FrontFace (2017)

A head-mounted display (HMD) immerses users in a virtual world, but separates them from outsiders in the real world. We present FrontFace, which is a novel HMD that combines an eye-tracker with a front-facing screen, to lower the communication barrier between HMD users and outsiders. The front-facing screen reveals user attention (e.g., the users eye motions) and user presence in the virtual or real world by displaying the scene in the virtual world or a skin background respectively, enabling eye-contact interactions between the HMD user and the outsiders. FrontFace has the following benefits. Firstly, it communicates the presence of the HMD user to outsiders; secondly, it reveals the player's visual attention by introducing the HMD users originally occluded eye motions, enabling outsiders to make sense of the HMD user's reaction in the virtual world or the real world. Three interactive techniques for the outsiders to initiate communication to HMD users are proposed: they are tap-trigger, hand-gesture trigger, and voice-trigger interactions. A small focus group provided feedback.
A Robust Method for Hand Gesture Segmentation and Recognition Using Forward Spotting Scheme in Conditional Random Fields (2010)

This paper proposes a forward spotting method that handles hand gesture segmentation and recognition simultaneously without time delay. To spot meaningful gestures of numbers (0-9) accurately, a stochastic method for designing a non-gesture model using Conditional Random Fields (CRFs) is proposed without training data. The non-gesture model provides a confidence measures that are used as an adaptive threshold to find the start and the end point of meaningful gestures. Experimental results show that the proposed method can successfully recognize isolated gestures with 96.51% and meaningful gestures with 90.49% reliability.
Immunochemistry of R Lipopolysaccharides of <i>Escherichia coli</i> (1970)

Acapsular (K − ) forms were isolated from Escherichia coli strain E56b (serotype O8 :K27(A): H − ). A number of different R strains were obtained from the K − forms by selection of spontaneous mutants and by phage selection. The lipopolysaccharides of these R strains (consisting of core and lipid A) were subjected to mild acid degradation and, after removal of insoluble lipid A, the mixtures were fractionated by gel chromatography. Results of chemical analyses showed that the core oligosaccharides of different R mutants differed with respect to their sugar constituents as well as to the molar ratios of these constituents. A group of R mutants did not contain phosphate in their core oligosaccharides (P − mutants). Enzyme determinations indicated that one R mutant had a block involving UDP glucose pyrophosphorylase, whereas the enzymes of activation and interconversion of component sugars were intact in the other R mutants. By allelic exchange (mating with S‐form Hfr strains) it could be demonstrated that with one exception the chromosomal site of the SR mutation of all mutants maps close to mtl (mannitol utilization). In Salmonella the rfa locus maps in the same region. All R mutants had an unimpaired ( his ‐linked) rfb locus. The groups of mutants which differed in the sugar composition of their core oligosaccharides could also be differentiated serologically and by their sensitivity to phages. There was serological cross reactivity between the lipopolysaccharides of some R mutants with R mutants of Salmonella minnesota which also have a very incomplete core. It is concluded that the lipopolysaccharides of the R mutants described in this paper have incomplete core structures which result from blocks at successive stages in the synthesis of the coli R1 core. In analogy to Salmonella these E. coli R mutants should, with one exception, be termed rfa type mutants.
An investigation of nonlinear transmission lines and shock waves (1977)

Results of a study carried out on a carefully constructed laboratory model of a nonlinear transmission line are reported. These results are compared with those obtained using a computer model, and the two sets of results are shown to be in close agreement. Furthermore, a detailed study of energy balance associated with shock waves indicates that there is no per se energy loss associated with the shock wave formation and in the limit when the line dissipation (R and G parameters) is reduced to zero the system conserves energy. The observed phenomena are fully accounted for by quantitative consideration of the phenomena in the wake of the shock front. It is shown that the 'energy loss', encountered with the classical model, can be accounted for by the energy stored in the AC component of the oscillations formed in the wake of the shock front.

