Implementación de una línea de evaluación para subproductos agroindustriales como sustrato para la producción de bioetanol. Presacarificación-sacarificación/fermentación simultánea (2011)

The study of alternative routes with better efficiency and low costs is the focus of study in Bioethanol nowadays. For this reason, in this paper we use two kind of filamentous fungi; Trichoderma harzianum and Pleurotus ostreatus, cultivating them in different kind of residual sustrates; as grape pomace, sawdast and sunflower cake provided by national industries, to establish an evaluation system for the the alcohol production process by lignocellulitic microorganisms. In this study, we contemplate three assays; a Presaccharification assay to reduce the saccharification time by predigesting the substrates; an enzymatic saccharification assay using the cellulases produced by the semi solid fermentation of the presaccharification process, and a fermentation assay which involved a thermostable microorganism; Kluyveromyces marxianus (NRRL Y-665) for a simultaneous Saccharification and Fermentation assay. From the results we could conclude that the system used is suitable for the production of reducing sugars and alcohol. Comparative studies using different substrates demonstrate that there is a great use of reducing sugars when the matrix is grape pomace or sunflower cake, roughly a 50%. The subproducts&nbsp; from presaccharification can affect the microorganisms and act as inhibitors of the process, which makes critical the study of this degradation products and how to reduce them . Finally, we can conclude that this system is effective for biomass storage in a stable way and in the same presaccharification process.
Study on dynamic mechanical properties of two rocks under SHPB experiment (2012)

The dynamic mechanical properties of amphibolites and sandstone are studied by using the 100-mm-diameter split Hopkinson pressure bar(SHPB) apparatus.And the regulations of the dynamic mechanical properties of these two rocks which are caused by the strain rate are illustrated.The experimental results show that the dynamic compress strength,the dynamic strength increase factor of amphibolites and sandstone raise with the strain rate increasing,but sandstones are more sensitive than amphibolite when the strain rate changes.The failure configurations of the sandstone specimens present a radial stretch breakage mode that the outer circle peels off in the low strain rate,but the amphibolite present an axial cleaving mode.The sandstone appear to crushing mode but the amphibolite appear to smashing mode in the high strain rate.The research conclusions can provide reference for analyzing the dynamic mechanical behavior of other kinds of brittle materials.
Insect Diuretic Peptides: Structures, Evolution and Actions (1998)

Diuretic peptides stimulate primary urine production by insect Malpighian tubules and, along with antidiuretic hormones, regulate water loss from the excretory system. There are two structurally distinct families of diuretic peptides. CRF-related diuretic peptides belong to the vertebrate CRF/sauvagine/urotensin I/urocortin superfamily. They increase urine production via a cyclic AMPdependent mechanism, and there is evidence for one of them (Lom-DH) having a hormonal function in the control of post-feeding diuresis in locusts. Related peptides appear to trigger post-eclosion diuresis in moths. The insect kinins act via a Ca 2+ -dependent mechanism to stimulate urine production. They are found in hemolymph at levels sufficient to stimulate tubule secretion, but their role in the control of diuresis in vivo has still to be defined. In locusts, these two classes of diuretic peptide act synergistically to accelerate tubule secretion, which may be of physiological relevance. Indeed, synergism may be the norm in controlling tubule secretion, and can involve both neuropeptides and biogenic amines (notably serotonin). Although other diuretic peptides have been identified, their role as circulating hormones has yet to be established.
A study on FBAR Filters reconfiguration (2005)

This paper presents the possibilities to reconfigure the Film Bulk Acoustic Resonator (FBAR) Filters. We propose the addition of passive elements (L, C) to the FBAR. An augmentation of 35% to the bandwidth is found when adding inductances, and a reduction of 32% is established when using capacitances. Also, we propose a new reconfiguration technique for FBARs filters using RF-MEMS switches. We detail this new reconfiguration technique, showing an example of a reconfigurable FBAR filter for operation in the W-LAN 802.11b/g (2.4-2.48 GHz) and in the W-CDMA (2.11-2.17 GHz) communication standards.
Experimental demonstration of nullforming from a fully wireless distributed array (2017)

