A fully integrated 4× 4 802.11abgn/ac/ax transceiver system-on-chip (SoC) with integrated interference analyzer and frequency-dependent in-phase and quadrature (IQ) (FD-IQ) calibration is presented. The FD-IQ technique helps meeting the extremely strict IQ imbalance requirement for 1-K quadratic-amplitude modulation (QAM). The pure current-mode TX baseband (BB) improves SNR to better than 50 dB, and a multi-mode local oscillator (LO) distribution circuit provides non-contiguous operation with the error vector magnitude (EVM) of less than -37 dB. The integrated interference analyzer achieves the highly reliable connection in the presence of the undesired signal and hence improves the frequency usage efficiency by identifying the wireless LAN (WLAN) and other signals in the 2G/5G band.
Human Urine-Derived Stem Cell Differentiation to Endothelial Cells with Barrier Function and Nitric Oxide Production (2018)

Endothelial cells (ECs) play a key role in revascularization within regenerating tissue. Stem cells are often used as an alternative cell source when ECs are not available. Several cell types have been used to give rise to ECs, such as umbilical cord vessels, or differentiated from somatic stem cells, embryonic, or induced pluripotent stem cells. However, the latter carry the potential risk of chronic immune rejection and oncogenesis. Autologous endothelial precursors are an ideal resource, but currently require an invasive procedure to obtain them from the patient's own blood vessels or bone marrow. Thus, the goal of this study was to determine whether urine-derived stem cells (USCs) could differentiate into functional ECs in vitro. Urine-derived cells were then differentiated into cells of the endothelial lineage using endothelial differentiation medium for 14 days. Changes in morphology and ultrastructure, and functional endothelial marker expression were assessed in the induced USCs in vitro. Grafts of the differentiated USCs were then subcutaneously injected into nude mice. Induced USCs expressed significantly higher levels of specific markers of ECs (CD31, vWF, eNOS) in vitro and in vivo, compared to nondifferentiated USCs. In addition, the differentiated USC formed intricate tubular networks and presented similar tight junctions, and migration and invasion ability, as well as ability to produce nitric oxide (NO) compared to controls. Using USCs as autologous EC sources for vessel, tissue engineering strategies can yield a sufficient number of cells via a noninvasive, simple, and low-cost method suitable for rapid clinical translation.

Implementation and Evaluation of a Stator and Rotor Flux Linkage-Based Dead-Beat, Direct Torque Control of Induction Machines at the Operational Voltage Limits (2007)

Dead-beat, direct torque (and flux) control of an induction machine is experimentally achieved at a 10 kHz sampling frequency. The inverse solution utilized lends itself to a very insightful graphical representation. This allows for an objective experimental evaluation of voltage vector choices in the operational voltage limits. The parameter sensitivity of the control algorithm is also investigated.
Effects of Different Stabilizers on Miniemulsion Methyl Methacrylate Polymerizations (2020)

Abstract The present work evaluated the effects of different ionic and nonionic stabilizers and respective concentrations on methyl methacrylate (MMA) miniemulsion polymerizations. The stabilities of the prepared miniemulsions are characterized through sedimentation and phase separation analyses and afterwards polymerizations are performed at the most stable conditions for each analyzed stabilizer. Monomer conversion profiles and final product properties are determined for comparative purposes. Obtained results indicated that the performances of the stabilizers during the polymerizations are not necessarily related to the stabilizing performances observed during preparation of the miniemulsions and that polymer latexes produced with the nonionic surfactant Tween80 presented the most suitable properties for applications in the biomedical field, as this stabilizer presented good stabilizing performances both during miniemulsion preparation and miniemulsion polymerization.
Aptamers and apple pies: a mini-review of PSMA aptamers and lessons from Donald S. Coffey. (2018)

