Given an arrayxof sizen > 3and an integerN, return the indices of three elements in the array that sum up to the given integerN. If there is no such triplet, return -1. For example, givenx = [1 4 2 5 8 10]andN = 17, the function should return[2 4 5]becausex(2) + x(...
Photolysis has enabled the occurrence of numerous discoveries in chemistry, drug discovery and biology. However, there is a dearth of efficient long wavelength light mediated photolysis. Here, we report general and efficient long wavelength single photon method for a wide array of photolytic molecules...
其中三个数位置关系满足:array[i] < array[j] < array[k], i < j < k 也就是说,三个数以及数组中的位置只要依次递增即可。 思路一: 遍历数组中的所有元素,三个数组和的所有情况,枚举所有可能进行判断 简单粗暴,时间复杂度较高O(N ^ 3),空间复杂度O(1) 1publicclassSolution {2publicbooleanincreasing...
\(\mathcal {L}\) in Eq. 28 represents the final loss of the model. $$\begin{aligned} \mathcal {L}_{a\rightarrow o}= & -\sum _{i} y_i^alog(v_i^a)-\sum _{i} \sum _{j} y_{i,j}^{a\rightarrow o}log(u_{a\rightarrow o}) \end{aligned}$$ (26) $$\begin{...
A triplet is an array of three integers. You are given a 2D integer array triplets, where triplets[i] = [ai, bi, ci] describes the ith triplet. You are also given an integer array target = [x, y, z] that describes the triplet you want to obtain. ...
Question: Given an unsorted array return whether an increasing subsequence of length 3 exists or not in the array. Formally the function should: Return true if there existsi, j, k such thatarr[i]<arr[j]<arr[k]given 0 ≤i<j<k≤n-1 else return false. ...
57,74 On the contrary, when the TMPTA was added, a sum of two exponential functions that incorporate two time-components (τDF and τDS) was necessary to adequately model the resultant intensity decay dynamics. The τDS corresponds to the lifetime of the S2 state of ZnTPP in pure CH3CN ...

(3.1), while the sum of the cross sections ij σij drops from 18 to 4 as seen in eq. (3.2), so that the effective annihilation cross section at the late time becomes twice larger than the one before the decoupling. Next, the effective annihilation cross section with the Sommerfeld ...
The derivation of the solution of the density matrixρ14 From Eq. (12), when the time is explicitly shown in the equations of ∂tρ12, ∂tρ13, and ∂tρ14, it follows that $$\begin{array}{rcl}{\partial }_{t}{\rho }_{12}(t) & = & i({{\rm{\Delta }}}_{2}+i{...
