The value‐relevance of earnings and operating cash flows during mergers (2004)

This paper examines the value relevance of operating cash flows in consideration of potential weaknesses in earnings quality in the context of a merger. When two firms merge, the earnings stream is altered reflecting the new entity that is created thus, making the prediction of future earnings challenging due to weaknesses in the quality of earnings. The quality of generally accepted accounting principle (GAAP) earnings, has recently been questioned by investors, analysts, and regulators. The difficulty with merged firm earnings has been exacerbated because, prior to June 2001, generally accepted accounting principles (GAAP) allowed firms to account for a merger using either the purchase or the pooling method of accounting. While the pooling method has been eliminated, this paper hypothesizes that difficulties arising from the purchase method of accounting will still exist and will continue to reduce the role of earnings in explaining security returns, and, consequently, the value‐relevance of operating cash flows is expected to increase as investors search for additional means to explain security returns. This paper finds that in the year of the merger, operating cash flows provide valuerelevant information beyond earnings. This finding supports the hypothesis that the quality of earnings in the year of the merger is difficult to interpret, and given this weakness, cash flows can aid in the explanation of abnormal security returns. Additional analyses indicate that the value‐relevance of operating cash flows is positively associated with the purchase method of recording the merger. This result is consistent with operating cash flows assuming a more important role in firm valuation when the difficulties in estimating the merged firm’s earnings are more severe. These findings also suggest that earning’s quality is more value relevant in a non‐merger year than in a merger year.
Learning Active Learning from Data (2017)

In this paper, we suggest a novel data-driven approach to active learning (AL). The key idea is to train a regressor that predicts the expected error reduction for a candidate sample in a particular learning state. By formulating the query selection procedure as a regression problem we are not restricted to working with existing AL heuristics; instead, we learn strategies based on experience from previous AL outcomes. We show that a strategy can be learnt either from simple synthetic 2D datasets or from a subset of domain-specific data. Our method yields strategies that work well on real data from a wide range of domains.
Parameter Estimation and Detection of DS-CDMA Signals subject to Multipath Propagation (1995)

In this paper we consider the problem of estimating the propagation delays and relative amplitudes of the transmitted signals as well as detecting the data bits in an asynchronous direct-sequence code division multiple access (DS-CDMA) system operating over a fading channel. A subspace based estimator is proposed for estimating the propagation delays. The path gains and data bits are estimated with minimum mean squared error techniques. Special attention is paid to the near-far problem. 1 Introduction One major problem in a DS-CDMA system is the near-far problem [2] which occurs when different users have dissimilar powers and their code sequences are not perfectly orthogonal. The standard receiver, the matched filter receiver, is known to fail in a near-far environment. Therefore, several near-far resistant receivers have been previously proposed, e.g., [1, 8, 9]. These receivers all assume that the propagation delays of all users are known. The This work was supported in part by t...
NEMO: Future Object Localization Using Noisy Ego Priors (2022)

Predicting the future trajectory of agents from visual observations is an important problem for realization of safe and effective navigation of autonomous systems in dynamic environments. This paper focuses on two important aspects of future trajectory forecast which are particularly relevant for mobile platforms: 1) modeling uncertainty of the predictions, particularly from egocentric views, where uncertainty in the interactive reactions and behaviors of other agents must consider the uncertainty in the ego-motion, and 2) modeling multi-modality nature of the problem, which are particularly prevalent at junctions in urban traffic scenes. To address these problems in a unified approach, we propose NEMO (Noisy Ego MOtion priors for future object localization) for future forecast of agents in the egocentric view. In the proposed approach, a predictive distribution of future forecast is jointly modeled with the uncertainty of predictions. For this, we divide the problem into two tasks: future ego-motion prediction and future object localization. We first model the multi-modal distribution of future ego-motion with uncertainty estimates. The resulting distribution of ego-behavior is used to sample multiple modes of future ego-motion. Then, each modality is used as a prior to understand the interactions between the ego-vehicle and target agent. We predict the multi-modal future locations of the target from individual modes of the ego-vehicle while modeling the uncertainty of the target's behavior. To this end, we extensively evaluate the proposed framework using the publicly available benchmark dataset (HEV-I) supplemented with odometry data from an Inertial Measurement Unit (IMU).
Bitterness of saponins and their content in dry peas (2006)