This mini-review article is part of a special issue dedicated to Donald S. Coffey, a pioneer translational research scientist, exemplary mentor, and leader in urologic and urologic oncology research. This article first briefly reflects on life and scientific lessons from Don Coffey. It then reviews the development of two prostate cancer targeting RNA aptamers, xPSM-A9 and xPSM-A10, through <i>in vitro</i> selection for aptamers that bind to the extracellular domain of the Prostate Specific Membrane Antigen (PSMA). These 2'-fluorpyrimidine RNA aptamers selectively bind PSMA on the surface of prostate cancer cells, inhibit PSMA glutamate carboxypeptidase activity, and internalize into PSMA-expressing cancer cells. The truncation of both aptamers, through experimentation as well as logical design, has produced smaller isoforms including A10-3, A10-3.2, A9g and A9L. The larger aptamer isoforms xPSM-A9 and xPSM-A10 are limited to production by <i>in vitro</i> transcription and polyacrylamide gel purification, while smaller isoforms can be generated by chemically synthesis. A series of aptamer conjugates have been developed through chemical crosslinking, complementary annealing strategies, or a combination of both, for the targeting of experimental therapeutics to and into prostate cancer cells. The resulting aptamer conjugates, including nanoparticles and siRNA conjugates, selectively target PSMA-positive prostate cancer cells and xenograft tumors, and demonstrate potent cytotoxic and tumoricidal activity. These experimental therapeutic agents provide a platform for realizing and optimizing the potential of tumor-selective targeting and drug delivery.
Dynamic Metasurface Antennas for 6G Extreme Massive MIMO Communications (2021)

Next generation wireless base stations and access points will transmit and receive using an extremely massive numbers of antennas. A promising technology for realizing such massive arrays in a dynamically controllable and scalable manner with reduced cost and power consumption utilizes surfaces of radiating metamaterial elements, known as metasurfaces. To date, metasurfaces are mainly considered in the context of wireless communications as passive reflecting devices, aiding conventional transceivers in shaping the propagation environment. This article presents an alternative application of metasurfaces for wireless communications as active reconfigurable antennas with advanced analog signal processing capabilities for next generation transceivers. We review the main characteristics of metasurfaces used for radiation and reception, and analyze their main advantages as well as their capability to reliably communicate in wireless networks. As current studies unveil only a portion of the potential of metasurfaces, we detail a list of exciting research and implementation challenges which arise from the application of metasurface antennas for wireless transceivers.

Partitioned List Decoding of Polar Codes: Analysis and Improvement of\n Finite Length Performance (2017)

Polar codes represent one of the major recent breakthroughs in coding theory\nand, because of their attractive features, they have been selected for the\nincoming 5G standard. As such, a lot of attention has been devoted to the\ndevelopment of decoding algorithms with good error performance and efficient\nhardware implementation. One of the leading candidates in this regard is\nrepresented by successive-cancellation list (SCL) decoding. However, its\nhardware implementation requires a large amount of memory. Recently, a\npartitioned SCL (PSCL) decoder has been proposed to significantly reduce the\nmemory consumption. In this paper, we examine the paradigm of PSCL decoding\nfrom both theoretical and practical standpoints: (i) by changing the\nconstruction of the code, we are able to improve the performance at no\nadditional computational, latency or memory cost, (ii) we present an optimal\nscheme to allocate cyclic redundancy checks (CRCs), and (iii) we provide an\nupper bound on the list size that allows MAP performance.\n
Abstract 1551: GULP1 is an epigenetically altered and functional tumor suppressor in urothelial carcinoma through regulation of Nrf2-Keap1 signaling axis (2017)

Abstract We identified GULP1 as a novel tumor suppressor gene (TSG) selectively silenced during urothelial cancer (UC) progression through promoter hypermethylation (PH) analyzed by quantitative methylation specific PCR (QMSP) and novel methylation specific digital droplet PCR (ddPCR) assay. Numerous cell based assays revealed that GULP1 silencing confers growth advantage to tumor cells. Correspondently, in vivo tumorigenicity after xenotransplantation of GULP1 knockdown T24 cells was significantly higher than control cells. Further mechanistic analysis revealed that GULP1 has a crucial role in the regulation of Nrf2-Keap1 axis, maintaining actin cytoskeleton architecture and helping Keap1 to scaffold Nrf2 in the cytoplasm. Moreover, GULP1 silencing induces constitutive activation of Nrf2 target signature, responsible for chemoresistance of UCs. Additionally, we analyzed GULP1 PH and expression in cisplatin-based therapy responsive and resistant primary UC samples, and in isogenic cisplatin sensitive and resistant T24 cell lines. Interestingly, GULP1 expression at transcription level was lower in both resistant primary UC samples and resistant T24 cell line. Cell lines with lower expressions of GULP1 (SW780 and UM-UC-3) also showed higher resistance to cisplatin than those with higher expression (T24 and BFTC905). Altogether, our findings determined that GULP1 is an epigenetically silenced potential TSG in UC and GULP1 expression and/or PH may guide in selecting candidate patients for cisplatin based neo-adjuvant therapy.

