Abstract: One or more first servers can implement an example method including storing, at a memory accessible by the first one or more servers, a primary email address for a user. The method further includes detecting a request, from a client device associated with the user, to access a network resource hosted at a second one or more servers, wherein the network resource is associated with an online service. The method also includes automatically generating a secondary email address for the user that is unique to the online service; and transmitting the secondary email address to the second one or more servers such that the online service receives the secondary email address for the user without receiving the primary email address for the user, thereby enabling the online service to transmit emails to the user despite not receiving the primary email address for the user.

Abstract: A downhole shunt tube isolation system having a fluid channel and a piston hydraulic chamber disposed within a valve actuator housing, wherein the fluid channel is sealed via a plug to hydraulically lock a valve in an open position, wherein a gravel slurry is configured to flow from a first tube segment through the valve to a second tube segment when the valve is in the open position. A portion of the plug is displaced to open a fluid path through the plug to the piston hydraulic chamber, wherein opening the fluid path to the piston hydraulic chamber hydraulically unlocks the valve, closing the valve via a biasing force to block the flow of the gravel slurry from a first tube segment through the valve to a second tube segment.

Abstract: This disclosure relates to a computer-implemented method for enabling a transaction bypass for a user-requested block on a merchant. The method involves receiving an authorization request message from a merchant, determining if the merchant is subject to an active block instruction, and verifying customer authentication information. If the authentication information is present and the merchant matches a block instruction, a transaction bypass message is generated and sent to the issuer. Based on the issuer's response, the active block may be removed or maintained. The method also allows for sending authentication data to the issuer for verification, and periodically receiving authorization requests from the merchant. Additional features include managing an authentication security threshold and sending status notifications to the merchant. The invention ensures secure transaction processing, providing flexible handling of user-requested merchant blocks based on customer authentication and issuer approval.

Abstract: Techniques are provided for verifying Access Points (APs) using crowd sourcing. In one example, a STA establishes a first non-verified connection, based on security material, with a source AP in a wireless infrastructure. A target AP in a wireless infrastructure obtains an indication that the STA is attempting to establish a second non-verified connection with the target AP. In response, the target AP establishes the second non-verified connection based on the security material.

A second chamber isolated from the wellbore environment comprises a second component with a Halbach array of magnets. The first chamber and the second chamber are coupled with a nonmagnetic separation.

Abstract: Beta-hydroxybutyrate (BHB) mineral salts and/or beta-hydroxybutyrate (?HB) free acid in combination with 1,3-butanediol (1,3-BD) were used to induce ketosis, achieving blood ketone levels of (2-7 mmol/L), with or without dietary restriction. A combination of the ketogenic compounds, ?HB acid and/or ?HB salt in together with 1,3BD was more than additive. What has been unknown until now, and what was unexpected is that the specific combination of the partially buffered ?HB free acid, (created as a mixture of ?HB free acid and ?HB salt), together with 1,3-BD in a particular combination is far more than additive. When used together this mixture raises serum levels far higher, up to 70% higher, than would be expected by using 1,3BD together with ?HB salt and/or BHB acid. The synergistic combination is 5 times more powerful at raising serum ?HB than the enantiomerically pure acid or salt alone and 1.23 times more powerful than the corresponding enantiomerically pure ester compounded from ?HB and 1,3-BD.
