—This paper reports a CMOS terahertz oscillator with a novel frequency selective negative resistance (FSNR) tank to boost its operating frequency. The demonstrated oscillator can operate at a fundamental frequency of about 0.22 THz, exceeding the CMOS device cutoff frequency of f T. The proposed architecture suppresses undesired 2nd and odd harmonics and(More)
Bisphenol A (BPA), a synthetic additive used to harden polycarbonate plastics and epoxy resin, is ubiquitous in our everyday environment. Many studies have indicated detrimental effects of BPA on the mammalian reproductive abilities. This study is aimed to test the potential effects of BPA on methylation of imprinted genes during oocyte growth and meiotic(More)
—A single-feed circular microstrip antenna with recon-figurable polarization capability is proposed. This antenna has a simple structure, which consists of a radiating circular patch, five switches (PIN diode), three matching stubs, and a 50 microstrip feed line. It can be switched between 4 different states: two states (low-frequency and high-frequency)(More)
Bisphenol A (BPA) is an estrogenic environmental toxin widely used for the production of plastics. Frequent human exposure to this chemical has been proposed to be a potential public health risk. The objective of this study was to assess the effects of BPA on germ cell cyst breakdown and primordial follicle formation. Pregnant mice were treated with BPA at(More)

— A W-band CPW-fed 3-D quarter-wavelength monopole that is vertically mounted on a variety of substrates is reported for the first time. A transition from coplanar waveguide to vertical coaxial structure is investigated. The structure demonstrates broadband impedance matching and symmetry radiation pattern in W-band. Greater than 10 dB return loss over 19(More)
—A new low-profile broadband dual-frequency planar antenna is developed for wireless handsets. The dual-frequency antenna consists of a two-strip monopole for the 2-GHz band and a planar monopole for the 5-GHz band. The developed antenna features a low profile due to the introduction of an S-strip and a T-strip which are separately printed on the two sides(More)
1 signalling and antipsychotic treatment: potential therapeutic targets in a schizophrenia candidate signalling pathway', Psychopharmacology, vol. 226, no. 2, pp. 201-215. Abstract Identifying the signalling pathways underlying the pathophysiology of schizophrenia is an essential step in the rational development of new antipsychotic drugs for this(More)

—In this letter, a 3-D high-quality-factor millimeter-wave cavity resonator is integrated on the lossy soda-lime glass substrate utilizing surface micromachining technologies. With a height of 300 m, the air-lifted cavity features a measured of at least 219 at 30 GHz, demonstrating an improvement by almost an order of magnitude with respect to respective(More)
The oncogene Akt1 plays a pivotal role in regulating growth factor-associated cell survival. The activity of Akt must be carefully regulated as it has been reported that an increase in Akt signaling is frequently associated with cancer. Phosphorylated Akt, as the constitutively activated form of Akt, has been observed in many kinds of cancer, but the(More)
