A portable terminal configured to estimate the number of used wet towels, or oshiboris, stored in a collection box, including: an information receiving unit for receives pre-collection store information; a photographing unit for capturing an image of used oshiboris stored in a collection box from above; a learning model storing unit for storing a learning model trained by a neural network; an image acquiring unit for acquiring an image for estimation photographed by the photographing unit. The estimating unit estimates a number of used oshiboris from the image for estimation acquired by the image acquiring unit, with the learning model stored in the learning model storing unit, by the neural network. The display unit displays an estimation result estimated by the estimating unit. The information transmitting unit transmits post-collection store information added the estimation result to the pre-collection store information received by the information receiving unit to the core system.

e and n are public information and d is private information. An electronic signature is generated based on a calculated value of e&#xd7;d mod n. A signature generation apparatus includes a random number generation unit, a first calculation unit, a second calculation unit, and a signature generation unit. The random number generation unit generates a random number r. The first calculation unit calculates s1=r&#xd7;n. The second calculation unit calculates s2=s1+e. The signature generation unit calculates s3=s2&#xd7;d mod n and outputs s3 as the calculated value of e&#xd7;d mod n. The signature generation apparatus can thereby generate the above electronic signature securely against differential power attacks.

Signature generation by calculating a remainder modulo public information

A scalar multiplication unit references a t-bit sequence representing a random number k one bit at a time from the most significant bit, and upon each referencing, sets in a work variable R[0] a value obtained by doubling a specific point G on an elliptic curve set in a scalar multiplication variable R, and sets in a work variable R[1] a value obtained by adding the specific point G to the work variable R[0]. The scalar multiplication unitsets the work variable R[0] in the scalar multiplication variable R if the value of the referenced bit is 0, and sets the work variable R[1] in the scalar multiplication variable R if the value of the referenced bit is 1. A scalar multiple point output unitoutputs as a scalar multiple point kG a value obtained by subtracting a constant value 2tG from the scalar multiplication variable R.

A method for culturing hepatocytes, wherein hepatocytes embedded in an extracellular matrix is placed on a gas-permeable membrane and the hepatocytes are cultured while being supplied with oxygen from the gas-permeable membrane side. By this, the polarity in the hepatocytes can be induced and a bile canaliculus can be formed in a short period of time. Further, the formed polarity can be maintained for a longer period.

The invention is directed to methods for the propagation or cultivation of cells including preparing a cell culture substrate, wherein the cell culture substrate includes a substrate and a layer formed by surface modification. The layer includes a polymer containing an amino group. The polymer is produced by reacting a polymer represented by formula (II): with a polymer having at least one amino group, &#x2014;NH, capable of forming a Schiff base in a monomer of formula (II), thereby forming a polymer layer constituting the layer formed by surface modification. 'n' in Formula (II) is 0 or a positive integer, and m is a positive integer. n and m represent the degree of polymerization. Formula (II) is formed by chemical vapor deposition of formyl[2.2]paracyclophane. The methods further include providing cells in a medium; inoculating the cells onto the cell culture substrate; and culturing the cells, wherein the cells adhere to the cell culture substrate.

Cell culture substrate and its production method

The present invention provides a method for detection or determination of vitamin C by luminescence that employs a redox-responsive fluorogenic probe consisting of porphyrin or phthalocyanine with a nitroxide radical(s), or that employs a liposome preparation comprising the said redox-responsive fluorogenic probe. The present method can overcome the problems of prior art methods, and in particular, are applicable for bioimaging to allow elucidation of the behavior of vitamin C in vivo.