Contribution of Monocytes to Viral Replication in Macaques during Acute Infection with Simian Immunodeficiency Virus (2007)

Monocytes are known as an alternative target for HIV/SIV infection, but the contribution of monocytes to viral spread in a host is unclear. In this study, CD14 monocytes were monitored in 6 macaques until six weeks postinfection (wpi) with SIVmac239 to evaluate their contribution to viral load. The monocyte count in blood significantly increased with peak viremia at 2 wpi and the expression level of CD14 on monocytes significantly decreased at 1-2 wpi, though the number of CD4(+) T cells was stable in these macaques. The number of CD14 monocytes and the expression level of CD14 on monocytes at 2 wpi were also significantly related to the extent of viremia in plasma. An increased number of monocytes at 2 wpi was associated with a lower postacute viral load, suggesting that monocytes have a role in suppressing the virus. The lower expression level of CD14 in monocytes at 2 wpi was associated with a higher viral load and greater degree of infection of monocytes. This correlation suggests that monocytes with a low level of CD14 may be more susceptible to SIV and may enhance viral replication. The analysis of monocytes in persistently infected macaques revealed that the expression level of CD14 was also significantly low during persistent infection compared with naïve macaques, though the monocyte count was within the normal range. Monocytes may suppress viruses, perhaps by their immune function, during acute infection. However, infection of monocytes may increase the viral load and spread viruses in a host.
Regulation of the Cryptic Sequence-specific DNA-binding Function of p53 by Protein Kinases (1994)

p53 is an allosterically regulated protein with a latent DNA-binding activity. Posttranslational modification of a carboxy-terminal regulatory site in vitro, by casein kinase II and protein kinase C, can activate the sequence-specific DNA-binding function of the wild-type protein. The latent form of p53 is produced in a variety of eukaryotic and prokaryotic cell lines, including E. coli, Sf9 insect cells, and C6 cells, indicating that the activation of p53 in vivo is rate-limiting. In addition, phosphorylation of p53 at the protein kinase C site and activation in vivo correlate with the loss of reactivity of active p53 protein to the carboxy-terminal antibody, PAb421. These results suggest that two highly conserved protein kinases modify polypeptide structure through a common biochemical mechanism and that different enzymatic pathways may channel information into the carboxy-terminal regulatory site of p53, allosterically activating its function as a tumor suppressor.
An Adaptive Load Balancer for Multiprocessor Routers (2006)

By investigating flow-level characteristics of Internet traffic, the authors are able to trace the root of load imbalance in hash-based load-splitting schemes. They model flow popularity distributions as Zipf-like and prove that for typical Internet traffic, a hashing scheme cannot balance workload statistically, not even in the long run. They then develop a novel load-balancing packet scheduler for parallel forwarding systems. The scheduler capitalizes on the nonuniform flow reference pattern and especially the presence of a few high-rate flows in Internet traffic. The authors show that detecting and scheduling these flows can be very effective in balancing workloads among network processors. They introduce an important metric, adaptation disruption, to measure the scheduling efficiency of load-balancing mechanisms in parallel forwarding systems. Because there are relatively few large flows, reassigning them in the load balancer results in little disruption to the states of individual processors. The ideas are validated by simulation results. Finally, the authors discuss the effects on cache performance when classifying flows using two different flow definitions: the destination IP address and the five-tuple. The latter results in finer flow granularity but worse route cache hit rate, which can lead to the degradation of routing table lookup performance.
Efficient reprogramming of adult neural stem cells to monocytes by ectopic expression of a single gene (2010)

Neural stem cells have a broad differentiation repertoire during embryonic development and can be reprogrammed to pluripotency comparatively easily. We report that adult neural stem cells can be reprogrammed at very high efficiency to monocytes, a differentiated fate of an unrelated somatic lineage, by ectopic expression of the Ets transcription factor PU.1. The reprogrammed cells display a marker profile and functional characteristics of monocytes and integrate into tissues after transplantation. The failure to reprogram lineage-committed neural cells to monocytes with PU.1 suggests that neural stem cells are uniquely amenable to reprogramming.
Submicron BiCMOS well design for optimum circuit performance (2003)

The optimization of a submicron BiCMOS well design is described. The use of buried layers, a thin intrinsic epi layer, and a double n-well implant creates steeply graded well profiles which result in improved circuit performance due to lower diode capacitance. High contact resistance to the buried n+ layer is avoided by using a novel polysilicon plug contact process which also eliminates lateral n+ diffusion, enabling the base-to-collector design rule to be shrunk by more than 25%.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
102. Overexpression of the Myostatin Antagonist Follistatin in Normal Myoblasts Genetically Modified with a Lentivirus (2005)

Background: Duchenne muscular dystrophy is a severe myopathy caused by the absence of a functional dystrophin in muscles. Transplantation of normal myoblasts is a potential therapy that permits to restore the expression of the dystrophin in transplanted muscles by the formation of hybrid dystrophin positive fibers. However, the success of this approach is compromised by the limited regeneration of damaged muscle. Myostatin, the most powerful inhibitor of muscle growth identified to date, is regulated by different antagonist proteins such as follistatin. Our purpose is to block the myostatin signal in mdx and SCID host mice by the respective transplantation of normal murine and human myoblasts genetically modified with a follistatin lentivirus.
Evaluation of Diet and Life Style in the Etiopathogenesis of Type - 2 Diabetes (2009)