We consider distributed nullforming using an array of wireless transmitters that coordinate their transmissions to achieve destructive interference at a designated receiver. We describe the first experimental demonstration of distributed nullforming to a target receiver from an array of three distributed transmitters using (mostly) off-the-shelf hardware and simple and standard signal processing techniques. We are motivated by the goal of using distributed arrays to achieve increased spectrum reuse through interference cancellation. Our results show interference suppression in excess of 25dB over uncoordinated transmission. We build on our recent experimental demonstration of beamforming from a distributed antenna array after estimating and compensate for the combined effects of unknown propagation channels, hardware mismatches and clock drifts between the array nodes. The transmitters do not share clocks or have any wired back channels. They coordinate achieve nullforming entirely using in-band wireless message exchanges. Thus these methods can be implemented on portable mobile devices rather than being limited to Base Stations.
Active End-Effector Pose Selection for Tactile Object Recognition\n through Monte Carlo Tree Search (2017)

This paper considers the problem of active object recognition using touch\nonly. The focus is on adaptively selecting a sequence of wrist poses that\nachieves accurate recognition by enclosure grasps. It seeks to minimize the\nnumber of touches and maximize recognition confidence. The actions are\nformulated as wrist poses relative to each other, making the algorithm\nindependent of absolute workspace coordinates. The optimal sequence is\napproximated by Monte Carlo tree search. We demonstrate results in a physics\nengine and on a real robot. In the physics engine, most object instances were\nrecognized in at most 16 grasps. On a real robot, our method recognized objects\nin 2--9 grasps and outperformed a greedy baseline.\n

Ocena okresu wegetacyjnego na Lubelszczyźnie w latach 1951–1990. II. Klasyfikacja dat końca (2004)

W pracy dokonano analizy częstości występowania na Lubelszczyźnie dat końca okresu wegetacyjnego w określonych przedziałach czasowych. Do wyznaczenia dat końca zastosowano metodę Huculaka i Makowca, w której wykorzystano wartości średniej dobowej temperatury powietrza z lat 1951–1990. Dane te pochodzą z zasobów archiwalnych Katedry Agrometeorologii Akademii Rolniczej w Lublinie i dotyczą 10 stacji. Otrzymane daty końca okresu wegetacyjnego zgrupowano następnie w pięciu szeregach rozdzielczych, których granice ustanowiono na podstawie obliczonego dla badanej próby odchylenia standardowego (δ ≈ 11 dni) i średniej daty końca okresu wegetacyjnego przypadającej na 3 listopada.&#x0D; Stwierdzono, że na Lubelszczyźnie zmienność czasowa dat końca okresu wegetacyjnego jest mniejsza od dat początku. Częściej pojawiają się terminy wczesne, a na Nizinie Południowopodlaskiej, Polesiu Podlaskim, Roztoczu, Polesiu Wołyńskim występują również daty końca sezonu anomalnie wczesne (klasa A). Natomiast wzdłuż doliny Wisły, w pasie od Sandomierza po Puławy, daty końca stwierdzono tylko w trzech przedziałach czasowych. Cechuje ten obszar najmniejszy stopień zróżnicowania terminów i większa częstość dat późnych. Z gospodarczego punktu widzenia walory klimatyczne tej części Lubelszczyzny są korzystniejsze, gdyż zmniejszają ryzyko uprawy roślin ciepłolubnych, warzywniczych i sadowniczych, co znajduje potwierdzenie w rzeczywistej produkcji rolnej tych terenów. Analizowana próba dat końca okresu wegetacyjnego sugeruje typową dla klimatu przejściowego Polski zmienność czasową tych terminów. Jednak brak anomalnie późnych dat końca skłania do wnioskowania o tendencji do ich wcześniejszego zakończenia. Wyznaczone klasy z przyporządkowanymi im zakresami dat mogą być wskaźnikami w ocenie dowolnego terminu końca okresu wegetacyjnego oraz stanowić podstawę do odniesienia dla przyszłych analiz porównawczych.
<title>Super-resolution for a UGS system</title> (2005)

