When more is less: The other side of artificial intelligence recommendation
2022
Based on consumers' preferences, AI (artificial intelligence) recommendation automatically filters information, which provokes scholars' debate. Supporters believe that by analyzing the consumers' preferences, AI recommendation enables consumers to choose products more quickly and with lower cost. Critics deem that consumers are more easily trapped in information cocoons because of the use of AI recommendation. This reduces the possibility of consumers contacting with a variety of commodities, thus lowering the consumer decision quality. Based on experiments, this paper discusses the moderating role of AI recommendation on the relationship of consumers' preferences and information cocoons. …

Montmorilonīta-antociānu organokompleksi: fizikāli ķīmiskās īpašības un izmantošanas risinājumi
2020
Bakalaura darba ietvaros tika pētīta antociānu interkalācija montmorilonīta struktūrā un veikta iegūtā organokompleksa fizikāli ķīmisko īpašību izpēte inovatīvu un videi draudzīgu materiālu izstrādē. Pētījuma ietvaros izvēlēts rūpnieciski ražots māla minerāls- montmorilonīts, kas tika modificēts ar antociāniem no melnaugļu aroniju ogu (Aronia melanocarpa L.) vai vīnogu (Vitis vinifera) izspiednēm. Antociānu sorbcija uz māla minerāla tika pētīta atkarībā no sorbenta iesvara, sorbāta koncentrācijas, vides pH un temperatūras. Iegūto kompozītmateriālu īpašības tika raksturotas ar Furjē transformācijas infrasarkanās gaismas spektroskopijas (FTIS) un termogravimetrijas analīzes (TGA) metodēm. Ieg…
Video projection mapping e arti performative. Una nuova macchina scenotecnica della visione per generare nuovi spazi aumentati
L’oggetto principale della dissertazione è il video projection mapping, un’applicazione di realtà aumentata che utilizza le tecniche di videoproiezione digitale non su tradizionali schermi di proiezione ma sulla realtà stessa, sugli oggetti fisici, ai quali si adatta e si lega in maniera inestricabile, ibridando il livello fisico-reale e il livello digitale. Al contrario di come spesso è stato considerato, il video projection mapping non è solo un gadget tecnologico dei nostri tempi; quando si ibrida con altri media, come le arti performative, diviene linguaggio metaforico, oltrepassando il suo livello tecnologico per produrre significati, per mediare idee. Considerando il suo uso nello spe…
Apoptosis in human unfertilized oocytes after intracytoplasmic sperm injection
2005
Objective To investigate the presence of programmed cell death in unfertilized oocytes after intracytoplasmic sperm injection (ICSI), assuming that previous apoptotic events could be correlated with the fertilization failure. Design Comparison of the rate of DNA fragmentation in human oocytes at different stages of maturation soon after pick-up (control) and in unfertilized oocytes after ICSI treatment. Setting In vitro fertilization (IVF) laboratory with extensive ICSI experience. Patient(s) Sixty-three patients undergoing assisted fertilization by ICSI. Intervention(s) Terminal deoxynucleotidyl transferase-mediated digoxigenin-dUTP nick-end labeling (TUNEL) assay and anticaspase-3 cleaved…
Designing a graphics processing unit accelerated petaflop capable lattice Boltzmann solver: Read aligned data layouts and asynchronous communication
2016
The lattice Boltzmann method is a well-established numerical approach for complex fluid flow simulations. Recently, general-purpose graphics processing units (GPUs) have become available as high-performance computing resources at large scale. We report on designing and implementing a lattice Boltzmann solver for multi-GPU systems that achieves 1.79 PFLOPS performance on 16,384 GPUs. To achieve this performance, we introduce a GPU compatible version of the so-called bundle data layout and eliminate the halo sites in order to improve data access alignment. Furthermore, we make use of the possibility to overlap data transfer between the host central processing unit and the device GPU with com…
Functional properties of a monoclonal antibody inhibiting the hepatitis C virus RNA-dependent RNA polymerase.
2001
The hepatitis C virus (HCV) RNA-dependent RNA polymerase (RdRp), represented by nonstructural protein 5B (NS5B), has recently emerged as a promising target for antiviral intervention. Here, we describe the isolation, functional characterization, and molecular cloning of a monoclonal antibody (mAb) inhibiting the HCV RdRp. This mAb, designated 5B-12B7, binds with high affinity to a conformational epitope in the palm subdomain of the HCV RdRp and recognizes native NS5B expressed in the context of the entire HCV polyprotein or subgenomic replicons. Complete inhibition of RdRp activity in vitro was observed at equimolar concentrations of NS5B and mAb 5B-12B7, whereas RdRp activities of classica…
SV40 transformed fibroblasts recognize the same 140 kD fibronectin chemotactic fragment as non-transformed cells
1985
SV40-virus-transformed human embryonal fibroblasts show an enhanced chemotactic response to the glycoprotein fibronectin. However, they recognize the same chemotactic active region as non-transformed fibroblasts. The result suggests that an enhancement of chemotaxis by fibroblasts which have been transformed with Simian Virus 40 is due not to the utilization of further chemotactic domains in the molecule, but to an increased sensitivity of the cells to the chemoattractant.
A single tube PCR assay for detecting viruses and their recombinants that cause tomato yellow leaf curl disease in Mediterranean basin
2007
Tomato yellow leaf curl disease (TYLCD) is well known in Mediterranean countries, where it has been causing severe losses in tomato crops for decades. Until recently, two viruses (with several isolates) in the genus Begomovirus, family Geminiviridae, have been associated with the epidemics: Tomato yellow leaf curl virus (TYLCV) and Tomato yellow leaf curl Sardinia virus (TYLCSV). However, recombinants between these, such as Tomato yellow leaf curl Malaga virus (TYLCMalV), are spreading, and new methods for detecting all viruses present in the region are needed. By considering all DNA sequences available of viruses causing TYLCD in the Mediterranean basin, a PCR/RFLP protocol was developed t…
Regularity for nonlinear stochastic games
2015
We establish regularity for functions satisfying a dynamic programming equation, which may arise for example from stochastic games or discretization schemes. Our results can also be utilized in obtaining regularity and existence results for the corresponding partial differential equations. peerReviewed