The response to the psychological conditions varies person to person because each has different bodily and psychic constitution. Moreover, stressors play certain role in the development, progression, prognosis and treatment of disease. Stressful life-style affects one's mind and homeostasis of body by several psychosomatic mechanisms. Many psychosomatic disorders are wing sprouted-up with genetic disposition. Type-2 diabetes is one of such diseases, which is adversely affected by disturbed psychological conditions. Survey of 279 type-2 diabetes mellitus patients revealed that majority of the patients were taking milk, followed by curd, cheese, butter etc. Moreover, majority of patients had improper sleep and more than 3/4th female patients had attained menopause with negative mental attitude. These diabetic subjects had worry, depressed mood, anger, fear, apprehension and anxiousness up to a great extent. On Brief Psychiatry Rating Scale, psychological factors affected at various levels include: somatic concern, anxiety, emotional withdrawal, conceptual disorganization, tension, unusual thought content, excitement, disorientation etc. The data reflects that defective diet and disturbed mental health play an important role in etiopathogenesis of diabetes mellitus.

Thyroid Hormone Induced Brown Adipose Tissue and Amelioration of Diabetes in a Patient with Extreme Insulin Resistance (2009)

This case demonstrates the TH effect on BAT activity and volume in this patient and an association between BAT activity and glucose levels in this patient. Because the contribution of TH on skeletal muscle energy expenditure and fuel metabolism was not assessed, an association between BAT activity and glucose homeostasis can only be suggested.
Methylobacterium, a New Genus of Facultatively Methylotrophic Bacteria (1976)

A new genus and a new species of methane-oxidizing bacteria are described. The colonies produced by these bacteria are pink, circular, and convex with entire margins. Cells are gram negative and are normally found singularly with some rosettes. Negative stains indicate polar flagellation. In thin sections, intracytoplasmic membranes, similar to those described as type II in other methylotrophs, were present when the cells were grown with methane. No such membranes were apparent when the cells were grown with the other carbon and energy sources tested. The serine pathway for formaldehyde incorporation is the pathway of C1 metabolism. The deoxyribonucleic acid base composition is 66 mol% guanine plus cytosine. Methylobacterium is proposed as the name for this new genus of rod-shaped, methane-oxidizing bacteria. The specific epithet in the name of the type species, Methylobacterium organophilum sp. nov., denotes the preference of this organism for organic carbon and energy sources more complex than methane. The type strain of M. organophilum is XX (= ATCC 27886). This bacterium differs from all previously described genera and species of methane-oxidizing bacteria in its ability to utilize a variety of organic substrates with carbon-carbon bonds as sources of carbon and energy. The pathways for methane oxidation and the assimilation of one-carbon units are repressed during growth on complex organic substrates.
The first crystal structure of human RNase 6 reveals a novel substrate-binding and cleavage site arrangement (2016)

Human RNase 6 is a cationic secreted protein that belongs to the RNase A superfamily. Its expression is induced in neutrophils and monocytes upon bacterial infection, suggesting a role in host defence. We present here the crystal structure of RNase 6 obtained at 1.72 Å (1 Å=0.1 nm) resolution, which is the first report for the protein 3D structure and thereby setting the basis for functional studies. The structure shows an overall kidney-shaped globular fold shared with the other known family members. Three sulfate anions bound to RNase 6 were found, interacting with residues at the main active site (His(15), His(122) and Gln(14)) and cationic surface-exposed residues (His(36), His(39), Arg(66) and His(67)). Kinetic characterization, together with prediction of protein-nucleotide complexes by molecular dynamics, was applied to analyse the RNase 6 substrate nitrogenous base and phosphate selectivity. Our results reveal that, although RNase 6 is a moderate catalyst in comparison with the pancreatic RNase type, its structure includes lineage-specific features that facilitate its activity towards polymeric nucleotide substrates. In particular, enzyme interactions at the substrate 5' end can provide an endonuclease-type cleavage pattern. Interestingly, the RNase 6 crystal structure revealed a novel secondary active site conformed by the His(36)-His(39) dyad that facilitates the polynucleotide substrate catalysis.

