但无须回避，试行这一制度，也存在不同学校不同学科对博士生的考核要求不同的问题。如相对于理工科博士大多要参与导师的课题、项目，要给导师干活，导师对申请者的考核比较严格不同，文科生申请博士，由于导师承担资助经费相对较少，且有的文科导师并不需要学生给自己的项目干活，也就更容易出现“放水”问题。另外，舆论质疑的“人情交易”“钱学交易”“权学交易”“近亲繁殖”等问题，也在个别学校的个别导师招收博士生时存在，被举报、曝光。
Tecno just unveiled a rather intriguing modular smartphone concept design at MWC 2026. The standout feature here is likely the size. Most modular smartphone concepts start bulky and only get bulkier once attaching accessories.

Another way to look at our threshold matrix is as a kind of probability matrix. Instead of offsetting the input pixel by the value given in the threshold matrix, we can instead use the value to sample from the cumulative probability of possible candidate colours, where each colour is assigned a probability or weight . Each colour’s weight represents it’s proportional contribution to the input colour. Colours with greater weight are then more likely to be picked for a given pixel and vice-versa, such that the local average for a given region should converge to that of the original input value. We can call this the N-candidate approach to palette dithering.
