Independent component analysis based semi-blind I/Q imbalance compensation for MIMO OFDM systems (2010)

We propose a novel semi-blind compensation scheme for both frequency-dependent and frequencyindependent I/Q imbalance based on independent component analysis (ICA) in multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems, where ICA is applied to compensate for I/Q imbalance and equalize the received signal jointly, without any spectral overhead. A reference signal is embedded in the transmitted signal with little power consumption and no spectral overhead introduced, to enable ambiguity elimination for the ICA output signal at the receiver. Moreover, channel interpolation is incorporated with layered space frequency equalization (LSFE) to enhance the system performance. Simulation results show that the proposed implicit compensation scheme can not only provide a better bit error rate (BER) performance and a higher bandwidth efficiency than the previous training based I/Q imbalance compensation method, but also outperform the ideal case with perfect channel state information (CSI) and no I/Q imbalance, due to additional frequency diversity.
Binding of cadmium and copper(II) ions to oligogalacturonic acids (1983)

The binding of Cu 2+ and Cd 2+ ions to potassium oligogalacturonates of polymerization degree DP 1 to 9 was investigated by ion-specific electrodes and by the metallochromic indicator method. The interaction was evaluated on the basis of degree of association β of cations (M 2+ ) with carboxyl groups of the compounds examined and the single-ion activity coefficients of counterions γ M 2+ . The results were compared with values corresponding to an electrostatic bond of Ca 2+ ions to these oligomers. The Cd 2+ , and especially Cu 2+ ions were bound in a considerable measure already to mono- and oligogalacturonates of a low polymerization degree very probably by a chelate bond. Precipitation of Cu- and Cd-oligogalacturonates takes place at a polymerization degree DP 5 and 8, respectively. Interpretation of results by the multiple equilibria theory evidenced that the Cu 2+ ions were stoichiometrically bound to mono- and oligogalacturonates (one cation to two carboxyl groups) similarly, as with polymeric D-galacturonan. The results revise the early conception concerning the formation of a positively charged complex of Cu 2+ ions (similarly also of Cd 2+ and Pb 2+ ions) with monogalacturonic acid of (MA) + type, where A - is the anion of uronic acid. The results are a contribution to the elucidation of the elimination mechanism of these toxic cations from human body involving the oligomeric fragments of pectin as products of its enzymic degradation in the digestive tract.
Stock Price Manipulation Detection using Generative Adversarial Networks (2018)

We implemented Generative Adversarial Networks (GANs) for detecting abnormal trading behaviors caused by stock price manipulations. Long short-term memory (LSTM) was used as a base structure of our GANs, which learned normal market behaviors in an unsupervised way. After the training, the discriminator network of GANs was used as a detector to discriminate between normal and manipulative trading. Our work is different from the previous work in that we did not use manipulation cases to train the neural networks. Instead, we used normal data to train them, and simulated manipulation cases were only used for testing purposes. The detection system was tested with the trading data from the Stock Exchange of Thailand (SET). It can achieve 68.1% accuracy in detecting pump-and-dump manipulations in unseen market data.

Electroporation of exogenous antigen into the cytosol for antigen processing and class I major histocompatibility complex (MHC) presentation: weak base amines and hypothermia (18°C) inhibit the class I MHC processing pathway (1992)

While endogenous antigens are presented by class I major histocompatibility complex (MHC) molecules, exogenous antigens generally require a means for penetration into the cytosol for processing prior to class I MHC presentation. We have optimized conditions for electroporation as a means to experimentally introduce exogenous antigens into the cytosol, providing a system with a number of advantages for dissecting the class I MHC processing pathway. Presentation was assessed by the response of class I or class II MHC-restricted T hybridoma cells. Essentially instantaneous antigen delivery by electroporation facilitated kinetic analysis of the class I pathway and investigation of the effects of various inhibitors or hypothermic conditions on class I MHC antigen processing. This pathway was inhibited by weak base amines (e.g. chloroquine and NH4Cl), cycloheximide, and hypothermia (18 degrees C, which inhibits certain intracellular vesicular processing pathways). The electroporation technique provides a simple, consistent approach for rapid cytosolic antigen delivery for analysis of class I MHC processing.

