The enumeration of cells in fluids by flow cytometry is widely used across many disciplines such as assessment of leukocyte subsets in different bodily fluids or of bacterial contamination in environmental samples, food products and bodily fluids. For many applications the cost, size and complexity of the instruments prevents wider use, for example, CD4 analysis in HIV monitoring in resource-poor countries. The novel device, methods and algorithms disclosed herein largely overcome these limitations. Briefly, all cells in a biological sample are fluorescently labeled, but only the target cells are also magnetically labeled. The labeled sample, in a chamber or cuvet, is placed between two wedge-shaped magnets to selectively move the magnetically labeled cells to the observation surface of the cuvet. An LED illuminates the cells and a CCD camera captures the images of the fluorescent light emitted by the target cells. Image analysis performed with a novel algorithm provides a count of the cells on the surface that can be related to the target cell concentration of the original sample. The compact cytometer system provides a rugged, affordable and easy-to-use technique, which can be used in remote locations.

For many applications the cost, size and complexity of the instruments prevents wider use, for example, CD4 analysis in HIV monitoring in resource-poor countries. The novel device, methods and system disclosed herein largely overcome these limitations. The system includes a simple system for CD4 and CD8 counting in point-of-care HIV staging within resource poor countries. Unlike previous approaches, no sample preparation is required with the sample added directly to a chip containing dried reagents by capillary flow. A large area image cytometer consisting of an LED module is used to excite the fluorochromes PerCP and APC labeled targets and a monochrome CCD camera with a combination of two macro lenses captures images of 40 mm² of blood (approximately 1 microliter). CD4 and CD8-T-lymphocyte counts correlate well with those obtained by flow cytometry. The cytometer system described in the present invention provides an affordable and easy-to-use technique for use in remote locations.

A method and system are provided for a part-of-speech tagger that may be particularly useful for resource-poor languages. Use of manually constructed tag dictionaries from dictionaries via bitext can be used as type constraints to overcome the scarcity of annotated data in some instances. Additional token constraints can be projected from a resource-rich source language via word-aligned bitext. Several example models are provided to demonstrate this such as a partially observed conditional random field model, where coupled token and type constraints may provide a partial signal for training. The disclosed method achieves a significant relative error reduction over the prior state of the art.

The invention discloses a process for calcining and preparing sulphuric acid by a fluidized bed furnace for desulfurizing waste residue of power plants. The process takes desulfurized waste residue of the power plants, sulfur and discarded coke dust as raw materials and employs the fluidized bed calcining furnace to initially prepare sulfur dioxide, wherein the obtained sulfur dioxide has the concentration of 8-13%, and then the obtained sulfur dioxide is taken as the raw material to prepare the sulphuric acid by employing the prior art, wherein the obtained sulphuric acid has the concentration of 93-98%. The process not only resolves the problem of after-treatment of the wastes and enables the wastes to be recycled, but also saves pyrite resources poor at home, and the generated economical benefits are quite considerable. And a calcium oxide waste residue is also generated in the process of production, which can be taken as desulfurizer of the power plants to be recycled after cooling treatment. Therefore, the process employed by the invention to prepare the sulphuric acid not only reduces cost for producing the sulphuric acid, but also reduces cost of thermal power plants.

The invention relates to an LTE technology-based resource allocation method for the uplink of an internet of things. The invention provides a solution for realizing the internet of things based on the LTE technology and also provides an allocation method for uplink resources based on QoS. In the resource-poor condition, resources are allocated to delay-sensitive users preferentially, so that the bandwidth requirements of the above users are met. In the resource-rich condition, resources are allocated to users as required according to the actual requirements of the users. On the basis that the QoS is met, the resource utilization rate of the system is maximized.

Boosted cytidine analogue reverse transcriptase inhibitor antiretroviral compound is a new therapeutic anti HIV option, in combination with another drug such as a NRTI or a protease inhibitor. It's heightened and sustained antiretroviral potency is due to the increased intracellular level of 3TC triphosphate, the active form of 3TC. This effect is obtained by combining 3TC, in usual doses, with a reduced dose of ddC, in the same pharmaceutical formulation. The product could be administered twice or even once daily, which is convenient, and does not increase the pill burden for the patient. The reduced ddC dosage prevents the occurrence of ddC related side effects. Other cytidine derivatives (racemic or negative enantiomers) could have the same effects as ddC and could probably be combined with 3TC, and have the same effect. On the other hand, low dose ddC may also increase the intracellular levels of other cytidine derivatives as it does for 3TC. Boosted cytidine analogue reverse transcriptase inhibitor antiretroviral compound could also be formulated in combination with another drug such as another NRTI (e.g. abacavir) or any protease inhibitor in the same capsule or tablet. This approach offers a dual anti-HIV therapy that is as efficacious as the routine triple therapy. In this way the HIV treatment cost could be significantly reduced which is imperative for resource-poor settings. This new formulation is convenient and well tolerated with no additional toxicity than that of the combining drug (NRTI or protease inhibitor) and 3TC. Moreover, this will enable a larger number of patients to benefit from the already known 3TC effects. It will also increase the 3TC effects in those organs or HIV sanctuaries with usually reduced 3TC concentrations or activity. It could be indicated in both the initial as well as in salvage HIV therapy. It could also be used for therapy optimization or simplification. Moreover, in combination with another NRTI such as abacavir, or even alone, it could be beneficial for reducing the HIV harm in resource-poor settings.

When a mobile device is connected to another mobile device without subscribing to a specific service or a private network, SA may be established. For example, the SA may be used for resource saving and secure connections of resource poor devices (for example, a medical patch) having a relatively poor resource, such as insufficient battery power or computing power.

A demultiplexer demultiplexes a supplied code string, to obtain the quantized low-band spectrum, the spectral characteristic code, and the quantized expansion coefficient(s). At this point, the code string includes a single quantized expansion coefficient or quantized expansion coefficients of the respective bands in the high band depending on the spectral characteristic code. A spectral inverse quantization unit obtains the low-band spectrum by inversely quantizing the quantized low-band spectrum. An expansion coefficient inverse quantization unit obtains the expansion coefficient(s) by inversely quantizing the quantized expansion coefficient(s). An expanded spectrum generation unit generates an expanded spectrum, in accordance with the low-band spectrum and the expansion coefficient(s) depending on the spectral characteristic code. An IMDCT unit generates a band-expanded time-series signal from the low-band spectrum and the expanded spectrum. The present technology can be applied to decoding devices.