Abstract The bitterness of a saponin mixture (containing saponin B and DDMP (2,3‐dihydro‐2,5‐dihydroxy‐6‐methyl‐4 H ‐pyran‐4‐one) saponin in a ratio of 1:4) and saponin B obtained from dry peas were established by a trained panel using line scaling. Both saponins were found to be bitter. However, the saponin mixture, and hence DDMP saponin, was found to be significantly more bitter than saponin B. The bitterness perceived correlated with the saponin concentration. In addition to saponin bitterness, the saponin content and composition of 16 dry pea varieties were also investigated. In two varieties, DDMP saponin was the only saponin present whereas, in the rest of the varieties, DDMP saponin was more abundant than saponin B. The pea varieties investigated differed significantly in saponin content. The amounts of DDMP saponin ranged from 0.7 to 1.5 g kg −1 (dry matter), whereas those of saponin B ranged from 0 to 0.4 g kg −1 . As saponins are bitter, pea varieties with lower saponin contents would be preferred for use in food production. Copyright © 2006 Society of Chemical Industry
XIHbox 8: a novel <i>Xenopus</i> homeo protein restricted to a narrow band of endoderm (1989)

We report the isolation of a new homeobox gene from Xenopus laevis genomic DNA. The homeodomain sequence is highly diverged from the prototype Antennapedia sequence, and contains a unique histidine residue in the helix that binds to DNA. The homeodomain is followed by a 65 amino acid carboxyterminal domain, the longest found to date in any vertebrate homeobox gene. We have raised specific antibodies against an XlHbox 8-beta-gal fusion protein to determine the spatial and temporal expression of this gene. The nuclear protein first appears in a narrow band of the endoderm at stage 33 and develops into expression within the epithelial cells of the pancreatic anlagen and duodenum. Expression within the pancreatic epithelium persists into the adult frog. This unprecedented restriction to an anteroposterior band of the endoderm suggests that vertebrate homeobox genes might be involved in specifying positional information not only in the neuroectoderm and mesoderm, but also in the endoderm. Our data suggest that XlHbox 8 may therefore represent the first member of a new class of position-dependent transcription factors affecting endodermal differentiation.
The Circulating Inactive Form of Matrix Gla Protein Is a Surrogate Marker for Vascular Calcification in Chronic Kidney Disease (2010)

Plasma dp-ucMGP increased progressively in a CKD setting and was associated with the severity of aortic calcification. Plasma dp-ucMGP could thus be a surrogate marker for vascular calcification in CKD.
High Performance Microaccelerometer with Wafer-level Hermetic Packaged Sensing Element and Continuous-time BiCMOS Interface Circuit (2006)

A microaccelerometer with highly reliable, wafer-level packaged MEMS sensing element and fully differential, continuous time, low noise, BiCMOS interface circuit is fabricated. The MEMS sensing element is fabricated on a (111)-oriented SOI wafer by using the SBM (Sacrificial/Bulk Micromachining) process. To protect the silicon structure of the sensing element and enhance the reliability, a wafer level hermetic packaging process is performed by using a silicon-glass anodic bonding process. The interface circuit is fabricated using 0.8 µm BiCMOS process. The capacitance change of the MEMS sensing element is amplified by the continuous-time, fully-differential transconductance input amplifier. A chopper-stabilization architecture is adopted to reduce low-frequency noise including 1/f noise. The fabricated microaccelerometer has the total noise equivalent acceleration of 0.89 µg/√Hz, the bias instability of 490 µg, the input range of ±10 g, and the output nonlinearity of ±0.5 %FSO.
Effect of Surfactant Polyvinyl Pyrrolidone on the Properties of Microporous Carbon Nanospheres Reinforced Magnesium Matrix Composites (2020)

