The unique rapid variabilities of the iron K line profiles in NGC 4151
We present a detailed analysis of the iron K line variabilities in
NGC 4151 by using long ASCA observation data obtained in May 1995. Despite the
relatively small amplitude variations in the continuum flux, the iron K
line flux and profile show dramatic variations. Particularly, the line profile
changes from single peak to seeming double peaks and back in time scales of a
few 10 sec. The seemingly double-peaked profiles can be well interpreted as
line emission from a Keplerian ring around a massive black hole. An absorption
line at around 5.9 keV is also marginnaly detected. We discussed current Fe K
line models, but none of them can well explain the observed line and continuum
variations.Comment: 18 pages, latex, 3 figures, ApJ accepte

EVOLUTIONARY MATHEMATICS AND SCIENCE FOR TWO ASPECTS OF BINOMIAL COEFFICIENTS: POLYNOMIAL AND COMBINATION
Tsao, Hung-ping (2021). Evolutionary Mathematics and Science for Two Aspects of Binomial Coefficients: Polynomial and Combination. In: "Evolutionary Progress in Science, Technology, Engineering, Arts, and Mathematics (STEAM)", Wang, Lawrence K. and Tsao, Hung-ping (editors). Volume 3, Number 8, August 2021; 42 pages. Lenox Institute Press, Auburndale, MA, 02466, USA. No. STEAM-VOL3-NUM8-AUG2021; ISBN 978-0-9890870-3-2. ............ABSTRACT: We make distinction of two important roles for binomial coefficients to play in Number Theory and Trigonometry, respectively. The polynomial aspect of C (n, k) enables the derivation of both explicit and implicit formulas for sums of powers of arithmetic progressions, whereas its combinatorial aspect helps the derivation of multiple angle formulas for Sine, Cosine and Tangent functions. ..........KEYWORDS: Polynomial expression, Sorting, Commutative ring, Stirling number, Eulerian number, Natural sequence, Powered sum, Binomial coefficient, Pascal triangle, Bernoulli coefficient, Arithmetically progressive sequence, Recursion, Iteration, Trigonometry, Multi angle formula Sine, Cosine, Tangent, De Moivre’s Theorem
Unusual signatures of the ferromagnetic transition in the heavy Fermion compound UMnAl
Magnetic susceptibility results for single crystals of the new cubic
compounds UTAl (T=Mn, V, and Mo) are reported. Magnetization,
specific heat, resistivity, and neutron diffraction results for a single
crystal and neutron diffraction and inelastic spectra for a powder sample are
reported for UMnAl. For T = V and Mo, temperature independent Pauli
paramagnetism is observed. For UMnAl, a ferromagnetic transition is
observed in the magnetic susceptibility at = 20 K. The specific heat
anomaly at is very weak while no anomaly in the resistivity is seen at
. We discuss two possible origins for this behavior of UMnAl:
moderately small moment itinerant ferromagnetism, or induced local moment
ferromagnetism.Comment: 5 pages, 5 figures, to be published in Phys. rev.
REMEMBERING MY PARENTS, WIFE AND GENERAL DAI LI 回 憶 父 母 , 愛 妻 及 戴 笠 將 軍
Wang, Puchen 王 蒲 臣 (2022). Remembering My Parents, Wife and General Dai Li, In: “Global Humanities and Liberal Arts (GHLA)”, Wang, Lawrence K. 王 抗 曝 (editor).

ABSTRACT: Major General WANG Puchen (王 蒲 臣 將 軍), the author, was born in China's Zhejiang province (浙 江 省) and once humorously honored as the world's oldest spy (104 years old). General Wang was the Director of the Bureau of Investigation and Statistics for northern China stationed in Beijing (軍 統 / 保 密 局 北 平 站 督 察 長) and reported directly to China's National Intelligence Director DAI Li (戴 笠) when mainland China was being gradually taken over by the Communist after World War II. General Wang appeared in some modern Chinese movies, such as All Quiet in Peking (北 平 無 戰 事) due to his important historical role. After General Wang's testing water in China's Yung-Nan Province (雲 南 省), President CHIANG Kai-Shek (蔣 介 石) decided to totally retreat to Taiwan (臺 灣) instead of Yung-Nan and other southern provinces. So the direction of modern Chinese history was altered by General Wang. This publication is one of many General Wang's old memoirs consisting of his seven short articles: (a) Thinking of Relatives on Father's Day 每 逢 佳 節 倍 思 親, 寫 於 民 國 七 十 五 年 父 親 節 ; (b) Dear Dad, I Am Sorry 爸 爸 , 我 對 不 起 您 ; (c) Remembering My Dear Mother 懷 念 母 親 ; (d) Parents and Children 父 母 , 子 女 ; (e) In Memory of My Dear Wife, CHU Shou-Yu on Her Passing Anniversary 先 室 朱 秀 毓 女 士 週 年 祭 ; (f) Forever Living in My Hearts 永 遠 活 在 我 的 心 中 ; (g) An Old Cloth Having Thousands Threads of Loving Friendship: Remembering Late General DAI Yu-Nong (i.e. General DAI Li ) on His 90th Birthday 一 襲 舊 衣 萬 縷 情 - - 戴 雨 農 先 生 九 秩 冥 誕 述 懷

Lenox Institute Press, Newtonville, NY, 12128-0405, USA. No. STEAM-VOL2-NUM1-JAN2020; ISBN 978-0-9890870-3-2---------------The authors present the overall structural design, design criteria, and performance data of the two Krofta Sandfloat flotation-filtration clarifiers (DAFF; SAF-BP24) installed at the 2.0 MGD (7570 m3/day) Lee Plant in treatment of surface water for potable purposes. Lenox Institute of Water Technology (LIWT) invented and patented the innovative DAFF system, while Krofta Engineering Corporation (KEC) manufactured and installed the Lee Plant. The author also discuss (a) current corrosion control program in order to comply with the US Federal Copper and Lead Rule, and (b) the current DAF-filtration plant’s performance for removal of perchlorate, barium, sodium, disinfection by-products (DBP), total trihalomethane (THM), total haloacetic acid (HAA), microbial contaminants, turbidity, iron and manganese. The 19 years old innovative Lee DAF-filtration plant met all US Environmental Protection Agency, and the Commonwealth of Massachusetts primary and secondary drinking water standards in accordance with the 2018 Water Quality Report. The Town of Lee successfully uses zinc orthophosphate and pH adjustment to stabilize the water throughout of Lee distribution system for lead, copper and pipe corrosion control.

Quantum critical behavior in the heavy Fermion single crystal Ce(NiPd)Ge
We have performed magnetic susceptibility, specific heat, resistivity, and
inelastic neutron scattering measurements on a single crystal of the heavy
Fermion compound Ce(NiPd)Ge, which is believed to
be close to a quantum critical point (QCP) at T = 0. At lowest
temperature(1.8-3.5 K), the magnetic susceptibility behaves as with m/mole
(0.0025 emu/mole). For 1 K, the specific heat can be fit to the formula
with of order 700 mJ/mole-K.
The resistivity behaves as for temperatures below 2
K. This low temperature behavior for and is in accord
with the SCR theory of Moriya and Takimoto\cite{Moriya}. The inelastic neutron
scattering spectra show a broad peak near 1.5 meV that appears to be
independent of ; we interpret this as Kondo scattering with 17 K. In
addition, the scattering is enhanced near =(1/2, 1/2, 0) with maximum
scattering at = 0.45 meV; we interpret this as scattering from
antiferromagnetic fluctuations near the antiferromagnetic QCP.Comment: to be published in J. Phys: Conference Serie