Aim to Take Advantage of Various Targeted Tax Credits (2004)

Various location-based and employee-specific tax credits operate beneath the radar of many tax accounting schemes. By failing to detect and act on these credits, businesses are passing up what can amount to significant tax savings. In fact, this family of federal and state tax credits can save employers thousands of dollars per qualified employees, thus having a substantial effect on a business's bottom line. According to the General Accounting Office, only 1 in 800 businesses claim a credit they are due. In the small and medium sized business market (i.e., revenues exceeding $50 million), $4.2 billion in federal and state level tax credits go unclaimed. Location-based and employee-specific state and federal tax credits have been around for a long time. The government created the credits as an incentive to businesses to either hire certain types of people or to establish their businesses in certain geographical areas. Yet less than 1% of businesses in an enterprise zone claim a credit. Why has there been so little participation? The inescapable truth is that the regulations and claim process for enterprise zone tax credits are cumbersome and confusing. Business owners do not know if they qualify or how to claim a credit. There are a lot of tax credits to seek out - over 925 federal, state and local taxes are waiting to be found. Typical businesses that qualify for location-based and employee-specific state and federal tax credits include restaurants, hotels and motels, healthcare providers, independent retailers and chains, light manufacturers and distribution companies, and professional employers organizations - companies with a high percentage of minimum wage to $12 per hour employees. Approximately one in five of new hires in this pay range are eligible for one to the employee-specific state and federal tax credit programs. The solution is a systematic approach to tax credit discovery AND recovery that guarantees you only pay for when you receive the credits - an automated service for accountants, tax attorneys and professionals to implement with their clients. Automated tax credit recovery services directly benefit tax professionals and businesses. Credits can be used quarterly, carried forward up to 20 years or even carried back one year, and are a dollar for dollar reduction in a businesses taxes. Tax credit professionals can offer a no-risk, no-cost service with no additional time or effort, and allow businesses to earn additional income with a value-added, year-round service.
Brain-derived neurotrophic factors and neonatal hypoxic ischemic brain damage (2003)

The hypoxic ischemic brain damage (HIBD) seen in survivors with prenatal or postnatal asphyxia is a major cause of disabilities. There are a lot of methods to intervene HIBD, but no any method can really cure it. More and more evidences show that brain derived neurotrophic factors (BDNF) have beneficial effects on the growth and development of nerve cells. In addition, BDNF can stimulate the nerve cells injured by hypoxia and ischemia to renovate. In this article, in order to provide evidence for clinical application of BDNF in newborns with HIBD, we reviewed the beneficial effects of BDNF on HIBD from the following aspects: ①the mechanisms that BDNF protects the newborns from HIBD;②the effects of BDNF on animal models; ③clinical application potential of BDNF; ④challenges and prospects in clinical pharmacology of BDNF.
Semiotics approach to ‘Strength of Weak Ties’ (2022)

본 연구는 대표적 소셜 네트워크인 ‘페이스북’ 창업과정을 다룬 영화 ‘소셜 네트워크’(The Social Network, 2010)를 그레마스의 행동자 모델과 기호사각형 모델을 활용하여 분석함으로써 ‘약한 유대의 힘’이 가지고 있는 기호학적인 함의와 사회연결망 관점에서 산학협력의 인맥구축에 관한 시사점을 제시하였다. ‘약한 유대의 힘’은 소셜 네트워크의 성장과 확산을 설명하는데 중요한 개념으로 자리 잡고 있지만, 마크 그라노베터의 논문(1973)의 결과는 ‘구직 정보’에 대한 것으로 정보의 속성과 이를 생성하고 전파하는 사람의 관계를 동일시하는가, 분리하는가에 따라 ‘약한 유대’에 대한 영향력이 달라질 수 있다. 그러므로 산학협동 프로그램을 운영할 때도 인맥형성과 정보수집 및 활용 측면에서 약한 유대의 특징을 지니고 있는 소셜 네트워크 활용과 함께 정보공유 측면에서 강한 유대관계인 전통적인 인적 네트워크를 효율적으로 분배하고 활용해야 할 것이다.
Growth of well-defined ZnO microparticles by hydroxide ion (2019)

The morphology of the microcrystalline zinc oxide formed by reaction of zinc salts with sodium hydroxide depends critically on the reaction conditions. To understand this, the nature of the solid product has been probed by scanning electron microcopy (SEM) and X-ray diffraction (XRD) and the concentration of zinc remaining in the solution has been determined at regular intervals throughout the reaction. Two general preparative procedures have been followed. The first, which involves simply heating an aqueous solution containing Zn(NO3)2 (0.025 M) and sodium hydroxide (0.375 M) to 101 uC and maintaining it at that temperature for periods of up to 8 hours, produces star-like microcrystals. The star-like morphology is apparently caused by multiple crystal twinning at the onset of growth, and the size and shape of the microcrystals have been found to be affected by both the reaction stoichiometry and the type of zinc salt ; counterion. In the second method, which produces needles of zinc oxide (lengths up to 6 mm—aspect ratio w6), the reagents are stirred at room temperature for two hours before heating the mixture to 101 oC andmaintaining it at that temperature for up to 24 hours. Pre-stirring allows the formation of Zn(OH)2, which is shown by XRD and SEM to transform to ZnO upon heating.
Automatic diagnosis of student programs in programming learning environments (1999)

