Plant Compound Can Help Prevent Breast Tumor Growth
by VR Sreeraman on August 4, 2012 at 5:29 PM Cancer News - G J E 4
After a study on a mouse model researchers report that a plant compound phenethyl isothiocyanate (PEITC) can help in reducing the growth of breast cancer.
Edible plants are gaining ground as chemo preventative agents. PEITC has shown to be effective as a chemo preventative agent in mice for colon, intestinal, and prostate cancer, by inducing apoptosis.
AdvertisementIn order to determine the efficacy of PEITC in mammary tumors in mice, Shivendra V. Singh, Ph.D., of the University of Pittsburgh Cancer Institute and colleagues, placed mice on two diets: a control diet, and a diet supplemented with PEITC for 29 weeks.
The researchers performed histopathological assessments, and measured the incidence and size of the mammary tumors, along with cell proliferation, apoptosis, and neoangiogenesis, which were determined in tumor sections.
The researchers found that administering PEITC for 29 weeks was linked with a 56.3 percent reduction in mammary carcinoma lesions greater than 2mm.
"Although PEITC administration does not confer complete protection against mammary carcinogenesis, mice placed on the PEITC-supplemented diet, compared with mice placed on the control diet, clearly exhibited suppression of carcinoma progression," the authors write.
PEITC was also well-tolerated. Since chemoprevention trials are both expensive and time-consuming and necessitate years of follow-up, the authors feel that, "The discovery of biomarker(s) associated with exposure and activity is critical for clinical development of promising cancer chemopreventative agents."
This study was able to identify certain biomarkers that may be useful in future clinical investigations.
The authors also point out certain limitations of their study, namely that the results may be different in humans than in mice; also both the relevance of other altered proteins from PEITC and the mechanism by which PEITC causes apoptosis are unclear.
The study was recently published in the Journal of the National Cancer Institute.

It's amazing how many people come into the museum and think the tribe doesn't exist, because of James Fennimore Cooper and 'The Last Mohican,'" said Barbara Allen, Curator of the Stockbridge Historical Collection. "They are amazed to find that there are nearly as many enrolled members of the Stockbridge Munsee as there are people in Stockbridge."
In the 1730s, the Mohicans had left their rich farmlands and fishing grounds along the Hudson and settled in Great Barrington. They agreed to leave their lands in Great Barrington and to settle in Stockbridge, to join a mission settlement with the Rev. John Sergeant, in exchange for a promise that they would not have to move again.
By 1785, the Mohican families in the mission had lost their Stockbridge lands to "settlers." A 1750s document in Allen's collection forced the nation to divide their land into allotments. The nation tradtionally held land collectively — as the Stockbridge Munsee do today, said Sherry White, Tribal Historic Preservation Officer for the Stockbridge Munsee Community Band of Mohican Indians, now based in Wisconsin.
When one man held title to the land, Europeans could more easily take it from him.
"Before that (allotment), the English were unsystematically stealing land," said Stockbridge Police Chief Rich Wilcox, who works with White to preserve places important to her people. "After they set up the proprietorship, they had a system for stealing the land."
In 1785, the Mohicans petitioned the legislature for blankets, a horse and a wagon, and they walked 160 miles to settle alongside the Onieda in New York State. But their ties in the Berkshires have always remained, and they have always been deep, changing — and contemporary.
"People have this idea that when we all moved, we all moved together," White said.
Mohican families must have settled, and Mohican people must have married, all long the way from Massachusetts to Wisconsin, she said.
Allen believes that even "after the people left, if they all left, they came back to visit."
They kept in touch with families who lived here, she said, and came back to see the lands they knew. Wilcox has found references in historical documents to a family who would come back to camp on the land they had once owned and weave and sell baskets to support themselves.
If we could talk to them in their language, we might know how they felt when the sun rose over the mountains on a fall morning.
No one living today speaks the Mohican language, White said, though an effort has begun to teach it in schools, and people speak Munsee, which is similar.
Language shows the way people think, and a glimpse of this language may give a fragment of a sense of what the Mohicans who lived here thought of the caves and hemlock trees of the Ice Glen or the hard rock maples on Monument Mountain.
The people who spoke Mohican in Stockbridge talked of the mountains as organisms, as unique as people. According to Lion Miles, a Stockbridge historian and linguist who has compiled the first dictionary of Mohican, the Mohican language had animate and inanimate words, much as French and Latin have male and female ones. Mountains are animate in Mohican.
Mountains have souls.

I've posted the head animation before. The red target is the medulla oblongata. I'm sure you, and many here already know that.
As you have said... Even if you could guarantee vaporizing it, there might be something else that causes the involuntary trigger pull.
In addition to it being a small target, it's invisible, it's covered by hair,a ball cap, a hoodie, whatever... And, it's moving.
Will your handgun ammo pierce the skull with no deflection, and vaporize the contents of the head in near proximity to the M.O.? A rifle bullet will, most likely... But I question a handgun round doing so.
Once the muzzle is off my child, THEN it's ON. But, frankly, if the guy puts his gun down... And starts walkin', he's free to go.
LEO was called before I ever started clearing the house. And honestly, I don't think it's wise to clear even your own home alone, so I probably wouldn't do that. But the OP gave the scenario, and I answered the original, with little embellishment.

Seems all the talk last week about the Dragons threatening the eight has frizzled away to nothing. Just goes to show Doust and his team are good at the PR and spin but the fact remains they have been short on recruitment of a few decent forwards all year. Dragons are just making up the numbers once again and without any concrete changes ahead chances are they will continue to reside at the bottom half of the table for the next few years yet.
I'll give you Harris, Bromwich J, Bromwich K, McLean, even Will Chambers as being more improved at Melbourne than Fonua, a nice enough squad player but hardly that exciting in attack; and who will disappear back to the Magoos when Justin O'Neill is firing again. (I've also got Kurt Mann ahead of him in the reckoning, even if Bellayache presently doesn't!).
For the Sharks... I'm guessing that Feki will come in for Gagan, Gallen for Graham, Arona for Lewis.
Gallen could be 1 more week away.
I think it's safe to say John Cartwright was pushed. He loves that club and would have stayed there forever if they let him.
Agree with you Luke. Cartwright is a champion
I can't imagine anyone who wants that job right now. Trying to keep players focused up at the Gold Coast is hard enough and then you add the club going in and out of financial turmoil every 12 months - it'd be a nightmare situation to manage.
Manly, Souths and Roosters with Penrith beating Melbourne and Cantebury for 4th spot via for and against. Nth QLD and Warriors to fill out the 8.
The race for the last spot in the four could be interesting.
The chooks really missed Jennings the last few weeks. His impact on that side is phenomenal.
I know it's a cliche, but it really does show how much of a difference quality outside backs make in a game.
He makes our halves look 1000% better.
100 % agree! Jenko's a big plus for the Chooks.