The design of an Unattended Ground Sensor (UGS) requires a tradeoff between cost and performance. For designs using a low cost IR microbolometer an array size of 160x120 pixels is a cost effective solution. However, this array size has limited resolving capability. Our goal is to make the best use of the available pixel information from this sensor. There are many reports describing super-resolution (SR) processing as a way to improve image resolution. The definition of SR adopted here is a process where a single high resolution image is created from a sequence of low resolution sub-pixel shifted images. The authors demonstrate the implementation of one SR algorithm from the literature and its benefits to UGS systems using both IR and visible imagery. We describe a software application where the analyst can input a low resolution image frame sequence to produce a high resolution output. The frame sequence can be of a globally shifted frame sequence, a static scene with moving objects or both.
A Versatile Polymer Micelle Drug Delivery System for Encapsulation and In Vivo Stabilization of Hydrophobic Anticancer Drugs (2012)

Chemotherapeutic drugs are widely used for the treatment of cancer; however, use of these drugs is often associated with patient toxicity and poor tumor delivery. Micellar drug carriers offer a promising approach for formulating and achieving improved delivery of hydrophobic chemotherapeutic drugs; however, conventional micelles do not have long-term stability in complex biological environments such as plasma. To address this problem, a novel triblock copolymer has been developed to encapsulate several different hydrophobic drugs into stable polymer micelles. These micelles have been engineered to be stable at low concentrations even in complex biological fluids, and to release cargo in response to low pH environments, such as in the tumor microenvironment or in tumor cell endosomes. The particle sizes of drugs encapsulated ranged between 30-80 nm, with no relationship to the hydrophobicity of the drug. Stabilization of the micelles below the critical micelle concentration was demonstrated using a pH-reversible crosslinking mechanism, with proof-of-concept demonstrated in both in vitro and in vivo models. Described herein is polymer micelle drug delivery system that enables encapsulation and stabilization of a wide variety of chemotherapeutic drugs in a single platform.
Tuning the Fano Resonance with an Intruder Continuum (2014)

Through a combination of experiment and theory we establish the possibility of achieving strong tuning of Fano resonances (FRs), by allowing their usual two-path geometry to interfere with an additional, "intruder", continuum. As the coupling strength to this intruder is varied, we predict strong modulations of the resonance line shape that, in principle at least, may exceed the amplitude of the original FR itself. For a proof-of-concept demonstration of this phenomenon, we construct a nanoscale interferometer from nonlocally coupled quantum point contacts and utilize the unique features of their density of states to realize the intruder. External control of the intruder coupling is enabled by means of an applied magnetic field, in the presence of which we demonstrate the predicted distortions of the FR. This general scheme for resonant control should be broadly applicable to a variety of wave-based systems, opening up the possibility of new applications in areas such as chemical and biological sensing and secure communications.
Towards a modeling and analysis environment for industrial IoT systems (2021)

The development of Industrial Internet of Things systems (IIoT) requires tools robust enough to cope with the complexity and heterogeneity of such systems, which are supposed to work in safety-critical conditions. The availability of methodologies to support early analysis, verification, and validation is still an open issue in the research community. The early real-time schedulability analysis can help quantify to what extent the desired system's timing performance can eventually be achieved. In this paper, we present CHESSIoT, a model-driven environment to support the design and analysis of industrial IoT systems. CHESSIoT follows a multi-view, component-based modelling approach with a comprehensive way to perform event-based modelling on system components for code generation purposes employing an intermediate ThingML model. To showcase the capability of the extension, we have designed and analysed an Industrial real-time safety use case.
Human keratinocyte growth factor effects in a porcine model of epidermal wound healing. (1993)

