Recent advances in myeloid-derived suppressor cell biology

Mahmoud Mohammad Yaseen, Nizar Mohammad Abuharfeil, Homa Darmani, Ammar Daoud

Frontiers of Medicine 2021, Volume 15, Issue 2,   Pages 232-251 doi: 10.1007/s11684-020-0797-2

Abstract: In recent years, studying the role of myeloid-derived suppressor cells (MDSCs) in many pathological inflammatory conditions has become a very active research area. Although the role of MDSCs in cancer is relatively well established, their role in non-cancerous pathological conditions remains in its infancy resulting in much confusion. Our objectives in this review are to address some recent advances in MDSC research in order to minimize such confusion and to provide an insight into their function in the context of other diseases. The following topics will be specifically focused upon: (1) definition and characterization of MDSCs; (2) whether all MDSC populations consist of immature cells; (3) technical issues in MDSC isolation, estimation and characterization; (4) the origin of MDSCs and their anatomical distribution in health and disease; (5) mediators of MDSC expansion and accumulation; (6) factors that determine the expansion of one MDSC population over the other; (7) the Yin and Yang roles of MDSCs. Moreover, the functions of MDSCs will be addressed throughout the text.

Abstract: Designing logic circuits using complementary metal-oxide-semiconductor (CMOS) technology at the nano scale has been faced with various challenges recently. Undesirable leakage currents, the short-effect channel, and high energy dissipation are some of the concerns. represent an appropriate alternative for possible CMOS replacement in the future because it consumes an insignificant amount of energy compared to the standard CMOS. The key point of designing arithmetic circuits is based on the structure of a 1-bit . A low-complexity block is beneficial for developing various intricate structures. This paper represents scalable 1-bit QCA structures based on cell interaction. Our proposed s encompass preference aspects of QCA design, such as a low number of cells used, low latency, and small area occupation. Also, the proposed structures have been expanded to larger circuits, including a 4-bit , a 4-bit ripple borrow subtractor (RBS), an , and a 2-bit array . All designs were simulated and verified using QCA Designer-E version 2.2. This tool can estimate the energy dissipation as well as evaluate the performance of the circuits. Simulation results showed that the proposed designs are efficient in complexity, area, latency, cost, and energy dissipation.

Abstract: New technologies such as have been showing some remarkable characteristics that standard complementary-metal-oxide semiconductor (CMOS) in deep sub-micron cannot afford. Modeling systems and designing multiple-valued logic gates with QCA have advantages that facilitate the design of complicated logic circuits. In this paper, we propose a novel creative concept for . The concept has been set in , the new simulator developed by our team exclusively for QCAs’ quaternary mode. Proposed basic gates such as MIN, MAX, and different types of inverters (SQI, PQI, NQI, and IQI) have been designed and verified by . This study will exemplify how fast and accurately works by its handy set of CAD tools. A 1×4 decoder is presented using our proposed main gates. Preference points such as the minimum delay, area, and complexity have been achieved in this work. QQCA main logic gates are compared with based on carbon nanotube field-effect transistor (CNFET). The results show that the proposed design is more efficient in terms of latency and energy consumption.

Spin polarization strategy to deploy proton resource over atomic-level metal sites for highly selective CO electrolysis

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 12,   Pages 1772-1781 doi: 10.1007/s11705-022-2197-4

Abstract: Unlocking of the extremely inert C=O bond during electrochemical CO2 reduction demands subtle regulation on a key “resource”, protons, necessary for intermediate conversion but also readily trapped in water splitting, which is still challenging for developing efficient single-atom catalysts limited by their structural simplicity usually incompetent to handle this task. Incorporation of extra functional units should be viable. Herein, a proton deployment strategy is demonstrated via “atomic and nanostructured iron (A/N-Fe) pairs”, comprising atomically dispersed iron active centers spin-polarized by nanostructured iron carbide ferromagnets, to boost the critical protonation steps. The as-designed catalyst displays a broad window (300 mV) for CO selectivity > 90% (98% maximum), even outperforming numerous cutting-edge M–N–C systems. The well-placed control of proton dynamics by A/N-Fe can promote *COOH/*CO formation and simultaneously suppress H2 evolution, benefiting from the magnetic-proximity-induced exchange splitting (spin polarization) that properly adjusts energy levels of the Fe sites’ d-shells, and further those of the adsorbed intermediates’ antibonding molecular orbitals.

An improved Merkle hash tree based secure scheme for bionic underwater acoustic communication Research Articles

Masoud Kaveh, Abolfazl Falahati,afalahati@iust.ac.ir

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 7,   Pages 1010-1019 doi: 10.1631/FITEE.2000043

Abstract: Recently, bionic signals have been used to achieve covert underwater acoustic communication (UWAC) with high signal-to-noise ratios (SNRs) over transmission systems. A high SNR allows the attackers to proceed with their mischievous goals and makes transmission systems vulnerable against malicious attacks. In this paper we propose an based secure scheme that can resist current underwater attacks, i.e., replay attack, fabricated message attack, message-altering attack, and analyst attack. Security analysis is performed to prove that the proposed scheme can resist these types of attacks. Performance evaluations show that the proposed scheme can meet UWAC limitations due to its efficiency regarding energy consumption, communication overhead, and computation cost.

Dynamic power-gating for leakage power reduction in FPGAs Research Article

Hadi JAHANIRAD,h.jahanirad@uok.ac.ir

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 4,   Pages 582-598 doi: 10.1631/FITEE.2200084

Abstract: devices have become widespread in electronic systems due to their low design costs and reconfigurability. In battery-restricted applications such as handheld electronics systems, low-power FPGAs are in great demand. almost equals dynamic power in modern integrated circuit technologies, so the reduction of leads to significant energy savings. We propose a power-efficient architecture for static random access memory (SRAM) based FPGAs, in which two modes (active mode and sleep mode) are defined for each module. In sleep mode, ultra-low is consumed by the module. The module mode changes dynamically from sleep mode to active mode when module outputs evaluate for new input vectors. After producing the correct outputs, the module returns to sleep mode. The proposed circuit design reduces the consumption in both active and sleep modes. The proposed low-leakage FPGA architecture is compared with state-of-the-art architectures by implementing Microelectronics Center of North Carolina (MCNC) benchmark circuits on FPGA-SPICE software. Simulation results show an approximately 95% reduction in consumption in sleep mode. Moreover, the total power consumption (leakage+dynamic power consumption) is reduced by more than 15% compared with that of the best previous design. The average area overhead (4.26%) is less than those of other designs.
