Biomedical Knowledge Graphs (BKGs) integrate diverse datasets to elucidate complex relationships within the biomedical field. Effective link prediction on these graphs can uncover valuable connections, such as potential novel drug-disease relations. We introduce a multimodal approach that unifies embeddings from specialized Language Models (LMs) with Graph Contrastive Learning (GCL) enhance intra-entity while employing Embedding (KGE) model capture inter-entity for effective prediction. To...
Low-rank adaptation (LoRA) has emerged as a powerful method for fine-tuning large-scale foundation models. Despite its popularity, the theoretical understanding of LoRA remained limited. This paper presents analysis by examining connection to Mixture Experts Under this framework, we show that simple reparameterizations matrices can notably accelerate low-rank matrix estimation process. In particular, prove reparameterization reduce data needed achieve desired error from an exponential...
This paper proposes a high rate spatial modulation transmission scheme based on the concept of Spatial Constellation (SC) and SC codewords introduced in [1]. In proposed scheme, transmitted signal vectors are generated by multiplying with constellation symbols drawn from conventional QAM or PSK constellation. The entries will determine how weighted which transmit antennas among total nT activated to signals. Different allow us have different ways symbols. Thus, information bits born not only...
Prototyping distributed applications for VANETs requires an accurate large-scale simulation scenario where many nodes interact with one another in a complex way. To test and troubleshoot the application, node states their evolution must be inspected. This process can made easier by interactive graphical user interface showing state at different levels of detail. In this paper, we propose ELVS, general purpose visualization framework encapsulating VANET simulator based upon JiST/SWANS SUMO:...
In this paper, we propose a Spatial Modulation (SM) with full diversity for 4 transmit antennas, called DS-SM, by designing SC codewords and incorporating them Diagonal Space Time Block Code. Similar to the conventional SM scheme, proposed scheme only activates an antenna element at time signal transmission. However, it is different from in that able achieve diversity. order attain low detection complexity, ML detector based on sphere decoding presented. Computer simulation shows DS-SM...
Background May-Thurner syndrome (MTS) is a continuous pathological change of the left common iliac vein intraluminal wall due to compression between right artery and lumbar vertebra, with clinical signs compromised venous drainage leg, which eventually leads development left-sided deep thrombosis (DVT). Purpose To analyze correlation vessel geometry probability DVT in patients MTS. Material Methods This study consists two age-matched female groups: (n = 21) control 28). Iliac geometry,...
In this paper, a new Space-Time Block Coded Spatial Modulation (SM) scheme based on the Golden Code, called (GC-SM), is proposed and analyzed. This still keeps some main benefits of Code by satisfying non-vanishing Space Time (STBC) criteria. signal constellation domain, GC-SM spectral efficiency twice that STBC-SM. addition, simulation theoretical results show performance surpasses several SM schemes at same antenna configuration. Furthermore, we study impact channel spatial correlation...
In this paper, we propose a new algorithm to select transmit antennas for precoding in Massive MIMO system. At the Base Station (BS), are divided into subgroups with smaller dimensions. Then, they selected based on evaluation of corresponding channel capacities. The groups, which give best sum capacity, process. To lower complexity antenna selection, adopt Singular Value Decomposition matrices compute After selected, transmitted signal vector is precoded by conventional Zero Forcing (ZF) and...
In this paper, we investigate the combination of linear group precoding with a transmit antenna selection (TA-GS) algorithm based on channel capacity analysis for Massive MIMO systems. Simultaneously, propose low complexity that works selected
Abnormal connections between systemic and pulmonary vascular systems are rare conditions have been mostly documented in the pediatric population. We report a case of type B isolated arterial malinosculation an adult. The patient's chief complaint was intermittent hemoptysis during physical exertion. He had dual supply from anomalous artery to left lower lobe venous drainage through vein. bronchial connection appeared normal. fistula identified on chest computed tomography treated...
Approximately 3 dB Signal-to-Noise Ratio (SNR) loss is always paid with conventional Differential Spatial Modulation (DSM) as compared to coherent (SM). In this paper, a Multiple-Symbol Detection (MSDD) technique proposed for DSM systems mitigate the due differential detection. The new scheme can greatly narrow performance gap by extending observation interval decoding. uses maximum-likelihood sequence detection instead of traditional symbol-by-symbol detection, and carried out on slow, flat...
This paper proposes a novel combined spatial and amplitude-phase modulation (APM) scheme based on the generalize space shift keying (GSSK) system. The so-called GSSK/APM performs two independent modulations using GSSK APM constellations. modulated symbols from modulators are multiplied to generate transmit symbols. With different constellations proposed allows easy control of spectral efficiency compared related multiple antenna systems. In order detect symbols, three detectors maximum...

While digital radiography using energy-integration detectors is starting to replace screen/film radiography, photon-counting will offer even more benefits. A prototype scanned projection (SPR) system for Xe:CH/sub 4/ imaging has been constructed, which combines a Gas Electron Multiplier (GEM) and Microstrip Detector (GMD). The energy deposited by each incident photon can be measured when counting done. Both the GEM GMD are novel gas-filled developed high-luminosity experiments in particle...