Microporous carbon nanospheres (PCNS)-reinforced magnesium (Mg) composites were prepared using polyvinyl pyrrolidone (PVP) as surfactant and PCNS as reinforcement. The influence of PVP treatment and the effectiveness of PCNS on the mechanical properties of Mg-based composites were investigated. The results show that the PCNS can enhance the properties of the Mg matrix. Moreover, the PVP can effectively improve the dispersion of PCNS in the Mg matrix but had a negative influence on the tensile properties of composites. The MgO films with high tensile strength were produced between matrix and reinforcement after removing PVP, which effectively promotes the interface compatibility and improves the properties of the composite. The tensile yield strength and specific strength of PCNS-reinforced Mg matrix composite exhibited 177 MPa and 102.4 × 103 N∙m/kg, respectively, which were 77% and 78% higher than those of the Mg matrix.
Ministry and the Holy Spirit in Luke-Acts (2004)

At first glance, it is difficult to imagine a more obvious block of Scripture in which to discuss the relationship of ministry to the activity of the Holy Spirit.After all, Acts is often called "Acts of the Holy Spirit."In our Restoration heritage, Acts is the most read, most authoritative text in the New Testament for prescribing the goals and practices of ministry.Yet, the reality for many of us in church experience is a profound disconnect between the activity of the Spirit as described in Acts and the prescriptive way of reading and appropriating practical ministry methods and models.For a variety of reasons, we have been capable of describing the activity of the Spirit in Acts, but incapable of bringing the Holy Spirit with us across the hermeneutical bridge from the first century to the twenty-first.Some of that can be laid at the feet of the overdone rationalism received through our forefathers who could argue by the mid-19th century that any active participation of the Holy Spirit in our world ended with the completion of the New Testament.'Thus, whereas we could accurately describe the importance and function of the Holy Spirit in ministry in the earliest days of the Church, such activity was only an ancient artifact for our present setting.Patterns of ministry to be followed had to do with human behaviors, not Godhead activity.Further compromising an effort to speak of ministry in relation to Luke-Acts, not just Acts, was a covenantal approach to all of Scripture that divided the voice of canonical authority into three sections: Patriarchal, Mosaical, and Christian.This set of judicial divides led many to the conclusion that the relevant body of Scripture for ministry in the Christian community does not begin until the second chapter of Acts at Pentecost.Regardless of the literary connections made by the author of Luke and Acts, there is a covenantal separation that functionally eliminated volume one from ministry appropriation.Thus, there is the great irony of our dependence on the story of Jesus in the Gospels and our complete independence from the story of Jesus for practicing ministry.This divide is further compounded in obvious ways, both in ancient history and our more recent efforts to teach Scripture.One must face the reality of the order of Scripture that comes to us and the distinct separation of Luke and Acts formed by the position of the Gospel of John.Luke "belongs" with the gospels accounts, particularly the synoptic partners Matthew and Mark.Acts of the Apostles "belongs" with the other teachings of the apostles in the Epistles.For decades, our sister Christian colleges and universities have taught New
FeAl underlayers for CoCrPt thin film longitudinal media (1997)

B2 ordered FeAl films with a small, uniform grain size have been produced by rf diode sputter deposition on glass substrates. CoCrPt films grown on FeAl underlayers were found to have the (101̄0) lamellar texture. The in-plane coercivities (Hc) of the CoCrPt/FeAl films are comparable to those of the CoCrPt/Cr films and they can be further improved by inserting a thin Cr intermediate layer between the CoCrPt and the FeAl layers. By employing a MgO seed layer or a (002) textured Cr seed layer, (001) textured FeAl can be obtained. However, the (001) FeAl underlayer only induces a weak (112̄0) textured CoCrPt. Thus no improvement in Hc over those produced on unseeded FeAl underlayers was observed.

