Abstract:

Four monolithic current-mode instrumentation amplifier (in-amp) topologies implemented in a standard 0.25µm complementary metal-oxide semiconductor (CMOS) process, with positive second-generation current conveyors (CCII+) as building blocks are presented in this paper.  The in-amp topologies are designed to handle biomedical signals, specifically that of the electrocardiogram (ECG). Four types of CCII+ are characterized and realized using a rail-to-rail operational amplifier (op-amp) and different types of current mirrors.  The Op-Amp with Simple Current Mirror exhibits the hig

Abstract:

In this paper, we introduce an implementation of a CCII-based grounded inductance operating in class AB. In order to get tunable characteristics of the design, a translinear CCII configuration is used as a basic block for its high level of controllability. A frequency characterization of the translinear CCII is done. In order to optimize its static and dynamic characteristics, an algorithmic driven methodology is developed ending to the optimal transistor geometries. The optimized CCII has a current bandwidth of 1.28 GHz and a voltage bandwidth of 5.48 GHz. It is applied in the simulated induc

The realization of the Tow–Thomas (TT) circuit using the Operational Transresistance Amplifier (OTRA) is reviewed.

The progress in the realization of the TT circuit using CCII is demonstrated clearly by summarizing eight different circuits.

Abstract:

In this study, a review of second-generation voltage conveyor (VCII) and current conveyor (CCII) circuits for the conditioning of bio signals and sensors is presented. The CCII is the most known current-mode active block, able to overcome some of the limitations of the classical operational amplifier, which provides an output current instead of a voltage. The VCII is nothing more than the dual of the CCII, and for this reason it enjoys almost all the properties of the CCII but also provides an easy-to-read voltage as an output signal.

A five-port general-purpose analog building block, termed as an Operational Floating Current Conveyor (OFCC), is described. The OFCC combines the features of current feedback operational amplifier, second-generation current conveyor and operational floating conveyor.

Although the adjoint network theorem preserves all the circuit properties it does not, however, guarantee that the floating property of an element is maintained. In other words, the adjoint of a floating element may not be floating and vice-versa a nonfloating element may have an adjoint floating element as will be explained in this paper. An important and new property of the Nodal Admittance Matrix (NAM) is that it can identify any element as a floating or nonfloating.

Abstract:

In multiuser MIMO uplink communications, it is necessary to design linear schemes that are able to suppress co-channel interferences (CCIs). In this paper, we propose a linear block QR decomposition (BQRD) which transforms the multiuser channel to a block upper triangular structure based on Gram-Schmidt orthonormalization and can obtain more diversity gain than traditional BD. And a optimal ordering criterion is proposed at last to do full study of BQRD scheme. Simulation results show that the BQRD with the optimal ordering proposed achieves much better performance than the non-ordering one.

Purpose Level 1 evidence supports the use of neoadjuvant chemotherapy (NAC) for the treatment of muscle-invasive bladder cancer (MIBC), but observational data demonstrate that this approach is underused. A barrier to shared decision making is difficulty in predicting and communicating survival estimates after cystectomy with or without NAC. Methods We included patients with MIBC from the National Cancer Database treated with cystectomy. A state-transition model was constructed for calculating 5-year death risk using baseline patient-, tumor-, and facility-level variables. Internal-external cro

Abstract Abstract 3131 Objective: To assess treatment responses and prognostic indicators of response among patients with chronic myeloid leukemia (CML) in multiple countries. Methods: Physicians in United States (N=60), United Kingdom (N=45), Germany (N=49), and Japan (N=60) were recruited to abstract data retrospectively from medical records of patients diagnosed with CML between 1/1/2005 and 12/31/2009. Patients selected were age ≥18 years and in chronic phase at the time of diagnosis and were Philadelphia chromosome and/or BCR-ABL positive. Patients were also required to have received 1st-

Abstract:

Abstract Background: Obese-driven liver cancer (HCC) is alarmingly rising in the US. Yet, key signaling mechanisms underlying this obesity-driven HCC remain unclear. SIRT6 is a NAD+-dependent deacetylase that limits the activity of the lipogenic transcription factors SREBP1/2 and TGF-β signaling. Reduced SIRT6 is associated with human fatty liver and HCC. We found that TGF-β/SMAD3 signaling pathway and SREBP1/2 are modulated by βII-spectrin (encoded by SPTBN1), and a mutation in human HCC, D1089Y abrogates SMAD3 binding (Gastro 2018; 154:195-210). In stressed hepatocytes, βII-spectrin promotes

Abstract:

Dyslipidemias are one of the risk factors for cardiovascular diseases, the leading cause of death and hospitalization worldwide. One way to control cholesterol levels is to control the exogenous cholesterol intake in the body. Natural polyphenolic compounds, namely theaflavins from plant extracts such as black tea, showed the ability to inhibit the formation of the micellar structure, essential for the absorption of cholesterol in the intestine. There are several methodologies to determine this effect, many of which are expensive and time-consuming. Due to these facts, the main purposes of thi

Abstract:

Abstract Accurate and timely segmentation of COVID-19 infection regions is critical for effective diagnosis and treatment. While convolutional neural networks (CNNs) exhibit strong performance in medical image segmentation, they face challenges in handling complex lesion morphologies with irregular boundaries. Transformer-based approaches, though demonstrating superior capability in capturing global context, suffer from high computational costs and suboptimal multi-scale feature integration. To address these limitations, we proposed Hierarchical Agent Transformer Network (HATNet), a hierarchic