TSH and Bone Loss (2006)

We have recently challenged the view that the bone loss associated with hyperthyroidism is solely due to elevated thyroid hormone levels. We find that thyroid-stimulating hormone (TSH), derived from the anterior pituitary gland, inhibits bone resorption by the osteoclast. Mice haploinsufficient in the TSH receptor show reduced bone density and evidence of enhanced bone resorption in the face of normal thyroid function. In humans, TSH inhibits markers of bone resorption with a single administration, and low TSH levels correlate with increased fracture risk. The evidence that low TSH levels predispose to osteoporosis in hyperthyroidism is discussed in view of the emerging role of pituitary hormones in bone biology.
The Effect of Age and Type of Media on Growth Kinetics of Human Amniotic Fluid Stem Cells (2020)

<b><i>Aim:</i></b> This study compared growth kinetics of human amniotic fluid stem cells (hAFSCs) in different maternal age groups and two different media of AmnioMAX and Dulbecco's modified Eagle's medium (DMEM). <b><i>Materials and Methods:</i></b> Three milliliters of amniotic fluid (AF) was provided from 16 pregnant women who were referred for amniocentesis from 16 to 18 weeks of gestation. Mothers were divided to 20-29 (<i>n</i> = 5), 30-39 (<i>n</i> = 5) and 40-49 (<i>n</i> = 6) years old age groups. AF was immediately centrifuged and the cell pellet was cultured. Cells were characterized morphologically, by flow cytometry and for osteogenic and adipogenic inductions. Population doubling time (PDT) and growth kinetics were determined. AFSCs cultured in AmnioMAX were compared in various age groups. A comparison of growth kinetics of AFSCs cultured in AmnioMAX and DMEM from 40 to 49 years old pregnant women was undertaken. <b><i>Results:</i></b> AFSCs were adherent to culture flasks and were spindle shape, and positive for osteogenic and adipogenic inductions and for expression of CD73, CD90 and CD105 markers, but negative for CD34 and CD45. PDT among 20-29, 30-39, and 40-49 years old women was 30.9, 38.3, and 43.9 hours, respectively showing a higher cell proliferation in younger ages. When comparing AmnioMAX and DMEM, PDT was 53 and 96.9 hours, respectively denoting to a higher cell proliferation in AmnioMAX. <b><i>Conclusions:</i></b> Higher proliferation and plasticity of hAFSCs were noted in AmnioMAX and in younger mothers' samples. These findings can be added to the literature and open a new avenue in regenerative medicine, when hAFSCs are targeted for cell therapy purposes.
Effects of a nutrient-enriched water on water intake and indices of hydration in healthy domestic cats fed a dry kibble diet (2018)

OBJECTIVE To evaluate the effects of drinking nutrient-enriched water (NW) on water intake and indices of hydration in healthy domestic cats fed a dry kibble diet ad libitum. ANIMALS 18 domestic shorthair cats. PROCEDURES Group-housed cats were assigned to tap water (TW; n = 9) or NW (9) groups. All cats received TW at baseline (days -7 to -1). No changes were made to the food-water regimen for the TW group. The NW group received NW instead of TW from days 0 through 10, then received TW and NW in separate bowls (days 11 through 56). Food intake was measured through day 10; liquid consumed by drinking was measured throughout the study. Blood and urine samples were collected at predetermined times for analyses; 48-hour urine collection (days 28 through 30 or 31 through 33) was performed to assess output volume and aid endogenous creatinine-based glomerular filtration rate (GFR) determination. Data were analyzed with linear mixed-effects models. RESULTS Baseline TW and calorie intake were similar between groups. The NW treatment was significantly associated with increased liquid consumption during the treatment phase. Mean urine output was significantly higher in the NW group (15.2 mL/kg/d) than in the TW group (10.3 mL/kg/d). Mean GFR (1.75 vs 1.87 mL/min/kg, respectively) did not differ between groups. Effects of treatment and time were each significant for urine specific gravity and osmolality and urine creatinine, phosphate, and urea nitrogen concentrations, with lower values for the NW group. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that consumption of the NW can increase liquid intake and improve measures of hydration in healthy cats. These effects may offer health benefits to some cats in need of greater water consumption.