The Search for New Fragrance Ingredients for Functional Perfumery (2004)

Functional perfumery is an integral part of the fragrance business. It demands that the ingredients chosen for compounding withstand the aggressive nature of some of the bases used for soaps, detergents, softeners, bleach, and personal-care products. The synthetic efforts in this area reported in this short personal account, presented in a talk at the RSC/SCI conference Flavours & Fragrances 2004 (Manchester), have resulted in the discovery of the two new proprietary molecules Fleuranil (5/6) and Khusinil (7), which fulfill the criteria of functional perfumery. The structure-odor relationships of several analogs of Fleuranil and Khusinil prepared in the course of these investigations are also presented.
The Domestic and Geopolitical Ramifications of the Vietnam War on South Korea (2021)

The Vietnam War is a widely examined topic in the field of international relations. However, it is often viewed in terms of the strategic triangle between the United States, China, and the Soviet Union, instead of their allies. While the atrocities committed by the United States in the Vietnam War are often condemned and scrutinized in English literature, those of South Korea, their closest ally, remain less so. This essay outlines the South Korean government's political, economic, and ideological reasons for supporting the United States in Vietnam, the positive and negative consequences of this support, and the atrocities Korean troops committed against Vietnamese civilians. It argues that the legacy of the Vietnam War in South Korea is characterized by denial and neglect to this day. This essay finds that denial and neglect were experienced not only in Vietnam, but also in South Korea by veterans and the Korean government.
Design considerations and performance characteristics of high concentration point-focussing photovoltaic modules (1984)

Through the auspices of the Department of Energy, the Fresnel lens point-focussing photovoltaic module has evolved into a commercially available, high efficiency low cost option for converting solar energy into electricity. The 15.4% efficient baseline module is undergoing several design improvements to achieve higher efficiencies at high concentrations and lower cost. A 16.5% module will be available in 1984 and 18% Gallium Arsenide modules in 1985. This paper describes the design details and performance characteristics of the baseline module and the design improvements.
EGF potentiated oncogenesis requires a tissue transglutaminase-dependent signaling pathway leading to Src activation (2010)

EGF receptor (EGFR) signaling in human cancers elicits changes in protein-expression patterns that are crucial for potentiating tumor growth. Identifying those proteins with expression regulated by the EGFR and determining how they contribute to malignancy is fundamental for the development of more effective strategies to treat cancer. Here, we show that tissue transglutaminase (tTG) is one such protein. EGF up-regulates tTG expression in human breast-cancer cells, and knock-downs of tTG or the treatment of breast cancer cells with a tTG inhibitor blocks their EGF-stimulated anchorage-independent growth. We further show that the combined actions of Ras and Cdc42, leading to the activation of PI 3-kinase and NFkappaB, provide a mechanism by which EGF can up-regulate tTG in breast-cancer cells. Moreover, overexpression of wild-type tTG, but not its transamidation-defective counterpart, fully mimics the growth advantages afforded by EGF to these cancer cells. Surprisingly, the tTG-promoted growth of breast-cancer cells is dependent on its ability to activate the Src tyrosine kinase as an outcome of a complex formed between tTG and the breast-cancer marker and intermediate filament protein keratin-19. These findings identify tTG as a key participant in an EGFR/Src-signaling pathway in breast-cancer cells and a potential target for inhibiting EGFR-promoted tumor progression.
DC-link capacitor reduction of a controlled rectifier supplying N inverter-motor drive systems by compensating the load variations (2004)

This paper deals with the compensations of the load variations in the control of DC-link voltage of the cascade of one rectifier-N inverter motor drive systems. The objective is to reduce the capacitance of the DC-link capacitors without affecting the stability of the DC-voltage control; so, the rectifier controllers should anticipate the load variation of the N inverter-motor drive systems. This is achieved by introducing compensating structures in the rectifier controllers; then, the DC-link voltage becomes almost insensitive to the load variations. This makes possible to design independently the controllers of the controlled rectifier from those of the inverter-motor assemblies. The presented simulation results validate the efficiency of the proposed methods.
Toxoplasma gondii oocyst survival under defined temperatures. (1998)

