He had hypotension with severe metabolic acidosis (lactate 20 mmol/L, pH 7.0, bicarbonate [HCO₃] 11 mmol/L) and an anion gap of 35 mEq/L. He was admitted …

Hybrid Multicast Transport Support, Anonymous

Defensive Publications Series

RFC 6513 and RFC 6514 define NG-MVPN procedures in which PEs use BGP MCAST-VPN routes (e.g., RT-1 I-PMSI A-D) to auto-discover participation and to bind multicast delivery to a provider tunnel (P-tunnel) identified by the PMSI Tunnel attribute (Tunnel Type plus identifiers/labels). In practice, a single PMSI binding typically forces a single transport choice across all leaves (e.g., mLDP P2MP for core-efficient replication or ingress replication for simplified edge requirements), limiting mixed-capability deployments. This document describes techniques that allow heterogeneous P-tunnel transports within one NG-MVPN instance by having an ingress PE concurrently support multiple tunnel types and admit egress PEs …

Tone Mapping Using Negative Values To Represent Luminance Below Reference Black, Yannis Guyon, Nathan Gauër

Defensive Publications Series

High Dynamic Range (HDR) tone mapping traditionally extends brightness above a reference white value but uses a fixed floor of zero for black, which maps to a display's minimum luminance setting. This limits creative control over shadow detail by content creators, e.g., the ability to choose blacks deeper than those for which legacy content was mastered or to choose to keep content at a reference black regardless of a display's minimum luminance setting. This disclosure describes a method for extending the HDR tone-mapping range to include negative values, allowing for greater flexibility in tone mapping shadows. In this approach, the …

Optimal Synce Source Selection In Networks Employing Macsec Security, Anonymous

Defensive Publications Series

A timing-distribution technique is described for telecom packet networks that use IEEE 1588 PTP (e.g., ITU-T G.8275.1 full timing support) for phase/time and SyncE for frequency, where SyncE master selection is primarily based on Quality Level (QL) conveyed via ESMC. In networks that simultaneously deploy hop-by-hop MACsec and end-to-end (tunneled) MACsec domains, operational visibility of the true SyncE “trail” can become ambiguous, leading downstream nodes to select a locally acceptable but performance-inferior frequency reference that traverses additional unsecured/opaque intermediate hops and accumulates more jitter/wander. To bias selection toward more deterministic, regenerated hop-by-hop SyncE paths, the disclosure proposes encoding a MACsec-topology …

Far-End Media Effect Configurations To Avoid Unconscious Hallucinations And Other Far-End Processing Issues, Jieyu Tan, Soya Li, Espen Berger, Wallice Wang

Defensive Publications Series

In video conferencing scenarios, when a user makes a media (video) call, a video/sharing/audio preview viewed on the sender's side may not be what is actually presented on the receiver's side. For example, some post-processing modules (e.g., super-resolution, flicker detection, voice correction, etc.) that operate on the receiver's side can bias the sender's media effects. Techniques are proposed herein that provide for embedding post-processing configuration metadata into a media stream package by a media sender's device. Using the proposed techniques, a media sender can pre-rehearse a meeting and/or perform an in-meeting preview and customize their media stream to avoid hallucinations …

Fasttree-Guided Genetic Algorithm For Credit Scoring Feature Selection, Rashed Bahlool, Nabil Hewahi Prof., Youssef Harrath Dr.

Research & Publications

Feature selection is pivotal in enhancing the efficiency of credit scoring predictions, where misclassifications are critical because they can result in financial losses for lenders and exclusion of eligible borrowers. While traditional feature selection methods can improve accuracy and class separation, they often struggle to maintain consistent performance aligned with institutional preferences across datasets of varying size and imbalance. This study introduces a FastTree-Guided Genetic Algorithm (FT-GA) that combines gradient-boosted learning with evolutionary optimization to prioritize class separability and minimize falserisk exposure. In contrast to traditional approaches, FT-GA provides fine-grained search guidance by acknowledging that false positives and false negatives …