Evaluation of Corn Hybrids Expressing CrylF (Herculex® I Insect Protection) Against Fall Armyworm (Lepidoptera: Noctuidae) in the Southern United States (2008)

Efficacy of two insect-resistant corn hybrids expressing the Cry1 F insecticidal crystal protein of Bacillus thuringiensis var. aizawai Berliner (transformation event TC1507) was evaluated against fall armyworm, Spodoptera frugiperda (J.E. Smith), in three southern U.S. locations. Larval susceptibility was evaluated on CrylF and nonBt field corn, Zea mays L., plants (V3–V12 and R1–R2 stages) in field plots and laboratory studies. Leaf-feeding injury was significantly less and plant height was significantly greater for hybrids containing Cry1 F as compared with nonBt corn hybrids when exposed to natural or artificial fall armyworm infestations. In addition, larval mortality was significantly greater on CrylF corn hybrids compared with that on nonBt hybrids. These results demonstrate that corn hybrids containing CrylF represent an effective plant incorporated insecticidal protein management option for fall armyworm. In environments where fall armyworm may exceed damage thresholds and have to be carefully managed with foliar sprays, utilization of CrylF corn hybrids will allow growers flexibility in planting and an efficient means for managing infestations.
Effects of gonadotrophin deficiency on follicular development in hypogonadal ( <i>hpg</i> ) mice (1986)

The rates of follicle growth and death in GnRH-deficient hypogonadal (hpg) mice and in normal mice were studied using the stochastic compartmental model of follicle dynamics. The rate estimates derived from this model suggest that in normal mice gonadotrophins act at several stages in the development of ovarian follicles. Gonadotrophins appear to regulate the number of follicles beginning to grow by controlling both the rate at which non-growing follicles enter the growing pool and the loss of non-growing follicles to atresia. They also appear to promote the growth of medium-sized follicles by reducing the rate of loss to atresia of these follicles rather than by stimulating growth per se. Furthermore, these data suggest that an intra-ovarian autoregulatory mechanism may exist to control the number of large follicles that are formed.
Functional Properties of Mouse Connexin30.2 Expressed in the Conduction System of the Heart (2005)

Gap junction channels composed of connexin (Cx) 40, Cx43, and Cx45 proteins are known to be necessary for impulse propagation through the heart. Here, we report mouse connexin30.2 (mCx30.2) to be a new cardiac connexin that is expressed mainly in the conduction system of the heart. Antibodies raised to the cytoplasmic loop or the C-terminal regions of mCx30.2 recognized this protein in mouse heart as well as in HeLa cells transfected with wild-type mCx30.2 or mCx30.2 fused with enhanced green fluorescent protein (mCx30.2-EGFP). Immunofluorescence analyses of adult hearts yielded positive signals within the sinoatrial node, atrioventricular node, and A-V bundle of the cardiac conduction system. Dye transfer studies demonstrated that mCx30.2 and mCx30.2-EGFP channels discriminate poorly on the basis of charge, but do not allow permeation of tracers >400 Da. Both mCx30.2 and mCx30.2-EGFP gap junctional channels exhibited weak sensitivity to transjunctional voltage (Vj) and a single channel conductance of approximately 9 pS, which is the lowest among all members of the connexin family measured in HeLa cell transfectants. HeLa mCx30.2-EGFP transfectants when paired with cells expressing Cx40, Cx43, or Cx45 formed functional heterotypic gap junction channels that exhibited low unitary conductances (15 to 18 pS), rectifying open channel I-V relations and asymmetric Vj dependence. The electrical properties of homo- and hetero-typic junctions involving mCx30.2 may contribute to slow propagation velocity in nodal tissues and directional asymmetry of excitation spread in the AV nodal region.
Governing Blockchain-based Token in Indonesia: Legal and Technical Perspective (2020)

In the past decade, blockchain technology has caught the world's attention because of its disruptive nature in various industries. Along with blockchain adoption, blockchain-based token, or more popularly known as the "token", are widely used as a representation of a certain asset. In its development, blockchain innovators continue to encourage the birth of new tokens with more diverse attribution. From the regulator's point of view, the above gave rise to problems in the formation of regulations relating to tokens, mainly on its legality whether token will be determined as currency, securites, or commodity. If regulations still cannot catch up with the gap of technological advancement, this will actually hinder the development of blockchain technology in Indonesia.The token regulatory framework has been designed in several countries which have provided clear distinguishing characteristics for each type of token. However, in Indonesia, the absence of a clear and distinct definition of the types of tokens creates legal uncertainty for stakeholders. Therefore, this paper aims to give clarity to the legality of Blockchain-based tokens in Indonesia.
