topologies. The theoretical analyses of the three techniques are carried out and verified by means of circuit simulations. The results obtained for the inductive degeneration and noise filter show the existence of an optimum inductance for minimum phase noise. Moreover, the results obtained for the optimum bias current density technique applied to a Hartley oscillator circuit topology incorporating either inductive degeneration or noise filter provide the demonstration of the existence of an optimum bias current density for minimum phase noise. Moreover, we will go beyond this important result, by investigating for the first time the relationship with the optimum current density for transistor minimum noise figure and other general results reported in the literature. Overall, the analyses show that the adoption of these techniques may lead to a potential phase noise reduction up to 16 dB at a 1 MHz frequency offset for an oscillation frequency of 10 GHz, with respect to the traditional Hartley topology. Lastly, we report a comparison under common conditions between Colpitts and Hartley topologies implementing the aforementioned techniques, which could, from a designer perspective, be useful to acquiring a few key insights about the circuit design opportunities and focus the design efforts toward specific directions for performance optimizations.

A 50 GHz cross-coupled differential-pair oscillator with a high-Q active inductor in the LC tank has been designed and fabricated in 65 nm bulk complementary metal-oxide semiconductor (CMOS) technology. The principle of operation is explained and a complete theoretical study is carried out. The analytical expressions for the open loop transfer function, oscillation frequency, start-up condition, tank impedance, and phase noise are derived. The results of the analytical study are compared with those obtained by SpectreRF simulations in the Cadence design environment. Measurement results of the stand-alone mm-wave active inductor show an equivalent inductance of 133 pH with a quality factor exceeding 400 at 50 GHz, demonstrating experimentally the implementation of high-Q active inductors operating at the millimeter waves in CMOS technology. The measurement results of the oscillator show a phase noise of −85 dBc/Hz at 1 MHz frequency offset from the carrier when the active inductor is switched off and −91 dBc/Hz when it is switched on, leading to a phased noise reduction of 6 dB.

This paper reports a novel oscillator circuit topology based on a transformer-coupled p-network. As a case study, the proposed oscillator topology has been designed and studied for 60 GHz applications in the frame of the emerging fifth generation wireless communications. The analytical expression of the oscillation frequency is derived and validated through circuit simulations. The root-locus analysis shows that oscillations occur only at that resonant frequency of the LC tank. Moreover, a closed-form expression for the quality factor (Q) of the LC tank is derived which shows the enhancement of the equivalent quality factor of the LC tank due to the transformer-coupling. Last, a phase noise analysis is reported and the analytical expressions of phase noise due to flicker and thermal noise sources are derived and validated by the results obtained through SpectreRF simulations in the Cadence design environment with a 28 nm CMOS process design kit commercially available.

Pancreatic cancer is an aggressive cancer of the digestive system, which is becoming a serious health problem worldwide. Overall survival for patients with pancreatic cancer is poor, mainly due to a lack of biomarkers to enable early diagnosis and a lack of prognostic markers that can inform decision-making, facilitating personalized treatment and an optimal clinical outcome. ncRNAs play an important role in pancreatic carcinogenesis. Here we review the literature on the role of ncRNAs as biomarkers in pancreatic cancer. We focus on the significance of ncRNAs as markers for early diagnosis, as prognostic biomarkers able to inform clinical management and as targets for novel therapeutics for patients with pancreatic cancer.

Single nucleotide polymorphisms (SNPs) in microRNA genes have been associated with colorectal cancer (CRC) risk, survival and response to treatment. Conflicting results are available on the association between rs4919510, a SNP in mature miR-608 and clinical outcome in CRC. Here, we analyzed the association between rs4919510 and benefit from perioperative treatment in a randomised phase II trial of neoadjuvant Capecitabine and Oxaliplatin (CAPOX) followed by chemo-radiotherapy, surgery and adjuvant CAPOX ± Cetuximab in high-risk locally advanced rectal cancer (LARC). A total of 155/164 (94.5%) patients were assessable. 95 (61.3%) were homozygous for CC, 55 (35.5%) heterozygous (CG) and 5 (3.2%) homozygous for GG. Median follow-up was 64.9 months. In the CAPOX arm the 5-year progression-free survival (PFS) and overall survival (OS) rates were 54.6% and 60.7% for CC and 82.0% and 82.1% for CG/GG, respectively (HR PFS 0.13, 95% CI: 0.12-0.83, P = 0.02; HR OS 0.38, 95% CI: 0.14-1.01, P = 0.05). In the CAPOX-C arm PFS and OS were 73.2 and 82.2%, respectively for CC carriers and 64.6 and 73.1% for CG/GG carriers (HR PFS 1.38, 95% CI: 0.61-3.13, P = 0.44; HR OS 1.34, 95% CI: 0.52-3.48, P = 0.55). An interaction was found between study treatment and rs4919510 genotype for both PFS (P = 0.02) and OS (P = 0.07). This is the first study investigating rs4919510 in LARC. The CC genotype appeared to be associated with worse prognosis compared to the CG/GG genotype in patients treated with chemotherapy and chemo-radiotherapy alone. Addition of Cetuximab to chemotherapy and chemo-radiotherapy in CC carriers appeared to improve clinical outcome. [ABSTRACT FROM AUTHOR]

This paper reports the analyses of three techniques for phase noise reduction in the complementary metal-oxide semiconductor (CMOS) Colpitts oscillator circuit topology. Namely, the three techniques are inductive degeneration, noise filter, and optimum current density. The design of the circuit topology is carried out in 28-nm bulk CMOS technology. The analytical expression of the oscillation frequency is derived and validated through circuit simulations. Moreover, the theoretical analyses of the three techniques are carried out and verified by means of circuit simulations within a commercial design environment.