Keratinocyte growth factor (KGF) is a member of the fibroblast growth factor (FGF) family (hence the alternative designation FGF-7). It is produced by stromal cells, but acts as a mitogen for epithelial cells. We examined the effects of topically applied KGF on healing of wounds in a porcine model. In partial-thickness wounds, KGF stimulated the rate of reepithelialization (p < 0.0002), associated with a thickening of the epidermis (p < 0.0001). Epidermis from KGF-treated full-thickness wound sites was significantly thicker (0.31 +/- 0.22 mm) compared with mirror image control sites (0.18 +/- 0.12 mm) (p < 0.0001). Moreover, the majority (77%) of KGF-treated wounds exhibited epidermis with a deep rete ridge pattern as compared with control sites. These effects were observed as early as 14 d and persisted for at least 4 wk. KGF treatment also increased the number of serrated basal cells associated with increased deposition of collagen fibers in the superficial dermis adjacent to the acanthotic epidermis. Electron microscopy revealed better developed hemidesmosomes associated with thicker bundles of tonofilaments in the serrated cells. The pattern of epidermal thickening observed in KGF-treated wounds resembled psoriasis. Psoriasis is a disease associated with epidermal thickening, parakeratosis as well as hyperproliferation that extends beyond the basal layer. In striking contrast to psoriasis, KGF-treated wounds exhibited normal orthokeratotic maturation, and proliferation was localized to the basal cells. Our present findings have significant implications concerning the role of KGF as a paracrine modulator of epidermal proliferation and differentiation.
Study on time of adding calcium salt during crystallization process for zeolites containing calcium. (1988)

For the zeolites containing calcium, which are superior catalysts in high temperature MTO conversion, the effect of the time of adding calcium salt during the crystallization process on the physical properties and the catalytic performance was studied. It was found that large amounts of calcium were contained in the zeolite when calcium salt was added before or during the crystallization, while calcium was hardly done after the completion of it. It indicated that there were at least two kinds of modification states of the acid sites with calcium, because calcium contained by the addition of calcium salt before the crystallization was hardly ion-exchanged with potassium ions, while calcium during the crystallization can be done. Further, it was confirmed by methanol conversion that the amounts of calcium contained affected the yields of ethylene and propylene.
Pooling Samples: the Key to Sensitive, Specific and Cost-effective Genetic Diagnosis of Chlamydia trachomatis in Low-Resource Countries (2007)

The aims of this study were to compare the performance characteristics and cost-effectiveness of pooling endocervical samples for screening and diagnosis of Chlamydia trachomatis, and to investigate the prevalence of C. trachomatis infection in women in Leningrad Oblast, Russia. A total of 1500 endocervical samples were tested individually and when pooled in groups of 5 and 10 samples, respectively. A previously evaluated in-house diagnostic polymerase chain reaction (PCR) assay was utilized. The sensitivity and specificity of the PCR were not affected by either pooling strategy. The estimated prevalence of genital C. trachomatis infection was 6.6%, 6.1% and 6.0% based on individually tested samples, and pools of 5 and 10, respectively. For diagnosis of individual samples, the pooling strategies resulted in cost savings of 53.3% (5 samples per pool) and 44.0% (10 samples per pool). Pooling samples for PCR detection of C. trachomatis is an accurate and cost-saving approach for diagnosis and large-scale prevalence studies in St Petersburg, Russia.
A Facile and Efficient Direct Aldol Addition of Simple Thioesters (2006)

[reaction: see text] Simple thioesters undergo direct aldol addition to aldehydes in the presence of MgBr(2).OEt(2) and i-Pr(2)NEt using untreated, reagent-grade CH(2)Cl(2) under atmospheric conditions. The reactions proceed extremely rapidly and in excellent yield.
New Frontiers in Ambulatory Assessment (2017)