This paper describes a method to automate the diagnosis of students &apos; programming errors in programming learning environments. In order to recognize correct students &apos; programs as well as to identify errors in incorrect student programs, programs are represented using an improved de pendence graph representation. The student pro gram is compared with a specimen program (also called a model program) at the semantic level after both are standardized by program transformations. The method is implemented using Smalltalk in SIPLeS-II, an automatic pro gram diagnosis system for Samlltalk program ming learning environments. The system has been tested on approximately 330 student pro grams for various tasks. Experimental results show that, using the method, semantic errors in a student program can be identified rigorously and safely. Semantics-preserving variations in a stu dent program can be eliminated or accommo dated. The tests also show that the system can identify a wide range of errors as well as pro duce indications of the corrections needed. This method is essential for the development of pro gramming learning environments. The tech niques of the improved program dependence graph representation, program standardization by transformations, and semantic level program comparison are also useful in other research fields including program understanding and software maintenance. 1

Envelope tracking power amplifier robust to battery depletion (2010)

A wideband envelope tracking power amplifier, which is robust to battery depletion, is introduced. An integrated boost converter keeps a stable operation of the PA supply modulator. Even at the battery depletion from 4.2 V to 2.8 V, there is no significant degradation of output power and linearity in the power amplifier. Moreover, the efficiency degradation by the additional regulator is minimized for the novel supply modulator architecture proposed in this work. The fabricated 2.535 GHz envelope tracking power amplifier presents max/min power-added efficiencies of 32.3/26.2% for 10 MHz BW 3 GPP LTE standard along the battery voltage from 4.2 V to 2.8 V.
Characteristics of photonic nanojets from ordered microassemblies of dielectric spheres (2016)

Spatially localised light structures (photonic nanojets) formed in the near field of light scattering from an ordered ensemble of single-layer clusters of transparent glass microspheres have been theoretically studied. The main parameters of photonic nanojets (length, width, focal distance and intensity) are calculated based on numerical solution of Maxwell equations, and their behaviour under conditions of interference between neighbouring microparticles is analysed. The degree of manifestation of collective effects during the formation of a nanojet array is found to depend on the spatial structure of the ensemble of microspheres, their size and repetition period. It is found that in some cases, having chosen an appropriate configuration of a microsphere ensemble, one can improve significantly the characteristics of the photonic nanojets formed by this ensemble.
Recent Advances in the Psychopharmacological Treatment of Anxiety Disorders (1988)

The authors review recent progress in the pharmacological treatment of anxiety disorders. Most research within the last five years has focused on panic disorder; the findings include support for the usefulness of imipramine and clomipramine and probably other agents; evidence that the benzodiazepines alprazolam, diazepam, lorazepam, and clonazepam are approximately equally effective as antipanic agents; and high variability in relapse rates after discontinuation of drug treatment. Further work is required to determine whether buspirone and other forthcoming serotonin agonist drugs have a role in treating panic disorder and other anxiety disorders. For generalized anxiety disorder, scientific studies do not support the effectiveness of beta blocker; tricyclics may be potentially useful. Psychopharmacological treatments for social phobia, obsessive-compulsive disorder, and posttraumatic stress disorder are also reviewed.
Glycine N-methyltransferase is a folate binding protein of rat liver cytosol. (1984)

A comparison of the amino acid compositions of one of the folate-binding proteins of rat liver cytosol, folate-binding protein-cytosol II, and that of glycine N-methyltransferase (S-adenosyl-L-methionine:glycine methyltransferase, EC 2.1.1.20) from the same source indicated a great deal of structural homology between the two proteins. Antiserum prepared against the purified folate-binding protein almost completely inactivated the enzyme activity in crude liver cytosol. Purification of glycine N-methyltransferase resulted in the separation of two enzyme species, one that contained bound folate and one that did not. Each species was homogeneous, as judged by NaDodSO4/polyacrylamide gel electrophoresis, and they migrated identically.
Information technology systems in logistics and roles of ERPs (2012)