Economic Information Bulletin No. (EIB-29-1) 8 pp, September 2007
The increased food purchasing power offered by the Food Stamp Program can promote food security and improve the overall economic well-being of low-income households. Now, as Americans struggle with obesity and other diet-related health problems, there is interest in whether the program can be more effective in encouraging participants to make healthy food choices. ERS has compiled economic research to provide decisionmakers with information on the likely effects of various proposed strategies for improving the food choices of food stamp program participants. This overview summarizes the findings, which are presented in more detail in a series of individual briefs.

UT Health Center will sponsor a free seminar about gallstones on Sept. 19 in Gilmer
Tuesday, September 12, 2006
Do you suffer from gallstones? Maybe you think you might have gallstones, but aren't sure. You can have your questions answered at a free seminar sponsored by The University of Texas Health Science Center at Tyler on Tuesday, Sept. 19, in the hospital boardroom at ETMC-Gilmer, 711 N. Titus in Gilmer.
The informative seminar runs from noon until 1 p.m. and includes a complimentary lunch, said UTHSCT special events coordinator Dexter Jones.
John Aucar, MD, UTHSCT's chief of surgery, will talk about the symptoms of gallstones and what can be done to treat them, Jones said. Dr. Aucar is a Fellow of the American College of Surgeons, a Fellow of the International College of Surgeons, a Diplomate of the National Board of Medical Examiners, and is board certified in surgery.
Gallstones can cause serious problems if they become trapped in the bile ducts. Symptoms of gallstones include:
- steady pain in the upper abdomen that increases rapidly and lasts from 30 minutes to several hours;
- pain in the back between the shoulder blades;
- pain under the right shoulder; and
- nausea or vomiting.
Seating for the seminar is limited and reservations are required. To register for the seminar, call (903) 877-5122.

Curriculum vitae
I am interested in the systematics of the family Gyrinidae, commonly known as the whirligig beetles, performing alpha taxonomy within the group as well as using phylogenetics to answer and explore interesting questions about evolution and biogeography within the Gyrinidae. Specifically, my current work focuses on the tribe Dineutini within the Gyrinidae. The Dineutini contains the largest and most conspicuous members of the whirligigs and is composed of the genera
, and
This group is interesting from two aspects; taxonomically and biogeographically. Taxonomically the group has two of its five component genera with their monophyly in question, and three of the genera have been extensively divided into subgenera, whose monophyly have never been tested phylogenetically. Biogeographically this group is very interesting, especially in reference to the largest genus with the
is found in North America from Panama northward, throughout Africa, in to the Middle East, down to Southeast Asia, the Pacific Islands, New Guinea, and Australia. It is suspiciously missing from South America. To make matters even more interesting South America has two dineutine genera endemic to it:
. Of these, recent molecular evidence has suggested that
is nested within the primarily Australian and New Guinean genus
, which is absent from Africa. My phylogenetic work will hopefully reveal the interesting evolutionary histoy explaining these biogeographic relationships as well as clarifying the higher taxonomy of the Dineutini.
Another area of interest for me is the relationships of sexual selection and diversity within the whirligig beetles. Gyrinids are highly conserved ecologically and morphologically, except for those characters associated with sexual selection. My thesis work is also examining sexually selected characters in relation to species numbers, in order to ascertain a correlation between numerous sexually selected traits and increased species numbers. An important aspect of this is sperm diversity. Whirligig beetles exhibit a variety of sperm conjugation types. Sperm conjugation is a type of sperm competition strategy relatively rare among animal groups but appearing in a variety of forms within the family Gyrinidae.
Aside from the systematics of Gyrinidae I perform work in other aquatic beetle groups and have interests in aquatic beetle systematics as a broader whole. I first began aquatic beetle systematics work under
Dr. Andrew Short
at the University of Kansas working on small groups within the Hydrophilidae and have performed several projects within the Hydradephaga outside of the Gyrinidae. In the future I intend to continue work on aquatic beetle systematics but keeping the Gyrinidae as my primary focus.

What Teachers and Students Say
"The speakers were great–they really touched the audience. Many teachers went home and had a talk with their own children. So many wonderful responses. It was the talk of the lunch table the next day. Many teachers felt that this gave them the "recharging" they needed to keep active in dealing with this issue and make sure that our high school is safe for gay kids!"
"Excellent workshop! Those who attended are still talking about it and how 'simple' it is to do something to eradicate the negative comments and feelings surrounding gay youth! We want you back in the fall for an in-service workshop that lasts for an entire morning!"
"Many students told me that they were very moved by your honest emotion in coming to an understanding about this issue in your own life. It is important for people to see and hear that parental love is constant. You are doing important work educating young people in the best possible way to be accepting of all people."
"We liked having both a parent of a LGBT individual and a gay parent–it added a dimension often overlooked in discussions of LGBT issues in schools."
"This school desperately needed a session like this one."
Middle and High School Students
"This was the best class we had all year. I thought the two speakers were direct, honest, and realistic. Their message was based on real life experiences, and that they were so open as to share their personal experiences with us made us trust them. I felt like I could connect with what they were saying."
"I found this class extremely interesting because of the incredibly open and comfortable atmosphere our two PFLAG guest speakers created as soon as they began their presentation."
"It was good to hear a parent expressing pride in her gay child and risking harassment to express it."
"I used to dislike gay people and now realize I was just being stupid and ignorant."
"What I learned today made me think. I had heard people tell me this stuff before, but today it touched me more…. I feel that I'll use what I learned today. I'll remember it. I'll change some of the things I do."
"I feel like I said some bad stuff and I didn't care what anyone else's feelings were. I will not say any bad words to gays and homosexuals."