Overall, the analyses show that the adoption of these techniques may lead to a potential phase noise reduction up to 19 dB at a 1-MHz frequency offset for an oscillation frequency of 10 GHz. © 2015 The Authors International Journal of Circuit Theory and Applications Published by John Wiley & Sons Ltd.

This paper addresses the extension of the on-chip cold-source noise figure (NF) measurement methodology to millimeter-wave (mm-wave) integrated circuits by using the PNA-X. The proposed methodology has been successfully applied to the on-chip NF measurements of mm-wave building blocks on silicon such as a 4-b programmable 16-phase active phase shifter. The results show how the cold-source method can be extended up to the mm-wave frequency range by using the PNA-X with frequency extenders and an active frequency down-converter, so allowing satisfactory NF measurements of mm-wave integrated circuits.

The potential of active inductors (AIs) has been often reduced by lack of accurate design methodologies and limitations due to the inherent noise sources. This paper deals with these two open issues for a high-frequency CMOS AI characterized by high-quality factor, low-power consumption, and low noise. First, it reports an effective design methodology for the implementation of high-frequency CMOS AIs with a high-quality factor. In particular, it shows how, through an advanced small-signal circuit model, to carry out an accurate and reliable design at high frequency (over 10 GHz) in modern nanoscale CMOS process. The design methodology is validated through cases of study at 13 GHz implemented in a standard 90-nm CMOS process and characterized experimentally. The results show that the AI exhibits an equivalent inductance close to 3.2 nH with an associated quality factor close to 200. After, it reports a noise analysis. It shows that the AI exhibits a very low level of noise, enabling its application to the implementation of high-quality factor low-noise LC tank in high-frequency building blocks of radio frequency front-ends. The results show that the AI exhibits a noise power spectral density lower than −150 dBm/Hz. [ABSTRACT FROM AUTHOR]

This paper presents three practical antenna implementations based on variations of one general planar differential antenna topology originally proposed for ultrawideband (UWB) applications. All designs were implemented on a low-cost FR4 substrate and experimentally characterized in an anechoic chamber. The results show how the proposed design variations lead to the required antenna performances and how they give rise to new opportunities in terms of coverage of wide, narrow, and multiple frequency bands for communication and sensing applications below 5 GHz. In particular, the results show how a significant enhancement in bandwidth performance is achieved by folding the differential radiating elements. Moreover, they show how an agile design strategy enables adaption of the antenna design to different requirements for covering wide, narrow, and multiple bands, making the proposed class of antennas suitable for different wireless applications. In detail, the proposed class of antennas covers multiple frequency bands, ranging from the 868 MHz and 915 MHz bands to 2.4 GHz industrial scientific and medical (ISM) bands, including the 1.2 GHz L band for Global Positioning and Navigation Satellite Systems (GNSS) and the lower portion of the UWB band.

Comparative Phase Noise analyses of common-source cross-coupled pair, Colpitts, Hartley and Armstrong differential oscillator circuit topologies, designed in 28 nm bulk CMOS technology in a set of common conditions for operating frequencies in the range from 1 GHz to 100 GHz, are carried out in order to identify their relative performance. The impulse sensitivity function (ISF) is used to carry out qualitative and quantitative analyses of the noise contributions exhibited by each circuit component in each topology, allowing an understanding of their impact on phase noise. The comparative analyses show the existence of five distinct frequency regions in which the four topologies rank unevenly in terms of best phase noise performance. Moreover, the results obtained from the ISF show the impact of flicker noise contribution as the major effect leading to phase noise degradation in nanoscale CMOS LC oscillators.