Chosen business processes and software products should certainly provide suitable and reliable applications for long term. However, because of the sudden improvement and change of modern IT Technology, some solutions become out of date and those should be replaced sooner or later, even if we consider the world of Enterprise Resource Planning systems. One can figure out that business requirements for software change management depend on specific business functions, industry, technologies and so on. This is true for the IT needs of logistics as well. With the existence of supply chain management, strong needs for a solid IT background came to life. These needs cover the fields of data mining, advanced business intelligence tools, and the move towards cloud computing and mobile devices as well. After overviewing some of the basic elements and challenges of supply change management, this paper tries to analyse two widespread ERPs, SAP and Dynamics AX, and compare them from logistics point of view. In this area the need for a long term reliable and supported solution and the need for the latest technology exist parallel. There is only a slight difference in the used technology, but a greater difference in the way business flows are handled.
Dysregulation of <i>CD47</i> and the ligands thrombospondin 1 and 2 in multiple myeloma (2007)

CD47 and thrombospondin 1 and 2 (TSP1 and TSP2) expression were analysed by real-time reverse transcription polymerase chain reaction in fluorescence-activated cell sorted plasma cells (PCs) from patients at consecutive stages of multiple myeloma (MM) development. 80% of MM patients, but only 39% of patients with monoclonal gammopathy of undetermined significance (MGUS) expressed CD47; median expression level increased 10-fold with progression from MGUS to MM. Elevated TSP1/TSP2 levels occurred in bone marrow cultures from MM patients compared with healthy donors. CD47 and TSP1/TSP2 may have a potential role in the pathophysiology of MM, probably in the interaction between MM PCs and the microenvironment.
A Comparison of Queueing, Cluster and Distributed Computing Systems (1994)

Using workstations clusters for distributed computing has become popular with the proliferation of inexpensive, powerful workstations. Workstation clusters offer both a cost effective alternative to batch processing and an easy entry into parallel computing. However, a number of workstations on a network does not constitute a cluster. Cluster management software is necessary to harness the collective computing power. In this paper, we compare a variety of cluster management and queueing systems: COmputing in DIstributed Networked Environments (CODINE), Condor, CONNECT:Queue (formerly NQS/Exec), Distributed Job Manager (DJM), Distributed Queueing System (DQS), Load Balancer, LoadLeveler, Load Sharing Facility (LSF), NC TOOLSET, Network Queueing Environment (NQE), Portable Batch System (PBS), and Task Broker. The systems differ in their design philosophy and implementation. Based on published reports on the different systems and conversations with the developers and vendors, a comparison of the systems is made on the integral issues of clustered computing.
Reading space for new worlds in Jordan Abel’s<i>Un/inhabited</i> (2021)

Nisga’a writer Jordan Abel created Un/inhabited by rearranging and deleting large swathes of ninety-one western novels. Unsurprisingly, then, this poem is largely interpreted as an invitation to readers to join Abel in critically examining the colonial mindset underpinning the western genre. While this alone makes the poem a valuable resource in literary studies classrooms, I look beyond what readings Un/inhabited creates the conditions for to ask what reading practices it affords. The poem’s experimental form presents a challenge to readers as it resists attempts to read using conventional strategies. Taking a cue from the book's title, I ask what happens when readers enter the space of the poem as reader-discoverers, and how they can be helped to engage with it in meaningful ways. Guided by Abel’s decolonial poetics and his play on the metaphor of text as landscape, I draw on Gilles Deleuze and Félix Guattari’s theories of nomadology and smooth, striated, and holey space to suggest that Un/inhabited’s own spaces invite anti-settler, nomadic modes of reading. These render texts porous, undermining their capacity to determine the shape of the worlds they narrate. Approaching texts in this way enables readers to shift from passive recipients of information to world shapers.
Cyber Terrorism Attacks (2007)

Cyber terrorism is the premeditated, politically motivated attacks against information, computer systems, computer programs, and data which result in violence against non-combatant targets by sub-national groups or clandestine agents. The possibilities created for cyber terrorism by the use of technology via the internet are vast. Government computer networks, financial networks, power plants, etc are all possible targets as terrorism may identify these as the most appropriate features to corrupt or disarm in order to cause havoc. Manipulation of systems via software with secret "back doors", theft of classified files, erasing data, re-writing web pages, introducing viruses, etc are just a few examples of how terrorism can penetrate secure systems. This chapter provides a brief overview of previous cyber terrorism attacks and government responses.