Key management in a large portion of ubiquitous sensor networks has been a challenge due to the limited capabilities of their wireless communicating and battery-powered sensors. Moreover, an attacker physically capturing even a few nodes hampers the entire network security by impersonating nodes to inject false data in an undetected manner. To efficiently protect from such impersonating by node capture, we propose a new dynamic key management framework particularly for large-scale clustered sensor networks. In the framework, different keying mechanisms, respectively, secure in-cluster, intercluster, and individual communication by refreshing keys on demand, while adaptively handling node addition and capture. Theoretic analysis and simulation results show that our proposed framework provides higher connectivity and security against impersonating than other existing studies do, for better trade-off with resource overheads.
1. Introduction
Wireless sensor networks (WSNs) of wireless communicating and battery-powered sensors have attracted attention from ubiquitous networking due to such sensors' cheapness and handy installation. In particular, for unmanned monitoring, these networks are often deployed in unattended and adversarial environments [1]. Here rises providing security against security attacks, which are more likely to incur in such WSNs due to the sensors' limited capabilities on communication, computation, and storage, as a key issue. Among varied security attacks introduced in [2], we particularly target impersonating by physical node capture because such an attack enables attackers to compromise all the secrets, such as cryptographic keys, of captured nodes and spread malicious data out over the entire network with impersonating the captured nodes by the obtained keys. Thus, as several studies [2–5] have already noted, any security strategies to be proposed should be highly resource-efficient as well as provide the basic security requirements: confidentiality, protection of the content of a packet; authentication, corroboration of the source of a packet; and integrity, ensuring that the content of a packet is unchanged during transmission.
To achieve all of them, a lot of security schemes have been proposed based on symmetric or asymmetric cryptography. Simply speaking, the difference between them is if the same key is employed both by a sender for encryption and by its receiver for decryption or not [4, 6]. Although asymmetric schemes generally provide stronger authentication [2, 4], symmetric key algorithms have been superior in WSNs for their light complexity [5, 7, 8]. For instance, one of typical sensors Tmote has 10 kb RAM, 48 kb flash memory, 1 mb storage, and 250 kbps communication bandwidth, which is insufficient to enable traditional asymmetric cryptography to work [9].
In the paper, we propose a new symmetric key-based security framework for efficiently secure communication in WSNs. To suggest an efficient data aggregation model for large-scale WSNs, we first assume that a WSN consists of a single very powerful base station (BS) and a number of clusters of regular sensors as in [10, 11]. Accordingly, as in Figure 1, our framework supports three different communication patterns invoked by the following three types of keys: a static individual key shared with BS; a one-time in-cluster key shared within a cluster; and a static intercluster key between two neighbouring nodes across different clusters. We demonstrate how different keying mechanisms for these keys work to cope with impersonating by node capture in the following organisation. Section 2 describes what assumptions we take first and introduces our proposed security framework in cluster-based WSNs of our interest. In Section 3, with designing the impersonating attack model, we provide theoretic analysis of our framework in several performance metrics. Section 4 compares the performances of ours with those of selected conventional key schemes. Finally, we conclude the paper in Section 5.
2. Our Proposed Security Framework
Our framework provides multiple keying mechanisms to support the three communication patterns, while giving confidentiality, authentication, and integrity. We first give several assumptions regarding WSNs of our interest; present the keying schemes to establish and manage each of individual, in-cluster, and intercluster keys with secure transmission employing the keys; and discuss how to handle node addition and eviction.
2.1. Network and Security Assumptions
In the paper, a WSN consists of a single BS and a number of static wireless sensors that are deployed as in [12]. Every time a helicopter stays in a different deployment point, it scatters a sensor subset, called a cluster. In such a cluster, every node knows all of its cluster members' IDs and directly or indirectly interacts with others in a hop-by-hop manner. One of them is safely announced as the cluster head, a local controller, to the other members. When a node newly joins one cluster after the initial deployment, the head is informed of its ID by BS and lets all the members know the ID as well before it is actually placed. Since any sensor does not know its immediate neighbours in advance, it attempts to find its neighbours and establish required keys shortly after its deployment. This keying phase is assumed to be fairly well protected. However, once a security attacker captures a node, it can obtain all of the node's cryptographic information. We also assume that the most feasible path from a source to its destination is selected and notified to all the on-path nodes by the clusterbased back-pressure routing algorithm of [13].
We illustrate our security framework using the next notations that appear in the rest of this discussion.(i)is the number of nodes in a WSN. (ii) is the number of clusters in a WSN. (iii) is the average size of a cluster. (iv) is the average number of a node's neighbours. (v) is the average number of border nodes, which relay messages to the outside of its cluster, in a cluster. (vi) and are principals for clusters. (vii) and are principals for sensor nodes. (viii) is a pseudorandom function (PRF) based on seed with key . (ix) is a one-way function (OWF) generating a one-way key from key . (x) is the individual key of node . (xi) for is a one-way key chain shared within cluster . (xii) is the base of node based on which utilises its key chain in its own manner. (xiii) is a packet sequence number, which increases as time goes by, of node . (xiv) is a one-time in-cluster key of node . (xv) is the intercluster keys of border node with border node of another cluster. (xvi) is the encryption of packet with key . (xvii) is the collision-free message authentication code (MAC) of packet with key . Given and with known , the receiver authenticates the sender and ensures 's integrity by confirming that the given can generate the same MAC value as the arrived . (xviii) is the concatenation of data and by concatenator .
2.2. Individual Key
Since individual communication with BS contains highly private information, such as new node's joining announcement by BS or any neighbour's misbehaviour report by a node, which can be detected by any anomaly-based intrusion detection system discussed in [14], one's individual key is only shared with BS to authenticate the source of such notification. These keys are assigned by BS prior to deployment as follows.
Key Predistribution. To assign a unique individual key to each node, BS first builds a symmetric key matrix of , where every key pair of and such that is identical. Every key is used to compute a distinct individual key for each member of cluster by . Before its deployment, every node is preloaded not only such an individual key but also for its cluster and to be utilised in the initial intercluster key establishment.
2.3. In-Cluster Key
We note that in-cluster communication most frequently occurs to exchange successive incoming percepts and to efficiently aggregate data. If a single cluster key is shared within a cluster for economical reasons, an adversary easily endangers the entire cluster by capturing only one node. Thus, we propose that a group of nodes sharing a key chain utilises all of the keys as each one's one-time encrypting keys in their own manners. One's current one-time key is derived only by its neighbours in its cluster, called in-neighbours, with its privately known base in advance and the current packet sequence number unless the base is compromised. This idea has, over the conventional key chain studies [1, 15, 16], the following additional advantages: strong key freshness, no need of key disclosure synchronisation, and no message overhead for direct key delivery.
Key Chain Predistribution. Before the initial deployment, BS generates and provides a unique one-way key chain of keys for every cluster based on OWF and key of the key matrix. As in TELSA, is constructed by , , and . To every member , BS randomly assigns neighbour-distinct base in , based on which has its own key use order as in Figure 2. Due to the hard-to-reverse nature of OWF, this generation-reversing key-use guarantees that any lower indexed key hardly implies higher indexed keys.
