Financial Computational Intelligence
Artificial intelligence decision support system is always a popular topic in providing the human with an optimized decision recommendation when operating under uncertainty in complex environments. The particular focus of our discussion is to compare different methods of artificial intelligence decision support systems in the investment domain â the goal of investment decision-making is to select an optimal portfolio that satisfies the investorâs objective, or, in other words, to maximize the investment returns under the constraints given by investors. In this study we apply several artificial intelligence systems like Influence Diagram (a special type of Bayesian network), Decision Tree and Neural Network to get experimental comparison analysis to help users to intelligently select the best portfoliArtificial intelligence, neural network, decision tree, bayesian network
Prizadevanje za prikrivanje za druĆŸinske Älane: pomen in vrednotenje konfucijske ideje o »prikrivanju za druĆŸinske Älane« v moderni druĆŸbi
The argument for covering up for family members who had committed offenses was a core part of Confucian thinking, and a topic that has long been controversial. This idea tended to be deemed by traditional Legalist scholars and contemporary law-centered scholars as an outdated approach that compromised legal fairness, and thus should not be accepted by contemporary society. However, it is understood through Honnethâs recognition theory that the âlawâ is in fact merely a principle of recognizing a personâs identity as a member of civil society, and we cannot ignore that man also has an identity of the âfamilyâ relation that is connected to âloveâ. The identity recognition based on the principle of âloveâ is an intrinsic need of humans, and also an essential link in the establishment of an integrated personality. The desire to cover up for a family member is nothing other than an attempt to rebuild an ethics-centered identity recognition, so as to avoid the materialization of humans by âlawsâ.Razprava o prikrivanju za druĆŸinske Älane, ki so storili kaznivo dejanje, je bila v samem jedru konfucijskega razmiĆĄljanja ter ĆŸe dolgo predstavlja sporno temo. Tradicionalni legalistiÄni uÄenjaki ter sodobni raziskovalci zakonov imajo to idejo pogosto za zastarelo ter menijo, da ogroĆŸa legalno praviÄnost, zaradi Äesar je nesprejemljiva za sodobno druĆŸbo. Toda Äe sledimo Honnethovi teoriji prepoznavanja, ki pravi, da je "zakon" le princip prepoznavanja Älovekove identitete v okviru civilne druĆŸbe, potem ne moremo prezreti, da ima Älovek tudi identiteto v okviru druĆŸinskih odnosov, ki je povezana z "ljubeznijo". Prepoznavanje identitete, utemeljene na principu "ljubezni", je notranja Älovekova potreba in bistvena komponenta pri grajenju integrirane osebnosti. Ćœelja po prikrivanju za druĆŸinskega Älana ni tako niÄ drugega kot poskus, da se obnovi prepoznavanje identitete, ki izhaja iz etike, s Äimer se izognemo "zakonsko" utemeljeni materializaciji Äloveka
A Young Girl Reading: Marthaâs Quest through Literature and Realism in Martha Quest
This paper examines the young heroineâs ambivalent relationship with books in Doris Lessingâs coming-of-age novel Martha Quest. Martha, a young British girl growing up in the British colony of Southern Rhodesia (now Zimbabwe) in the wake of World War II, is a voracious young reader who reads extensively in order to make sense of the world in which she is living. Sometimes the books she reads lead her to think critically and challenge the canonical authorities and patriarchal society; however, at times her reading experience is also unsettling and frustrating because the books she reads are mostly produced within a biased system she intends to go beyond. The paper analyzes how Martha relies on books to reshape her national identity and personal life, and how she deals with the discrepancy between the world represented in books and reality in terms of Benedict Andersonâs concept of an âimagined communityâ. Furthermore, this paper also discusses how Marthaâs portrait as a bewildered reader of realist literature mirrors Lessingâs own ambiguous relationship with her realist narratives
Smart Device Cyber Security
In 2007, Apple released the iPhone under the direction of Steve Jobs. At the time people did not realize how revolutionary this invention would be. 13 years later, smartphones and other connected devices have completely permeated American society. According to Pew Research Center, in 2019 81% of Americans owned smartphones and 52% of Americans owned a tablet computer. Smartphones and other smart devices provide a large amount of convenience to their users, but the personal data stored on them presents a huge security risk
