Abstract: Disclosed is a bile acid-metronidazole conjugate or a stereoisomer thereof, or a salt thereof, or a solvate thereof, or a prodrug thereof, or a metabolite thereof. The bile acid-metronidazole conjugate is prepared using an esterification reaction of a bile acid compound with hydroxyl group on a metronidazole structure. The synthesis process is simple and easy for industrialization. The bile acid-metronidazole conjugate can effectively inhibit the growth of anaerobic bacteria, especially the growth of Clostridioides difficile and Helicobacter pylori, so that the bile acid-metronidazole conjugate has a significantly improved therapeutic effect in the treatment of infections caused by the anaerobic bacteria.

Abstract: The disclosure provides a method for universal naming convention (UNC) path redirection between a local desktop and a remote desktop. The method generally includes selecting, by a client device in an internal network, via an application running on a remote desktop in an external network, to open a UNC path for a resource located in the internal network. A firewall restricts the external network to access the resource located in the internal network. The method generally includes receiving, at the client device, from the remote desktop, via a virtual channel between the external network and the client device in the internal network, a message indicating to open the UNC path. The method generally includes opening, by the client device, via a local application of the client device, the UNC path to access the resource located in the internal network.

A plurality of support bars arranged in an array between the first support plate and the second support plate. A first planar display portion is fixedly connected to the first support plate, a second planar display portion is fixedly connected to the second support plate, and a curled display portion is in contact with at least part of the plurality of support bars but is not connected to the at least part of the plurality of support bars.

Abstract: Example methods and systems to implement an economic printing mode are described. In one example, a computer system may provide a user interface specifying multiple selectable levels associated with economic printing mode. The source printing content may be transformed to generate target printing content that is printable using a lower ink consumption compared to the source printing content. For example, in response to a selection of a first level, print quality may be reduced. In response to a selection of a second level, image information in the source printing content may be modified. In response to a selection of a third level, font information associated with textual information in the source printing content may be modified. The computer system may provide the target printing content that includes modified font information to the printer for printing and/or generate a preview of the target printing content prior to printing using the printer.

Abstract: Secure printing may be performed in a virtual desktop infrastructure (VDI) in a virtualized computing environment. When a file is selected for secure printing, print data for the file is stored, and a corresponding entry is created in a metadata map. A message is sent to a user device to inform a user that the file is available for secure printing. The message may include a uniform resource locator (URL) link having a hash code corresponding to the stored print data. If the user accesses the URL link to request the secure printing, the hash code is retrieved from the URL link and compared against the entry in the metadata map. If there is a match between the hash code and the entry in the metadata map, the file is sent to a target local printer for printing.

Abstract: The disclosure provides a method of associating thread identifiers (IDs) to input/output (I/O) requests in a remote computing environment. The method generally includes receiving, by a mini-filter on a remote device that is remote from a client device, a request from an application on the remote device to access resources at the client device, determining, by the mini-filter, a thread identifier (ID) associated with the request, the thread ID corresponding to an application thread of the application that generated the request, determining, by the mini-filter, one or more parameters of the request, and transmitting, by the mini-filter, to a redirection server process on the remote device, a message comprising the thread ID and the one or more parameters of the request, wherein the thread ID and the one or more parameters of the request are added to a cache maintained by the redirection server process.

Abstract: System and methods are provided for improved directory enumeration on shared client directories in virtual desktops. A merged I/O request containing multiple expected I/O requests for enumerating a directory can be produced on the virtual desktop. The merged I/O request can be conveyed to the client device and a merged I/O response containing multiple I/O responses to the expected I/O requests can be received from the client device. The received I/O responses can be stored in cache memory on the virtual desktop and used to respond to subsequent queries for enumerating the directory on the virtual desktop.

Abstract: System and method are described for copying and pasting files and folders between a client and a virtual desktop via clipboard redirection. A virtual desktop session can be established by the client on the virtual desktop. The user can copy a file or folder to the virtual desktop clipboard and a path corresponding to the file or folder can be stored in the virtual desktop clipboard in a path list. When the user ungrabs the agent or switches focus out of the virtual desktop to the client, the path list can be transferred to the client device and set into the client clipboard. Subsequently, a request can be received in the client device to paste the copied file or folder to a target location in the client device. In response to the request, the client device can retrieve the contents of the copied file or folder from the agent and the contents can be placed in the target location to complete the paste operation.

Abstract: Example methods and systems are described to add a watermark for printing in a virtual desktop environment having an agent side and a client side. A watermark can be configured at the agent side for printing at the client side. At the agent side, a fallback font can be determined for text of the watermark, and coordinate space calculation can be performed, so that the watermark prints correctly at the client side.

Abstract: The capability to print to a portable document format (PDF) file is provided in a virtualized computing environment that supports a virtual desktop infrastructure (VDI). Printing-related properties, of local printers coupled to a client device, are provided to a host, so that virtual printers at the host can be configured with the printing-related properties. A simulator may be provided at the host to receive the printing-related properties from the client device and to receive a query from a virtualized computing instance for the printing-related properties, instead of the query being directly sent to the client device.

Abstract: A method of copying at least first and second files stored in a client computing device to a host server, includes the steps of: generating at the host server a first read I/O request for data of the first file based on responses to pre-read I/O requests for the first file, received from the client computing device; transmitting a merged I/O request that includes the first read I/O request for data of the first file and pre-read I/O requests for the second file from the host server to the client computing device; generating at the host server a second read I/O request for data of the second file based on responses to the pre-read I/O requests for the second file, received from the client computing device; and transmitting the second read I/O request for data of the second file from the host server to the client computing device.

Abstract: A print driver store is usable for redirection printing in a virtualized computing environment that supports virtual desktops. Native print drivers are uploaded to the print driver store from a client side. When an agent attempts to instantiate a virtual printer at the agent side that corresponds to a physical printer at the client side, the agent checks to determine if a native print driver for the physical printer is installed at the agent side. If the native print driver is not installed, then the agent obtains the native print driver from the print driver store and installs the native print driver at the agent side. The agent completes the instantiation of the virtual printer at the agent side and associates the native print driver with the virtual printer.

Abstract: A method of performing open and close input/output (I/O) requests targeting a directory of a client computing device includes the steps of: receiving a first I/O request to open the directory, from a driver of a host server, forwarding the first I/O request to the client computing device; in response to the first I/O request, receiving an identifier (ID) of the directory from the client computing device and transmitting the ID to the driver; in response to receiving a second I/O request to close the directory, from the driver, storing the ID in a cache, and not forwarding the second I/O request to the client computing device; and in response to receiving a third I/O request to open the directory, from the driver, retrieving the ID from the cache, and transmitting the ID to the driver again.