Neighbour Discovery and Base Exchange. After its deployment, every node first attempts to find its any neighbour by broadcasting its id, cluster ID , and random key index in in public as well as its base in private by key as (1). Receiver in the same cluster replies as (2). Otherwise, in another cluster does as (3) Having received packets as (3), becomes aware that it is a border node.
Rechaining and Key Chain Distribution. When member reports its key reference exhaustion on the currently shared key chain to the head of cluster or when any member is perceived as captured, the head generates key and new by recursions of . To propagate this key chain, conveys after encrypting it with its current of the old key chain as follows: Every receiver can generate the same key chain based on the arrived and passes it on to its in-neighbours in the same manner. As soon as a nonborder node forwards to others or a border node generates the new key chain, and the old key chain are immediately erased and every sequence number is reset to .
2.4. Intercluster Key
For packets crossing clusters, every pair of border nodes in two adjacent clusters, called interneighbours, should share a distinct pairwise key. So far, every node has been loaded keys of the key matrix and known if or not it is a border node. Every nonborder node immediately erases the keys because only border nodes make use of them to establish intercluster keys as follows.
Key Establishment. Every border node of cluster is given a series of pairs for border node of cluster after having received messages as (3). It can produce intercluster key for each . Simultaneously, also computes the same key, differently named for of , for the symmetry as . As soon as computing all the required intercluster keys, erases all the given keys.
2.5. Secure Transmission
Now, we present how these established keys practically secure in-cluster, intercluster, and individual communication as in (5) to (7), respectively: (i)Within a cluster, node sends another node or broadcasts packet by transmitting the 's encryption and MAC by its current with the current as (5). Any receiver privately obtains after deriving the with the previously known and the just arrived . (ii)Node of cluster always uses intercluster key to encrypt packet and produce its MAC when it sends to inter-neighbour as in (6). As also holds , is safely restored by . (iii)When BS individually informs node in cluster of packet , it transmits to the first node on a given path as in (7). Whereas the former two to address the destination are repeatedly decrypted and reencrypted by the on-path nodes including through a deal of in- and intercluster communication until they reach , the rest two are just carried during the transmission and only decrypted by . The opposite case of to BS reverses the course we have described.
2.6. Handling Node Addition
Before its deployment, new node is preloaded its individual key only shared with BS, cluster ID , unique base , and all of 's member ids as assumed. BS has enough time to inform 's members of 's joining and random key , temporarily used for 's key chain acquisition, in advance by letting 's head propagate the information. The notification is started as in (7), where and are, respectively, replaced by and . Then, first exchanges messages with its neighbours as in (8), and then (9) or (3) to obtain their bases and , recursions of : For every pair for interneighbour in cluster if exists, privately loads its generated intercluster key via a secure -to- path. As we assume that this entire node joining procedure is finished in , the temporal key is automatically dropped by every member after passes from when it is given.
2.7. Handling Node Eviction
A node is regarded to be evicted when its battery seems to be exhausted; when a large portion of its communication links do not work; or when it is detected as captured. Any of its neighbouring nodes perceiving one of the conditions announces it to the entire network. As soon as its uselessness is notified, its cluster members and inter-neighbours discard every related secret from their memory. In particular, if the node is captured as in the last case, the rest of its cluster should update the shared key chain as in the rechaining and key chain distribution. Also, its in-neighbours individually reselect and broadcasts a new base different from the previous one to their in-neighbours as in (1).
3. Analysis of Our Framework
In this section, we, in turn, analyse our framework in the following performance metrics: network connectivity, resiliency against impersonating attacks by node capture, and resource requirements.
3.1. Connectivity
Because of its deterministic nature, our framework achieves perfect connectivity between any two neighbouring nodes for both in-cluster and intercluster communication at the initialisation phase. This also holds for newly added nodes due to the prior node ID announcement by BS as in Section 2.6.
3.2. Resiliency
Since we view that active attacks, such as false data injection, most degrade network performances, we make the following strong attack model by node capture. (i)The attacker can retrieve all the information stored in a sensor node once it captures the sensor node. (ii)The attacker can capture a set of sensor nodes selectively in a WSN. (iii)The attacker ultimately aims at impersonating legitimate nodes to inject false data with compromised keys.
An attacker can purposely locate and capture sensors having more secrets as border nodes in our framework by selectively attacking such nodes. Such an attacker can impersonate only existing nodes whose ids are compromised because a new node with a falsified ID is thoroughly excluded due to the prior node ID announcement by BS. Thus, the resiliency against this attack is measured by estimating the fraction of total sensor nodes that properly impersonate id-known nodes by an attack, modeled as for every cluster in a network of nodes and clusters, where is the number of 's captured nodes, is the distinction rate amongst 's in-neighbours in , and is the bordering ratio of in . In this attack model, the greater or , the higher the selectiveness of the attack. Then, we formulate the overall impersonated fractions on in-cluster, intercluster, and individual communication, , , and , respectively, as follows:
The overall is the normalised sum of impersonated fractions over every cluster, , given by (10). In cluster , given , adversary behaves as follows:(i) completely impersonates every node of nodes,(ii)to impersonate each of 's in-neighbours with their compromised bases, should speculate its other in-neighbours than by as well as their sequence numbers by , for every ,(iii)to impersonate each of the rest members, should speculate its neighbours by , their bases by , and sequence numbers by ,
The three terms of the numerator of (10), respectively, represent each case given above. For intercluster and individual communication, we can simply count and normalise as in (11) and (12) since one captured node reveals only its individual key and additionally intercluster keys if it is a border node. We simulate our resiliency levels for the different communication patterns with those of alternatives given different key chain lengths in Section 4.2.
3.3. Resource Requirements
Storage. Because the key size is usually larger than any other secret as a node ID or a base, we discuss only the number of retained keys for storage overhead. After the initialisation, every node obtains a single individual key, , in-cluster keys of its key chain and additionally intercluster keys if it is a border node. Thus, the required storage of our framework is mainly due to the key chain length given .
Communication. The communication overhead for our security framework occurs between a neighbouring pair during initial keying, rekeying, and keying for a new node. At the initialisation, the pair exchanges only their ids and bases, whereas a seed key for a new key chain and new bases travel for re-keying. For a new node, the pair where one is the new node exchanges at most their ids, bases, a temporal or intercluster key, and the last key of the currently shared key chain as in Section 2.6.
Computation. In the initialisation, every node does times of MAC to securely obtain its in-neighbours' bases and additionally times of PRF to generate intercluster keys if it is a border node. To update the key chain, it restores the sent seed key by one MAC operation and generates a new key chain of recursions of OWF . Given a new node, its neighbours can verify its base or sent intercluster key by one MAC operation. The new node operates one MAC to extract the last key and recursions of to generate its needed key chain. Letting be the key size in bit, OWF consumes computation, whereas its inverting cost is [17]. PRF also has a similar overhead [18]. Since MAC is usually regarded as a kind of hash function as OWF [1], MAC has a similarly low computation complexity as well.
4. Comparison with Previous Studies
In this section, we compare the performances of our proposed framework with those of the following three selected conventional studies.