Mobilization of Adipose Stromal Cells in Obesity and Cancer by SPARC and its Proteolytic Isoforms
Obesity increases cancer risk and progression as shown by epidemiologic studies. However, the underlying pathophysiology remained unclear. Adipose stromal cells (ASC) are adipose tissue-derived mesenchymal progenitors, abundant in white adipose tissue (WAT). In this study, we show that the ASC pool is expanded in obesity and is associated with promoted tumor growth. Next, by using a chimeric GFP-RFP bone marrow transplant model, we observed higher tumor infiltrating cells with ASC phenotype in obese mice compared to lean. Consistently, systemic circulating ASC frequency is six fold higher in tumor-bearing obese mice compared to lean. The tumor infiltrating cells with ASC phenotype are found to be perivascular, suggesting them being incorporated into vessels as pericytes to support tumor vasculature. We obtained evidence that ASC is mobilized in response to obesity and cancer, however, the mechanisms regulating ASC trafficking are poorly defined. We previously reported that the binding of the matricellular protein SPARC to ÎČ1 integrin on ASC surface induces their motility. Here, we demonstrate that absence of SPARC diminishes ASC capacity to mobilize. As adiposity correlates with circulating SPARC and is the major producer of it, we evaluate SPARC level in distinct adipose depots and identify two SPARC proteolytic isoforms: C-SPARC (lacking the N-terminus) and N-SPARC (lacking the C-terminus), generated in the mesenteric white adipose tissue of obese mice. Both isoforms exhibit distinct ÎČ1 integrin binding capacity. C-SPARC binds to ÎČ1 integrin on ASC, while N-SPARC fails to, but shows to be a potent extracellular matrix (ECM) / integrin interaction blocker and these events are associated with integrin-dependent FAK-ERK signaling and integrin-independent ILK-Akt signaling. We show that both isoforms induce ASC de-adhesion and, acting through different mechanisms, have additive effect in promoting ASC migration
A unique seasonal pattern in dissolved elemental mercury in the South China Sea, a tropical and monsoon-dominated marginal sea

The definitive version was published in Geophysical Research Letters 40 (2013): 167â172, doi:10.1029/2012GL054457.A unique seasonal pattern in dissolved elemental mercury (DEM) was observed in the tropical monsoon-dominated South China Sea (SCS). The DEM concentration varied seasonally, with a high in summer of 160 ± 40âfM (net evasion 580 ± 120âpmolâmâ2âdâ1, nâ=â4) and a low in winter of 60 ± 30âfM (net invasion â180 ± 110, nâ=â4) and showed a positive correlation with sea surface temperature (SST). The elevated DEM concentration in summer appears mainly abiologically driven. In winter, the SCS acts as a sink of atmosphere Hg0 as a result of low SST and high wind of the year, enhanced vertical mixing, and elevated atmospheric gaseous elemental mercury. Annually, the SCS serves as a source of Hg0 to the atmosphere of 300 ± 50âpmolâmâ2âdâ1 (385 ± 64âkmolâHgâyrâ1, ~2.6% of global emission in ~1% of global ocean area), suggesting high regional Hg pollution impacts from the surrounding Mainland (mostly China).Support was provided

Semidefinite programming bounds on the size of entanglement-assisted codeword stabilized quantum codes
In this paper, we explore the application of semidefinite programming to the
realm of quantum codes, specifically focusing on codeword stabilized (CWS)
codes with entanglement assistance. Notably, we utilize the isotropic subgroup
of the CWS group and the set of word operators of a CWS-type quantum code to
derive an upper bound on the minimum distance. Furthermore, this
characterization can be incorporated into the associated distance enumerators,
enabling us to construct semidefinite constraints that lead to SDP bounds on
the minimum distance or size of CWS-type quantum codes. We illustrate several
instances where SDP bounds outperform LP bounds, and there are even cases where
LP fails to yield meaningful results, while SDP consistently provides tight and
relevant bounds. Finally, we also provide interpretations of the Shor-Laflamme
weight enumerators and shadow enumerators for codeword stabilized codes,
enhancing our understanding of quantum codes.Comment: 20 pages, 1 tabl
