Mice lacking the proneural transcription factor Math1 (Atoh1) lack multiple neurons of the proprioceptive and arousal systems and die shortly after birth from an apparent inability to initiate respiration. We sought to determine whether Math1 was necessary for the development of hindbrain nuclei involved in respiratory rhythm generation, such as the parafacial respiratory group/retrotrapezoid n...
We propose a new reflective twisted nematic display mode, which is called the second minimum RTN mode. This mode has a larger d∆n value compared with the first minimum RTN mode which we proposed previously. A cell gap of 7μm or larger can be used for this mode which makes the fabrication processing of this kind of reflective LCDs easier and more compatible with that of TN LCDs. The color disper...
Central congenital hypoventilation syndrome is caused by mutations of the gene that encodes the transcription factor Phox2b. The syndrome is characterized by a severe form of sleep apnea attributed to greatly compromised central and peripheral chemoreflexes. In this study, we analyze whether Phox2b expression in the brainstem respiratory network is preferentially associated with neurons involve...
Task2 K(+) channel expression in the central nervous system is surprisingly restricted to a few brainstem nuclei, including the retrotrapezoid (RTN) region. All Task2-positive RTN neurons were lost in mice bearing a Phox2b mutation that causes the human congenital central hypoventilation syndrome. In plethysmography, Task2(-/-) mice showed disturbed chemosensory function with hypersensitivity t...
We observe rich phenomena of two-level random telegraph noise (RTN) from a commercial bulk 28-nm p-MOSFET (PMOS) near threshold at 14 K, where Coulomb blockade (CB) hump arises quantum dot (QD) formed in the channel. Minimum RTN is observed CB high-current level dramatically switches to low-current level. The gate-voltage dependence amplitude and power spectral density match well with transcond...
پژوهش حاضر با هدف تعیین اثربخشی آموزش تنظیم هیجان مبتنی بر مدل فرایند گراس بر کاهش خشم و تکانشگری در افراد وابسته به مواد مخدر انجام شد. پژوهش حاضر از نوع طرح های شبه آزمایشی است که از طرح پیش آزمون – پس آزمون با گروه کنترل استفاده شده است. جامعه آماری پژوهش را کلیه افراد وابسته به مواد مراجعه کننده به کلینیک های ترک اعتیاد شهرستان مریوان در سال 92-1391 تشکیل می دهند. بدین منظور تعداد 30 نفر از...
Calculemus research aims at the integration of systems for symbolic computation and symbolic reasoning and is related to the QPQ initiative. It is in the spirit of both projects to discuss these connections and potential collaborations. The following text sketches the structure and scientific contributions of the Calculemus Research Training Network (Calculemus RTN; see Figure 1 for the partner...
Hindbrain neuronal networks serving respiratory, proprioceptive, and arousal functions share a developmental requirement for the bHLH transcription factor Atoh1. Loss of Atoh1 in mice results in respiratory failure and neonatal lethality; however, the neuronal identity and mechanism by which Atoh1-dependent cells sustain newborn breathing remains unknown. We uncovered that selective loss of Ato...
از عوامل اصلی محدود کننده ماندگاری در مرحله پس از برداشت می‌توان به هورمون اتیلن اشاره نمود. لذا دست‌ورزی ژنتیکی این هورمون مورد توجه بوده و در پژوهش حاضر، لاین‌های تراریخته گل سرخ حاوی ژن جهش یافته etr1 مورد ارزیابی قرار گرفتند. در ادامه بررسی‌های تکمیلی مولکولی، فیزیولوژیک و مورفولوژیک در لاین‌ها جهت انتخاب لاین ماندگار انجام شد. علاوه بر این، پاسخ‌های فیزیولوژیک لاین‌های ماندگار و شاهد در تی...
The power consumption of digital circuits is proportional to the square operation voltage and demand for low reduces towards threshold MOSFETs. A weak signal makes vulnerable noise optimization circuit design requires modelling noise. Random Telegraph Noise (RTN) dominant modern CMOS technologies Monte Carlo has been used assess its impact on circuits. This statistical distributions RTN amplitu...