2KP (see [8]). BS has two key pools of and of keys and assigns two key sets, keys from the -pool and keys from the -pool, to each node in advance. As soon as every node is deployed, it broadcasts the key ID sequence of its -key set. Only pairs sharing one or more common keys can establish a pairwise key somehow computed by a PRF, and then every node drops its -key set. For node addition, a new node and its neighbours exchange the key ID sequences of their -key sets to establish their pairwise keys as before.
LOCK (see [19]). This utilises two layers of keys for clustered WSNs. BS communicates only with weakly trusted cluster key servers (KSes) with keys by assigning a unique subset of keys from combinations to each node before deployment. Every KS distributes its generated keys amongst its cluster members in the same manner. In both layers, each member establishes pairwise keys within its included group by exchanging their key ids. Additionally, every regular node shares backup keys with BS to report the compromise of its KS.
LEAP+ (see [1]). Initially, every node is preloaded the same set of keys, termed , by which can derive its own base key in session by . For to establish pairwise key with every neighbouring in session , it first broadcasts its ID and waits for the encrypted 's ID with presumed by . Then, derives as well and the pair individually computes the pairwise key by . After the session ends, every node erases and from its memory. Every node is also preloaded a unique one-way key chain of keys and transmits the last key as the current one-time key to its neighbours before it first attempts to broadcast. Then, every time it broadcasts a message, it uses the current one-time key to encrypt both the message and the next one-time key. The current one-time key is discarded after it is used in encryption or decryption.
In the following simulations, we vary only the number of used or stored keys, , , , , and , to see its impact while fixing the network parameters as , , , and .
4.1. Connectivity
As already stated, the deterministic key establishing methods in ours and LEAP+ guarantee perfect connectivity regardless of the number of keys.
Since 2KP has stably high resiliency with 200 selected keys from 10000 keys [8], we take that , , and . To see the cases with and without new nodes, we also consider , where and are, respectively, the numbers of initially deployed nodes and of newly added nodes such that . Respectively saying and , the connecting probabilities between any neighbouring pair after nodes, are deployed and the one after nodes are added we formulate the overall connectivity of 2KP, , as follows: In both (13) and (14), the second term of the right represents the probability that two nodes do not share any keys to form a secure connection.
Regarding that and , the connectivity of LOCK, , is generally given in two different cases as follows: The upper equation holds by the fact that one's key set has at least one common key with every other's key set if , whereas the key sharing probability for is given as or by its probabilistic nature. For , we take that to, respectively, offer 126, 120, 105, and 120 key combinations for storage efficiency in a 100-node cluster.
The comparison of direct pairwising connectivity amongst ours, 2KP, LOCK, and LEAP+ has given our setting is resulted as in Figure 3. As illustrated, our framework, LEAP+ and LOCK for , has the perfect connectivity. The connectivity of 2KP is highly sensitive with regardless of node addition. LOCK is more likely to share keys as the difference from to is smaller. Thus, we observe that our framework enhances network connectivity higher than 2KP and LOCK of regardless of the numbers of keys and of newly added nodes.
4.2. Resiliency
If nodes are captured in total, no nodes other than the captured nodes can be impersonated in 2KP and LEAP+. Since they do not keep the keys based on which neighbouring pairs establish their pairwise keys using a PRF, the pairwise keys are hardly discovered by unauthorised parties due to the randomness of PRF. For broadcasting in LEAP+, every node owns its one-way key chain as well as its neighbours' one-time broadcasting keys. Even though the attacker obtains such a broadcasting key, it is hard to derive its future broadcasting keys by the one wayness of OWF [17]. Similarly, our impersonated probability on individual communication is given by as well.
In LOCK, keys are always kept to establish pairwise keys with new nodes even though the keys are periodically updated. The fraction of total sensor nodes that is impersonated by captured nodes, , is given as follows: We say that is the minimum number of key combinations in cluster that captured nodes can restore. In other words, the attacker obtains at least distinct keys, which produces key combinations, from compromised keys. This means that at least nodes can be impersonated until they are detected as compromised.
Given total captured nodes in for in for every cluster , the average resiliency comparison work over 100 simulations is shown as in Figure 4. More specifically, we consider high selective attacks for in and in for our framework and the perfectly connected cases of LOCK as . Whereas the impersonated probabilities of ours, 2KP, and LEAP+ are under or around for every , LOCK has weaker resiliency on average with any . Thus, we observe that, regardless of the number of retained keys, our proposed framework similarly works as 2KP and LEAP+ known for the strongest resiliency do against impersonating by node capture.
4.3. Resource Requirements
Now, we compare our framework with 2KP, LOCK, and LEAP+ in three resource overhead metrics: storage, communication, and computation. Every analysed overhead is represented by the big notation to see its maximum complexity even in the worst case.
Storage. Table 1 provides the storage overheads of the selected keying frameworks. Regarding that stands for the size of key in bit, the different storage requirements to nonborder and to border nodes in our framework are given as stated in Section 3.3. By 2KP, every node is preloaded keys from the -pool for new nodes and shares pairwise keys with neighbours. In LOCK, every KS keeps keys for the BS-KSes communication and keys for its cluster communication, whereas every regular node stores keys to communicate with as well as keys as its KS does. Any group member establishes pairwise keys with its neighbours whatever the group is. LEAP+ initially assigns every node keys to establish pairwise keys with any nodes added in any session ≤ and a -length key chain to broadcast. Both types of keys are dropped just after they are used. Usually, of 2KP and and of LEAP+ take larger values for high connectivity and network longevity, respectively. Thus, on the storage overhead, our framework is superior to 2KP and LEAP+ but is not to LOCK in our simulations, where the cases of LOCK with smaller and achieve better resiliency than those with large and as in Figure 4.
Communication. While assuming that the key size, , is greater than node ids, key ids, bases, and the MACs of all of these without losing generality, we present the communication overheads required between a neighbouring pair for each of initial keying, rekeying,and keying for a new node by the different studies as in Table 2. For any keying course, our keying framework consumes communication sources with a single key with its MAC, two bases with their MACs, or two node ids as discussed in Section 3.3. Similarly, a neighbouring pair exchanges associated node ids or a broadcasting key with its MAC in LEAP+. By contrast, in 2KP and LOCK, every node broadcasts the sequence of their own key ids as needed to find neighbours having common keys. Since the broadcasting key delivery of LEAP+ more often occurs than our rechaining, our framework reduces the communication overheads of all the keying phases over 2KP, LOCK, and LEAP+.
Computation. All the complexities required to chain keys by an OWF, to produce an MAC by a hash function, and to generate a pairwise key by a PRF can be regarded to be negligible [1, 8]. Thus, the security frameworks without the key ID comparison, ours and LEAP+, have lower computation overheads than 2KP and LOCK do.
Although our framework does not achieve the least storage overhead, it is fairly competitive because the resource consumption of wireless sensor nodes is usually dominated by communication [20].
5. Conclusion
In the paper, we have proposed a new dynamic keying framework for large-scale clustered WSNs, widely employed to implement ubiquitous sensor networks. In the framework, different keying mechanisms, respectively, not only protect in-cluster, intercluster, and individual communication but also effectively handle node addition and eviction. Our proposed key-use ordering mechanism of a cluster-shared one-way key chain, illustrated in Figure 2, and intercluster key establishment using the preloaded key matrix achieve perfect connectivity as well as well protect wireless sensors from impersonating by node capture with low resource overheads. Such our claims have been discussed by the given theoretic analyses and varied simulations. As one of extensions for this work, we may raise energy efficiency and practicability by utilizing environment energy and considering crosslayer networking as in [21].

