본 논문은 triple-well과 twin-well에서의 고에너지 이온주입 에너지와 도즈량 변화에 따른 래치업 특성을 비교하였다. 공정시뮬레이터인 ATHENA로 소자를 제작하고 도핑프로파일 형태와 구조를 조사한 후, 래치업 특성은 소자 시뮬레이터인 ATLAS를 이용하였다. triple-well 공정이 마스크 스텝수를 줄이고, 이온주입 후 열처리시간을 단축하며 별도의 열처리 공정없이 도핑르로파일을 넓은 형태로 분포시켜 래치업 면역특성이 매우 좋은 결과를 얻었다.

We find some conditions under which G(f)-sequence of a CW-pair (X, A) is exact. And we also introduce a G(f)-sequence for a CW-triple (X, A, B) and examine when the sequence is exact.

This paper continues the study of recursion formulas of multivariable hypergeometric functions. Earlier, in [4], the authors have given the recursion formulas for three variable Lauricella functions, Srivastava's triple hypergeometric functions and k-variable Lauricella functions. Further, in [5], we have obtained recursion formulas for the general triple hypergeometric function. We present here the recursion formulas for Exton's triple hypergeometric functions.

In this work, via Orlicz functions, we have obtained a generalization of rough statistical convergence of asymptotically equivalent triple sequences a new non-matrix convergence method, which is intermediate between the ordinary convergence and the rough statistical convergence. We also have examined some inclusion relations related to this concept. We obtain the results are non negative real numbers with respect to the partial order on the set of real numbers.

In this article, we construct lacunary ∆^m-statistical convergence for triple sequences within the context of intuitionistic fuzzy n-normed spaces (IFnNS). For lacunary ∆^m-statistical convergence of triple sequence in IFnNS, we demonstrate numerous results. For this innovative notion of convergence, we further built lacunary ∆^m-statistical Cauchy sequences and offered the Cauchy convergence criterion.

The concept of lacunary statistical convergence of triple sequences with respect to gradual 2-normed linear spaces is introduced in this research. We learn about its link to some inclusion and fundamental properties. The notion of lacunary statistical Cauchy triple sequences is introduced in the conclusion, and it is demonstrated that it is equivalent to the idea of lacunary statistical convergence.

Triple-negative breast cancers constitute about 15% of all cases, but despite their higher response to neoadjuvant chemotherapy, the tumors are very aggressive and associated with a poor prognosis as well as a higher risk of early recurrence. This study was retrospectively performed on 101 patients with stage II and III invasive breast cancer who received 6-8 cycles of neo-adjuvant chemotherapy. Out of the total, 23 were in the triple negative breast cancer subgroup. Nuclear Ki-67 expression in both the large cohort group (n=101) and triple negative breast cancer subgroup (n=23) and its relation to the pathological response were evaluated. The purpose of the study was to identify the predictive value of nuclear protein Ki-67 expression among patients with invasive breast cancers, involving the triple negative breast cancer subgroup, treated with neoadjuvant chemotherapy in correlation to the rate of pathological complete response. The proliferation marker Ki-67 expression was highest in the triple negative breast cancer subgroup. No appreciable difference in the rate of Ki-67 expression in triple negative breast cancer subgroup using either a cutoff of 14% or 35%. Triple negative breast cancer subgroup showed lower rates of pathological complete response. Achievement of pathological complete response was significantly correlated with smaller tumor size and higher Ki-67 expression. The majority of triple negative breast cancer cases achieved pathological partial response. The study concluded that Ki-67 is a useful tool to predict chemosensitivity in the setting of neoadjuvant chemotherapy for invasive breast cancer but not for the triple negative breast cancer subgroup.

본 논문에서는 temperature/voltage에 둔감한 triple-mode CMOS DC-DC Converter를 제안한다. 제안된 triple-mode DC-DC converter는 단일 배터리의 수명에 따른 전압변화(3.3-5.5V)로부터 일정 또는 다양한 출력전압(0.6-2.2V)을 생성한다. 제안된 triple-mode CMOS DC-DC converter는 Pulse Width Modulator(PWM) 모드, Pulse Frequency Modulator(PPM) 모드, 그리고 Low Drop-Out(LDO) 모드, 이렇게 세 가지 모드로 동작한다. 또한, 제안된 회로는 temperature/voltage 변화에 의한 칩의 오동작을 방지하기 위해 temperature/voltage 변화에 둔감한 저 전력 1MHz CMOS ring oscillator를 사용한다. 제안된 triple-mode DC-DC converter는 단일 입력 전원소스(3.3-5.5V)에서 출력 전압(0.6-2.2V)을 생성하며, 출력 전압 ripple은 PWM mode에서 10mv, PFM mode에서 15mV, 그리고 LDO mode에서는 4mV 이하이다. 또한, 제안된 회로의 효율은 PWM mode에서 93% 이상이며, $-25-80^{\circ}C$의 온도변화에도 각 모드에서의 출력 전압 레벨의 오차는 단지 0.8% 이하로 유지한다 제안된 회로의 검증을 위해 CMOS $0.35{\mu}m$ 공정을 이용한 시뮬레이션 및 칩 테스트를 수행하였다.

When triple flames propagated in a diverging channel, the effects of fuel dilution on the lift-off characteristics of triple flames were investigated. A multi-slot burner was used to stabilize the lift-off flame especially at weak fuel concentration gradients. It was reported that there is a maximum propagation velocity at a critical concentration gradient in an open jet regardless of fuel dilution. The enhancement of a diffusion flame affected to increase the propagation velocity around critical concentration gradients. However, the influence of a confined channel on the structure of triple flames according to fuel dilution needs to be investigated compared with an open jet case. This study aimed to examine the effect of a confined channel on the structure and the propagation velocity of the triple flames according to fuel dilution. Lift-off height and propagation velocity of triple flames were investigated by employing three kinds of fuel compositions diluted by nitrogen (0%, 25%, 50% $N_2$), Fuel dilution reduced the propagation velocity of triple flame in a confined channel mainly due to the decrease of flame temperature in premixed branch. Despite the difference in fuel dilution, the propagation velocity has a maximum value at a specific fuel concentration gradient even though the critical concentration gradient increases with fuel dilution. And the critical concentration gradient in a confined channel is larger than that in an open jet due to enhancement of convective diffusion.
