Abstract: A heat flow control method, for a data center cooling system, includes determining a plurality of features corresponding to a current scene of the data center cooling system at a first time point; and determining a plurality of cooling parameters at a second time point according to the plurality of features; wherein the data center cooling system utilizes the plurality of cooling parameters to control heat flow at the second time point; wherein the second time point lags the first time point.

Abstract: A modifiable hydrogel material has main chain polymers which are modified with anchor modules in the form of predetermined functionalized single strands of DNA. The main chain polymers can be crosslinked with one another by intermolecular DNA double strand formation. A DNA sequence of the anchor modules has a predetermined number of specific sequence positions N with different base combinations and/or is blocked by a temperature-dependent DNA blocking strand. In a method for producing a hydrogel with the modifiable hydrogel material, DNA modules in the form of free DNA single strands or DNA modules in the form of predetermined DNA single strand pairs which bind to anchor modules in a complementary manner are employed for crosslinking the main chain polymers, which form an intermolecular DNA double strand at a common binding domain.

Abstract: An oriented loading system is provided. The oriented loading system includes a substrate, a plurality of wells formed in the substrate, each well having a bottom and sidewalls, a plurality of particles loaded in the wells, wherein the particle comprises a core structure and an inner layer comprising magnetic material partially covering the core structure such that a part of the core structure uncovered by the inner layer is exposed, and a metal layer comprising magnetic material deposited partially in the sidewalls of the wells, wherein the inner layer is attracted by the metal layer such that the exposed core structure is oriented towards the bottom of the well or the inner layer is oriented towards the bottom of the well.

Abstract: A process for making a low-profile choke includes steps of: providing an etchable substrate; applying a masking layer on the etchable substrate; etching the etchable substrate through perforated patterns of the masking layer to permit the etchable substrate to be formed with an array of recessed patterns, each of which includes a core recess portion and a coil-patterned recess portion; filling a magnetic material and a conductive material respectively into the core recess portion and the coil-patterned recess portion of each of the recessed patterns to form in the etchable substrate a plurality of magnetic cores and a plurality of conductive coils; and slicing the etchable substrate to obtain a plurality of choke bodies.

Abstract: A method for making a miniaturized circuit includes: depositing a bottom metal layer including a first metal on a substrate; forming a patterned photoresist layer on the bottom metal layer to expose a first portion of the bottom metal layer and to cover a second portion thereof; plating a middle circuit pattern including a second metal on the bottom metal layer to cover the first portion of the bottom metal layer; plating a top circuit pattern including a third metal different from the first metal onto the middle circuit pattern to cover the middle circuit pattern; removing the patterned photoresist layer; and etching the second portion of the bottom metal layer with an etchant, so as to pattern the bottom metal layer into a bottom circuit pattern.