A Farewell from Senior Duncan "Diesel" MacDonald-Korth
Wednesday, May 17, 2011
Duncan MacDonald-Korth reporting here on what will be my last blog as an Oregon student-athlete.
First off, I would like to thank everyone that came out to my senior day- our match against the Huskies. It was a very meaningful moment to me personally, and we had the largest crowd in recent memory. It was great to finish my career at home in front of all of you fantastic Duck fans!
As many of you know, Alex Rovello and Robin Cambier made a big splash down at the Pac-10 Championships in Ojai, California. Both had huge first round wins- Rovell over Cal's Konigsfeldt and Cambier over Washington's Kildahl. To back it up Cambier went to a third set with the defending NCAA Individual Champion, Stanford's Bradley Klahn before coming up just short. However, these should be considered fantastic accomplishments and a sign of great things to come for these talented young players and the Ducks' program as a whole!
The guys have now begun offseason training and have been ramping up the fitness. Our definitive goal is to become the best conditioned team in the Pac-12—no one will be fitter than the Ducks! Both the coaches and the UO strength and conditioning staff have been instrumental in getting us into the best shape of our lives.
On a personal note, I'd like to thank all the Oregon fans for faithfully attending and supporting Duck tennis throughout my career. With such exceptional players on the team, I hope you are as hopeful and positive as I am about the future success of the program!