Introduction The two isoforms of estrogen receptor (ER) alpha and beta play opposite roles in regulating proliferation and differentiation of breast cancers, with ER-alpha mediating mitogenic effects and ER-beta acting as a tumor suppressor. Emerging data have reported that androgen receptor (AR) activation inhibits ER-positive breast cancer progression mainly by antagonizing ER-alpha signaling. However, to date no studies have specifically evaluated a potential involvement of ER-beta in the inhibitory effects of androgens. Methods ER-beta expression was examined in human breast cancer cell lines using real-time PCR, Western blotting and small interfering RNA (siRNA) assays. Mutagenesis studies, electromobility shift assay (EMSA) and chromatin immunoprecipitation (ChIP) analysis were performed to assess the effects of mibolerone/AR on ER-beta promoter activity and binding. Results In this study, we demonstrate that mibolerone, a synthetic androgen ligand, up-regulates ERbeta mRNA and protein levels in ER-positive breast cancer cells. Transient transfection experiments, using a vector containing the human ER-beta promoter region, show that mibolerone increases basal ER-beta promoter activity. Site-directed mutagenesis and deletion analysis reveal that an androgen response element (ARE), TGTTCT motif located at positions -383 and -377, is critical for mibolerone-induced ER-beta up-regulation in breast cancer cells. This occurs through an increased recruitment of AR to the ARE site within the ER-beta promoter region, along with an enhanced occupancy of RNA polymerase II. Finally, silencing of ER-beta gene expression by RNA interference is able to partially reverse the effects of mibolerone on cell proliferation, p21 and cyclin D1 expression. Conclusions Collectively, these data provide evidence for a novel mechanism by which activated AR, through an up-regulation of ER-beta gene expression, inhibits breast cancer cell growth.

The design of modern radiofrequency integrated circuits on silicon operating at microwave and millimeterwaves requires the integration of several spiral inductors and transformers that are not commonly available in the process design-kits of the technologies. In this work we present an auxiliary CAD tool for Microwave Inductor (and transformer) Design Automation on Silicon (MIDAS) that exploits commercial simulators and allows the implementation of an automatic design flow, including threedimensional layout editing and electromagnetic simulations. In detail, MIDAS allows the designer to derive a preliminary sizing of the inductor (transformer) on the bases of the design entries (specifications). It draws the inductor (transformer) layers for the specific process design kit, including vias and underpasses, with or without patterned ground shield, and launches the electromagnetic simulations, achieving effective design automation with respect to the traditional design flow for RFICs. With the present software suite the complete design time is reduced significantly (typically 1 hour on a PC based on Intel® Pentium® Dual 1.80 GHz CPU with 2-GB RAM). Afterwards both the device equivalent circuit and the layout are ready to be imported in the Cadence environment. [ABSTRACT FROM AUTHOR]

This paper reports the latest advances on millimeter-wave CMOS voltage-controlled oscillators (VCOs). Current state-of-the-art implementations are reviewed, and their performances are compared in terms of phase noise and figure of merit. Low power and low phase noise LC-VCO and ring oscillator designs are analyzed and discussed. Design and performance trends over the last decade are provided and discussed. The paper shows how for the higher range of millimeter-waves (>60GHz) the performances of ring oscillators become comparable with those of LC-VCOs. [ABSTRACT FROM AUTHOR]

Applying pulsewidth modulation (PWM) to control the gain in audio codecs for mobile applications leads to several advantages, such as the smooth control of tuning parameters, smaller silicon area, and lower power consumption, as compared with other tuning techniques using programmable gain amplifiers and zero crossing detectors. The PWM has to be embedded into the main signal path, preferably in a closed-loop control scheme, in order to exploit its benefits. However, the insertion of dithering and offset controls in a gain setting loop poses the problem of controlling their effects in all gain conditions. This paper reports a novel technique aimed at solving the associated issues and limitations, and provides the experimental proof of the concept through the implementation of a test-chip design on silicon. In particular, this paper reports the design and experimental results of a delta–sigma analog-to-digital converter featuring a click-free gain control technique, dithering insertion, and idle-tone shifting, which has been implemented in a 40-nm complementary metal–oxide–semiconductor technology for commercial telecom audio codec applications.

Aberrant changes in microRNA expression contribute to lymphomagenesis. Bromodomain and extra-terminal domain inhibitors such as OTX015 (MK-8628, birabresib) have demonstrated preclinical and clinical activity in hematologic tumors. MicroRNA profiling of diffuse large B-cell lymphoma cells treated with OTX015 revealed changes in the expression levels of a limited number of microRNAs, including miR-92a-1-5p, miR-21-3p, miR-155-5p and miR-96-5p. Analysis of publicly available chromatin immunoprecipitation sequencing data of diffuse large B-cell lymphoma cells treated with bromodomain and extra-terminal domain (BET) inhibitors showed that the BET family member BRD4 bound to the upstream regulatory regions of multiple microRNA genes and that this binding decreased following BET inhibition. Alignment of our microRNA profiling data with the BRD4 chromatin immunoprecipitation sequencing data revealed that microRNAs downregulated by OTX015 also exhibited reduced BRD4 binding in their promoter regions following treatment with another bromodomain and extra-terminal domain inhibitor, JQ1, indicating that BRD4 contributes directly to microRNA expression in lymphoma. Treatment with bromodomain and extra-terminal domain inhibitors also decreased the expression of the arginine methyltransferase PRMT5, which plays a crucial role in B-cell transformation and negatively modulates the transcription of miR-96-5p. The data presented here indicate that in addition to previously observed effects on the expression of coding genes, bromodomain and extra-terminal domain inhibitors also modulate the expression of microRNAs involved in lymphomagenesis., (Copyright© 2018 Ferrata Storti Foundation.)