The survival of sporulated Toxoplasma gondii oocysts in water at -10 C to 70 C for various periods was investigated. Infectivity of T. gondii was tested by bioassay in mice. There was no marked loss of infectivity of oocysts stored at 10 C, 15 C, 20 C, and 25 C for 200 days, whereas there was a 100-fold loss of infectivity of oocysts stored at 30 C for 107 days. Oocysts stored at 35 C were infective for 32 days but not 62 days, at 40 C oocysts were infective for 9 days but not 28 days, at 45 C, oocysts were infective for 1 day but not 2 days, at 50 C oocysts were infective for 1 hr but not 2 hr. At 55 C and 60 C oocysts were rendered noninfective in 2 and 1 min, respectively. Oocysts remained infective up to 54 mo at 4 C and there was no loss of infectivity in oocysts stored for 106 days at -5 C and at -10 C and for 13 mo at 0 C.
The Action of α‐Mannosidase from <i>Oerskovia</i> sp. on the Mannose‐Rich O‐Linked Sugar Chains of Glycoproteins (1997)

Alpha-mannosidase was isolated from the culture liquid of Oerskovia sp. The purified enzyme had a molecular mass of 480 kDa and comprises four identical subunits. The enzyme cleaves bonds in side chains of yeast mannan (Km = 0.08 mM, k(cat) = 1.02 micromol x min(-1) x mg(-1)) and reveals a low activity towards p-nitrophenyl alpha-D-mannopyranoside. The alpha-mannosidase is a Ca2+-dependent enzyme and is inhibited by EDTA. The enzyme possess no endo-mannosidase activity releasing only mannose in the reaction with the inversion of anomeric configuration and could be classified as exo-alpha-mannanase. The enzyme revealed a high deglycosylating activity towards the short mannose-rich O-linked carbohydrate chains of glycoproteins.
Deficiency of PAR4 Attenuates Cerebral Ischemia/Reperfusion Injury in Mice (2010)

Stroke is the third leading cause of death in the USA. Antithrombotic therapy targeting platelet activation is one of the treatments for ischemic stroke. Here we investigate the role of one of the thrombin receptors, protease-activated receptor 4 (PAR4), in a mouse transient middle cerebral artery occlusion (MCAO) model. After a 60 min MCAO and 23 h reperfusion, leukocyte and platelet rolling and adhesion on cerebral venules, blood-brain barrier (BBB) permeability, and cerebral edema were compared in PAR4-deficient mice and wild-type mice. Cerebral infarction volume and neuronal death were also measured. PAR4-/- mice had more than an 80% reduction of infarct volume and significantly improved neurologic and motor function compared with wild-type mice after MCAO. Furthermore, deficiency of PAR4 significantly inhibits the rolling and adhesion of both platelets and leukocytes after MCAO. BBB disruption and cerebral edema were also attenuated in PAR4-/- mice compared with wild-type animals. The results of this investigation indicate that deficiency of PAR4 protects mice from cerebral ischemia/reperfusion (I/R) injury, partially through inhibition of platelet activation and attenuation of microvascular inflammation.

Robust speaker localization using a microphone array (2000)

This paper presents a speaker localization system using a microphone array. The array is operated as a steered lter-and-sum beamformer implemented as a summed correlator. In particular, we emphasize the use of a speech pause detector to improve the robustness of the speaker localization system by avoiding erroneous position estimates when no speech signal is present. Simulation results and measurements show that speech pause detection improves the overall system performance considerably. 1 Introduction For acoustic speaker localization, we use a number of spatially distributed microphone sensors to capture incoming sound waves. If the amplitude gradient across the microphone array is negligible, the time delays between dierent microphone signals can be expressed in terms of the unknown source location parameters. Speaker localization is related to the classical sonar target detection problem already described in [1, 2]. However, these early references are not directly applicable to...