ingredient information
Sodium Caseinate
Sodium Caseinate Sodium Caseinate is a modified protein extracted from milk. It has no odor or taste and is used as a thickening and whitening agent in dairy products. The protein component utilizes emulsification, water absorption, gelling, and stabilization properties. It is used in dairy non-creamers to act as a creamy, white dairy substitute without the lactose that people who are lactose-intolerant cannot digest. Because of its large difference between the "milk derivative� that is sodium caseinate and real cream or milk, it is considered non-dairy. There is controversy whether sodium caseinate still has all the nutritional benefits that milk has because it is non-dairy. It is also a source of free glutamic acid. See monosodium glutamate (MSG).

A wedding dress is likely to be the most expensive item of clothing the bride has ever worn.
It is easy to get carried away, but a realistic budget should be set.
Wedding dresses vary hugely in price so it is sensible to only try on those that are affordable.
Once the dress has been chosen, the shop will require a deposit - normally 50 per cent of the total cost.
The balance will be due on the day of collection, but expected alteration costs must be discussed.
Alterations are often charged by the hour and can really add up. Shops may offer a staggered payment option to make more expensive dresses affordable.
If a made-to-measure dress is required, it is often more expensive.

A 10-year-old girl was impaled with a steel bar in a sledding accident in northern Maryland on Monday. A snow day off from school turned dangerous for a Jarrettsville youngster who was enjoying the morning snowfall sledding downhill with her friends, according to the New York Daily News on Feb. 3.
The little girl was sledding when she fell backwards and became impaled on a steel rod that went through the left side of her back. She had landed on the snow concealed steel bar after coming downhill. Jarrettsville Volunteer Fire Company Chief Rudy Walter said that the steel bar was about "an inch and a half or so in diameter." He said. "It was a pretty good size."
The girl's parents, who were with her in the area where she was sledding, called 911. When the emergency workers arrived they used a saw to extract the 10-year-old from the metal bar, which took them about 28 minutes to do. The girl was removed from the bar, but she still had six inches sticking out of her back.
Walter said the young girl was in a little bit of shock, but besides letting out a yell or a scream periodically, she remained calm and let the rescue staff do their job. She was transported to the hospital with the metal bar protruding from her back, for the doctors to remove.
She impressed the rescue team for being so brave through the ordeal. The girl, whose name was not released, is in stable condition today in John Hopkins Children's Hospital.

We purchased a horse that was an expolo horse. She was injured during the season and was as unfortunately is the case sometimes was sold at auction. We think she maybe Argentine Thoroughbred but are not sure. She does not have a lip tattoo as is common with US thoroughbreds. She is branded however. She has a S with an upwards arrow thru it on her left hip and on her rump she has te numbers 4 onone side of her tail and 703 on the other. She is approximately 5-7 years old. We love her to death and are turning her into a trail riding horse, but we are very curious to try to find her origns. She was shown in the US but we think she was imported.....
Any help on the brand would be helpful.

Hi, I too am desperately trying to find out history on my ex polo pony. She is also branded 6 on left side of her tail and a 3 on the right. I think she may have come from Venezuela, but not sure. I hope you have success in your search. Sharon x
If it wasnt for horses, Id be soooo rich, but soooo miserable!
Thanks for your well wishes. This is a hard thing to track because you really don't even know the breed. Ugh!!! I hope you many more years together. Happy trails!
Have you checked with anyone in the US about your polo horse. Try contacting the Aiken, South Carolina polo association. We have contacted each state with the exception of Texas which is on a county level with brand registries.... They have a lot of polo there, and the gentleman that responded to me is passing her pictures around polo matches for me. He told me that her brand was definitely from Argentina. He was very knowledgeable about polo ponies and super nice to us. So we are getting closer to finding out the rest of her story. Good luck!!!

Actions today within the Eurozone took on a Kabuki theater like presence when on Aug. 13, several European nations cried foul and headed to the World Trade Organization (WTO) to protest economic sanctions laid upon them by Russia, and which are now seriously affecting their agricultural exports. What is perhaps the most ironic in all of this, is that it is not Russia who is the originator of problems for farmers in Spain, Greece, Finland, and Poland, but instead the issue lies primarily at the feet of Washington, D.C., and the United States who started the trade war with the Eurasian power, and has brought the Eurozone nations into the conflict as collateral damage.
Last week when Russian President Vladimir Putin signed several economic sanctions into law restricting the importing of foodstuffs by the U.S. and any nation who went along with Washington imposed sanctions, the Eurasian leader specifically detailed that he would remove these sanctions for any country that willingly rebelled against U.S. aggression, and sought free trade outside of U.S. imposed policies directed at Russia.
Unfortunately for many countries tied strongly to the U.S. dollar and financial system, their being put between a rock and a hard place is now threatening their very economies, and potentially as well, their unemployment rates.
Spanish Agriculture Minister Isabel Garcia Tejerina said the restrictions have prompted her ministry to convene a meeting with the European Commission in Brussels on Thursday.
The Spanish government has estimated that agricultural losses will amount to €337 million, or about 1.8 percent of Spanish exports. Other groups, like Spain's opposition Socialist Party, have estimated the losses to be higher- €581 million. - Zerohedge
The largest Finnish dairy producer Valio sent a forced leave of the staff with factories working for export to Russia.
Poland's agriculture minister went on television to announce the country was taking action against Russia's new import ban. "We believe Russia has broken international law in both its embargo against Poland and its embargo against the EU," Marek Sawicki said.
Russia banned the import of Polish fruit and vegetables in early August - a move Sawicki said would cost Poland 0.6 percent of GDP.
As opposed to a strategy of direct assault against the United States over sanctions imposed upon them for their actions in Ukraine and the Crimea, Russia is focusing instead on America's allies who can ill afford to withstand long term import sanctions against their economy, and are relying upon Eurozone nations to turn upon their financial master to demand an end to the growing economic 'Cold War'.
The stakes are extremely high in this new battle between superpowers, and like during the Cold War of the 20th century, external nations allied to both sides more often than not felt residual consequences from the political, military, and economic actions taken in this ideological and geo-political conflict. But unlike the Cold War that ended just 23 years ago, this one is directed more at the United States than it is at Russia, and the chances of America succumbing to economic collapse are much greater than when the old Soviet Union did to to end the prior conflict.