With the increasing use of smartphone technologies and wearable biosensors, we are currently undergoing what many have termed a “data revolution,” where intensive, multichannel data are passively collected over long time frames. Such procedures are transforming the way psychologists conceptualize research and have the potential to spur important advances in the study of close relationships. This proof-of-concept study from the Couple Mobile Sensing Project, a partnership between psychologists and engineers, combines big data and ambulatory assessment methodologies to study multimodal, microprocesses in couples’ everyday lives. These data collection procedures are designed to test how characteristics of everyday behavioral, physiological, and vocal interactions are integrated within and across individuals. We present two mini-illustrations to show how these data can be synchronized across modalities and partners and can be linked to generalized relationship dimensions. Discussion highlights the potential and challenges of capturing multimodal, multiperson, real-time, naturally occurring social phenomena.
Automatic conversion of sentence-end expressions for utterance characterization of dialogue systems (2015)

Building characters for dialogue agents is important in making the agents more friendly and human-like. To build such characters, utterances suitable for the designated characters are usually manually prepared. However, it is expensive to do this for a large number of utterances for various types of characters. We propose a method for automatically converting system utterances into those that are characteristic of designated personal attributes, such as gender, age and area of residence, to characterize agents. In particular, we focus on converting sentence-end expressions, which are considered to greatly affect personal attributes in Japanese. Conversion is done by (i) automatically collecting conversion candidates from various utterances on the Web (e.g., Twitter postings), and (ii) using syntactic and semantic filters to suppress the generation of ill-formed utterances. Experimental results show that our method can convert approximately 95% of utterances into those that are grammatically and semantically acceptable and approximately 90% of utterances into those that are perceived to be acceptable for designated personal attributes.
Feature Ensemble Plus Sample Selection: Domain Adaptation for Sentiment Classification (2013)

Domain adaptation problems often arise often in the field of sentiment classification. Here, the feature ensemble plus sample selection (SS-FE) approach is proposed, which takes labeling and instance adaptation into account. A feature ensemble (FE) model is first proposed to learn a new labeling function in a feature reweighting manner. Furthermore, a PCA-based sample selection (PCA-SS) method is proposed as an aid to FE. Experimental results show that the proposed SS-FE approach could gain significant improvements, compared to FE or PCA-SS, because of its comprehensive consideration of both labeling adaptation and instance adaptation.
알루미늄 용접을 위한 보호가스 (2013)

In the welding of aluminum, it is important to provide a stable gas shield to exclude not only oxygen, but any sources of hydrogen, from the arc environment. Common sources of hydrogen are humidity in the air around the arc, moisture in the shielding gas, and residual lubricants on the surface of the welding consumable. Since molten aluminum can absorb seventy times more hydrogen than solid aluminum, as the aluminum cools, it releases hydrogen that then becomes trapped in the form of hydrogen bubbles in the solidifying metal.
Nodal is a short-range morphogen with activity that spreads through a relay mechanism in human gastruloids (2022)

Morphogens are signaling molecules that convey positional information and dictate cell fates during development. Although ectopic expression in model organisms suggests that morphogen gradients form through diffusion, little is known about how morphogen gradients are created and interpreted during mammalian embryogenesis due to the combined difficulties of measuring endogenous morphogen levels and observing development in utero. Here we take advantage of a human gastruloid model to visualize endogenous Nodal protein in living cells, during specification of germ layers. We show that Nodal is extremely short range so that Nodal protein is limited to the immediate neighborhood of source cells. Nodal activity spreads through a relay mechanism in which Nodal production induces neighboring cells to transcribe Nodal. We further show that the Nodal inhibitor Lefty, while biochemically capable of long-range diffusion, also acts locally to control the timing of Nodal spread and therefore of mesoderm differentiation during patterning. Our study establishes a paradigm for tissue patterning by an activator-inhibitor pair.