Structure of a DNA−Porphyrin Complex (1996)

We report the 2.4 A resolution X-ray structure of a complex in which a small molecule flips a base out of a DNA helical stack. The small molecule is a metalloporphyrin, CuTMPyP4 [copper(II) meso-tetra(N-methyl-4-pyridyl)porphyrin], and the DNA is a hexamer duplex, [d(CGATCG)]2. The porphyrin system, with the copper atom near the helical axis, is located within the helical stack. The porphyrin binds by normal intercalation between the C and G of 5' TCG 3' and by extruding the C of 5' CGA 3'. The DNA forms a distorted right-handed helix with only four normal cross-strand Watson-Crick base pairs. Two pyridyl rings are located in each groove of the DNA. The complex appears to be extensively stabilized by electrostatic interactions between positively charged nitrogen atoms of the pyridyl rings and negatively charged phosphate oxygen atoms of the DNA. Favorable electrostatic interactions appear to draw the porphyrin into the duplex interior, offsetting unfavorable steric clashes between the pyridyl rings and the DNA backbone. These pyridyl-backbone clashes extend the DNA along its axis and preclude formation of van der Waals stacking contacts in the interior of the complex. Stacking contacts are the primary contributor to stability of DNA. The unusual lack of van der Waals stacking contacts in the porphyrin complex destabilizes the DNA duplex and decreases the energetic cost of local melting. Thus extrusion of a base appears to be facilitated by pyridyl-DNA steric clashes.
Antiperovskite Structure with Ternary Tetrathiafulvalenium Salts: Construction, Distortion, and Antiferromagnetic Ordering (1991)

Rhombohedral distortion caused by the shape of the organic ions is found in the antiperovskite structures of all four ternary salts 1,which were obtained by electrocrystallization of the components tetrathiafulvalene (TTF),tetrabutylammonium halohexamolybdate, and tetrabutylammonium halide. The three-fold symmetry is quite apparent in the structural representation of these salts on the right. These salts show a sharp transition to an antiferromagnetic ground state between 6 and 8 K.

Though initially known for their anti-inflammatory and anti-arthritic activities through a unique 5-LO inhibition mechanism, boswellic acids have recently attained significance due to their anti-cancer properties. The phytochemistry and chemical modifications, including mechanism of action, are discussed.
Nitride semiconductors as terahertz sources based on spontaneous and piezoelectric polarization (2010)

Abstract We investigate the effects of internal polarization‐related drift and diffusion on the emitted THz radiation from m ‐plane (1 $ \bar 1 $ 00), a ‐plane (11 $ \bar 2 $ 0), and c ‐plane (0001) nitride semiconductors. Enhanced THz radiation is observed from c ‐plane InN/InGaN multiple quantum wells as compared to c ‐plane bulk InN at 800 nm excitation wavelength. THz generation in the quantum well structure is due to surface normal transport in electric fields due to the termination of spontaneous and piezoelectric polarization at the well/barrier interfaces. From high stacking fault density nonpolar GaN, we observe further enhanced THz emission as compared to stacking fault free m ‐plane GaN. THz generation from the high stacking fault density m ‐plane GaN is attributed to in‐plane transport in built‐in fields due to stacking fault‐terminated internal polarization. A similar effect is observed in m ‐plane as well as a ‐plane InN. (© 2010 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)

Extra Strengthening and Superplasticity of Ultrafine-Grained A2024 Alloy Produced by High-Pressure Sliding (2017)

In this study, the method of high-pressure sliding (HPS) was applied for grain refinement of an A2024 alloy. Sheet samples with 10–15 mm width and 100 mm length with 1 mm thickness were processed by HPS under pressures of 2–3 GPa. Microstructural observations revealed that the grain size was refined to ～200 nm. Tensile tests showed that the ultimate tensile strength reached 886 MPa with a total elongation of 7.1% and the anisotropy of samples was less developed in the HPS-processed samples. Extra strengthening was attained by aging at 423 K after HPS processing, leading to an ultimate tensile strength of 967 MPa at the peak aged condition. Superplastic elongation of more than 400% appeared when the A2024 alloy processed by HPS for 20 mm was deformed in tension at a testing temperature of 623 K with an initial strain rate of 1.0 × 10−3 s−1.