Yes Virginia, Health Insurance Is Different From Broccoli
The Supreme Court will soon rule on challenges to the Affordable Care Act ("ACA"). The central questions before the Court are: 1) is the "Individual Mandate" which requires every U.S. resident to purchase health insurance or pay a fine unconstitutional, and 2) if yes, does the entire ACA need to be struck down and sent back to Congress, or only parts of it?
Virginia and 25 other states challenging the law argue that the requirement that all Americans buy health insurance — known as the 'individual mandate' — is unconstitutional. This legal wrangling does nothing to solve the health care problem. Health care is becoming unaffordable for the country as a whole, which means that, as health care costs climb from 17% of GDP in 2010 to 20%+ in 2020, people in lower income brackets get squeezed progressively out of the health care system (except for the very poor, who qualify for Medicaid). The rest get paupered (more).
At the current cost levels, the only way to have an inclusive health care system is for everyone to share the cost (we can argue about who pays how much); every other advanced country takes this approach. In the ACA, the individual mandate together with the rules about how much premium discrimination can occur do this: everyone including the young, healthy "invincibles" (or, as some say, "generation Y-bother") makes a contribution. On this basis, broad coverage can be achieved and, with subsidies, insurance cost is held to 10% of income.
The legal debate is whether requiring a person to purchase insurance exceeds Congress' constitutional authority to regulate "interstate commerce": "it would be like requiring everyone to purchase broccoli". I'm no lawyer, but the difference is clear to me: broccoli is an inexpensive veggie that you can choose to eat or not. Health care is a complex national system that is so vital and expensive, it has been a national issue for a generation. The federal government clearly has authority to tax and spend. It could finance inclusive health via a single payer approach. The ACA tries to achieve the same end by extending the existing system of private insurance and employer sponsorship, because most people are comfortable with their health care and don't want to change. The real debate should be: what's the best way to fund inclusive health care?
And, none of the Capitol Hill players (including the Supremes) here are talking about the submerged part of the iceberg: cost reform. A major force that makes U.S. health care expensive is state-by-state regulation of major parts of the system such as health insurance and professional licensing: this reduces competition by keeping out efficient national providers and/or adds the cost of regulatory compliance in every state. And, it helps makes health care markets oligopolistic: even in a large region like Boston (#10 U.S. metro area), two big hospital organizations and a three big insurers dominate the health care economy. Here's a legal issue to which Congress and the Court could add value. Regrettably, the debate is focused on fine legal distinctions.
Our health care system and because of it our entire economy are at a watershed. Winston Churchill had wonderful words for such situations, like: "These are the times that try men's souls." (Those were more sexist times.) His observation on our health care legal drama in the Supreme Court might be: "Never have so few … done so little … for so many."

I have followed your series with interest on health care and appreciate your even handed perspective on this very complex subject.
However, I wish you would have spent more time discussing the concerns about the Affordable Care Act posed by Supreme Court Justice Anthony Kennedy, which relate to the Federal Government and its relationship with the governed. This is an issue that transcends the health care debate in my opinion and is unlike the power Congress has to tax because with the law, Congress is mandating that an individual BUY something vs support the Federal Govt (as in taxes).
With the ACA, says Kennedy the US federal government "is telling an individual he has the obligation he must act" and purchase insurance.
"That threatens to change the relationship between the government and the individual in a profound way," Kennedy said. (see: http://www.cnn.com/2012/03/27/justice/scotus-health-care/index.html

NASHVILLE, Tenn. (Ivanhoe Newswire) -- For most kids, playing on the playground is a great place to have fun and one of the best ways to learn how to interact with other kids. However, for the 1 in 68 kids with autism, playgrounds can cause stress. Autism can hinder a child's ability to socialize. Now research is showing how we can change that.
These kids are going undercover in the name of science.
8 year old researcher, Calvin Hawes told Ivanhoe, "We're trying to like play with the kids and have fun. Like it's a normal day."
Psychiatry Professor at Vanderbilt University, Blythe Corbett, PhD, is leading the study and looking at how children with autism spectrum disorder play and interact with typically developing kids.
Corbett told Ivanhoe, "So we can better understand what things help them to interact but also what things are getting in the way of being able to play with others."
To test this, researchers took saliva samples from kids with ASD, like Ben, to measure the stress hormone cortisol.
"We wouldn't be able to tell from a lot of our kids, how stressed they really are when they are interacting with others," said Corbett.
Higher cortisol means Ben's less motivated to play with other kids.
Ben Solsvig, who has autism, told Ivanhoe, "It depends on how fun they are. I wouldn't want to play with a kid if he's all boring."
"The good news is though, that all it takes is a simple invitation for a peer to invite them, to ask them to play. And that can significantly improve their willingness to engage with others," Corbett said.
A simple invitation could make all the difference for a child.
Dr. Corbett says the study highlights the importance of bringing typically developing peers together with kids with autism spectrum disorder in all social settings. Kids with ASD are then able to learn that it's safe to interact with others.
The research was funded by the national institute of mental health.

A man who swallowed a fork as the result of a drunken bet with his buddies ended up at a local emergency room with stomach pain. He told the doctors that he was having a hard time swallowing and his stomach was hurting, but he first neglected to tell them about the silverware piece he just ingested, according to New York Daily News on March 27.
When Radu Calincescu finally told the Romanian doctors that he swallowed a fork, they pretty much knew this already from the X-ray they took. The patient had come to his senses by then and had started to worry that the fork might puncture one of his vital organs.
The doctor's told Calincescu that while this was basically a very stupid stunt, the fork hadn't punctured any major organs. They told him that he would need to go home and wait for the fork to pass naturally.
If this fork didn't dislodge and come out in a bowel movement within a week, he was to go back to the hospital for another X-ray. At this time he'd be looking at the possibility of surgery to remove the eating utensil from his stomach if it didn't move.
Either way that fork makes its way out of the man's stomach is going to be painful. The guy learned his lesson though, he admits that swallowing a fork is just not a good idea.

Eski mezarlıkların mezar taşları

*Sproiiiiiing!* I like it ^^
A separate question: a friend is keeping a Helix aspersum as a pet. After a mating about 2-3 weeks ago, a bit of tissue protruded from the pneumostome. It was whitish and stuck there until recently when it came off. The snail appears to be fine. Do know now what the tissue could be? I'm guessing a spermatophore. I have a photo if that would help.
A spermatophore would be at the genital opening, which is posterior to the pneumostome. The thing you saw could have been a "love dart", but those things are as hard as the shell itself.
