Abstract: An external cavity laser and a tuning method therefor are provided. The external cavity laser includes a gain chip, and a tunable reflector. The tunable reflector includes a main waveguide, a beam splitter, a first branch waveguide, a first photonic crystal modulator, a second branch waveguide, and a second photonic crystal modulator. The beam splitter is configured to equally split the optical signal transmitted by the main waveguide into a first optical signal and a second optical signal and is configured to transmit the first optical signal to a first branch waveguide and the second optical signal to a second branch waveguide. A first photonic crystal modulator is configured to tune the first optical signal transmitted by the first branch waveguide. A second photonic crystal modulator is configured to tune the second optical signal transmitted by the second branch waveguide.

Abstract: The present disclosure relates to the field of medicine and specifically to an application of naringin combined with rapamycin in preparation of medications for treating hyperlipidemia. Naringin achieves anti-inflammatory and lipid-lowering effects by inhibiting the formation of oxLp-NLRP3 complexes. The present disclosure has been substantiated through cellular experiments and animal experiments, it demonstrates that naringin effectively intervenes in the early progression of hyperlipidemia by neutralizing oxLp and inhibiting the formation of oxLp-NLRP3 complexes. The inhibitory effect of naringin on oxLp-NLRP3 complexes contributes to unleashing the therapeutic potential of rapamycin in hyperlipidemia, providing a combined strategy for the prevention and treatment of hyperlipidemia-related diseases in clinical applications.

Abstract: A compound represented by general formula (I) or a stereoisomer, tautomer, deuterated substance, solvate, prodrug, metabolite, pharmaceutically acceptable salt or co-crystal thereof, an intermediate thereof and a preparation method therefor, as well as an application in preparation of a drug for treating diabetes.

Abstract: A technique manages objects in a software development project. In particular, in response to receiving a commit request for committing a group of objects, a group of historical commit requests associated with the group of objects are acquired based on a commit history, wherein historical commit requests in the group of historical commit requests involve the group of objects. A candidate object is selected from at least one object involved in the historical commit requests that is different from the group of objects. An association relationship between the candidate object and the group of objects is determined. The candidate object is identified as a missing object in response to determining that the association relationship satisfies a predetermined condition, the missing object indicating an object associated with the commit request but not included in the commit request. Accordingly, objects that are missing in a commit request can be automatically checked.

Abstract: A linkage device for implementing no backrest clearance, a supporting frame, a seat unit, and a seat, including a bottom base, a linkage mechanism, a support side plate, and a backrest mechanism; the support side plate is provided with a side plate linkage point and a backrest point; the support side plate is rotatably connected to the linkage mechanism at the side plate linkage point; the support side plate is rotatably connected to the backrest mechanism at the backrest point; the backrest mechanism includes a backrest mounting member and a backrest linkage member; and when the backrest mechanism is retracted to an ultimate position, an included angle ? between a connecting line between two ends of the backrest mounting member and a connecting line between the backrest point and the side plate linkage point is an acute angle.

Abstract: A method and apparatus for forming tungsten features in semiconductor devices is provided. The method includes exposing a top opening of a feature formed in a substrate to a physical vapor deposition (PVD) process to deposit a tungsten liner layer within the feature. The PVD process is performed in a first processing region of a first processing chamber and the tungsten liner layer forms an overhang portion, which partially obstructs the top opening of the feature. The substrate is transferred from the first processing region of the first processing chamber to a second processing region of a second processing chamber without breaking vacuum. The overhang portion is exposed to nitrogen-containing radicals in the second processing region to inhibit subsequent growth of tungsten along the overhang portion. The feature is exposed to a tungsten-containing precursor gas to form a tungsten fill layer over the tungsten liner layer within the feature.

Abstract: An apparatus for modifying a middleware shared by multiple tenants by preparing a data packet comprising modification information and tenant information, the modification information comprising information of a specific class to be modified in the middleware as well as modification content for the specific class, the tenant information indicating a specific tenant of the plurality of tenants to which the modification content is directed; and in response to acquisition of the data packet: modifying the specific class in the middleware in runtime according to the modification information to create a modified specific class; and applying the modified content only to the specific tenant. When multiple tenants share a same middleware, different versions of the middleware may be provided for respective tenants, without affecting the use by other tenants, thereby satisfying sharing and customization requirements of each of the multiple tenants.

Abstract: An apparatus for the gasification of coal or other carbonaceous material is provided for operation at an elevated pressure of at least 30 psia, preferably, between 30 psia and 150 psia. Coal or other carbonaceous material passes downwards through two interconnected sections of a gasifier. In the upper section the coal is dried and partially devolatalized and so converted into a char before it passes into the lower section where it is converted, by reaction with steam and air, into ash and a gaseous mixture of carbon monoxide, hydrogen, carbon dioxide, methane, ethane, ethylene, hydrogen sulphide, carbonyl sulphide and small amounts of ammonia and phenols. The coal, ultimately converted to ash, exits the gasifier through a flanged semi-spherical containment section that has an integrated rotating grate, which collects and disposes of the ash and through which pass the air and steam used as reactants in the gasifier.
