摘要:
A method for analyzing a genome of a single cell is provided, and a kit is also provided. The method for analyzing the genome of the single cell may comprise separating and lysing the single cell to obtain a whole-genome DNA of the cell; subjecting the whole-genome DNA to a whole-genome amplification to obtain a whole-genome amplification product; performing a PCR amplification using the whole-genome amplification product as template and using housekeeping-gene-specific primers to detect the housekeeping gene of the whole-genome amplification product; and determining whether the whole genome amplification product meets a requirement for sequencing based on the detection result, wherein a uniform distribution of the amplification product in each chromosome is an indication of the amplification product meeting the requirement for sequencing.

A wearable device having a display and a touchscreen is disclosed. The device is capable of interfacing with and controlling remotely controllable devices. The device is capable of sensing swipes, touches, and gestures, which are mapped to custom command and control functions. Swipes and touches may be with one finger or multiple fingers simultaneously, Gestures may be any motion limited only by the sensitivity of the motion sensing devices. In alternative embodiments, the device further consists of a speaker and microphone to allow spoken commands to be used in conjunction with, or replace, swipe, touch, and gestures to enhance the efficiency or ease of use of the device. In other alternative embodiments, the device may connect to a remote controllable device through a cloud, internet, or cellular network.

摘要:
A filter medium for an air filter unit for collecting dust from an airflow includes a pre-collection layer, a principal collection layer and an air-permeable cover layer. The pre-collection layer collects a part of the dust in the air flow. The principal collection layer includes a porous polytetrafluoroethylene film. The principal collection layer is positioned on a downstream side of the air flow relative to the pre-collection layer to collect dust that passes through the pre-collection layer. The air-permeable cover layer is positioned as an outermost surface layer of the filter medium on an upstream side of the air flow to allow dust in the air flow to pass through. The air-permeable cover layer is configured to suppress deformation of a surface of the filter medium caused by pressing force from an outside. Preferably, an air filter unit includes the filter medium in a zigzag shape.
